Yes, in most cases they do. Merchants win about one-third of the disputes they face on average, according to the 2024 State of Chargebacks Report. That means the cardholder keeps the money roughly two times out of three.
The headline number is not the whole story, though. Win rates vary sharply by reason code, by the quality of your evidence, and by whether you choose to fight at all. Here is what the data shows, and how to use it.
What Merchant Win Rates Actually Look Like
Three figures tell the real story:
- About one-third. Merchants win roughly a third of all the disputes they face, per the 2024 State of Chargebacks Report.
- About 54%. Mastercard and Datos Insights found that US merchants win about 54% of the chargebacks they represent — counting only the disputes they chose to fight.
- 36.5% versus 56.6%. Accertify's data puts the median win rate for fraud-coded chargebacks at 36.5%, against 56.6% for non-fraud chargebacks.
The gap between one-third and 54% is a selection effect. Merchants who represent selectively fight the cases they can document, and they win more often. Merchants who fight everything, or nothing, drag the average down.
Why the Chargeback Process Favors the Cardholder
The process is built around consumer protection, and it shows in the mechanics:
- The issuing bank makes the initial decision based on the cardholder's claim, before you have said a word.
- The burden of proof sits with you. The cardholder asserts; you document.
- Response windows are set by the card networks and measured in days, not weeks. Miss the window and you lose by default.
- The cardholder can often escalate a decision, while your options narrow at each stage.
This is why the question comes up so often in merchant forums. It is not that merchants cannot win. It is that a merchant who responds late, or with thin evidence, has already lost.
When Merchants Do Win
The reason code matters more than almost anything else. Non-fraud chargebacks — product not received, item not as described, billing errors — come down to documentation, and merchants win a majority of them, 56.6% at the median. Fraud-coded disputes are harder, because proving the cardholder authorized the transaction is harder than proving you shipped a box.
Compelling evidence in practice means:
- Delivery confirmation tied to the cardholder's address
- AVS and CVV match records from the transaction
- Customer communication logs, including any post-purchase contact
- Documented acceptance of your terms, refund policy, and billing terms at checkout
If you fulfilled the order and can show it, fight. If the claim is that the card was stolen and your only evidence is the sale itself, your odds are poor.
Which Chargebacks Are Worth Fighting
Treat representment as a business decision, not a reflex:
- Compare the amount to the cost. Preparing a response takes staff time on top of the dispute fee. A small-ticket dispute with weak evidence is often not worth it.
- Fight non-fraud codes first. The 56.6% non-fraud win rate reflects cases where paperwork settles the question.
- Concede what you cannot document. The 54% win rate on represented disputes exists because merchants who fight selectively win more. Fighting everything lowers your rate and raises your costs.
Reduce the Chargebacks You Have to Fight
The cheapest dispute is the one that never gets filed. Clear billing descriptors, responsive customer service, and a fast refund when the customer has a legitimate complaint all prevent disputes at the source. There are real trade-offs between chargebacks and refunds, and in many cases the refund is the cheaper outcome — we cover that comparison in detail separately.
What Win Rates Mean for High-Risk Merchants
For most businesses, a lost dispute costs the sale plus a fee. For a high-risk business, every chargeback — won or lost — counts toward the ratio your acquiring bank watches, and a ratio that climbs too high threatens the account itself. Winning disputes recovers revenue; preventing them protects the account. You need both.
That is where we come in. We work exclusively with high-risk businesses, so chargeback management is built into how we set up accounts rather than bolted on afterward. If your current processor has put you on notice over your chargeback ratio, or you need a high-risk merchant account that will not fold at the first dispute spike, apply today.
Frequently Asked Questions
Merchants win about one-third of all the disputes they face, according to the 2024 State of Chargebacks Report. Counting only the disputes merchants chose to fight, Mastercard and Datos Insights found US merchants win about 54%. The difference is selection: merchants who fight only the cases they can document win more often.

Yes. Accertify's data puts the median merchant win rate at 36.5% for fraud-coded chargebacks versus 56.6% for non-fraud chargebacks. Non-fraud disputes — product not received, item not as described, billing errors — come down to documentation, and proving the cardholder authorized a transaction is harder than proving you fulfilled an order.
Delivery confirmation tied to the cardholder's address, AVS and CVV match records from the transaction, customer communication logs, and documented acceptance of your terms, refund policy, and billing terms at checkout. If you fulfilled the order and can show it, you have a case worth fighting.
No. Treat representment as a business decision. Compare the disputed amount against the dispute fee and the staff time a response takes, fight non-fraud codes you can document first, and concede cases with no evidence. Selective fighting is why represented disputes win at about 54% while the overall average sits near one-third.
Yes. Every chargeback counts toward the ratio your acquiring bank watches, won or lost, and a ratio that climbs too high threatens the account itself. Winning disputes recovers revenue, but only prevention protects the account — high-risk merchants need both.
