Estimating losses before they're confirmed
Rather than waiting until specific customer accounts are confirmed uncollectible, this method estimates expected bad debt upfront as a percentage of total credit sales, based on a business's own historical loss experience.
Worked example
For $500,000 in credit sales with a 2% historical bad debt rate:
Allowance = 500000 x (2/100) = 10,000.0
Recording this allowance lets a business recognize expected credit losses in the same accounting period as the related sales were made, matching the timing principle central to accrual-basis accounting rather than waiting for losses to materialize later.
