What is the allowance for doubtful accounts?

It is a contra-asset account (credit balance) that reduces gross accounts receivable to the net realizable value — the amount the company actually expects to collect. It is recorded before specific bad debts are identified, in accordance with the matching principle.

What is the difference between the percentage and aging methods?

The percentage-of-receivables method applies one flat uncollectible rate to the total AR balance. The aging-of-receivables method splits AR into buckets by how long invoices have been outstanding and applies a different (usually higher) rate to older buckets, giving a more precise estimate.

What journal entry do I record?

If the required allowance exceeds the current balance, debit Bad Debt Expense and credit Allowance for Doubtful Accounts for the difference. If the current balance exceeds the required allowance, debit Allowance for Doubtful Accounts and credit Bad Debt Expense (a rare reversal).

What uncollectible rates should I use?

Rates vary by industry and customer base. Common starting points: current AR 0.5-1%, 1-30 days 2-3%, 31-60 days 5-10%, 61-90 days 15-25%, 90+ days 40-60%. Use your own historical write-off data for the most accurate estimate.

Is this the same as the direct write-off method?

No. The direct write-off method records bad debt expense only when a specific account is deemed uncollectible. GAAP requires the allowance method for companies with material AR because it better matches revenues with expenses in the same period.

Summary

Calculate your bad debt reserve using the percentage-of-receivables or aging-of-receivables method.

How it works

Choose a calculation method: percentage-of-receivables (simple) or aging-of-receivables (detailed).
For the percentage method, enter total accounts receivable and your estimated uncollectible rate.
For the aging method, enter the balance and expected loss rate for each aging bucket (current, 1-30 days, 31-60 days, 61-90 days, 90+ days).
Enter the current ADA balance (credit if existing allowance, debit if over-collected).
The calculator computes the required allowance, the adjustment needed, and the journal entry.
