The debit and credit rules are: all assets increase by debit side (left) and decrease by credit side (right),
liabilities increase by credit side (right) and decrease by debit side (left), and equity accounts increase by
credit side (right) and decrease by debit side (left). The equity subdivisions or categories will use the debit
and credit rules to present the effect on the organization’s equity. The equity subdivision rules are:
1. Revenues increase the organization’s equity in the business. Revenue accounts increase by credit
and decrease by debit (same as the equity).
2. The expenses decrease the organization’s equity. Therefore, all expense accounts will increase by
Key Concepts: normal balance of an account, chart of accounts, compound entry, double-entry
bookkeeping
Lecture Outline:
1) Refer to Table 2.1 for the rules of debit and credit using T accounts affecting the accounting equation.
a) For assets increases are on the debit (left) side.
b) For liabilities increases are on the credit (right) side.
c) For capital increases are on the credit (right) side.
d) For revenue increases are on the credit side which is the same as for capital.
e) For withdrawals and expenses increases are on the debit side which is the opposite of how capital
increases are.
f) A normal balance of an account is the side that increases by the rules of debit and credit.
g) The accounting equation balance must be maintained when transactions occur.
2) A chart of accounts is a numbered list of all of a business’s accounts.
a) Assets use 100s (as an example).
b) Liabilities use 200s.
c) Owner’s Equity uses 300s.
d) Revenues use 400s.
e) Expenses use 500s.
3) Transaction analysis: five steps:
a) Determine which accounts are affected.
b) Determine which categories the accounts belong to: assets, liabilities, capital, withdrawals, revenue,
or expenses.
c) Determine whether the accounts increase or decrease.
d) What do the rules of debit and credit say?
e) What does the T account look like?
4) Compound entry is a transaction involving more than one debit or credit.
5) Double-entry bookkeeping refers to an accounting system in which the recording of each transaction
affects two or more accounts, and the total of the debits is equal to the total of credits.
Teaching Tips/Strategy: Use the “Success Coach” LU 2-2 (end of the chapter) to review the debit and
credit rules. After reviewing the concepts, complete the Concept Checks #2 and #3 to check the debit and
credit rules. Exercises 2A-1, 2A-2, 2A-3, and 2A-4 are excellent classroom practice to reinforce the
objective #2 concepts.
Use the “Ten–Minute Quiz” questions #1 – #5 to reinforce the Learning Objective #2.
