Chargeback fees and chargeback ratios: what card-network rules and providers’ own terms say

Two different things: the fee and the ratio

A chargeback is a card payment reversed through the card network after the cardholder disputes it with the bank that issued the card. Stripe’s documentation describes the sequence: the issuer creates a formal dispute on the card network, which immediately reverses the payment, and Stripe then debits the merchant’s balance for the payment amount and the dispute fee.

So a chargeback costs a merchant in two ways. The first is the disputed amount: Stripe debits it when the dispute is created, and Square’s terms let it hold chargeback amounts while a chargeback is pending. The second is the provider’s fee for handling the dispute, which the provider sets in its own price list or merchant agreement.

The chargeback ratio is a separate measure: how many disputes a merchant receives compared with how many transactions it processes. Providers watch it under their agreements, and card networks watch it through monitoring programmes such as Visa’s VAMP. A high ratio can lead to reserves, extra fees or termination under the agreement; the fee itself is charged on each dispute whatever the ratio.

Chargeback fees in providers’ own published terms

Some mainstream providers publish their dispute fees; where a provider does not, the fee is in its proposal or merchant agreement. The table below shows published examples as read on 19 October 2026. It is not a comparison of providers: these companies’ restricted-business lists often exclude high-risk sectors, as Zolution’s guide to those lists explains.

Stripe’s prices differ by country, so this guide does not quote a Stripe amount. Check the fee for your own country on the provider’s pricing page, or in your proposal, before you compare.

How the ratio is measured

There is no single chargeback ratio. Each provider agreement defines its own, and each card network uses its own programme measure. Visa’s is the clearest published example.

Because Visa’s ratio counts fraud reports as well as disputes, a merchant can have few chargebacks and still a high VAMP ratio. The fact sheet excludes disputes resolved through pre-dispute solutions and fraud reports that qualify for Compelling Evidence 3.0, each depending on the timing of Visa’s data extract. Mastercard’s programme thresholds are set out in Mastercard’s rule documents, which could not be opened for this guide; it does not quote them.

A worked example

One hypothetical US merchant in one month, with invented figures, shows how the fee and the ratio are separate calculations.

Not meeting Visa’s published merchant thresholds does not mean the provider is satisfied: its agreement may set a lower limit, and the merchant’s events still count in the acquirer’s portfolio ratio.

The time limits in Visa’s rules

Visa’s public rules (chapter 11, edition of 18 April 2026) group disputes into four categories: 10 Fraud, 11 Authorisation, 12 Processing Errors and 13 Consumer Disputes. Each dispute condition has its own time limit. Some examples from the rules:

• Card-absent fraud (condition 10.4): the issuer may raise the dispute within 120 calendar days from the transaction processing date.
• Fraud and authorisation disputes: the acquirer may make a pre-arbitration attempt within 30 calendar days from the dispute processing date, unless the merchant accepted the dispute through Rapid Dispute Resolution.
• The issuer may answer that attempt within 30 calendar days; arbitration may then be filed within 10 calendar days of the issuer’s pre-arbitration response.
• Each transaction is disputed separately, and the acquirer may respond to the original dispute only once (section 11.2.1). If a member does not respond in time, the dispute cycle is closed and that member is responsible for the amount.

Your provider may set you a shorter deadline than the network sets for it, so that it has time to prepare the response. Ask what your deadline is.

What the published documents say lowers disputes

The documents above point to a few legitimate ways disputes are resolved before they become chargebacks. Mastercard describes its Ethoca Alerts service as connecting issuers and merchants to share fraud and dispute data, so that a merchant can stop fulfilment or issue a refund and prevent the need for a chargeback. Visa’s rules provide for Rapid Dispute Resolution, through which a merchant can accept a dispute, and Visa’s fact sheet excludes disputes resolved through pre-dispute solutions from the VAMP ratio.

These tools may carry their own per-alert or per-case fee, which is why Zolution’s proposal terms have a separate alert-fee row. What is never acceptable is changing how a business or its transactions are described to keep a ratio down; Visa’s rules (section 12.5.3.2) let Visa impose a USD 25,000 monthly assessment on the acquirer, or disqualify the merchant, where merchant data was altered to get around VAMP.

What to compare in an offer

• The chargeback fee per dispute, and whether it is refunded if you win.
• Any fee for responding to a dispute, and any alert or pre-dispute fee per event.
• How the agreement defines the chargeback ratio, the limit, and what happens above it: a reserve, a higher rate, extra fees or termination.
• Whether pending chargebacks delay or reduce your payouts.
• Your deadline for answering a dispute, and what evidence the provider needs.

Zolution’s proposal terms show the chargeback fee and the alert fee as separate, optional rows next to the processing rate, reserve and payout terms, so offers can be compared line by line.
