Volume by payment method

Volume by payment method measures the total transaction value processed through each payment method type. It quantifies the financial weight of each method beyond simple transaction counts, revealing which methods carry the most revenue and where cost optimisation will have the greatest impact.

What is volume by payment method?

Volume by payment method goes beyond payment method distribution (which counts transactions) to measure the monetary value flowing through each method. A payment method may account for only 15% of transactions but 40% of volume if it is preferred for higher-value purchases.

This distinction matters because processing fees, success rates, and risk profiles are typically proportional to transaction value rather than count. Optimising the payment path for your highest-volume method delivers a larger absolute saving than optimising a method with many small transactions.

Correlating volume by method with processing fees and charge success rate helps steer customers towards methods that balance cost, conversion, and risk. A method with low fees but a poor success rate may cost more in lost revenue than it saves in processing charges.

How to calculate volume by payment method

Volume Share = (Total Value via Method / Total Payment Volume) x 100

For example, if credit cards process 500,000 pounds of a total 800,000 in GPV, the credit card volume share is 62.5%. Compare this to the transaction count share: if credit cards account for 70% of transactions, the average credit card transaction is smaller than the average for other methods.

Track volume share trends monthly. A significant shift may indicate changing customer preferences, checkout changes, or the impact of newly added payment methods.

How to optimise volume by payment method

  1. 1

    Target high-volume methods for fee negotiation

    Focus fee negotiations on the methods that carry the most volume. A 0.1% reduction on a method processing 60% of volume delivers far more savings than the same reduction on a 5% method.

  2. 2

    Match payment methods to transaction types

    Promote bank transfers or direct debits for high-value recurring payments where card fees are proportionally costly. Reserve card acceptance for situations where the convenience justifies the higher processing cost.

  3. 3

    Monitor success rates by method and value

    High-value transactions may have different success rates by method. If bank transfers succeed at 99% for large amounts but cards at 92%, actively steering large transactions to bank transfer recovers significant revenue.

  4. 4

    Track method adoption for new offerings

    When adding new payment methods, measure volume uptake rather than just transaction count. A method that attracts high-value transactions contributes more to the business than one with many small payments.

Optimise where your revenue flows

Build a metric tree that connects volume by payment method to processing fees, success rates, and charge success rate so you can route revenue through the most cost-effective channels.
