What this calculator measures
Calculate item return rate and estimated retained orders.
Use consistent item- or order-level definitions. Enter values from the same reporting period and retain the source data so the result can be reproduced.
Common use cases
Use this model when the inputs describe the same decision, period and customer or product scope.
- Calculate item return rate and estimated retained orders.
- Use the result with the recorded inputs: Items sold, Items returned.
- Compare multiple scenarios before making a ecommerce decision.
Formula
Use consistent item- or order-level definitions.
Return Rate: formula, inputs and interpretation
Use consistent item- or order-level definitions.
Formula
Example input values
Worked calculation and answer
400 returned items from 5,000 sold items produce an 8% item return rate.
Variable definitions and checks
- Items sold (sold): Use a numeric value at least 0. Check its reporting period and definition before comparing it with other inputs.
- Items returned (returned): Use a numeric value at least 0. Check its reporting period and definition before comparing it with other inputs.
When the result may mislead
The calculation reflects the variables named above, not unentered taxes, platform terms, reporting delays, financing charges or external forecasts. For comparisons, keep the same units and reporting period and change one assumption at a time.
How to interpret the result
Segment by SKU, reason, channel, and cohort; also measure refund, handling, and resale loss.
Use the result as a decision aid rather than a standalone conclusion. Compare trends and scenarios using unchanged definitions.
Assumptions and limitations
- Inputs use compatible periods and definitions.
- Amounts are entered before rounding unless stated otherwise.
- The model excludes fields not shown in the calculator.
- Material accounting, tax, legal, and investment decisions require independent verification.
