Chargeback Ratio Explained: The Number That Decides Whether You Keep Your Processor
If there’s one number that gets accounts closed, it’s this one.
How it’s calculated
The basic version is:
Chargeback ratio = disputes in a month ÷ transactions in that month
Networks and processors calculate it slightly differently (some use the previous month’s transactions, for example), but the idea is the same.
The thresholds
Card networks run monitoring programs for merchants with too many disputes. Thresholds depend on the network and the program, and they change over time, but they typically start around 1% or more, sometimes with a minimum dispute count. Mastercard’s program, for example, has used 1.5% and 100 chargebacks in a month as its entry point.
Processors usually act well before you hit network thresholds. Treat anything near 0.75% as a warning sign.
Why SaaS and AI get hit
- Unrecognized charges: the statement descriptor doesn’t match your brand name.
- Forgotten subscriptions: free trials that roll into paid without a reminder.
- Unmet expectations: “the AI didn’t do what I wanted.”
- Friendly fraud: customers who used the product and then dispute anyway.
- Card testing: fraudsters testing stolen cards on your signup flow.
How to bring it down
- Use a recognizable statement descriptor, ideally your product name plus a support URL.
- Send trial-ending and renewal reminders before charging.
- Make cancelling easy. Hard-to-cancel subscriptions get disputed instead.
- Refund quickly when someone’s clearly unhappy. A refund costs less than a dispute.
- Block card testing with CAPTCHA, velocity limits and 3D Secure where appropriate.
- Answer every dispute with evidence: logins, usage, and the terms the customer agreed to.
A low, stable ratio is the best thing you can bring to any underwriting review.
FAQ
What is a good chargeback ratio?
As low as you can get it. Card network monitoring programs typically start around 1% or more depending on the network and program, and many processors get uncomfortable well below that. Aim for under 0.5%.
Do refunds count as chargebacks?
No. A refund you issue isn't a chargeback. That's exactly why refunding a customer who's clearly unhappy is often better than letting them dispute the charge.
