Where does your portfolio sit against VAMP?

Visa measures your whole book: fraud reports plus disputes, divided by settled transactions, counted in events. Put in your own volumes and see your position against the 0.5% Above Standard and 0.7% Excessive lines — and how far confusion-dispute reduction moves it.

How this is calculated

The ratio is (fraud reports + disputes) ÷ settled transactions, in events — a $9.99 dispute counts exactly as much as a $5,000 one. Acquirer portfolio thresholds shown are 0.5% Above Standard and 0.7% Excessive; merchant-level monitoring runs separately at 1.5%. Program thresholds change — verify against current Visa documentation before relying on them.

The ladder reduces disputes (TC15) only. That is deliberate and conservative: a cardholder who recognizes a charge also doesn't report it as fraud, so recognition pressure on TC40 is real upside the model leaves out.

RDR and CDRN resolve disputes after they are raised — the fee is paid, and TC40 still counts where fraud was claimed. Preventing the dispute at the descriptor removes the event from the numerator entirely. Both approaches coexist; they are not substitutes.

This is an arithmetic model of your own inputs, not a performance guarantee, a forecast, or a compliance determination. Actual program standing depends on Visa's calculations, enforcement timelines and your full portfolio mix.
