This calculator estimates the physical-product return rate by comparing returned units with units sold. It is designed for merchants who need a consistent view of how frequently products come back after purchase and how that pattern changes by product, channel, or period.
Return rate can highlight sizing problems, misleading descriptions, quality issues, packaging damage, or fulfillment errors. Align the sales and return windows carefully because returns often occur after the original sale date.
1. Enter units returned. Use values from the same product, SKU group, and reporting period.
2. Enter units sold. Use values from the same product, SKU group, and reporting period.
3. Review the result. The calculator updates automatically as inputs change. Use Reset to restore the example values.
The displayed value summarizes unit return rate using the inputs entered above.
Use consistent units and matching reporting periods. Results are estimates for planning and review.
Given: 84 returned units from a cohort of 2,400 units sold.
Calculation: 84 ÷ 2,400 × 100 = 3.50%.
Result: The cohort has a 3.50% unit return rate.
Use units when customers may buy several items in one order. Order-based return rates answer a different question.
Count the original unit as returned if it came back, then record the replacement according to your inventory policy.
A cohort approach—tracking returns from a defined sales period—is usually clearest.
No. Cancellations that never shipped should be excluded.
A return tracks goods coming back; a refund tracks money issued. They can differ.
