Allowance for Doubtful Accounts (ADA)

Accounts Receivable Dictionary

What is Allowance for Doubtful Accounts?

The Allowance for Doubtful Accounts is an accounting technique that estimates the portion of a company's accounts receivable which may ultimately be uncollectible. It is an application of the conservatism principle in accounting.

Importance in Accounts Receivable

ADA is crucial to the management of accounts receivable because it allows companies to project potential credit losses and adjust their financial reporting accordingly. It helps maintain an accurate representation of a company's financial health by reflecting a more realistic picture of the net receivables that will likely be converted into cash.

In Practice

In a typical business setting, the accounting or finance department calculates the ADA. They might use methods like the percentage of sales method (calculating ADA as a percentage of total net sales), or the accounts receivable aging method (estimating ADA based on the length of time receivables have been outstanding).


Imagine a company that has $100,000 in accounts receivable. Based on historical data, the company estimates that 5% of its receivables are usually uncollectible. Therefore, the company would record $5,000 (5% of $100,000) as an Allowance for Doubtful Accounts. On its balance sheet, this would be subtracted from the total accounts receivable to present a more accurate view of its receivables that are expected to be collected.
