WooCommerce Payment Fee & Profit Calculator

Know what an order actually earns after payment fees

A WooCommerce order can look profitable until the payment processor takes its percentage and fixed transaction charge. This calculator models the processor fee, estimated payout, product cost, other order costs, profit and profit margin in one place.

What the calculator includes

• Order amount before processor deductions.
• Percentage plus fixed payment-processing fee.
• Cost of goods for the order.
• Optional shipping, packaging, marketplace or other costs you absorb.
• Estimated payout after the payment fee.
• Estimated order profit and margin.
• A target-profit calculation showing the customer charge required to preserve a chosen profit after percentage and fixed processing fees.

All calculations run locally in your browser. No order, product or financial data is sent to WPToolix.

Why percentage + fixed fees need separate inputs

Many payment processors use a variable percentage plus a fixed amount. The fixed component matters more on low-value orders, so applying only the headline percentage can understate the effective payment cost.

Profit is not the same as payout

The processor payout is what remains after the modeled transaction fee. Profit goes further by subtracting cost of goods and any additional costs you enter. WooCommerce documentation treats cost of goods as the direct cost associated with products sold and uses it to support profit-margin reporting.

How to use it

1. Enter the amount charged to the customer.
2. Enter the percentage and fixed fee from your processor or gateway contract.
3. Add the order cost of goods.
4. Add shipping, packaging or other costs you want included in this decision model.
5. Review payment fee, payout, profit, margin and effective fee rate.
6. Optionally enter a target profit to calculate the customer charge required to preserve that amount after processing fees.

Important limitations

This is a planning calculator, not accounting software and not a quote from a payment processor. It does not automatically model taxes, refunds, disputes, subscriptions, currency conversion, international-card surcharges, tiered pricing, minimum fees, tax treatment of surcharges or country-specific rules. Enter the rates that actually apply to your merchant account and verify the final settlement report.

Should you pass payment fees to customers?

Do not assume that a calculated surcharge is automatically legal or permitted by your card network, processor, gateway contract or local tax rules. WooCommerce extensions can support payment-method fees, but whether you should charge one is a separate compliance and customer-experience decision.

Frequently asked questions

How is the processing fee calculated?

The basic model is order amount × percentage fee + fixed fee. The calculator then subtracts that result from the order amount to estimate payout.

How is profit margin calculated?

Estimated profit is order amount minus payment fee, cost of goods and the additional costs you enter. Margin is that estimated profit divided by the order amount.

Why can a 2.9% gateway cost more than 2.9% of a small order?

Because a fixed transaction charge increases the effective percentage on smaller orders. The tool displays an effective fee rate so this is easier to see.

Does this calculate WooCommerce taxes?

No. Tax treatment varies by store configuration and jurisdiction. Use the amount and costs appropriate for the decision you are modeling, then verify against WooCommerce and your accounting records.
