Chargeback Fee Calculator

The maths behind it

The cost of a chargeback is the reversed transaction amount, plus the chargeback fee, plus the goods already shipped, plus the original processing fee which is not returned, plus the staff time to respond.

Total cost = order value + chargeback fee + cost of goods + original processing fee + handling. It is consistently two to three times the order value.

Putting numbers to it

A $58 order charged back. The $58 is reversed. The chargeback fee is $15. The goods cost $26.10 and are gone. The original $1.98 processing fee is not returned. Fifteen minutes of staff time to gather evidence at $28 an hour is $7.

Total cost $108.08 on a $58 order, 186% of the order value, and 339% of the $31.90 contribution it would have produced.

So one chargeback wipes out the contribution from 3.4 successful orders. At a 0.5% chargeback rate, that is 1.7% of all contribution consumed by disputes.

Where it is unreliable

The fee is charged whether or not you win. Successfully defending a chargeback returns the transaction amount and typically not the fee, so a won dispute still costs money.

The threshold consequences are also more serious than the individual costs. Card schemes place merchants above roughly 0.9% to 1% chargeback ratios into monitoring programmes with escalating fines and, eventually, loss of card acceptance entirely.

How to act on this

Track the chargeback ratio monthly against the scheme thresholds, not just the absolute cost. The cost is survivable and the ratio is existential.

Then invest in prevention rather than representment. Clear billing descriptors, recognisable order confirmations, responsive support and delivery tracking prevent more chargebacks than any dispute process wins back.

Friendly fraud and the descriptor problem

A substantial share of chargebacks are not fraud in any conventional sense, the cardholder genuinely made the purchase and did not recognise it on their statement. That category is usually the largest single cause.

The fix is unglamorous: a billing descriptor that matches the trading name the customer knows, a phone number in the descriptor where the processor supports it, and an order confirmation that arrives immediately and is easy to search for.

Businesses that trade under a name different from their registered entity, and use the entity name as the descriptor, generate a steady flow of chargebacks entirely from that mismatch. It is a configuration change that takes ten minutes and it removes a category of dispute that no amount of evidence submission would have won.

The pre-dispute alerts offered by the card networks, which notify a merchant of an impending chargeback and allow a refund before it is filed.

Refunding costs the order value; a chargeback costs the order value plus the fee plus the ratio impact. Where the ratio is anywhere near a monitoring threshold, paying for alerts and refunding proactively is cheaper than defending, even on disputes you would have won.

One last note on evidence: the representment window is short and the required documentation is specific, so a template assembled in advance: order record, delivery proof, terms accepted, communication history. Is worth far more than good intentions on the day.
