Description
Defining Capital Budgeting
Capital budgeting, which is also called "investment appraisal," is the planning process used to determine which of an organization's long-term investments, such as new machinery, replacement machinery, new plants, new products, and research development projects, are worth pursuing. It
is to budget for major capital investments or expenditures.
Major Methods
Many formal methods are used in capital budgeting, including the techniques as follows:
- Net present value
- Internal rate of return
- Payback period
- Profitability index
- Equivalent annuity
- Real options analysis
Net Present Value
Net present value (NPV) is used to estimate each potential project's value by using a discounted cash flow (DCF) valuation. This valuation requires estimating the size and timing of all the incremental cash flows from the project. The NPV rate greatly affects the discount rate, so selecting the proper rate–sometimes called the hurdle rate–is critical to making the right decision.
This should reflect the riskiness of the investment, typically measured by the volatility of cash flows, and must consider the financing mix. Managers may use models, such as the CAPM or the APT, to estimate a discount rate appropriate for each particular project and use the weighted average cost of capital(WACC) to reflect the financing mix selected. A common practice in choosing a discount rate for a project is to apply a WACC that applies to the entire firm, but a higher discount rate may be more appropriate when a project's risk is higher than the risk of the firm as a whole.
Internal Rate of Return
The internal rate of return (IRR) is defined as the discount rate that gives a net present value (NPV) of zero. It is a commonly used measure of investment efficiency.
The IRR method will result in the same decision as the NPV method for non-mutually exclusive projects in an unconstrained environment, in the usual cases where a negative cash flow occurs at the start of the project, followed by all positive cash flows. Nevertheless, for mutually exclusive projects, the decision rule of taking the project with the highest IRR, which is often used, may select a project with a lower NPV.
One shortcoming of the IRR method is that it is commonly misunderstood when conveying an investment's actual annual profitability. Accordingly, a measure called "Modified Internal Rate of Return (MIRR)" is often used.
Payback Period
In capital budgeting, the payback period refers to the period of time required for the return on an investment to "repay" the sum of the original investment. The payback period intuitively measures how long something takes to "pay for itself." All else being equal, shorter payback periods are preferable to longer payback periods.
The payback period is considered a method of analysis with serious limitations and qualifications because it does not account for the time value of money, risk, financing, or other important considerations, such as opportunity cost.
Profitability Index
The profitability index (PI), also known as the profit investment ratio (PIR) and value investment ratio (VIR), is the ratio of payoff to investment of a proposed project. It is a useful tool for ranking projects because it allows you to quantify the amount of value created per unit of investment.
Equivalent Annuity
The equivalent annuity method expresses the NPV as an annualized cash flow by dividing it by the present value of the annuity factor. It is often used when comparing investment projects of unequal lifespans. For example, if project A has an expected lifetime of seven years, and project B has an expected lifetime of 11 years, it would be improper to simply compare the net present values (NPVs) of the two projects unless the projects could not be repeated.
Real Options Analysis
The discounted cash flow methods essentially value projects as if they were risky bonds, with the promised cash flows known. However, managers will have many choices of how to increase future cash inflows or to decrease future cash outflows. In other words, managers get to manage the projects, not simply accept or reject them. Real options analysis tries to value the choices–the option value–that the managers will have in the future and adds these values to the NPV.
These methods use the incremental cash flows from each potential investment or project. Techniques based on accounting earnings and accounting rules are sometimes used. Simplified and hybrid methods, such as payback periods and discounted payback periods, are also used.
Key Points
- Capital budgeting, which is also called investment
appraisal, is the planning process used to determine whether an
organization's long term investments, major capital, or expenditures are
worth pursuing.
- Major methods for capital budgeting include Net present value, Internal rate of return, Payback period, Profitability index, Equivalent annuity and Real options analysis.
- The IRR method will result in the same decision as the NPV method for non-mutually exclusive projects in an unconstrained environment; Nevertheless, for mutually exclusive projects, the decision rule of taking the project with the highest IRR may select a project with a lower NPV.
Terms
- Modified Internal Rate of Return – the modified internal rate of return (MIRR) is a financial measure of an investment's attractiveness. It is used in capital budgeting to rank alternative investments of equal size. As the name implies, MIRR is a modification of the internal rate of return (IRR) and, as such, aims to resolve some problems with the IRR.
- APT – in finance, arbitrage pricing theory (APT) is a general theory of asset pricing that holds, which holds that the expected return of a financial asset can be modeled as a linear function of various macro-economic factors or theoretical market indices, where sensitivity to changes in each factor is represented by a factor-specific beta coefficient.
Example
- Payback period: For example, a 1000 investment which returned 500 per year would have a two year payback period. The time value of money is not taken into account.

The Goals of Capital Budgeting
The main goals of capital budgeting are not only to control resources and provide visibility but also to rank projects and raise funds.
Budgeting provides a forecast of revenues and expenditures, constructing a model of how a business might perform financially if certain strategies, events, and plans are carried out. It enables the actual financial operation of the business to be measured against the forecast and establishes the cost constraint for a project, program, or operation.
Budgeting helps to aid the planning of actual operations by forcing managers to consider how conditions might change and what steps should be taken in such an event. It encourages managers to consider problems before they arise. It also helps coordinate the activities of the organization by compelling managers to examine relationships between their own operations and those of other departments.
Other essential functions of a budget include:
- To control resources.
- To communicate plans to various responsibility center managers.
- To motivate managers to strive to achieve budget goals.
- To evaluate the performance of managers.
- To provide visibility into the company's performance.
Capital Budgeting, as a part of budgeting, more specifically focuses on long-term investment, major capital, and capital expenditures. The main goals of capital budgeting involve:
Ranking Projects
The
real value of capital budgeting is ranking projects. Most organizations have many projects that could potentially be financially rewarding. Once determined that a particular project has exceeded its hurdle, it should be ranked against peer projects (e.g., from highest to lowest Profitability index). The highest-ranking projects
should be implemented until the budgeted capital has been expended.

Private Equity Private equity firms, such as NBGI, provide funds for companies that are unable or uninterested in obtaining funds publicly.
Raising Funds
When a corporation determines its capital budget, it must acquire funds. Three methods are generally available to publicly traded corporations: corporate bonds, preferred stock, and common stock. The ideal mix of those funding sources is determined by the firm's financial managers and is related to the amount of financial risk that the corporation is willing to undertake.
Corporate bonds entail the lowest financial risk and, therefore, generally have the lowest interest rate. Preferred stock has no financial risk, but dividends, including all in arrears, must be paid to the preferred stockholders before any cash disbursements can be made to common stockholders; they generally have interest rates higher than those of corporate bonds. Finally, common stocks entail no financial risk but are the most expensive way to finance capital projects. The Internal Rate of Return is very important.
Capital budgeting is an important task as large sums of money are involved, which influences the firm's profitability. Plus, a long-term investment, once made, cannot be reversed without significant loss of invested capital. Because of the time factor involved, the implications of long-term investment decisions are more extensive than those of short-run decisions; capital budgeting decisions are subject to a higher degree of risk and uncertainty than short-run decisions.

Goals of Capital Budgeting The main goal of capital budgeting is to rank projects.
Key Points
- Basically, the purpose of budgeting is to provide a forecast of revenues and expenditures and construct a model of how business might perform financially.
- Capital Budgeting is most involved in ranking projects and raising funds when long-term investment is taken into account.
- Capital budgeting is an important task as large sums of money are involved and a long-term investment, once made, can not be reversed without significant loss of invested capital.
Terms
- Preferred Stock (also called preferred shares, preference shares or simply preferreds) – an equity security with properties of both an equity and a debt instrument, and is generally considered a hybrid instrument.
- Common Stock – is a form of corporate equity ownership, a type of security.
Accounting Flows and Cash Flows
Capital budgeting requires a thorough understanding of cash flow and accounting principles, particularly regarding valuing processes and investments.
Accounting Flows
Accounting is the process of identifying and transposing business transactions into permanent legal records of a business's operations and capital flows. The International Accounting Standards (IAS) and the Generally Accepted Accounting Principles (GAAP) are legislative descriptions of expectations and norms within the accounting field.
When it comes to the capital flows in accounting, it is easiest to visualize it based on each type of item:

Accounting Flows This chart is useful for examining the trajectory of accounting flows as they apply to different types of line items.
This chart is useful for examining the trajectory of accounting flows as they apply to different types of line items. Understanding how to report each type of asset and the impacts these asset changes have on income statements, balance sheets, and cash flow statements is important in accurately depicting accounting flows.
Cash Flows
Cash flow is one element of accounting flows and is particularly important to understanding capital budgeting. A cash flow describes the transmission of payments and returns internally and/or externally as a byproduct of operations over time. Conducting cash flow analyses on current or potential projects and investments is a critical aspect of capital budgeting. It determines the profitability, cost of capital, and/or expected rate of return on a given project, organizational operation, or investment.
Cash flow analyses can reveal the rate of return, or value of the suggested project, by deriving the internal rate of return (IRR) and the net present value (NPV). They also indicate overall liquidity or a business's capacity to capture existing opportunities by freeing capital for future investments. Cash flows will also underline overall profitability, including, but not limited to, net income.
Cash flows consolidate inputs from the following activities:
- Investing activities – Payments related to mergers or acquisitions, loans made to suppliers or received from customers, and the purchase or sale of assets are all considered investing activities and tracked as incoming or outgoing cash flows.
- Operating activities – Operating activities can be quite broad,
incorporating anything related to the production, sale, or delivery of a product or service. This includes raw materials, advertising,
shipping, inventory, payments to suppliers and employees, interest payments, depreciation, deferred tax, and amortization.
- Financing activities – Financing activities primarily revolve around cash inflows from banks and shareholders and outflows via dividends to investors. This includes payment for the repurchase of company shares, dividends, net borrowing, and net repayment of debt.
Key Points
- Accounting revolves around tracking the inflows and outflows of assets, capital, and resources for an organization to adhere to legal and investor expectations.
- When measuring the impact of assets, liabilities, and equity, it is useful to know in which situations to debit or credit the line item based upon the flow of capital.
- Cash flows analyses, such as the internal rate of return (IRR) or the net present value (NPV) of a given process, are core tools in capital budgeting for understanding and estimating cash flows.
- Cash flow analyses can include investing, operating and financing activities.
Terms
- Internal Rate of Return (IRR) – a calculation that makes the net present value of all cash flows (positive and negative) from a particular investment equal to zero. It can also be described as the rate which will make an investment break even.
- Net Present Value (NPV) – this calculation takes all future cash flows from a given operational initiative, and discounts them to their present value based on the weighted average cost of capital.
Ranking Investment Proposals
Several methods are commonly used to rank investment proposals, including NPV, IRR, PI, payback period, and ARR.
The most valuable aim of capital budgeting is to rank investment proposals. To choose the most valuable investment option, several methods are commonly used:

Investment Proposal Choosing the best investment proposal for business.
Net Present Value (NPV):
NPV can be described as the "difference amount" between the sums of discounted cash inflows and cash outflows. In the case when all future cash flows are incoming, and the only outflow of cash is the purchase price, the NPV is simply the PV of future cash flows minus the purchase price (which is its own PV). The higher the NPV, the more attractive the investment proposal.
NPV is a central tool in discounted cash flow (DCF) analysis and is a standard method for using the time value of money to appraise long-term projects. Used for capital budgeting and widely used throughout economics, finance, and accounting, it measures the excess or shortfall of cash flows in present value terms once financing charges are met.
\( NPV(i, N) = \Sigma ^N _ {t=1} \dfrac{R}{1+i)^t} \)
NPV formula: Each cash inflow/outflow is discounted back to its present value (PV). Then, they are summed. Therefore, NPV is the sum of all terms.
In financial theory, if there is a choice between two mutually exclusive alternatives, the one yielding the higher NPV should be selected. The rules of decision-making are:
- When NPV > 0, the investment would add value to the firm, so the project may be accepted.
- When NPV < 0, the investment would subtract value from the firm, so the project should be rejected.
- When NPV = 0, the investment would neither gain nor lose value for the firm. We should be indifferent to whether to accept or reject the project. This project adds no monetary value. Decisions should be based on other criteria (e.g., strategic positioning or other factors not explicitly included in the calculation).
An NPV calculated using variable discount rates (if known for the duration of the investment) better reflects the situation than one calculated from a constant discount rate for the entire investment duration.
Internal Rate of Return (IRR)
The internal rate of return on an investment or project is the "annualized effective compounded return rate" or "rate of return" that makes the net present value (NPV as NET*1/(1+IRR)^year) of all cash flows (both positive and negative) from a particular investment equal to zero.
IRR calculations are commonly used to evaluate the desirability of investments or projects. The higher a project's IRR, the more desirable it is to undertake the project. Assuming all projects require the same amount of up-front investment, the project with the highest IRR would be considered the best and undertaken first.
Profitability Index (PI)
It is a useful tool for ranking projects because it allows you to quantify the amount of value created per unit of investment. The ratio is calculated as follows:
Profitability index = PV of future cash flows / Initial investment
As the value of the profitability index increases, so does the financial attractiveness of the proposed project. Rules for selection or rejection of a project:
- If PI > 1, then accept the project
- If PI < 1, then reject the project
Payback Period
Payback period intuitively measures how long it takes something to "pay for itself." All else being equal, shorter payback periods are preferable to longer payback periods. The payback period is widely used for its ease of use despite the recognized limitations: The time value of money is not considered.
Accounting Rate of Return (ARR)
The ratio does not consider the concept of the time value of money. ARR calculates the return generated from the net income of the proposed capital investment. The ARR is a percentage return. Say, if ARR = 7%, then it means that the project is expected to earn seven cents out of each dollar invested. If the ARR is equal to or greater than the required rate of return, the project is acceptable. If it is less than the desired rate, it should be rejected. When comparing investments, the higher the ARR, the more attractive the investment. Basic formulae:
ARR = Average profit / Average investment
Where: Average investment = (Book value at beginning of year 1 + Book value at end of user life) / 2
Key Points
- The higher the NPV, the more attractive the investment proposal.
- The higher a project's IRR, the more desirable it is to undertake the project.
- As the value of the profitability index increases, so does the financial attractiveness of the proposed project.
- Shorter payback periods are preferable to longer payback periods.
- The higher the ARR, the more attractive the investment.
Terms
- Time Value of Money – the value of money, figuring in a given amount of interest earned over a given amount of time.
- Discounted Cash Flow – in finance, discounted cash flow (DCF) analysis is a method of valuing a project, company, or asset using the concepts of the time value of money.
Reinvestment Assumptions
NPV and PI assume reinvestment at the discount rate, while IRR assumes reinvestment at the internal rate of return.
Reinvestment Rate
To some
extent, the selection of the discount rate is dependent on the use to
which it will be put. If the intent is simply to determine whether a
project will add value to the company, using the firm's weighted average cost of capital
may be appropriate. If trying to decide between alternative investments
to maximize the firm's value, the corporate reinvestment
rate would probably be a better choice.

Reinvestment to expand business.
\( \text{Year 3 Reinvestment Factor } = \dfrac{\text{Year 3 Total Distribution }\times \text{ Year 2 Reinvestment Factor}}{\text{Year 3 Share Price}} + 1 \)
Reinvestment Factor Describe how the reinvestment factors are related to total return.
NPV Reinvestment Assumption
A key variable of this process is the rate used to discount future cash flows to the present value. A firm's weighted average cost of capital (after tax) is often used, but many people believe that higher discount rates are appropriate to adjust for risk or other factors. A variable discount rate with higher rates applied to cash flows occurring further along the time span might be used to reflect the yield curve premium for long-term debt.
Another approach to choosing the discount rate factor is to decide the rate at which the capital needed for the project could return if invested in an alternative venture. Related to this concept is the use of the firm's reinvestment rate. The reinvestment rate can be defined as the rate of return for the firm's investments on average.
When analyzing projects in a capital-constrained environment, it may be appropriate to use the reinvestment rate rather than the firm's weighted average cost of capital as the discount factor. It reflects the opportunity cost of investment rather than the possibly lower cost of capital.
PI Reinvestment Assumption
The profitability index assumes that the cash flow calculated does not include the investment made in the project, which means PI reinvestment at the discount rate as the NPV method. A profitability index of 1 indicates break even. Any value lower than one would indicate that the project's PV is less than the initial investment. As the value of the profitability index increases, so does the financial attractiveness of the proposed project.
IRR Reinvestment Assumption
As an investment decision tool, the calculated IRR should not be used to rate mutually exclusive projects but only to decide whether a single project is worth the investment. In cases where one project has a higher initial investment than a second mutually exclusive project, the first project may have a lower IRR (expected return) but a higher NPV (increase in shareholders' wealth) and, thus, should be accepted over the second project (assuming no capital constraints).
IRR assumes reinvestment of interim cash flows in projects with equal rates of return (the reinvestment can be the same or a different project). Therefore, IRR overstates the annual equivalent rate of return for a project with interim cash flows, which are reinvested at a rate lower than the calculated IRR. This presents a problem, especially for high IRR projects, since there is frequently no other project available in the interim that can earn the same rate of return as the first project.
When the calculated IRR is higher than the true reinvestment rate for interim cash flows, the measure will overestimate–sometimes very significantly–the annual equivalent return from the project. This makes IRR a suitable (and popular) choice for analyzing venture capital and other private equity investments, as these strategies usually require several cash investments throughout the project but only see one cash outflow at the end of the project (e.g., via IPO or M&A).
When a project has multiple IRRs, it may be more convenient to compute the project's IRR with the benefits reinvested. Accordingly, MIRR is used, which has an assumed reinvestment rate, usually equal to the project's cost of capital.
Calculation of the MIRR MIRR is calculated as follows:
\( MIRR = {n}\sqrt{\dfrac{\text{FV (positive cash flows, reinvestment rate}}{\text{- PV (negative cash flows, finance rate}}} - 1 \)
Key Points
- If trying to decide between alternative investments in order to maximize the value of the firm, the reinvestment rate would be a better choice.
- NPV and PI assume reinvestment at the discount rate.
- IRR assumes reinvestment at the internal rate of return.
Term
-
Weighted Average Cost of Capital (WACC) – is the rate that a company is expected to pay on average to all its security holders to finance its assets.
Example
- At the end of the first quarter, the investor had capital of 1,010.00, which then earned 10.00 during the second quarter. The extra dime was interest on his additional $10 investment.
Long-Term vs. Short-Term Financing
Long-term financing is generally for assets and projects, and short-term financing is typically for continuing operations. Achieving corporate finance goals requires appropriate financing of any corporate investment. The sources of financing are, generically, capital that is self-generated by the firm and capital from external funders obtained by issuing new debt and equity.
Management
must attempt to match the long-term or short-term financing mix to the
assets being financed as closely as possible in terms of both timing
and cash flows.

Financing to manage a business often requires long-term and short-term financing.
Long-Term Financing
Businesses need long-term financing to acquire new equipment, R&D, cash flow enhancement, and company expansion. Major methods for long-term financing are as follows:
Equity Financing
This includes preferred and common stocks and is less risky with respect to cash flow commitments. However, it does result in a dilution of share ownership, control, and earnings. The cost of equity is also typically higher than the cost of debt – which is, additionally, a deductible expense – so equity financing may result in an increased hurdle rate that may offset any reduction in cash flow risk.
Corporate Bond
Corporations issue corporate bonds to raise money effectively to expand their business. The term is usually applied to longer-term debt instruments, generally with a maturity date falling at least a year after their issue date.
Some corporate bonds have an embedded call option that allows the issuer to redeem the debt before its maturity date. Other bonds, known as convertible bonds, allow investors to convert the bond into equity.
Capital Notes
Capital notes are a form of convertible security exercisable into shares. They are equity vehicles. Capital notes are similar to warrants, except that they often do not have an expiration date or an exercise price (hence, the entire consideration the company expects to receive for its future issue of shares is paid when the capital note is issued). Many times, capital notes are issued in connection with a debt-for-equity swap restructuring: instead of issuing the shares (that replace debt) in the present, the company gives creditors convertible securities – capital notes – so the dilution will occur later.
Short-Term Financing
Short-term financing can be used for up to a year to help corporations increase inventory orders, payrolls, and daily supplies. Short-term financing includes the following financial instruments:
Commercial Paper
This is an unsecured promissory note with a fixed maturity of 1 to 364 days in the global money market. It is issued by large corporations to get financing to meet short-term debt obligations. It is only backed by an issuing bank or corporation's promise to pay the face amount on the maturity date specified on the note. Since it is not backed by collateral, only firms with excellent credit ratings from a recognized rating agency can sell their commercial paper at a reasonable price.
Asset-backed commercial paper (ABCP) is a form of commercial paper that is collateralized by other financial assets. ABCP is typically a short-term instrument that matures between 1 and 180 days from issuance and is typically issued by a bank or other financial institution.
Promissory Note
This is a negotiable instrument wherein one party (the maker or issuer) makes an unconditional promise in writing to pay a determinate sum of money to the other (the payee), either at a fixed or determinable future time or on demand of the payee, under specific terms.
Asset-Based Loan
This type of loan, often short-term, is secured by a company's assets. Real estate, accounts receivable (A/R), inventory, and equipment are typical assets used to back up the loan. The loan may be backed by a single category of assets or a combination of assets (for instance, a combination of A/R and equipment).
Repurchase Agreements
These are short-term loans (normally for less than two weeks and frequently for just one day) arranged by selling securities to an investor with an agreement to repurchase them at a fixed price on a fixed date.
Letter of Credit
This is a document that a financial institution or similar party issues to a seller of goods or services, which provides that the issuer will pay the seller for goods or services the seller delivers to a third-party buyer. The issuer then seeks reimbursement from the buyer or the buyer's bank. The document serves essentially as a guarantee to the seller that it will be paid by the issuer of the letter of credit, regardless of whether the buyer ultimately fails to pay.
Key Points
- Management must match long-term financing or short-term financing mix to the assets being financed in terms of both timing and cash flow.
- Long-term financing includes equity issued, Corporate bond, Capital notes and so on.
- Short-term financing includes Commercial papers, Promissory notes, Asset-based loans, Repurchase agreements, letters of credit and so on.
Terms
- Swap – in finance, a swap is a derivative in which counterparties exchange cash flows of one party's financial instrument for those of the other party's financial instrument.
- Call Option – a call option, often simply labeled a "call", is a financial contract between two parties, the buyer and the seller of this type of option. [1] The buyer of the call option has the right, but not the obligation to buy an agreed quantity of a particular commodity or financial instrument (the underlying) from the seller of the option at a certain time (the expiration date) for a certain price (the strike price)
- Accounts Receivable – also known as Debtors, is money owed to a business by its clients (customers) and shown on its balance sheet as an asset.
