aging of receivables

Think about money friends owe you. A debt from last week barely worries you; a debt from a year ago, where they've stopped answering your calls, feels nearly hopeless. The older a debt gets, the less likely you are to ever see it. Aging of receivables is a tool that sorts a company's unpaid customer balances by how long they've been outstanding, on exactly this intuition.

An aging schedule groups every customer balance into time buckets — for instance, not yet due, 1 to 30 days past due, 31 to 60 days, 61 to 90 days, and over 90 days. The company then applies an estimated loss rate to each bucket, with higher rates for older buckets, to estimate the total allowance for doubtful accounts. Suppose a firm has 80,000 current (estimated 1% bad), 15,000 thirty-to-sixty days late (10% bad), and 5,000 over ninety days (50% bad). The estimated uncollectible total is 800 + 1,500 + 2,500 = 4,800, which becomes the target balance for the allowance. This is the most accurate way to apply the allowance method, because it ties the estimate directly to the real condition of each receivable.

Beyond setting the allowance, an aging report is one of the most useful management tools in the whole business: it spotlights slow-paying customers, flags accounts heading toward default, and guides collection efforts. A key subtlety: under the aging approach, the calculated number is the desired ending balance of the allowance, so the bad debt expense you record is the amount needed to move the allowance from its current balance to that target — not the full computed figure.
