7 Important Rules in Double Entry Accounting

How to Debit and Credit Assets, Liabilities and Owner's Equity

Jun 1, 2009 Miranda Miller

Double entry accounting requires that each transaction is properly recorded in two accounts. The sum of all credits must equal the sum of all debits.

In double entry accounting, a company's assets are equal to its liabilities plus owner's equity. This is known as the accounting equation.

Accounting Equation Quick Reference

Assets = Liabilities + Owner's Equity

Each action on one type of account must have an equal effect in the opposite column. For example, paying the monthly mortgage payment decreases assets. The equal effect on the opposite side is that it reduces the amount owed to the lender, subsequently decreasing the company's liabilities. Both of these effects are recorded and help the credits and debits equal out further into the accounting cycle.

It can be tricky to remember how to record transactions. It would seem logical to record an increase in assets, such as a cash payment, in the credit column. However, this is not so. Use the following three rules for quick reference when recording transactions in double entry accounting:

Assets

• Debit for increases, record on the left
• Credit for increases, record on the right

Liabilities

• Debit for decreases, record on the left
• Credit for increases, record on the right

Owner's Equity

• Debit for decreases, record on the left
• Credit for increases, record on the right

Recording Transactions in Owner's Capital, Revenues, Expenses & Owner's Withdrawals

These four types of transactions all affect owner's equity. Increases in revenue or owner's capital increase the owner's equity. Increases in expenses or owner's withdrawals accounts cause owner's equity to decrease. These four rules are a quick reference to posting transactions in these types of accounts:

Owner's Capital

• Debit for decreases, record on the left
• Credit for increases, record on the right

Revenues

• Debit for decreases, record on the left
• Credit for increases, record on the right

Expenses

• Debit for increases, record on the left
• Credit for decreases, record on the right

Owner's Withdrawals

• Debit for increases, record on the left
• Credit for decreases, record on the right

Why Accounting Knowledge is Important

Understanding how and why accounting methods work helps business owners make good decisions, verify their records, and immediately spot problems or mistakes. Even when using computerized bookkeeping software, business owners and manager must understand the effects of everyday decisions and transactions on the company's finances.
