# Chargeback Ratio

The chargeback ratio is the number of chargebacks a merchant receives in a month divided by its number of transactions — Visa counts the same month's transactions, Mastercard the previous month's — and it is the measure the card schemes use to decide whether a merchant is a problem. Above about 0.9–1% (with a minimum count), the merchant enters a monitoring programme with fines that escalate monthly; above 1.8–2%, the acquirer faces pressure to terminate it.

**Also known as:** Chargeback rate, Dispute ratio, Chargeback-to-transaction ratio

## Key facts

- **Used at:** the schemes' merchant monitoring programmes (Visa's VDMP and VFMP, Mastercard's ECP), acquirers' merchant reviews and underwriting, and every payments company's risk dashboard
- **Binding:** the scheme rules — a merchant above the thresholds is placed in a programme, the acquirer is fined per month and passes it on, and persistent offenders are terminated and listed on the MATCH file
- **Typical thresholds (2024–2025):** Visa's standard programme at 0.9% and 100 chargebacks a month, its excessive tier at 1.8%; Mastercard's at 1% and 100 chargebacks (with a "chargeback-monitored" tier from 1.5%); a separate fraud-ratio programme counts fraud-reported transactions by value
- **Typical drivers:** subscription renewals, digital goods, travel, high-ticket electronics, and any business with poor descriptors or slow refunds; a rate under 0.5% is comfortable, 0.5–0.9% is watched
- **Parties:** the schemes, the acquirer or facilitator (which is fined and polices its merchants), the merchant, and the dispute-management vendors who sell the reduction

## How the chargeback ratio works in practice

A merchant with 100,000 transactions in a month receives 950 chargebacks: 0.95%. Under Visa's rules it has crossed the standard threshold and, if it stays there, enters the dispute monitoring programme: a warning month, then fines of $50 per chargeback rising with time in the programme, then a demand that the acquirer fix or terminate. Under Mastercard's, the count against last month's transactions may differ. The acquirer's risk team calls; the merchant's payments manager, who had not been counting, learns what the ratio is.

Bringing it down is a set of known moves: a recognisable payment descriptor; refund faster than the cardholder's bank disputes; pre-dispute alerts (Verifi, Ethoca) that let the merchant refund before a chargeback is filed — those refunds do not count; better fraud screening so that third-party fraud does not become chargebacks; clear cancellation for subscriptions; and representment of first-party disputes, which does not lower the ratio (the chargeback still counts) but recovers the money. Some merchants also raise the denominator with low-value transactions, which the schemes have noticed.

For an acquirer or a payment facilitator the ratio is portfolio management: a merchant in a programme costs fines and attention, and a portfolio with many near the threshold is a book a buyer discounts.

## Example

A subscription merchant runs at 1.1% — 1,300 chargebacks on 118,000 transactions — and enters Visa's programme; fines reach $65,000 in the third month. It changes the descriptor to its brand name and a phone number, enrols in pre-dispute alerts and refunds 70% of alerted cases, introduces one-click cancellation and a cancellation-confirmation email, and tightens fraud rules on first payments. Month four: 620 chargebacks on 121,000 transactions, 0.51% — out of the programme. The alerts cost $0.40 each and the refunds forgo $28,000 a month of revenue the merchant would mostly have lost anyway; the fines stop. Its acquirer, which had drafted a termination letter, instead lowers the merchant's reserve.

## Common mistakes

- Not counting: many merchants learn their ratio from the acquirer's letter.
- Refunds after the chargeback, which count; refunds before it, which do not, arrive too late.
- A descriptor that is a legal entity name and a code.
- Winning representments and thinking the ratio has fallen; it counts filings, not outcomes.
- Acquirers with a portfolio near the thresholds and no monitoring of their own.
