This models full product refunds with no customer-paid shipping for one product/order pattern. It does not predict returns, model partial refunds or replace a cohort profit report. The same rate can hide very different recovery and handling costs. Tax, overhead and unentered costs remain excluded. Read the data and method ↗ How to use the tools

Formula, source and limits

Every original order incurs its entered outbound cost, original payment fee and ad cost. A full return refunds all product revenue.

Returned-order contribution subtracts unrecovered product cost, outbound cost, retained original fees, return shipping, extra handling and original ad cost. Recovered cost is stock value, not immediate cash.

Scenario contribution = kept-order contribution × kept-order share + returned-order contribution × full-return share. The cost break-even return rate rounds down to two decimals.

This models full product refunds with no customer-paid shipping for one product/order pattern. It does not predict returns, model partial refunds or replace a cohort profit report. The same rate can hide very different recovery and handling costs. Tax, overhead and unentered costs remain excluded.
