Visa dropped the merchant “Excessive” VAMP ratio from 2.2% to 1.5% on April 1, 2026. A merchant sitting comfortably in March can be in violation in April on the exact same volume. This gate computes your Visa and Mastercard ratios from your own numbers against the thresholds you confirm, and tells you honestly where you stand — then scores prevention separately, because winning a dispute doesn’t lower a counted chargeback.

01.The Problem

The line moved, and most merchants can’t see their own number.

2.2% → 1.5%

Visa's merchant Excessive VAMP ratio, effective April 1, 2026 — a ~32% cut in allowable dispute volume overnight, on the exact same transactions.

counts twice

One friendly-fraud transaction can hit your VAMP ratio as both a TC40 fraud report and a TC15 dispute — so the acquirer's number runs higher than your dashboard.

3 clean months

what it takes to exit a monitoring program once you're over. A single spike resets the clock — which is why catching an approaching ratio early is everything.

Most merchants can’t see their own network number until the acquirer sends a warning — and most chargeback tools quietly imply that fighting disputes fixes the ratio. It doesn’t. A won representment never removes a counted chargeback.

02.See It Work

Enter one account’s month and watch two honest reads.

The ratio position is the verdict; prevention is a separate read. Set every control to “in place” and watch the ratio still read OVER THE LINE — that’s the honest core, not a bug.

Two independent reads. The ratio is math against a hard line and is the verdict; prevention is a separate read that names what to fix. Notice you can set every control to “in place” (prevention HARDENED) and the ratio still reads OVER THE LINE — because winning a dispute doesn’t lower a counted chargeback. Thresholds shown are the verified April 1, 2026 defaults; confirm yours against your acquirer. Grades an account’s numbers, not people. Not legal or payment advice.

03.The Runnable Engine

One command, every merchant account you run, an honest read.

The shipped three-MID sample, run verbatim. The Main storefront is the teaching case: prevention scored a perfect 100 / HARDENED, and it’s still OVER THE LINE on a 1.58% Visa ratio. Good controls, still over the line.

04.The Standard

Two ratios for the verdict. One scorecard for the fix.

Visa VAMP ratio

(TC40 fraud + TC15 disputes) ÷ card-not-present settled transactions. CNP only, and one transaction can count twice — so it runs higher than your dashboard.

Mastercard ECP ratio

Current-month chargebacks ÷ prior-month transactions, chargebacks only. Computed separately, because the formulas differ and a blend hides your real exposure.

The monitoring floor

Below 1,500 combined events (Visa) or 100 disputes (Mastercard), the network isn't counting you yet — flagged 'below floor,' a warning, not an all-clear.

The prevention scorecard

Six weighted controls roll up to HARDENED / SOFT / EXPOSED and name the fix-first move — a separate read that never averages into the verdict.

The ratio is the verdict

Your position against a hard threshold is computed math, not a judgment call. HEADROOM, APPROACHING, or OVER THE LINE — worst network wins, monitoring floor respected.

Prevention is a separate read

Six weighted controls roll up on their own and name what to fix. It never averages into the verdict — because it can't remove a counted event, only slow the next one.

Your thresholds, your numbers

Ships the verified April-2026 defaults, but every threshold is a cell you confirm against your acquirer. It computes against what you enter, so it stays right when the line moves again.

05.What This Is — And Isn't

A ratio read, not a dispute service.

What it is
  • A deterministic monthly read of where your ratio sits against the line.
  • A separate, honest prevention scorecard that names the fix-first move.
  • Built to stay correct when the thresholds change — you edit four cells.
  • Offline — engine, workbook, and demo agree to the number.
What it isn’t
  • Not a dispute-fighting or representment service — it files and sends nothing.
  • Not a live processor integration — you bring the numbers from your statement.
  • Not legal or payment-compliance advice, or a guarantee against enforcement.
  • Not a margin or fraud-loss model — it reads ratio position, not P&L.

Not legal or payment-compliance advice. This grades a merchant account’s own numbers, not people. The card-network thresholds it ships with are dated, regional, and change by bulletin — you confirm yours against your acquirer statement and the current Visa and Mastercard bulletins before acting. It reads no live processor data, files nothing, contacts no acquirer, and moves no money.

06.Who It's For

Merchants who just watched the line drop to 1.5%.

CNP e-commerce and subscription merchants unsure where they now stand
Operators running several MIDs who need one book-level read + the account to work first
High-risk verticals (nutra, gaming, telemedicine, ticketing) where a program can cost the MID
Finance and ops owners who want the honest math monthly, not a flattering dashboard
Merchants heading into an acquirer review who want their real number first
Anyone told 'fight your disputes' who suspects that isn't moving the ratio
08.Common Questions

The questions merchants actually ask before they buy.

No. It computes where your ratio sits against the thresholds you confirm and tells you honestly whether you're in headroom, approaching, or over the line — and it names what to fix first. It files nothing, contacts no acquirer, and moves no money. The hard truth it's built around: winning a representment does not lower a counted chargeback. The event still counts toward your ratio. Only pre-dispute deflection (RDR / Compelling Evidence 3.0) and proactive refunds remove events from the count, which is exactly why the tool separates your ratio position from your prevention posture instead of blending them.
