Chargeback Rate Calculator
A store's chargeback rate from its transactions and disputes — against the monitoring threshold the card networks enforce — with the full cost of each chargeback, the annual bill, and how many disputes the threshold actually allows.
A chargeback costs the sale, the goods that were shipped, a fee from the processor and staff time to fight it.
How the chargeback rate calculator works
A chargeback costs the sale, the goods that were shipped, a fee from the processor and staff time to fight it. Card networks track the rate of chargebacks to transactions and put merchants above about 1% into monitoring programmes with fines and, eventually, loss of processing. The rate is the number that matters; the cost is what makes prevention worth paying for.
Formula: rate = chargebacks / transactions; cost each = order value + fee + handling; allowed = threshold × transactions
Worked examples
| Inputs | Chargeback rate | Note |
|---|---|---|
| 78 in 12,000 | 0.65% | 0.65% — under, but close |
| Over the line | 1.083% | 1.08% — monitoring |
| A strong dispute process | 0.65% | the same rate, a lower cost |
FAQFrequently asked questions
What chargeback rate is acceptable?
Under 0.5% is healthy; the card networks' monitoring programmes start at about 0.9 to 1% of transactions, and merchants who stay above it for months face fines and can lose the ability to take cards.
What does a chargeback really cost?
The order value if you lose it, the goods already shipped, a processor fee of 15 to 40, and the time to gather evidence — often two to three times the order value in total.
Is it worth fighting them?
For genuine fraud and "item not received" with tracking, yes: win rates of 20 to 40% are typical with good evidence. Friendly fraud on digital goods is harder.
How do I reduce them?
Clear billing descriptors, fast refunds when asked, delivery confirmation, address and 3-D Secure checks on risky orders, and answering support tickets before customers call their bank.
Why count transactions, not orders?
Because the networks compute the ratio on card transactions in the month. If most orders are one transaction the difference is small; enter what your processor reports.
