Cost examples and choosing a best-fit processor

Worked cost examples, effective-rate arithmetic and checklists for comparing processor quotes.

Knowing how fees are built is only half the job. The other half is putting your own sales mix into numbers: how many transactions a month, what average ticket, how much is Interac debit, how much is credit, how much is online, and which monthly fixed fees come on top.

This section works through those numbers. You will find worked monthly estimates for different kinds of businesses, a step-by-step method for calculating your effective rate from a monthly statement, the arithmetic of renting versus buying a terminal, what online gateways and POS software add, a method for checking whether switching processors pays for itself, and a quote-comparison checklist.

There are no rankings here and no provider scores. A processor that fits a seasonal food truck can be the wrong fit for a dental clinic, and the reverse. The aim is that you can put two or three quotes side by side and see the full monthly cost of each in dollars. Begin with the card processing cost estimates and use the monthly cost estimator with your own figures.
