Card Processing Fee Calculator
Card fees look small on each sale: a few percent and a few cents. Added up over a year, they can be one of a restaurant's biggest costs after food, labor and rent. Enter your card sales and your rates to see your real annual cost, your effective rate, how much of your profit it takes, and what a competing quote would save.
Uses one blended rate. Real statements often charge different rates by card type (debit, rewards, business cards) and for keyed-in or online sales, so use your statement’s total fees to check the effective rate. Estimates only. This calculator is for educational purposes and is not financial, tax or legal advice.
Your effective rate is the number to compare
Processors quote rates in different ways: a flat percentage, a percentage plus a few cents, or "interchange plus" pricing that passes through the card networks' costs plus a markup. The only fair way to compare is your effective rate: every fee you paid in a month divided by your card sales that month. It's on every statement if you add it up.
The per-transaction fee matters more than it looks for a coffee shop or quick-service restaurant. On a $6 sale, 15 cents is another 2.5%.
A worked example
$60,000 a month in card sales at an average of $35 is about 1,714 transactions. At 2.9% plus 15 cents and $30 a month in fees, that's $1,740 + $257.14 + $30 = $2,027.14 a month, an effective rate of 3.38%, or $24,326 a year. At a 5% profit margin the restaurant makes $3,000 a month, so card fees take an amount equal to about two thirds of its profit. A quote of 2.6% plus 10 cents with no monthly fee would save about $3,549 a year.
What you can do about it
- Get competing quotes and compare effective rates, not headline rates.
- Ask about every monthly fee on your statement: statement fees, PCI fees, terminal rentals and minimums add up.
- Build the cost into your prices. The calculator shows the price increase that would cover your fees.
- Surcharges and cash discounts are another option, but the rules depend on your state and the card networks. Check them, and tell customers clearly, before you add one.
Card fees are a common pain point: in the National Restaurant Association's 2026 State of the Industry research, more than 80% of operators said they feel significant strain from credit and debit card processing fees (National Restaurant Association).

Frequently Asked Questions
How do I calculate my effective card processing rate?
Add up every fee on a month’s processor statement, including per-transaction and monthly fees, and divide by your card sales for that month. That one number lets you compare any two processors fairly.
How much do card fees cost a restaurant?
It depends on card sales, the average check and the rates. $60,000 a month in card sales at an effective rate around 3.4% is about $24,000 a year. The calculator works it out for your numbers.
How much should I raise prices to cover card fees?
Divide your effective rate by one minus that rate. At a 3.38% effective rate, prices about 3.5% higher cover the fees on card sales.
Can I add a surcharge for card payments?
Rules on surcharges and cash discounts depend on your state and the card networks, and some states restrict them. Check the current rules and tell customers clearly before you add one.
