Marketplace fees are death by a thousand cuts: a transaction percentage here, a payment processing fee there, a listing fee you forgot about. Price too low and you work for free; price too high and you don't sell.
These calculators work out what you actually keep — Shopify and Etsy fees, Stripe processing, eBay final value fees, TikTok Shop commissions — after every cut is taken. Punch in your numbers, see the real margin, then set a price you can live with.

Questions
Why is my real profit lower than I expected after fees?
Usually because a few small charges stack up. Etsy takes a 6.5% transaction fee on top of the $0.20 listing fee and payment processing, and shipping you charge counts toward the fee base. Run an order through the fee calculator and every line shows up separately.
Do the fee rates here stay current?
Platforms change them more often than you'd think, so each preset carries a source and a review date. If a rate is past its review date, we turn the preset off rather than show you something stale. You can always type in the rate from your own seller dashboard.
What's the Stripe fee on a $100 sale?
With the standard US card rate of 2.9% + $0.30, you'd pay $3.20 and keep $96.80. The Stripe calculator also runs backwards, so you can enter the amount you want to receive and see what to charge.
