Return cost calculator
What a returned order actually costs, itemised: the margin handed back, the parcel already shipped, the fee the gateway kept, the journey back, the bench, and the goods that cannot go out again at full price.
A return cost calculator adds up what a returned order actually costs: the margin reversed, the outbound parcel and payment fee already spent, the return label, the time at the returns bench, and the share of goods that cannot go back on the shelf at full price.

Getting it back and getting it saleable
The half of a return that no refund report ever shows.
What this return actually costs
€70,41
The refund was €85,00 and most of the goods came back, so the goods are not the loss. The loss is 1,34 times the margin the sale had earned, and it takes 1,6 good orders to replace it.

This is why return rate matters more than refund totals. A product returning at twice the catalogue average can be the worst earner in the store while its revenue ranking looks excellent, because the ranking counts what it sold and not what it gave back.
See return costs per product, nightlyThe formula
The refund is visible. The damage is somewhere else
Returns are misjudged in both directions, which is why they need itemising rather than estimating. The refund overstates the loss, because most of the goods come back saleable. And it understates it at the same time, because the parcel that went out, the fee the gateway kept and the minutes at the returns bench are all real and none of them are in the refund figure.
Netted out, the damage on an ordinary order runs a third above the margin the sale had earned. That is the sentence worth remembering: a return does not merely cancel a sale, it costs more than the sale made.
The last row is the one that changes behaviour. Divide the damage by what a healthy order contributes and a return stops being a customer service statistic: it becomes a number of sales that have to happen again before the month is level.

Where it goes wrong
Four ways returns stay cheaper on paper than in the bank
Every one of these leaves the true cost outside the report a merchant actually reads.
Only the refund counted
A refund report says money left. It does not say the parcel shipped, the gateway kept its fee, someone inspected the goods and a share of them were marked down. Those are the costs that make returns worth reducing rather than merely accepting.
Return costs booked to the original month
A return lands weeks after its order. Booking it backwards improves a month you already closed every time the present one bleeds, which is how a store loses trust in its own history. The refund day is the honest day.
One return rate for the whole catalogue
Returns concentrate brutally: sized and fit-dependent items return at multiples of the store average. A catalogue average hides exactly the products where a fix is available and worth making.
Assuming everything is resellable
Opened packaging, worn items and anything seasonal that comes back late cannot go out again at full price. The share that cannot is a real write-down, and it is usually the largest single surprise in this arithmetic.
Worked example
An €85 order that came back
The calculator’s defaults, on the example store’s economics: an €85,00 net order at a 38% cost of goods, €6,40 of outbound fulfilment, a gateway taking 1,9% of the gross, a €4,95 return label, €2,50 of inspection, and 85% of goods going back on the shelf at full price.
The margin reversed is €52,70. The costs the refund never mentions add another €17,71.
€70,41 against a margin of €52,70: the return cost 1,34 times what the sale had earned. At €44,68 of contribution per healthy order, it takes 1,6 more sales just to get back to where the store stood before the original order was placed.
Run that against a product returning at 25% and the ranking of your catalogue changes: its revenue is real, and a quarter of it is being handed back with interest.
Questions
Returns, answered
How much does a return really cost?
More than the margin it reverses, and that is the number that surprises people. On an €85 order the margin handed back is €52,70, and the parcel, the uncredited fee, the return label, the restocking and the markdown on unsaleable goods add roughly €17 on top, so the damage runs about a third above the margin the sale had earned.
Is the refund the loss?
No, and treating it that way misstates returns in both directions. Most of the goods come back saleable, so the refund overstates the loss by the cost of those goods. But the outbound costs, the fee and the returns bench are real losses the refund never mentions, which is why the total has to be itemised rather than assumed.
Do I get the payment fee back on a refund?
Generally no. The gateway moved the money and keeps its cut, which makes a refunded order slightly worse than a sale that never happened. A conservative statement books the fee as charged on the original order and never credits it, which is exactly what this calculator does.
How many orders does one return cost me?
Divide the damage by what a good order contributes. On the example figures that is about 1,6 orders: every return needs one and a half healthy sales just to get back to level. Stated that way, a return rate becomes a sales target rather than a customer service statistic.
How do I reduce returns without punishing customers?
Prevent rather than charge. Most returns are decided before the parcel ships: a size chart that does not match, a photo that flatters the colour, a delivery estimate that slipped. Fixing those costs nothing per order and usually improves conversion, which no return fee has ever done.
