A short collection period means cash comes in quickly. If it is much longer than your credit terms (for example 30 days), customers are paying late and your working capital is tied up in receivables.
How to use the Average Collection Period Calculator
- Average accounts receivable
- Annual credit sales
- Days in the year
- Credit terms
Results update as you type, and every field accepts the units shown in its menu.
How it works
Enter average accounts receivable, annual credit sales and the credit terms you offer.
Tips
- Use figures for the same period (a month, a quarter or a year) for every input so ratios compare like with like.
- Track the metric over time – the trend usually tells you more than a single value.
- Compare your result with industry benchmarks, which vary a lot between sectors.
- Treat the result as a starting point for a decision, then check the assumptions behind each input.
Common mistakes to avoid
- Mixing monthly and yearly numbers in the same calculation.
- Using revenue where the formula needs profit (or the other way round).
- Forgetting hidden costs such as taxes, fees, overheads or your own time.
