Total processing fees divided by total card sales equals effective processing rate. Use fees and sales from the same month. Do not mix deposits from one period with fees from another.
Effective rate formula
How to calculate your effective credit card processing rate.
Your effective processing rate is calculated by dividing total processing fees by total card sales for the same statement period. For example, if a business paid $900 in fees on $30,000 in card sales, the effective rate is 3.00%. The number is useful, but it does not prove whether pricing is fair without reviewing the underlying fees and payment mix.
Review-first boundary
HMG reviews actual statements and payment workflows before making claims about savings, switching, or processor fit.
Useful input
A recent merchant statement and a short note about how customers pay today usually gives the review enough context to start.
Plain-English guide
What to review before making a payment processor decision.
Use this as a practical starting point. It is not a guarantee that a different provider is better.
The rate usually includes interchange, assessments, processor markup, transaction fees, gateway fees, monthly fees, and miscellaneous charges.
A higher effective rate may be reasonable for businesses with small tickets, keyed transactions, rewards cards, card-not-present payments, or higher-risk payment patterns. A lower rate can still hide bad contract terms or poor support.

FAQ
Common questions before requesting a review.
What is a good effective processing rate?
There is no universal number. It depends on business type, transaction size, card mix, and payment method mix.
Is effective rate the same as my quoted rate?
No. Quoted rates often show only part of the cost. Effective rate shows the all-in cost for the period.
Can HMG tell me if my effective rate is fair?
HMG can review the full statement and explain whether the rate appears reasonable in context.
