This chapter explains the rules regarding debits and credits. Debits and credit increase and decrease certain accounts. Spend some time learning the rules of debits and credits, since they are the foundation of accounting principles. Posting a debit where a credit should be, or vice versa, will cause you to be out of balance. You will then have to re-trace all of your postings to uncover your error, which would be very frustrating and time-consuming. Since accounting is the "language of business", it is very important that you understand the building blocks of the language. Even if you hire a CPA to do your books, you need an understanding of what drives your results so that you can manage accordingly, and avoid becoming a victim of fraud.
The journal
In explaining the rules of debit and credit, we recorded transactions directly in the accounts. Each
ledger (general ledger) account shows only the increases and decreases in that account. Thus, all the
effects of a single business transaction would not appear in any one account. For example, the Cash
account contains only data on changes in cash and does not show how the cash was generated or how it
was spent. To have a permanent record of an entire transaction, the accountant uses a book or record
known as a journal.
A journal is a chronological (arranged in order of time) record of business transactions. A journal
entry is the recording of a business transaction in the journal. A journal entry shows all the effects of a
business transaction as expressed in debit(s) and credit(s) and may include an explanation of the
transaction. A transaction is entered in a journal before it is entered in ledger accounts. Because each
transaction is initially recorded in a journal rather than directly in the ledger, a journal is called a book
of original entry.
A business usually has more than one journal. Chapter 4 briefly describes several special journals.
In this chapter, we use the basic form of journal, the general journal. As shown in Exhibit 8, a general
journal contains the following columns:
Exhibit 7: Steps in the accounting cycle
Exhibit 8: Journal entry
MICROTRAIN COMPANY General Journal | ||||||||||||||||
Date | Account Titles and Explanation | Post. Ref. | Debit | Credit | ||||||||||||
2010 Nov. | 28 | Cash (+A) | 100 | 5 | 0 | 0 | 0 | 0 | ||||||||
Capital Stock (+SE) | 300 | 5 | 0 | 0 | 0 | 0 | ||||||||||
Stockholders invested $50,000 cash in business. |
Date column. The first column on each journal page is for the date. For the first journal
entry on a page, this column contains the year, month, and day (number). For all other journal
entries on a page, this column contains only the day of the month, until the month changes.
Account titles and explanation column. The first line of an entry shows the account
debited. The second line shows the account credited. Notice that we indent the credit account
title to the right. For instance, in Exhibit 8 we show the debit to the Cash account and then the
credit to the Capital Stock account. Any necessary explanation of a transaction appears on the
line(s) below the credit entry and is indented halfway between the accounts debited and
credited. A journal entry explanation should be concise and yet complete enough to describe
fully the transaction and prove the entry's accuracy. When a journal entry is self-explanatory,
we omit the explanation.
Posting reference column. This column shows the account number of the debited or
credited account. For instance, in Exhibit 8, the number 100 in the first entry means that the
Cash account number is 100. No number appears in this column until the information has
been posted to the appropriate ledger account. We discuss posting later in the chapter.
Debit column. In the debit column, the amount of the debit is on the same line as the title
of the account debited.
Credit column. In the credit column, the amount of the credit is on the same line as the
title of the account credited.
An account perspective: Uses of technology
Preparing journal entries in a computerized system is different than in a manual
system. The computer normally asks for the number of the account to be debited. After
you type the account number, the computer shows the account title in its proper
position. The cursor then moves to the debit column and waits for you to enter the
amount of the debit. Then it asks if there are more debits. If not, the computer
prompts you for the account number of the credit. After you type the account number,
the computer supplies the account name of the credit and enters the same amount
debited as the credit. When there is more than one credit, you can override the
amount and enter the correct amount. Then you would enter the other credit in the
same way. If your debits and credits are not equal, the computer warns you and makes
you correct the error. You can supply an explanation for the entry from a standard list
or type it in. As you enter the journal entries, the computer automatically posts them
to the ledger accounts. At any time, you can have the computer print a trial balance.
A summary of the functions and advantages of using a journal follows:
The journal -
- Records transactions in chronological order.
- Shows the analysis of each transaction in debits and credits.
- Supplies an explanation of each transaction when necessary.
- Serves as a source for future reference to accounting transactions.
- Eliminates the need for lengthy explanations from the accounts.
- Makes possible posting to the ledger at convenient times.
- Assists in maintaining the ledger in balance because the debit(s) must always equal the credit(s)
in each journal entry.
- Aids in tracing errors when the ledger is not in balance.
