METHOD & GUIDANCE
How this calculation works
Keep every input on the same time basis—for example, one month or one financial year—and do not mix cash figures with accrual figures. Tool IQ recalculates every output immediately; nothing you enter is saved or sent to us.
How to use the result
Model returns by product category and sales channel, then compare retained contribution rather than judging the return rate in isolation.
Worked example
At 2,000 orders, 65 average order value and a 12% return rate, the opening case refunds an estimated 15,600 of revenue before processing cost.
Common mistakes
- Using item returns with an order-based denominator.
- Assuming every return has the average order value.
- Ignoring lost shipping, inspection, fraud and markdown costs.
Frequently asked questions
Is the ecommerce return rate calculator free?
Yes. It requires no account and stores no calculation inputs.
Can I use the answer for a formal filing?
No. It is a planning estimate, not accounting, tax, legal or investment advice. Confirm material decisions with a qualified professional.
Which period should I use?
Keep every input on the same basis—for example, one month or one financial year. Use current figures first, then save a cautious scenario for comparison.
