Start with total effective cost
- Divide total processing-related fees by total card volume to understand the monthly effective rate.
- Compare multiple months when seasonality or card mix changes.
- Separate card-processing cost from unrelated software or hardware charges where possible.
- Do not assume the lowest advertised percentage produces the lowest total cost.
Understand the main fee categories
- Interchange varies by card type, transaction method and qualification.
- Card-network assessments and other network fees are separate from processor markup.
- Processor markup may be expressed as basis points, per-item fees or bundled pricing.
- Gateway, PCI, statement, batch, device and other fees may also apply.
Watch card mix and transaction method
- Rewards, commercial and international cards can carry different costs.
- Card-not-present and keyed transactions may qualify differently from card-present payments.
- Average ticket size affects how per-item fees influence total cost.
- Commercial-card data can matter for eligible B2B transactions.
Compare statements line by line
- Identify processor-controlled markup separately from pass-through network and interchange costs.
- Look for monthly minimums, annual fees, PCI fees and non-qualification charges.
- Check whether gateway or software costs are billed separately.
- Review chargeback and retrieval fees if disputes are material.
Use the comparison to find the real opportunity
- Some merchants need lower processor markup.
- Others have avoidable interchange downgrades or inefficient transaction methods.
- Technology changes may matter more than a pricing change.
- A statement review should identify the source of cost before recommending a switch.
