Product Return Rate Calculator
Calculate returned units as a percentage of units sold from the same sales cohort. Review product quality and fulfillment issues.
What does this calculator measure?
Product return rate measures the percentage of units sold that customers return. Use returns linked to the same group of sales so delayed returns from older sales do not distort the denominator.

Start managing inventoryFormula and worked example
Product return rate (%) = Returned units ÷ Units sold in the same cohort × 100
For 500 units sold and 25 of those units returned, product return rate is 25 ÷ 500 × 100 = 5%. There are 475 units not returned at the time of measurement.
How to use the calculator
- Choose the product, category or business and the period you want to review.
- Enter the figures described beside each field using consistent units.
- Review the result alongside the assumptions below before changing purchasing or stock plans.
How to interpret your result
Compare products after similar return windows have elapsed. A recent cohort may appear to have a low rate because returns have not yet arrived. Returned units are not automatically sellable stock: inspect them before putting them back into available inventory. This metric measures units, not refunded value or the percentage of orders with a return.

Should I subtract returns from units sold?
No. Use the original units sold as the denominator and returned units as the numerator. Net units sold would inflate the return rate.
What if returns exceed sales this month?
Monthly returns may relate to earlier sales. Use a matched sales cohort instead of dividing unrelated calendar-period totals.
Does a returned unit count as available inventory?
Only if it passes your inspection and restocking process. Damaged or unsellable returns should not be added to usable stock.
