Use this calculator to estimate the net amount left after percentage-based and fixed payment processor fees are deducted.
It is useful for SaaS, digital products, one-off invoices, online stores, and any business where payment processing has a noticeable impact on margin.
Processor fees matter most on lower-priced transactions and discount-heavy offers.
Why do fixed fees matter so much?
Because they hit every transaction equally, so they take a larger percentage out of smaller payments.
Can I use this for processors other than Stripe?
Yes. The math works for any processor with a percentage fee plus fixed fee model.
Should I pass fees on to customers?
That depends on market expectations and local rules. At minimum, you should understand the impact before finalizing pricing.
