Example Data Table
This sample uses the percent of receivables approach and shows how the adjustment is derived from an unadjusted allowance balance.
| Method | Accounts Receivable | Opening Allowance | Write-offs | Recoveries | Rate | Pre-adjustment Allowance | Required Ending Allowance | Adjustment | Net Receivable |
|---|---|---|---|---|---|---|---|---|---|
| Percent of Receivables | $150,000.00 | $3,000.00 Credit | $1,800.00 | $200.00 | 4.00% | $1,400.00 Credit | $6,000.00 | $4,600.00 | $144,000.00 |
Formula Used
Allowance Roll-forward
Opening signed allowance = credit balance as positive, debit balance as negative.
Pre-adjustment allowance = opening allowance − write-offs + recoveries.
Ending allowance = pre-adjustment allowance + current period adjustment.
Method Formulas
Percent of receivables = accounts receivable × expected loss rate.
Aging = sum of each bucket amount × bucket loss rate.
Percent of sales = credit sales × bad debt rate.
Adjustment Logic
Balance sheet approaches use:
Adjustment = required ending allowance − pre-adjustment allowance.
Income statement approach uses:
Adjustment = credit sales × bad debt rate.
Net accounts receivable = gross accounts receivable − ending allowance.

Frequently Asked Questions
1) What does this calculator estimate?
It estimates the bad debt adjustment needed to align the allowance for doubtful accounts with your chosen method. It also shows the ending allowance, net receivable, and a suggested journal entry.
2) Which method should I choose?
Use percent of sales when policy focuses on matching expense to period revenue. Use percent of receivables or aging when policy focuses on the desired ending allowance balance.
3) Why can the adjustment be negative?
A negative adjustment means the existing allowance is already higher than the amount required by your current estimate. That situation creates a reversal entry instead of additional bad debt expense.
4) Do write-offs affect current expense directly?
Normally, no. A write-off reduces accounts receivable and the allowance account. Current expense is recognized through the adjusting entry, not when a specific customer balance is written off.
5) What if the allowance has a debit balance?
A debit allowance balance usually means write-offs exceeded the existing credit allowance. The calculator handles that by treating the opening balance as negative before computing the needed adjustment.
6) Should aging bucket totals equal receivables?
Yes, ideally. The aging method is strongest when all receivables are assigned to buckets and the total equals gross accounts receivable. The calculator warns you when those totals differ materially.
7) What does net receivable show?
Net receivable shows the estimated collectible amount after subtracting the ending allowance from gross accounts receivable. It is often called net realizable value in reporting discussions.
8) Can I use this monthly and at year-end?
Yes. The same structure works for monthly closes, quarter-end reporting, and annual adjustments. Just use period-appropriate balances, rates, and aging data that match your close process.
