Visa VAMP Combined Ratio
VAMP measures fraud + non-fraud disputes against settled transactions as a single combined ratio. Effective since April 1, 2025.

Enter values to see tier
VAMP combined ratio = (fraud + chargebacks) ÷ settled transactions.
| Tier | Threshold | What it means |
|---|---|---|
| Below standard | < 0.30% | No program enforcement |
| Above Standard | ≥ 0.30% | Acquirer monitoring + remediation plan required |
| Excessive | ≥ 0.90% | Per-dispute assessments + offboarding risk |
Exit either tier: combined ratio below threshold for 3 consecutive calendar months.
Mastercard ECM Chargeback Ratio
ECM measures chargeback count against transaction volume. Requires both a percentage breach AND 100+ absolute chargebacks in a calendar month.

Enter values to see tier
ECM chargeback ratio = chargeback count ÷ transaction count. Floor: 100 chargebacks in a single calendar month.
| Tier | Ratio | Absolute count | What it means |
|---|---|---|---|
| Below | < 1.00% | any | No program enforcement |
| ECP (Early Warning) | ≥ 1.00% | ≥ 100 | Acquirer monitoring begins |
| ECM (Full) | ≥ 1.50% | ≥ 100 | Formal program enrollment + per-dispute assessments |
Exit either tier: ratio + count below thresholds for 3 consecutive calendar months.
About the math. These calculators use the published card network formulas. Outputs are estimates of your current-month position — the official acquirer measurement looks at multi-month rolling windows and includes additional fields (e.g., TC40 fraud reports for VAMP keep arriving from issuing banks for up to 30 days after the fraud occurred). Treat the calculator output as a leading indicator, not as the acquirer's official measurement.
When to act on the result
- 1Below threshold: No action required. Keep monitoring monthly — the ratios move faster than most teams expect.
- 2VAMP Above-Standard (0.30%+) or ECP (1.00%+): Optimal window. Acquirer hasn't escalated yet, and you have the widest solution space. Deploy structural fixes — Stripe Radar rule rebuild, dynamic 3DS gating, Ethoca and Verifi integration.
- 3VAMP Excessive (0.90%+) or ECM (1.50%+): Urgent. The acquirer is escalating, processor risk teams are reviewing, and the window before per-dispute assessments or offboarding is narrow. Engage rescue work immediately.
