What is the Allowance for Doubtful Accounts?
Not every customer who buys on credit will pay in full. The allowance for doubtful accounts is a contra-asset account that estimates how much of accounts receivable a company expects it will never collect.
The allowance for doubtful accounts is a contra-asset that reduces accounts receivable to its net realizable value. It is estimated as a percentage of receivables (or sales) and recorded before specific customers actually default, following the matching principle.
- •Estimates bad debt in advance
- •Matches expense to the period of sale
- •Uses a contra-asset account
- •Required under US GAAP
- •Records bad debt only when confirmed uncollectible
- •Violates the matching principle
- •No estimate or contra-asset used
- •Allowed only for immaterial amounts / tax reporting

Step-by-step worked examples
A company has $150,000 in accounts receivable and estimates 4% will be uncollectible. What is the allowance for doubtful accounts?
Allowance = AR × % = 150,000 × 0.04 Allowance = $6,000
Using the aging method, a company classifies $80,000 as current (2% uncollectible) and $20,000 as over 90 days (25% uncollectible). Find the total allowance.
Current: 80,000 × 0.02 = $1,600 Over 90 days: 20,000 × 0.25 = $5,000 Total allowance = 1,600 + 5,000 = $6,600
The allowance account has an existing credit balance of $1,000. The company estimates it now needs a $6,000 allowance. What adjusting entry is recorded?
Required balance = $6,000 Existing credit balance = $1,000 Adjustment needed = 6,000 − 1,000 = $5,000 Entry: Debit Bad Debt Expense $5,000, Credit Allowance for Doubtful Accounts $5,000

Common mistakes
Believing the allowance amount is subtracted from cash. — Correct: It is subtracted from Accounts Receivable, not cash — it never touches the cash account.
Recording bad debt expense again for the full new allowance balance every period. — Correct: Only the incremental adjustment (needed balance minus existing balance) is expensed.
Thinking a write-off reduces net income at the time it happens. — Correct: The expense was already recognized when the allowance was estimated; the write-off itself has no income statement effect.
Confusing the allowance method with the direct write-off method. — Correct: GAAP requires the allowance (estimation) method for material amounts; direct write-off is not GAAP-compliant.
FAQ
What is the allowance for doubtful accounts?
It is a contra-asset account that estimates the portion of accounts receivable a company does not expect to collect.
What is the formula for the allowance for doubtful accounts?
Allowance = Accounts Receivable × Estimated Uncollectible Percentage, often refined using an aging schedule.
What are examples of estimating the allowance?
Percentage-of-sales estimates a flat rate on credit sales; aging of receivables applies higher rates to older, riskier balances.
How do you calculate the allowance for doubtful accounts?
Multiply total receivables (or each aging bucket) by the estimated uncollectible rate, then sum the results.
