Allowance for Bad Debt: Definition and Overview An allowance for bad debt (also called allowance for doubtful accounts) is a contra-asset valuation account used to estimate the portion of a company’s accounts receivable that will not be collected. It reduces the gross receivable balance to a realistic net realizable value and matches expected credit losses to the same period as the related sales. Why it Matters
* The face value of accounts receivable overstates collectible cash; some customers will not pay.
* Recording an allowance ensures financial statements present a more accurate asset value and matches expenses (bad debt expense) with the revenues that generated the receivables.
* Accurate allowances are important for users of financial statements and for regulatory compliance.
Common Estimation Methods There are two primary approaches to estimating the allowance: Explore More Resources

  1. Sales (Income Statement) Method
  2. Estimates bad debts as a percentage of credit sales for the period.
  3. Simple and suited for companies with stable historical loss rates.
  4. Example: $1,000,000 in credit sales Γ— 1.5% uncollectible = $15,000 bad debt expense.
  5. Accounts Receivable (Balance Sheet) / Aging Method Explore More Resources




  6. Evaluates receivables by age; older receivables receive higher estimated loss rates.
  7. Produces a target allowance balance based on the composition of outstanding receivables.
  8. Example aging schedule: 
     * Current receivables β€” 1% uncollectible
     * 30 days past due β€” 10% uncollectible
     * 90+ days past due β€” 50% uncollectible
  9. More accurate for firms with diverse receivable aging profiles.

Accounting Treatment and Journal Entries
* To record estimated bad debts (using whichever method is chosen):
* Debit Bad Debt Expense
* Credit Allowance for Doubtful Accounts (contra-asset)
* When a specific receivable is confirmed uncollectible (write-off): Explore More Resources

  * Debit Allowance for Doubtful Accounts
  * Credit Accounts Receivable

These entries leave net accounts receivable reduced and match expenses to the appropriate period. Adjustments and Defaults
* The allowance should be adjusted periodically to reflect updated estimates of uncollectible receivables.
* Example: If estimated at-risk loans are $2,000,000 and the allowance currently has a $1,000,000 balance, an adjusting entry would record $1,000,000 additional bad debt expense to bring the allowance to $2,000,000.
* When a specific loan or receivable is confirmed in default, the company writes it off against the allowance rather than recording a new expense.
GAAP Guidance and Practical Considerations
* Under GAAP, the allowance must reasonably reflect the firm’s historical collection experience and current conditions.
* Established firms typically use their own history; new businesses rely on industry averages or comparable companies until historical data accumulate.
* An accurate allowance is necessary to determine the true value of accounts receivable and present reliable financial statements.
Key Takeaways
* The allowance for bad debt is a contra-asset that adjusts accounts receivable to net realizable value.
* Two main estimation approaches are the sales method (percent of credit sales) and the aging/accounts receivable method.
* Record estimated bad debts as an expense and credit the allowance; write-offs debit the allowance and credit receivables.
* Regular adjustments and reasonable estimates are required under GAAP to reflect expected credit losses.
