What Chargeback Ratio Gets Your Merchant Account Terminated?

One percent. That is the number most acquirers write into their merchant agreements, and it is the number they point to when they close an account. Visa and Mastercard set their own monitoring thresholds higher, at 1.5%. Your processor does not have to wait for the card brands. It can terminate at 1% because your contract says it can.

That gap is where merchants get hurt. You watch the card brand numbers, you stay under them, and your processor still pulls the plug. Nothing went wrong with your math. You were reading the wrong rulebook.

How Your Chargeback Ratio is Calculated

Your ratio is a count, not a dollar figure. Divide the number of chargebacks you received in a month by the number of transactions you processed. One hundred chargebacks on 10,000 transactions is 1%.

Two details trip people up. Mastercard measures this month’s chargebacks against last month’s sales volume, so a drop in sales can push your ratio up even when disputes hold steady. And a refund issued after a dispute is filed does not remove the chargeback from the count.

Small merchants feel this most. At 2,000 transactions a month, 20 disputes put you on the line.

What The Card Brands Measure in 2026

Visa retired the old dispute and fraud monitoring programs and replaced them with the Visa Acquirer Monitoring Program. VAMP combines fraud reports and disputes into a single number: TC40 fraud reports plus TC15 disputes, divided by settled card-not-present transactions.

The merchant threshold dropped from 2.2% to 1.5% on April 1, 2026, in the US, Canada, the EU, and Asia-Pacific. Monitoring starts once you hit 1,500 combined fraud and dispute events in a month. Enrolled merchants are assessed $8 per fraudulent or disputed transaction.

One transaction can count twice under VAMP, once as a fraud report and once as a dispute. That is new, and it catches people.

Mastercard runs two tiers. The Excessive Chargeback Merchant program starts at 100 chargebacks in a month and a ratio of 1.5%. The High Excessive tier starts at 300 chargebacks and 3%. Fines escalate the longer you sit there, from $1,000 in month two to $100,000 or more past the eighteen-month mark.

The attorneys at Global Legal broke down what the new caps mean for real portfolios in PEP Episode 084, VAMP Caps and Chargebacks. The short version from that conversation: merchants ran at 1.5% or 2% for years without hearing a word, because processors made money on chargeback fees. That era is over.

Why Your Processor Terminates Before You Hit The Brand Threshold

Acquirers now carry their own risk. Under VAMP, an acquirer is flagged as above standard at 0.5% and excessive at 0.7% across its whole portfolio, and Visa began enforcing those fines in January 2026.

Read that again. Your acquirer gets penalized at half a percent. You are allowed 1.5%.

So the acquirer protects itself. It offboards the accounts driving its portfolio number before the brands come knocking. A few profitable high-risk merchants can account for most of a portfolio’s problems, and every risk team in the industry knows which accounts those are. PEP Episode 093 covers how portfolio risk decisions get made in real time.

This is why the 1% clause in your agreement matters more than anything Visa publishes.

What Termination Actually Costs

Losing the account is the beginning, not the end.

Your processor will hold funds. Reserve accounts are commonly released 180 days after closure, but many agreements let the processor hold until liability expires, which has no fixed end date.

Then there is MATCH. If your ratio meets the acquirer’s threshold, the acquirer can report your business to the MATCH list under reason code 12, excessive chargebacks. That placement lasts for five years and makes it very hard to get new accounts. It is also frequently the result of processor error, which is why removal is often achievable.

If You Are Near The Line

Pull your agreement and find the termination clause. Find the number in it. That is your real threshold, not the one in a card brand bulletin.

Then look at what the agreement lets the processor do next. Reserve percentage, hold period, notice requirements, MATCH reporting. Those terms are negotiable before you sign and much harder to argue after.

If your account has already been closed or your funds are being held, the questions are whether the processor followed its own contract, whether the ratio was calculated correctly, and whether any MATCH report was accurate.

FAQs

What chargeback ratio is considered excessive? 

Most acquirers treat 1% as excessive and reserve the right to terminate at that level. Visa’s VAMP program flags merchants at 1.5% of card-not-present transactions. Mastercard’s Excessive Chargeback Merchant program starts at 100 chargebacks in a month, combined with a 1.5% ratio.

Can a processor terminate my account without warning? 

Usually yes. Most merchant processing agreements allow immediate termination for excessive chargebacks, suspected fraud, or a material breach, with no cure period. Notice requirements vary by contract, and whether the processor followed them is often the first thing worth reviewing.

How is a chargeback ratio calculated? 

It is the number of chargebacks in a month divided by the number of transactions, counted rather than measured in dollars. Mastercard divides this month’s chargebacks by last month’s sales count. Visa’s VAMP ratio adds fraud reports to disputes and divides by settled card-not-present transactions.

Does exceeding the chargeback threshold put me on the MATCH list?

 It can. An acquirer that terminates for excessive chargebacks may report the business to MATCH under reason code 12. Placement lasts five years, is not automatic, and is often the product of processor error, which is why removal is frequently possible.

How long does a processor hold reserve funds after termination?

Most agreements state 180 days after account closure. Many also contain language allowing the processor to hold funds until liability expires, which has no fixed end date. The Card Brand Rules impose a reasonableness standard, and that standard is what payments counsel uses to force release.
