How to Read a Card Processing Statement
Reconcile turnover and card-processing charges and calculate an effective rate without hiding one-off fees.
A statement can reveal the effective cost actually paid, but only when charges and periods are reconciled carefully.
Confirm the period
Match the statement dates to the settlement or sales report. Do not divide one month's fees by another month's turnover, and distinguish gross processed value from refunds or reversals.
Group charges
Separate percentage processing, fixed transaction fees, authorisations, terminal rental, PCI or compliance charges, gateway subscriptions, refunds, chargebacks and adjustments. Annual charges should not be mistaken for normal monthly costs.
Calculate an effective rate
Divide the relevant total fees by the relevant card turnover and multiply by 100. Retain the cash amount as well: identical effective rates can imply very different costs at different volumes.
Reconcile a worked example
If £212 of charges relates to £12,000 turnover, the illustrated effective rate is 1.77%. If £30 is an annual charge unrelated to that month, show both the statement total and an adjusted recurring view rather than silently excluding it.
Questions to raise
Ask the provider about unfamiliar codes, changes in card mix, minimum charges and fees triggered by a refund or disputed payment. Never upload an unredacted merchant statement to a public tool.
