Credit Card Processing Fee Calculator

Enter one sale amount to compare what Stripe, Square (online and in person), PayPal, Venmo business and a processor of your choice would charge and what you keep. Add your monthly number of sales to project a month and a year of fees, or switch to reverse mode to find the price that nets you an exact amount. Every rate is an editable default taken from the vendor's standard published US pricing as of September 2026. Fees change and vary by country, account and product, so check the linked pricing page before relying on a number. Everything runs in your browser. Nothing you type is sent to We.Inc or anyone else.

How it works

  1. Enter the sale amount. Each row shows the percentage fee, the fixed fee, the total fee, the effective rate and what you keep.
  2. Enter how many sales like this you make a month to see monthly and yearly fees for each processor.
  3. Edit any rate in the table. Defaults are each vendor's standard published US rate as we understand it in September 2026, with a link to its pricing page.
  4. Fill in the custom row with a quote you have received or your current statement's rate, for example an interchange-plus deal.
  5. Turn on reverse mode and enter the amount you want to receive. Each row shows the price you would need to charge through that processor.

Worked example: a $65 order, 300 times a month

At 2.9% plus $0.30 a $65 online order costs $2.19 in fees, an effective rate of 3.37%. At 300 orders a month that is $657 a month and $7,884 a year. The same order through PayPal goods and services at 3.49% plus $0.49 costs $2.76, or $828 a month.

In person on a card reader at 2.6% plus $0.15, the same $65 costs $1.84. Knowing which of your sales are online and which are in person lets you project fees accurately.

Small sales and the fixed fee

On a $4 coffee at 2.6% plus $0.15 the fee is $0.25, an effective rate of 6.3%. The percentage is the same as on a large sale, but the fixed fee is spread over less money. Businesses with many small sales should compare the fixed fee first.

Tips

Frequently asked questions

How are credit card processing fees calculated?

Most flat-rate processors charge a percentage of the sale plus a fixed amount per transaction. At 2.9% plus $0.30, a $40 sale costs $1.16 plus $0.30, or $1.46. This calculator applies that formula for each processor using the rates you see in the table.

What rates does the calculator use by default?

Standard published US rates as we understand them in September 2026: Stripe online cards 2.9% plus $0.30; Square online 3.3% plus $0.30 (Free plan; 2.9% plus $0.30 on paid plans) and in person 2.6% plus $0.15; PayPal goods and services 3.49% plus $0.49; Venmo business 1.9% plus $0.10. Each is editable and linked to the vendor's pricing page.

How do I find the price that nets me a set amount?

Add the fixed fee to the amount you want and divide by one minus the percentage. To net $100 at 2.9% plus $0.30 you charge $103.30. Reverse mode shows this for every processor at once.

Which processor is cheapest?

On the default rates it depends on the sale size and whether the card is present. The table sorts nothing for you and highlights the lowest fee for the amount you entered, but fees are only part of the choice: payout speed, features and where your customers already pay matter too.

Does this include interchange-plus pricing?

Not directly, because interchange varies by card type. Use the custom row with your average effective rate, or the percentage and fixed fee from your quote.

Which processor does We.Inc use?

This calculator does not recommend or assume any processor. It compares standard public rates so you can make your own choice.

Is this calculator free?

Yes, with no signup, and nothing you enter leaves your browser.
