Contra Accounts: Types, Examples, and How They Work
Definition
A contra account is an account paired with a related account that offsets its balance. Contra accounts have a normal balance opposite to the account they are paired with — for example, Accumulated Depreciation (credit balance) is a contra-asset paired with Equipment (debit balance).
How It Works
Contra accounts are used to reduce the balance of their related account without directly changing it. This preserves the original account balance for reference while showing the net value. For example, Equipment might have a balance of $100,000 (its original cost) and Accumulated Depreciation might have a balance of $40,000. The net book value is $60,000, but both the cost and the depreciation are visible on the balance sheet. The four main types are: contra-asset (Accumulated Depreciation, Allowance for Doubtful Accounts), contra-liability (Discount on Bonds Payable), contra-revenue (Sales Returns and Allowances, Sales Discounts), and contra-equity (Treasury Stock).
Example
A company owns a delivery truck purchased for $30,000. After 3 years of straight-line depreciation ($6,000/year), Accumulated Depreciation is $18,000. On the balance sheet: Delivery Truck $30,000, Less: Accumulated Depreciation ($18,000), Net Book Value $12,000. The original cost is preserved while the current value is clearly shown.
Journal Entry Example
Record annual depreciation on the delivery truck.
| Account | Debit | Credit |
|---|---|---|
| Depreciation Expense | $6,000 | |
| Accumulated Depreciation | $6,000 |
Common Misconceptions
- ✗Contra accounts are unnecessary — you could just reduce the main account directly. But contra accounts preserve important information. Knowing both the original cost of equipment and its accumulated depreciation is more useful than only seeing the net value.
- ✗All contra accounts have credit balances — contra accounts have the OPPOSITE balance of their paired account. Contra-assets have credit balances, but contra-liabilities have debit balances, and contra-revenue has debit balances.
- ✗Accumulated Depreciation is an expense — it's a contra-asset on the balance sheet. Depreciation Expense is the income statement account. They are related but different: the expense is the periodic cost, while accumulated depreciation is the cumulative total.

Common questions about Contra Accounts
The most common are: Accumulated Depreciation (contra-asset), Allowance for Doubtful Accounts (contra-asset), Sales Returns and Allowances (contra-revenue), Sales Discounts (contra-revenue), and Treasury Stock (contra-equity). Discount on Bonds Payable is a contra-liability.
It depends on the type. Contra-asset and contra-liability accounts appear on the balance sheet. Contra-revenue accounts appear on the income statement. Contra-equity (Treasury Stock) appears in the stockholders' equity section of the balance sheet.
This rarely happens and usually indicates an error. For example, Accumulated Depreciation should never exceed the asset's original cost (you can't depreciate more than the total cost). If Allowance for Doubtful Accounts exceeds Accounts Receivable, the AR subsidiary ledger likely needs review.
