What does U.S. card processing cost on $100,000 in sales? On card-present merchant volume, the percentage is only half the bill. A fixed cents-per-sale fee changes the total as soon as the average ticket changes. Two stores that both process $100,000 can owe hundreds of dollars more or less than each other on the same quoted rate.

The worked examples below use Counter Club’s published in-person sample of 2.50% plus $0.10 per transaction, with $0 in monthly and PCI fees. Sample pricing applies to new accounts applying directly. Pricing is subject to underwriting, MCC and the merchant agreement; rates may differ and are subject to change. The live schedule is on pricing.

Square’s our-fees page, retrieved 2026-09-11, lists tap at 2.6% plus 15 cents. On $100,000 that is $2,600 plus 15 cents times your transaction count. A thousand $100 sales add $150 in fixed fees. Ten thousand $10 sales add $1,500. Recheck Square’s page because those figures change.

This is not your quote. Use the rate and fixed fee from your own merchant agreement or statement. The schedules below illustrate the formula and are not a general market rate.

The two lines that make the $100,000 bill

Percentage cost: 2.50% of $100,000 is $2,500. That line does not care how many baskets made the volume.

Per-transaction cost: $0.10 times the number of card sales. A $10 average ticket is 10,000 sales, so $1,000. A $50 average ticket is 2,000 sales, so $200. Same volume, $800 difference.

Add them. Ignore hardware and chargebacks for this page. Those are real costs and they belong in what a POS system costs, not in this $100,000 card-fee example.

Using 2.50% plus $0.10, and no monthly fees:

  • $10 average ticket: 10,000 sales. $2,500 + $1,000 = $3,500. Effective rate 3.50%.
  • $25 average ticket: 4,000 sales. $2,500 + $400 = $2,900. Effective rate 2.90%.
  • $50 average ticket: 2,000 sales. $2,500 + $200 = $2,700. Effective rate 2.70%.
  • $100 average ticket: 1,000 sales. $2,500 + $100 = $2,600. Effective rate 2.60%.

A convenience counter lives near the top of that list. A liquor basket lives nearer the bottom. That is why a c-store and a package store should not compare headline percentages.

If the same $100,000 were all keyed or online at the published 2.90% plus $0.25 sample, the percentage line becomes $2,900 and each sale costs a quarter. At a $25 ticket that is 4,000 sales: $2,900 + $1,000 = $3,900, or 3.90% effective. Keyed volume is expensive. Take the card in person when you can.

What a monthly fee does to the same $100,000

A $25 monthly minimum that actually bills, or a $25 statement fee, adds 0.025 percentage points on $100,000. It barely moves a six-figure month. It wrecks a $8,000 month. That is why small stores feel “junk fees” and larger stores shrug.

Counter Club’s published sample lists a $0 monthly fee, and a monthly minimum of $0 to $25 that is waived once discount charges exceed $25. If you are comparing a quote that still has a $25 statement fee, add it. Do not assume it is in the percentage.

Chargebacks are $25 per dispute and $25 per representment on that same published schedule. They are not in the table above because they are not a function of $100,000. They are a function of disputes.

How to get the number for your store, not this example

Pull one full month. Use card volume, not total sales. Use card transaction count, not all tenders. Add every processing line: percentage, per-item, monthly, PCI, batch, gateway. Divide by card volume. That is your effective rate.

Our processing fee calculator does the same math with numbers you type. It will not paste our schedule in for you. If you want a comparison point, use the sample rates on pricing and the ticket sizes above.

A $100,000 question is also a mix question. Rewards cards, keyed sales, and card-not-present volume land in different buckets. The examples assume every sale qualified for the quoted card-present rate. Downgrades make the real bill higher. Taking the card, settling daily, and capturing AVS on keyed sales are the usual fixes, described on what processing fees cover.

If you want someone to run the $100,000 case on your actual statement, send one month. Bring the transaction count, not only the volume.

Frequently asked questions

Is $2,500 the POS charge on $100,000? Only the percentage line, and only at 2.50% with no extras. The per-sale fee and any monthly lines still have to be added.

Do cash sales count in the $100,000? Not for this question. POS card charges are assessed on card volume. Dual pricing changes who pays, which is a different page: cash discount and dual pricing.

What if my volume is $100,000 a year, not a month? Divide. $100,000 a year is about $8,333 a month. Fixed fees then matter much more than they do in the table above.

Can I make the customer pay it? Sometimes, inside network and state rules. That is a surcharge or dual-price decision, not a $100,000 arithmetic decision. Start with whether charging the customer 3% is illegal.

Will my quote match these numbers? Only if your rate, ticket mix, and monthly fees match the assumptions. Pricing is subject to underwriting, MCC and the merchant agreement; rates may differ and are subject to change.
