What to Expect
Anything below 0.5% is healthy. Between 0.5%–0.9% you're in a warning zone. Above 0.9% on Visa or 1.0% on Mastercard you're in the Chargeback Monitoring Program — which risks account termination and fines up to $100/chargeback.
Understanding Chargeback Ratios — What Every Merchant Must Know
A chargeback occurs when a cardholder disputes a transaction with their bank, and the funds are forcibly returned from the merchant's account. The chargeback ratio is the percentage of your transactions that result in a chargeback — and it's one of the most closely monitored metrics by card networks, acquirers, and payment processors worldwide.
How Is the Chargeback Ratio Calculated?
Card networks use slightly different formulas. Here is the standard calculation used by both Visa and Mastercard:
Chargeback Ratio = (Chargebacks Received This Month ÷ Transactions Processed This Month) × 100
Example: 12 chargebacks ÷ 1,200 transactions = 0.01 = 1.0% ratio
Important: Visa counts chargebacks in the month they are received, while Mastercard counts them in the month the original transaction occurred. This distinction matters — it's possible to have a ratio above threshold on one network but not the other in the same month.
Network Threshold Programs
Both Visa and Mastercard run formal programs to monitor and penalize merchants with elevated chargeback ratios:
| Network | Program | Threshold | Min. Monthly CBs | Status |
|---|
| Visa | Early Warning (VDMP) | 0.65% | 75 | Warning |
| Visa | Standard (VDMP) | 0.9% | 100 | Monitored |
| Visa | Excessive (VDMP) | 1.8% | 1,000 | Critical |
| Mastercard | Early Warning (MCCMP) | 0.5% | — | Warning |
| Mastercard | Standard (MCCMP) | 1.0% | 100 | Monitored |
| Mastercard | Excessive (MCCMP) | 1.5% | 300 | Critical |
What Happens When You Breach a Threshold?
- Fines begin immediately — ranging from $25–$100 per chargeback, escalating monthly you remain in the program.
- Acquirer notification — your payment processor is alerted and may place an additional rolling reserve on your account (typically 5–15% of volume).
- Account review or termination — at excessive levels, your acquirer may terminate your merchant account entirely.
- MATCH/TMF listing — if terminated for excessive chargebacks, you may be placed on the MATCH (Terminated Merchant File) list, making it very difficult to obtain future processing.
What Causes High Chargebacks?
- Friendly fraud — cardholders dispute legitimate purchases, often after receiving the goods.
- Poor customer service — customers can't reach the merchant so they dispute via their bank instead.
- Unclear billing descriptors — customers don't recognize the charge on their statement.
- Subscription misunderstandings — customers forget they subscribed or didn't see cancellation terms clearly.
- Delivery failures — products lost in shipping result in legitimate disputes.
- Fraud transactions — genuine fraudulent card use that results in chargebacks.
How to Reduce Your Chargeback Ratio
- Use clear billing descriptors — make sure your business name appears exactly as customers expect on card statements.
- Improve customer service accessibility — a simple phone number or live chat can prevent a dispute from becoming a chargeback.
- Send order confirmation and shipping emails — communication reduces "I don't recognise this" disputes.
- Deploy chargeback alert services — tools like Ethoca or Verifi notify you of incoming disputes before they become chargebacks.
- Fight illegitimate chargebacks — maintain proper documentation (transaction logs, delivery confirmations, signed agreements) to win representments.
- Use 3DS2 authentication — shifts liability away from the merchant on authenticated transactions.
💡 QuadraPay Tip: If your ratio is above 0.7%, you need to act now — not when you hit 1.0%. QuadraPay can help you access chargeback alert services, find acquirers with higher risk tolerance, and structure your account to protect your processing.

Frequently Asked Questions
What chargeback ratio is considered safe?
Generally, a ratio below 0.5% is considered healthy and low-risk. Between 0.5%–0.9% you're in a warning zone and should take action. Above 0.9% (Visa) or 1.0% (Mastercard) you're in a formal monitoring program and facing fines and potential account termination.
How are chargebacks different from refunds?
A refund is initiated by the merchant and returned voluntarily to the customer. A chargeback is initiated by the customer's bank, forcibly taken from the merchant, and comes with an additional chargeback fee ($15–$100). Refunds do not count toward your chargeback ratio — chargebacks do. This is why proactively offering refunds can actually protect your ratio.
Can I get a merchant account with a high chargeback ratio?
Yes, but you need a specialist. Standard acquirers will decline merchants above 1% ratios. However, high-risk acquirers — accessible through consultants like QuadraPay — work with merchants in elevated chargeback categories, often with conditions such as rolling reserves and higher processing rates. If you have a MATCH listing, specialist offshore acquirers may still be able to help.
What is the MATCH list and how do I avoid it?
MATCH (Member Alert to Control High-Risk Merchants) is a database maintained by Mastercard. Acquirers report merchants when they terminate their account due to excessive chargebacks, fraud, or compliance violations. Being on the MATCH list makes it very difficult to get a new merchant account. The best way to avoid it is to keep your chargeback ratio below thresholds and communicate openly with your processor if issues arise — never let an account get terminated without prior discussion.
Do chargebacks affect my processing rate?
Yes, significantly. An elevated chargeback ratio signals risk to processors and acquirers, which often results in higher MDR rates, additional reserve requirements, and more restrictive processing terms. Keeping your ratio low is one of the most effective ways to negotiate better processing rates over time.
How quickly can I recover from a high chargeback ratio?
Typically 3–6 months of sustained improvement is needed to exit a monitoring program. The key is addressing root causes immediately — improve customer communication, deploy chargeback alerts, and fight illegitimate disputes. Your processor will review your ratio monthly once you're in a program, so every month of improvement counts.
