How the chargeback win rate is calculated
The simple formula divides the chargebacks won by the chargebacks contested in the same period. A merchant that contests 40 chargebacks and wins 18 has a win rate of 45%. The figure changes with the choices behind it:
- Denominator: chargebacks contested, or all chargebacks received
- Count or value: the number of cases, or the money recovered
- What a win is: the first response accepted, or the case closed for good
- Period: cases are decided weeks after they open, so a month's rate settles late
- Alerts and refunds: disputes settled before a chargeback are usually left out
Why the win rate matters, and what it hides
Payment providers and dispute tools quote a win rate to show what their evidence handling is worth, and merchants use it to decide which reason codes are worth contesting. A merchant that contests only its strongest cases has a high win rate and recovers little. The net recovery rate, the money won back as a share of all money charged back, is the fairer measure.
Winning does not undo the count. Mastercard's Excessive Chargeback Programme, for one, measures the chargebacks an acquirer received for a merchant in a month, so a case won later has already been counted. Only fewer disputes lower the chargeback rate.
