Looking for the cheapest way to take card payments? This credit card processing fee calculator compares seven processors side by side so you can see who takes the smallest bite out of every sale.

We ran the numbers on the point-of-sale systems most Pittsburgh small businesses rely on, and the gap in in-person credit card processing fees is bigger than most owners realize. Which system actually saves you money comes down almost entirely to your average ticket size.

What we found

If you process a high volume of low-dollar items, say an average sale around $5, flat per-transaction fees quietly eat into your margins. On $10,000 in annual revenue (roughly 2,000 transactions), Square runs about $560 while a flat-rate processor like GoDaddy POS comes in around $230. That is about $330 saved on just $10K, and as your sales grow the gap widens into thousands of dollars a year. For a busy, low-ticket shop, simply changing who processes your orders can keep that money in your pocket.

Support local. Shop local. Keep Pittsburgh strong.

How the processing fee calculator works

Type in your average ticket size and monthly card volume, and the tool applies each processor’s percentage rate plus its per-transaction flat fee. At a $35 ticket the flat fee barely registers; at a $5 sticker it can double your effective rate, which is why the ranking can flip depending on what you sell.

Frequently asked questions

How are credit card processing fees calculated?

Most processors charge a percentage of each sale plus a fixed flat fee per transaction. Your effective rate is the total of both divided by the sale amount.

Why do flat fees hurt small purchases more?

A 30-cent flat fee is tiny on a $35 sale but large on a $5 one. The smaller your average ticket, the more those per-transaction fees raise your real cost.

Which card processor is cheapest?

It depends on your ticket size and volume. The calculator ranks seven processors for your specific numbers, cheapest first, so there is no single winner for every business.

What is an effective processing rate?

It is the share of a sale you actually lose to fees once both the percentage and the flat fee are included — the number worth comparing across processors.

How can a small business lower processing fees?

Match your processor to your average ticket, encourage larger baskets, and review your statements; the best processor for a $5 sticker shop differs from one selling $80 items.
