How the math works: interchange is set by the card networks (Visa, Mastercard, and others) and varies by card type and how the card is accepted, so your real interchange-plus cost depends on your actual card mix. The interchange field above is an editable estimate. Flat-rate defaults to a common online rate of 2.9% + $0.30 - enter your own rate to compare. Figures are estimates only, exclude any monthly platform fees on either side, and are not a quote.
