Calculate chargeback ratio by dividing total chargebacks by total transactions in a given period, typically expressed as a percentage.
How It Works in Practice
- 1Track all chargebacks received within the calculation period using chargeback reason codes and case numbers
- 2Count total transaction volume for the same period, excluding refunds and voids from the denominator
- 3Divide chargeback count by transaction count and multiply by 100 for percentage representation
- 4Calculate separate ratios by card brand as Visa, Mastercard, and American Express have different thresholds
Common Pitfalls
Using settlement date instead of transaction date creates timing mismatches that underreport current risk exposure
Excluding pre-arbitration cases from calculations violates card scheme monitoring program definitions
Failing to segment by merchant category code (MCC) when benchmarking against industry standards leads to false performance assumptions
