A chargeback is when you ask your bank to get your money back because a shop did not keep its promise. The bank looks at the proof from both sides. If the shop cannot show it did its job, the money goes back to you.
Let’s see it in real life…
Rafael’s football club sells new team jerseys at the start of the season.
Aunt Nadia pays for one with a bank card at the club shop. The seller promises: “Ready in two weeks!”
Two weeks pass. Then four. Still no jersey.
Rafael and Aunt Nadia go back, but the shop is closed and nobody answers the phone.
So Aunt Nadia calls the bank: “We paid, but we never got the jersey.”
The bank writes to the shop’s bank and asks: “Can you prove the jersey was delivered?”
The shop has no proof, because the jersey was never made.
A few weeks later, the money is back on Aunt Nadia’s card.
Rafael still plays in the old jersey, but the money is safe.
That is a chargeback.
Tiny recap
- It means… asking your bank to take a payment back when the seller did not keep its promise.
- It helps when… you paid for something that never arrived, or that is not what was promised.
- Watch out for… it is not a trick to get free things. If you got what you paid for, talk to the shop, not to the bank.
…detailed for specialists
A chargeback is a forced reversal of a card payment. The cardholder disputes a transaction with the bank that issued the card, the issuer pulls the funds back from the merchant through the acquirer, and the merchant can contest with evidence. It protects cardholders against fraud, non-delivery and billing errors, and it costs merchants every time.
Chargebacks matter more in 2026 than when this #PayDecoding was first published. Volumes keep rising, friendly fraud has become the main concern for merchants, and Visa’s new monitoring program counts fraud reports and disputes together, with a stricter merchant threshold since April 2026. For acquirers, PSPs and PayFacs, a merchant’s dispute ratio is now a portfolio risk, not a merchant problem.
What is a chargeback?
Chargebacks were designed as a consumer protection: if a card is stolen, or a merchant does not deliver, the cardholder should not have to chase the money alone. The card scheme rules give the issuer the right to take the funds back and let the merchant answer.
A chargeback is not a refund. A refund is started by the merchant, costs little and closes the matter. A chargeback is started by the cardholder through the bank. It comes with a fee, a deadline, paperwork and a mark on the merchant’s dispute ratio. And if a merchant spots a mistake before the payment settles, a void transaction avoids both.
Disputes fall into four broad families:
- Fraud: the card was used without the cardholder’s consent (third-party fraud).
- Authorization: the transaction was processed without a valid authorization, or after a decline.
- Processing errors: duplicate charge, wrong amount, late presentment.
- Consumer disputes: goods not received, not as described, subscription not canceled.
Then there is friendly fraud, or first-party misuse: the real cardholder disputes a purchase they made and received, by mistake, by forgetting, or on purpose.
How a chargeback works
- The cardholder disputes the charge with the issuer, often in a banking app in a few taps.
- The issuer assigns a reason code and sends the chargeback through the card network to the acquirer.
- The acquirer debits the merchant, or the PayFac that serves it, for the amount plus a chargeback fee.
- The merchant accepts or fights. To fight, it sends evidence (representment): order details, delivery proof, terms accepted, previous purchases.
- The issuer reviews the evidence. If it still disagrees, the case can go to pre-arbitration and then to the card scheme, which decides and charges fees to the loser.
Deadlines are strict. At Mastercard, for example, cardholders generally have 120 days from the transaction to file, up to 540 days for some non-delivery cases, and merchants have 45 days to respond. Before the formal dispute, pre-dispute tools such as Visa Order Insight and Mastercard’s Ethoca alerts let merchants share order data or refund the customer before a chargeback is even filed.
Chargebacks in numbers (2026)
- Volume: Mastercard estimates 261 million chargebacks in 2025, rising 24% to 324 million a year by 2028. Their value is forecast to grow from $33.79 billion to $41.69 billion.
- Fraud share: third-party and first-party fraud together account for about 45% of merchant chargeback volume, according to the same Mastercard study. The average chargeback is worth $110 in the US and $82 in the UK.
- United States: American consumers filed 158 million transaction disputes in 2025, up 29% from 2021 and faster than card transactions, according to figures reported by Bloomberg.
- Friendly fraud: merchants surveyed for Chargebacks911’s 2026 Field Report attribute 43.8% of their chargebacks to friendly fraud, and 83.4% of enterprise merchants saw it increase.
- Win rate: merchants win only 16.7% of disputes on average, 15.3% in Europe. Resolving a single first-party misuse dispute costs $82 on average.
- Europe: fraud on cards issued in the EEA reached €1.33 billion in 2024, up 29% in a year.
Chargeback thresholds: Visa VAMP and Mastercard ECP
Visa Acquirer Monitoring Program (VAMP)
Since April 2025, VAMP has merged five fraud and dispute programs into one, with an advisory period that ran until 30 September 2025. Its ratio adds fraud reports (TC40) and disputes (TC15) and divides them by settled card-not-present transactions. A merchant becomes “Excessive” in Asia Pacific, Canada, Europe and the US at 2.2% until March 2026 and 1.5% from 1 April 2026, with at least 1,500 fraud and dispute events a month. Acquirers are monitored too: their whole portfolio is “Above Standard” from 0.5% and “Excessive” from 0.7%.
Because one transaction can count twice (as a fraud report and as a dispute), stopping fraud early now does double duty.
Mastercard Excessive Chargeback Program
Mastercard flags an Excessive Chargeback Merchant from 100 chargebacks and a 1.5% ratio in a month, and a High Excessive Chargeback Merchant from 300 chargebacks and 3%. Assessments climb with each month above the threshold, up to $100,000 or $200,000 a month after 19 months.
Chargebacks: what changes for PSPs, PayFacs and platforms
The liability runs up the chain
When a sub-merchant cannot pay its chargebacks, the PayFac pays, and if the PayFac cannot, the acquirer does. That is why dispute risk starts at onboarding: business model, delivery times, refund policy, expected ticket size. Rolling reserves, payout delays and per-merchant dispute ratios, tracked daily rather than monthly, protect the portfolio before VAMP does it for you.
Prevent before the dispute
A clear billing descriptor, easy cancellation, fast refunds and pre-dispute alerts remove a large share of disputes before they reach the scheme. Strong customer authentication through 3-D Secure shifts fraud liability to the issuer in most cases. Velocity limits stop card-testing attacks that generate fraud reports by the hundreds.
Fight with data, not letters
Visa’s Compelling Evidence 3.0 lets merchants answer “I didn’t make this purchase” disputes (reason code 10.4) with the cardholder’s history: two earlier undisputed transactions, 120 to 365 days old, sharing at least two data elements such as IP address, device ID or shipping address. Since 17 October 2025, Visa qualifies eligible transactions authenticated with Visa Secure or Visa Data Only automatically, and fraud reports resolved this way are excluded from VAMP. The work for PSPs is to store and pass that data with every transaction.
New rules in Europe
Under the Payment Services Regulation agreed alongside PSD3, whose final adoption was still pending in October 2026, issuers will be able to recover fraud losses from acquirers, which makes chargebacks more likely to travel down the chain. Note also that bank transfers and instant payments have no chargeback: protection there relies on checks before the payment.
Reconciliation
Each dispute creates several money movements: the debit, the fee, the possible reversal after representment, the arbitration fee. Matching them to the original payment and the right sub-merchant is what keeps payouts and margins correct. NORBr provides the white-label payment infrastructure to route, onboard, pay out and analyze, under your own brand.
Is chargeback management worth it in 2026?
Yes, and it is no longer optional. With dispute volumes rising, friendly fraud a growing concern and a 1.5% Visa threshold, every merchant and every platform needs a plan: prevent with clear communication and refunds, detect fraud early, and fight only the disputes it can win, with data.
Frequently Asked Questions
What is a chargeback?
A chargeback is the reversal of a card payment started by the cardholder through their issuing bank. The issuer takes the funds back from the merchant via the acquirer, and the merchant can contest with evidence. It covers fraud, non-delivery, processing errors and goods not as described.
What is the difference between a chargeback and a refund?
A refund is initiated by the merchant, who returns the money voluntarily. A chargeback is initiated by the cardholder’s bank, comes with a fee and a deadline, and counts in the merchant’s dispute ratio monitored by Visa and Mastercard.
What is friendly fraud?
Friendly fraud, or first-party misuse, is when the genuine cardholder disputes a purchase they made and received, by mistake or on purpose. Merchants surveyed in 2026 attribute about 44% of their chargebacks to it.
What is the Visa VAMP threshold in 2026?
Since 1 April 2026, a merchant in Asia Pacific, Canada, Europe or the US is rated Excessive under VAMP when fraud reports plus disputes reach 1.5% of settled transactions, with at least 1,500 events in the month. The threshold was 2.2% before.
How long does a customer have to file a chargeback?
It depends on the card scheme and reason code. At Mastercard, cardholders generally have 120 days from the transaction, and up to 540 days for some non-delivery cases. Merchants then have 45 days to respond with evidence.
