Allowance for Doubtful Accounts: Setup, Calculation & Entries
Allowance for Doubtful Accounts: Setup, Calculation & Entries
Key Takeaways
- The allowance for doubtful accounts is a contra-asset account that reduces gross accounts receivable to its net realizable value on the balance sheet.
- It carries a normal credit balance and is never an expense account itself — the related expense is Bad Debt Expense.
- XYZ Corp estimates a $10,000 allowance on $120,000 in receivables using an aging schedule.
- The balance sheet shows: A/R $120,000 − Allowance $10,000 = Net A/R $110,000.
- At year-end, an adjusting entry brings the allowance to the required target balance — taking into account any existing balance.
The allowance for doubtful accounts is a contra-asset account on the balance sheet that represents the estimated portion of accounts receivable that a business does not expect to collect. It is subtracted from gross accounts receivable to show the net realizable value — the realistic cash amount the business can expect to receive.
Understanding how to set up, calculate, and adjust this account is essential for accurate financial reporting and is a core topic in GAAP-based accounting and CPA exam preparation.
What Is the Allowance for Doubtful Accounts?
The allowance for doubtful accounts (also called allowance for uncollectible accounts or allowance for bad debts) is the cumulative estimate of receivables that are unlikely to be collected. It accumulates period-end bad debt estimates and absorbs actual write-offs as they occur throughout the year.
It is paired with the Bad Debt Expense account: bad debt expense hits the income statement; the allowance for doubtful accounts lives on the balance sheet as a running reserve against accounts receivable.
- Bad Debt Expense — Income statement; the periodic charge for estimated uncollectibles
- Allowance for Doubtful Accounts — Balance sheet (contra asset); the cumulative reserve against A/R
Why It's a Contra-Asset
A contra-asset is an account that has a normal credit balance and is linked to an asset account (in this case, Accounts Receivable). It reduces the carrying value of that asset without reducing the asset itself.
This distinction matters: the gross accounts receivable balance stays intact (showing what was billed), while the allowance account sits alongside it on the balance sheet, clearly disclosing the estimated collectible amount and the expected loss.
| Account | Type | Normal Balance | Location |
|---|---|---|---|
| Accounts Receivable | Asset | Debit | Balance Sheet (Current Assets) |
| Allowance for Doubtful Accounts | Contra-Asset | Credit | Balance Sheet (reduces A/R) |
| Bad Debt Expense | Expense | Debit | Income Statement |
How to Calculate the Allowance for Doubtful Accounts
There are two main calculation methods. Both are used under the allowance method.
Method 1: Percentage of Sales
Apply a bad debt rate to credit sales for the period. The result is the amount to add to the allowance, not the target ending balance.
Bad Debt Expense (and addition to Allowance) = $500,000 × 2% = $10,000Method 2: Aging of Receivables
Analyse each age bracket of outstanding receivables and apply bracket-specific default rates. The result is the required ending balance of the allowance account — the adjusting entry is only the difference needed.
Aging Schedule Example — XYZ Corp
XYZ Corp has $120,000 in accounts receivable at December 31. Management applies the following default rates by age:
| Age Bracket | Receivable Balance | Default Rate | Allowance Required |
|---|---|---|---|
| 0–30 days (current) | $60,000 | 1% | $600 |
| 31–60 days | $30,000 | 3% | $900 |
| 61–90 days | $15,000 | 10% | $1,500 |
| 91–120 days | $10,000 | 25% | $2,500 |
| 120+ days (including Customer ABC $3,000) | $5,000 | 90% | $4,500 |
| Total | $120,000 | $10,000 |
Target ending balance of Allowance for Doubtful Accounts: $10,000
Note: Customer ABC's $3,000 (180+ days overdue) is included in the 120+ bracket, driving that bucket's high $4,500 estimate. This account will later be specifically written off. See: Bad Debt Expense Journal Entry.
Journal Entries
Entry 1: Year-End Estimate (No Prior Balance)
Assuming no opening allowance balance (first year):
Dr. Bad Debt Expense $10,000 Cr. Allowance for Doubtful Accounts $10,000 (To record year-end estimate based on aging schedule)
Entry 2: Year-End Estimate (With Existing Balance)
If the allowance already has a $2,000 credit balance from prior write-off reversals, only $8,000 more is needed:
Dr. Bad Debt Expense $8,000 Cr. Allowance for Doubtful Accounts $8,000 (Adjusting entry: $10,000 target − $2,000 existing balance)
Entry 3: Write-Off of Specific Account (Customer ABC — $3,000)
Dr. Allowance for Doubtful Accounts $3,000 Cr. Accounts Receivable – Customer ABC $3,000 (Write-off of 180+ day overdue account — no income statement impact)

Balance Sheet Presentation
The allowance for doubtful accounts appears in the current assets section of the balance sheet, directly below or alongside accounts receivable:
| XYZ Corp — Partial Balance Sheet (December 31) | |
|---|---|
| Current Assets | Amount |
| Cash | $XX,XXX |
| Accounts Receivable | $120,000 |
| Less: Allowance for Doubtful Accounts | ($10,000) |
| Net Accounts Receivable | $110,000 |
| Inventory | $XX,XXX |
This presentation format is standard under GAAP. For context on how this fits into the broader financial statement framework, see: What Is a Financial Statement.

Year-End Adjusting Entries
The allowance account must be adjusted at every year-end (or quarter-end for quarterly reporters). The adjustment depends on the estimation method used.
Under the Percentage of Sales Method
The bad debt expense calculated is added to the allowance, regardless of the existing balance. This means the allowance balance can grow or shrink unpredictably over time if write-offs don't align with estimates.
Under the Aging Method
The aging method targets a specific ending balance. The adjusting entry is only what's needed to reach that target.
| Scenario | Target Balance | Existing Balance | Adjusting Entry |
|---|---|---|---|
| Allowance needs topping up | $10,000 Cr | $2,000 Cr | Dr. Bad Debt Expense $8,000 / Cr. Allowance $8,000 |
| Allowance already too high | $10,000 Cr | $12,000 Cr | Dr. Allowance $2,000 / Cr. Bad Debt Expense $2,000 |
| First year (no prior balance) | $10,000 Cr | $0 | Dr. Bad Debt Expense $10,000 / Cr. Allowance $10,000 |

Frequently Asked Questions
What is the allowance for doubtful accounts?
The allowance for doubtful accounts is a contra-asset account on the balance sheet that represents the estimated portion of accounts receivable that will not be collected. It carries a credit balance and is subtracted from gross accounts receivable to show the net realizable value of receivables.
Is the allowance for doubtful accounts a debit or credit?
The allowance for doubtful accounts carries a normal credit balance. It is increased (credited) when bad debt expense is estimated at year-end, and decreased (debited) when specific accounts are written off.
What is the difference between allowance for doubtful accounts and bad debt expense?
Bad Debt Expense is an income statement account — it captures the periodic cost of estimated uncollectibles. The Allowance for Doubtful Accounts is a balance sheet account — it is the cumulative reserve that offsets accounts receivable. They are linked: recording bad debt expense simultaneously increases the allowance.
How does the allowance for doubtful accounts appear on the balance sheet?
It appears in the current assets section as a deduction from accounts receivable. The presentation is: Accounts Receivable $120,000 / Less: Allowance for Doubtful Accounts ($10,000) / Net Accounts Receivable $110,000. This format is required under GAAP.
What happens to the allowance when a bad debt is written off?
When a specific account is written off, the allowance for doubtful accounts is debited and accounts receivable is credited. This reduces both accounts by the same amount, so net accounts receivable does not change. The income statement is not affected at the time of the write-off.
Can the allowance for doubtful accounts have a debit balance?
Temporarily, yes. If actual write-offs during the year exceed the balance in the allowance account, it can develop a debit balance before the year-end adjusting entry. This is corrected by the year-end estimate entry, which restores the account to its proper credit balance.
Is allowance for doubtful accounts the same as allowance for uncollectible accounts?
Yes — these are interchangeable names for the same account. Other common names include "provision for bad debts" (more common in IFRS environments) and "allowance for bad debts". All refer to the contra-asset reserve maintained against accounts receivable.
