Percentage Fee Calculator

For a regular fee calculation, treat the amount as the payment before fees. The calculator multiplies that amount by the fee rate, rounds the fee to the nearest cent, and subtracts it to show your net amount.

The basic formula is fee = amount × (fee rate ÷ 100). For example, a 3% fee on $100 is $100 × 0.03 = $3.00, so the amount after the fee is $97.00.

A 3% fee on a $100 payment is $3.00, leaving $97.00. That is different from asking how much to charge so that $100 remains after a 3% fee; for that, the required charge is $103.09.

The table compares both questions across several fee rates. It is a simple rate comparison, not a list of current fees from any payment provider or marketplace.

A basic percentage calculator usually returns only the percentage value. This tool also subtracts the rounded deduction to show the take-home amount and works backward to find the smallest cent-level charge for a target payout. If a transaction includes fixed or per-item costs as well, use the reverse fee calculator to model the complete pricing rule.

Suppose a freelancer sends a $750 invoice and the payment rate is 2.9%. The deduction is $21.75, so the proceeds are $728.25. If the freelancer instead needs to take home exactly $750, the minimum gross charge is $772.40: 2.9% of that amount rounds to $22.40, leaving $750.00.

For a sales commission example, 7.5% of a $480 sale is $36.00, leaving $444.00 before taxes, refunds, shipping, or other costs. A $1,250 creator payout with a 4% platform deduction has a $50.00 fee and leaves $1,200.00.

These examples isolate one percentage so you can compare the result with separate lines on an invoice or payout statement. Our payment processing fee guide explains how fixed charges, refunds, and effective rates can change the overall cost.

Use the reverse result when the amount you enter is what you need to keep. This gross-up fee calculator starts with target net amount ÷ (1 − fee rate). It then checks the rounded forward fee to find the smallest cent-level charge that reaches the target.

Do not simply add the percentage to your target. If you add 3% to $100 and charge $103, the 3% fee is calculated on $103. The $3.09 fee leaves only $99.91. Grossing up the amount gives a charge of $103.09, whose $3.09 fee leaves exactly $100.00.

This tool models one USD amount and one percentage deduction. It works well for a simple transaction fee, commission, service fee, referral fee, management fee, or revenue share when no other charge applies.

It does not include fixed or per-item charges. It also excludes tax, currency conversion, tiered pricing, fee limits, refund rules, and provider-specific exceptions.

If your fee has percentage and fixed components, use the general fee calculator. Always check the provider's current terms before using an estimate for pricing or invoicing.

The calculator works in integer cents and rounds the fee half up to the nearest cent before subtracting it. For example, 1% of $0.50 is half a cent ($0.005), which rounds to a $0.01 fee.

Small payments show why the boundary matters. At 1.5%, a $0.30 payment produces $0.0045, which rounds to a $0.00 deduction. A $0.34 payment produces $0.0051, which rounds to $0.01 and leaves $0.33. The same one-cent step can change the minimum gross amount found in reverse mode.

The reverse result uses the same rounded forward calculation instead of an unrounded formula result. This keeps the displayed charge, deduction, and payout consistent at the cent level.

A pricing rule that also adds $0.30 is different. A 3% plus $0.30 fee on $100 totals $3.30 and leaves $96.70. This percentage-only result is $3.00 and $97.00.

We check forward examples, reverse results, and values on both sides of cent-rounding boundaries with automated tests. Read our calculation methodology or report a calculation difference.
