Mastercard ECM vs Visa VAMP
Side-by-side comparison of the two card network monitoring programs that most subscription apps will encounter. Thresholds, formulas, volume floors, exit criteria, severity, and remediation playbooks — verified against current network documentation as of May 2026.
ECM / ECP
Excessive Chargeback Merchant / Excessive Chargeback Program. Long-standing chargeback-only monitoring.
VAMP
Visa Acquirer Monitoring Program. Combined fraud + dispute ratio. Replaced VDMP and VFMP.
The TL;DR
VAMP and ECM are not redundant and are not interchangeable. They measure different things, on different networks, with different volume floors. A subscription app in trouble on Visa is often in trouble on Mastercard too, but the timing of enrollment and the precise remediation track differ. The most important practical difference: VAMP has no volume floor and ECM does. Small merchants typically cross VAMP first; large merchants with concentrated chargebacks may hit ECM faster.
Full side-by-side
| Attribute | Mastercard ECM | Visa VAMP |
|---|---|---|
| Network | Mastercard | Visa |
| What it measures | Chargebacks ÷ transactions | (Fraud + chargebacks) ÷ settled transactions |
| Fraud reports counted? | No (separate program: EFM) | Yes (TC40 reports) |
| Entry threshold (lower tier) | ECP: 1.00% chargeback ratio + 100 chargebacks/mo | Above-Standard: 0.30% combined ratio |
| Entry threshold (upper tier) | ECM: 1.50% chargeback ratio + 100 chargebacks/mo | Excessive: 0.90% combined ratio |
| Volume floor | 100 chargebacks/month — protects smaller merchants | None — applies at any volume |
| Lower-tier consequences | Acquirer monitoring + remediation plan | Acquirer monitoring + remediation plan |
| Upper-tier consequences | Per-dispute assessments + formal enrollment | Per-dispute assessments + offboarding risk |
| Exit window | Below threshold for 3 consecutive months | Below threshold for 3 consecutive months |
| Effective | Long-standing (years) | April 1, 2025 (replaced VDMP and VFMP) |
| Nuclear outcome | MATCH list (5-year ban) | Acquirer offboarding + Visa disqualification |
| Measurement cadence | Monthly | Monthly |
| Reporting transparency to merchants | Through acquirer; limited direct visibility | Currently through acquirer; Visa has signaled direct merchant reports may come in 2026 |
Where the structural difference matters most
For small subscription apps (≤ 50K monthly transactions)
VAMP is almost always the more pressing program. A small merchant with ~5,000 transactions and just 16 combined fraud-plus-disputes is at 0.32% — above the VAMP Above-Standard threshold — while having nowhere near the 100-chargeback ECM floor. Small merchants can be fully under VAMP enforcement while ECM is functionally inert.
For large subscription apps (≥ 500K monthly transactions)
Both programs can trip near-simultaneously, but ECM's percentage threshold (1.50% for full ECM) is higher than VAMP's 0.90% Excessive — so VAMP typically hits Excessive first. ECM full enrollment usually arrives a few weeks behind because the chargeback ratio takes longer to push to 1.50%.
For subscription apps with concentrated fraud (high TC40, moderate disputes)
VAMP punishes fraud more directly than ECM. ECM only measures chargebacks; fraud transactions that didn't crystallize into chargebacks don't count toward ECM ratio. VAMP combines both. An app with elevated card-testing or stolen-card fraud will see VAMP climb faster than ECM.
For subscription apps with concentrated friendly fraud (high disputes, low fraud)
ECM and VAMP move at similar rates here because disputes count toward both. The remediation work overlaps almost entirely: better billing descriptor, clearer renewal notifications, self-serve refund flow, Ethoca and Verifi dispute interception.
Severity comparison
| Outcome | ECM path | VAMP path |
|---|---|---|
| Early warning | ECP enrollment at 1.00% + 100/mo | Above-Standard at 0.30% combined |
| Full program enrollment | ECM at 1.50% + 100/mo | Excessive at 0.90% combined |
| Per-dispute fines | Yes, in ECM | Yes, in Excessive |
| Direct offboarding risk | Possible after sustained ECM | Possible after sustained Excessive |
| MATCH placement | Yes — reason code 12 (excessive chargebacks) | No direct MATCH placement, but offboarding from VAMP-Excessive can trigger MATCH via the acquirer |
| Cross-network impact | MATCH is queried by Visa during onboarding | VAMP enforcement is Visa-only but acquirers often share risk signals informally |
Real-world scenarios
Scenario A: Series A subscription app, 8K monthly transactions, 40 chargebacks, 12 TC40 fraud reports
Mastercard ECM: 40 ÷ 8,000 = 0.50% chargeback ratio. Below the 1.00% ECP threshold. But more importantly, 40 chargebacks is below the 100-chargeback volume floor — ECM cannot enroll. Safe on Mastercard.
Visa VAMP: (12 + 40) ÷ 8,000 = 0.65% combined ratio. Above the 0.30% Above-Standard threshold. Acquirer monitoring active. ~25 basis points below Excessive (0.90%).
Practical move: Focus rescue work on VAMP. ECM is structurally inert at this volume.
Scenario B: Series B subscription app, 200K monthly transactions, 1,900 chargebacks, 800 TC40 fraud reports
Mastercard ECM: 1,900 ÷ 200,000 = 0.95% chargeback ratio with well over 100 chargebacks. Approaching ECP at 1.00%; full ECM still well off at 1.50%.
Visa VAMP: (800 + 1,900) ÷ 200,000 = 1.35% combined ratio. Above Excessive (0.90%) by 45 basis points. Per-dispute assessments active.
Practical move: VAMP Excessive is the urgent fire. Structural fixes will pull ECM back from the 1.00% ECP threshold simultaneously.
Scenario C: Series C subscription app, 1M monthly transactions, 18,000 chargebacks, 2,000 TC40 fraud reports
Mastercard ECM: 18,000 ÷ 1,000,000 = 1.80% chargeback ratio. Squarely above ECM threshold of 1.50%. Per-dispute assessments active. Real MATCH risk if not remediated.
Visa VAMP: (2,000 + 18,000) ÷ 1,000,000 = 2.00% combined ratio. Far above Excessive (0.90%). Severe enforcement on both programs simultaneously.
Practical move: Both programs are full-enforcement. The 90-day rescue program runs ECM and VAMP exit work in parallel because the structural fixes overlap.
