Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Processing fee | Sale plus fee |
|---|---|---|
| $1,000 · 2.9% | $29.00 | $1,029.00 |
| $50 · 3.5% | $1.75 | $51.75 |
| $25,000 · 1.8% | $450.00 | $25,450.00 |
| $300 · 2.6% | $7.80 | $307.80 |
How This Calculator Works
Enter the sale amount and the processing fee percentage. The calculator multiplies the two to find the processing fee. The merchant's net is the sale minus the fee; the figure shown as total here is the sale plus the fee, the cost of building the fee into the price.
The Formula
Percentage Add-On
Rate is the tax or tip percentage applied to the amount
Worked Example
On a $1,000 sale at a 2.9% processing rate, the processing fee is $29. The merchant receives $971 of the original sale, or alternatively could quote $1,029 to pass the fee on as a surcharge.
Key Insight
Many processors also add a flat per-transaction fee — often around $0.30 — that this calculator does not model. On small transactions that flat fee can dwarf the percentage portion, so factor it in for low-ticket sales.
Frequently Asked Questions
What is a processing fee?
It is the fee a payment processor charges to handle a card transaction, usually a percentage of the sale plus a small flat amount per transaction.
What rate is typical?
Common rates run from about 1.5% to 3.5%, depending on card type, processor, and pricing model. Premium cards and online sales tend to cost more.
Does this include the flat per-transaction fee?
No. Many processors add a flat fee — often around $0.30 — on top of the percentage. Add that separately, especially on low-value sales.
Can merchants pass the fee on to customers?
In many places, yes — as a surcharge or a separate fee — though card-network rules and local law set limits. Check before adding a surcharge.
Why do processing fees vary so much?
Card type, transaction channel, average ticket size, and risk all affect the rate. Premium rewards cards and card-not-present sales typically cost more to process.

Methodology & Review
Processing fee is the sale amount multiplied by the percentage fee. The model uses a single ad valorem rate; many processors also charge a flat per-transaction fee on top.
