# Pricing High-Return Categories: The Math of Round-Trip Shipping

How much do round-trip shipping and repackaging cost you per return? Work out your real contribution profit.

## Short answer

Expected unit contribution with returns is (1 − return probability) × profit from a successful sale − return probability × the extra loss from a return. With a $300 price, $45 profit per successful order, a $90 return logistics loss and a 10% return rate, expected contribution is $31.50. This is a sample cost model. Every return costs something different, and an XPrice integration does not cover all return data automatically.

## How does the return rate eat into sales profit?

Say each sale books $45 of contribution profit, while one return costs $90 in shipping, repackaging and handling. That single return can create **an extra loss equal to the contribution of two successful sales**. Don't generalize it, though. The real figure depends on your shipping agreement, whether the product can be resold and commission refunds.

## How to calculate expected unit contribution with returns

**Expected contribution = (1 − R) × K − R × C**. R is the return probability. K is the unit contribution of a completed order. C is the assumed extra operating and logistics loss when a return happens. State clearly what K and C include, and never deduct the same shipping fee twice.

## Sample return cost table for a $300 product

| Contribution rate without returns | Profit without returns | 5% returns | 10% returns | 20% returns |
| --- | --- | --- | --- | --- |
| 10% | $30 | $24 | $18 | $6 |
| 15% | $45 | $38.25 | $31.50 | $18 |
| 20% | $60 | $52.50 | $45 | $30 |

Assumption: C is a fixed $90 extra loss per return. Figures are illustrative. Tax, price-based commission and the product's condition after return can be added separately. A positive result means reduced contribution profit, not a loss.

## What data to collect

- Realized sales and return quantities per SKU
- Round-trip shipping, repackaging and the cost of unsellable returns
- The platform's commission and coupon refund rules
- Return probability by category and period
