Counted as a refund
A refund gets the stock back and its cost credited; a dispute does neither. Treating the two the same credits goods that never come back, and understates every chargeback by their entire cost.

Fighting it, and how often it happens
Evidence takes real time, and the time is spent whether or not you win.
↑ ↓ to nudge, Shift for ten. Commas or dots both work.
A chargeback is not a return: the goods almost never come back, so their cost stays on the statement with the sale and nothing is credited. The lost case is the money without its VAT, the fee and the time, and a won case still costs the fee and the time. That is why prevention, clear billing descriptors, reachable support and honest delivery dates, is worth far more per euro than winning cases after the fact.
€123,33 when it is lost and €38,33 when it is won, weighted by your 35,0% win rate. At 6 a month that is €6.737,76 a year.
An estimate from flat rates. In nouz every order is priced from the costs of its own day.
A chargeback cost calculator prices a disputed order properly: the money returned, less the VAT that comes back, the dispute fee charged whether you win or lose, and the time spent on evidence, weighted by your own win rate. The goods and the parcel stay costs of the sale, so they are never counted twice.
The formula
That single difference is why disputes are so much more expensive than refunds. The money goes back, less the VAT the tax office returns, the customer keeps the product, the parcel was already paid for, the gateway charges its dispute fee whichever way the case goes, and somebody spends half an hour assembling evidence.
Winning helps less than it feels like it should. A won case still costs the fee and the time, so a store with a healthy win rate is still paying a real monthly amount for the privilege of defending itself.
Which is the argument for prevention over litigation. An unrecognisable billing descriptor, a delivery that arrived late, support nobody could reach: those produce more disputes than fraud does in most stores, and all three are cheaper to fix than to win.
Where it goes wrong
Chargebacks are rare enough to feel like noise and expensive enough to deserve a line.
A refund gets the stock back and its cost credited; a dispute does neither. Treating the two the same credits goods that never come back, and understates every chargeback by their entire cost.
Winning does not refund the dispute fee or the hour spent proving delivery. A store that wins two thirds of its cases and thinks those cost nothing is understating its dispute bill by exactly that share.
Evidence gathering is somebody’s afternoon: order records, tracking, delivery confirmation, correspondence, submitted before a deadline. Priced at a real hourly cost it frequently exceeds the dispute fee itself.
Beyond a threshold, card schemes put merchants into monitoring programmes with penalties and, eventually, processing risk. That is a business continuity issue rather than a cost line, and it arrives long after the pattern that caused it started.
Worked example
The calculator’s defaults: a €101,15 gross order at 19% VAT, a €15 dispute fee, 40 minutes of evidence at €35 an hour, and a 35% win rate over six disputes a month. The goods and the parcel were costs of the sale and stay there, so they are not counted again.
Lost, the case costs €123,33. Won, it still costs €38,33. At a 35% win rate the expected cost of one dispute is €93,58.
Six disputes a month is €561,48, which is €6.738 a year, or about 13 healthy orders every month spent replacing money that already arrived once. On €60.000 of monthly net revenue that is 0,9% of the business.
Note what the arithmetic exposes: winning does not make a dispute free. A won case still costs €38,33, 31% of a lost one, in the fee and the time, which is why preventing a dispute beats winning it.
