TOOL IQ BRIEFING

One useful business decision each week.

New calculators, practical examples and timely UK or US small-business guidance.

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.

Retained contribution = retained revenue × gross margin − returned orders × processing cost

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.

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.
