The real cost of returns in ecommerce
A return is not a sale that never happened: it is a sale that happened, cost money and then came back. Here is the full breakdown, with the provision per order and the maximum rate your margin can absorb.

In most spreadsheets a return shows up as revenue reversed. That would be true if the money travelled back the way it came, and it does not: the outbound leg already shipped, the gateway fee often stays where it is, the packaging was destroyed on opening, and somebody has to spend time inspecting what comes back.
Counting only the return shipping — the most visible cost — usually means booking less than a third of the real impact.
It left the warehouse, it reached the customer, and that money does not come back. If you charged for shipping, you will also have to refund it.
If you offer free returns, you pay it. The one cost almost everybody counts.
On refund, many gateways return only part of their fee, or none. Worth checking in your provider's terms: on small baskets, where the flat part weighs heavily, it moves the result quite a bit.
The box, the filler and the labels are not reusable.
Receiving, opening, checking condition, relabelling, restocking and handling the refund. If you do not have the figure, estimate the minutes per return and multiply by your hourly cost.
Worn clothing, opened cosmetics, damaged boxes, incomplete items. In some categories it is a small share; in others half the return turns into inventory loss.
Compare two scenarios with the same customer. In the first they do not buy: you gain nothing and lose nothing. In the second they buy and return: you gain nothing and pay the direct cost.
But the comparison that really matters is against the order that sticks, because that is the real alternative:
At a 19.77 contribution and a 14.05 direct cost, the gap between an order that sticks and one that comes back is 33.82. In other words: it takes 1.7 new sales just to offset one return.
Here is where all of this becomes practical. If you know what returns cost you in a month, you can spread that cost across all orders and work with a realistic average margin instead of the margin of the order that goes well.
That figure is what belongs in any pricing or advertising calculation as a variable cost. Without it, the break-even ROAS you compute is too optimistic, and so is every bid built on it.
There is a return rate at which the channel stops contributing: what the kept orders earn equals what the returned ones cost.
It is not a target, it is a wall. And its shape is revealing: the bigger your margin, the more returns you can absorb; the more expensive processing a return is, the fewer. A business on thin margins with expensive reverse logistics can hit the wall at 25%, which in high-return categories is a precarious place to be.
What is useful is the distance between your actual rate and the wall, and what each percentage point closer costs you.

| Net revenue | 41.32 |
| Product cost | -15.00 |
| Outbound shipping | -4.00 |
| Packaging | -0.80 |
| Gateway fee (2.9% + 0.30) | -1.75 |
| Contribution of a kept sale | 19.77 |
| Cost of one return | Amount |
|---|---|
| Outbound shipping lost | 4.00 |
| Packaging | 0.80 |
| Gateway fee not recovered (100%) | 1.75 |
| Return shipping | 4.00 |
| Inspection and processing | 2.00 |
| Unrecoverable product (10% of 15) | 1.50 |
| Direct cost | 14.05 |
With 80 returns out of 1,000 orders, monthly contribution falls from 19,772.31 to 17,066.53. That is 2,705.79 a month of loss, 13.69% of the channel's profit, and a provision of 2.71 per order.
| Equivalent calculation | Value | Unit |
|---|---|---|
| Returns loss | €2,705.79 | per month |
| Contribution per retained order | €19.7723 | per order |
| Equivalent orders | 136.85 | orders per month |
Put another way: €2,705.79 per month divided by €19.7723 per order is approximately 136.85 orders per month spent on returns.
Most returns in fashion and footwear are about fit or expectation: photos that misrepresent the colour, missing measurements, optimistic descriptions. Exact measurements, per-product size guides and photos with a scale reference cut the “not what I expected” returns, which are the most expensive because the product comes back used.
Negotiate reverse-logistics rates, use drop-off points instead of home collection, and simplify the warehouse process. Every unit you take off the direct cost raises your maximum sustainable rate.
Packaging that lets you reship the product, and a route for refurbishing what comes back marked. Going from 10% to 5% unrecoverable product is 0.75 per return in the example.
Free returns raise conversion and also raise the return rate. The question is not whether they are good or bad, but whether in your case the conversion gain pays for the cost increase. With the provision per order calculated, that comparison can be made with numbers.
Before changing your returns policy, check your legal obligations in every market you sell into. In the European Union and the United Kingdom, distance selling carries statutory cancellation rights, and other markets have their own rules. Check with your adviser: this guide is not legal advice.
Run your numbers
The calculator turns your return rate into money: direct cost, monthly loss, provision per order and maximum sustainable rate.
Calculate my cost of returnsIt varies so much by sector and channel that any general figure misleads, and we are not going to invent one. Measure yours (returns in the month over orders in the month) and compare it against your own trend and against your maximum sustainable rate, which is a number specific to you.
It depends on the provider and the transaction type: some return the percentage part but not the flat one, others nothing. Worth checking in your own terms, because on small baskets it can be the second-largest cost of the return.
Ideally count it for a month: out of every 100 units returned, how many go back to A-grade stock, how many to outlet and how many are written off. Without that record, start conservative and refine it once you have data.
Yes. If you do it yourself, the cost is your time and it is real: those are hours you are not spending selling.
The calculator models full returns, which is the most expensive case. For a partial refund, a reasonable approximation is to reduce the order value and the product cost proportionally while keeping the transport and processing costs whole.
Considerably, and invisibly: platforms count the conversion, not the later return. Your CPA per kept sale is worse than the dashboard shows. Putting the provision per order into the ROAS calculator corrects that bias.
