## Article

You priced the print at £32 because “that covers the blank and a bit of profit.” Then Stripe takes a cut, Etsy takes a cut, and a 10% off code you ran last weekend silently stacked. The payout is not £32. It never was.

A platform fee calculator shows net before you advertise a sale you cannot afford.

## The simple fee model

Fee = (Sale amount × percentage) + fixed feeNet = Sale − Fee

That is how most processors describe card-present or online rates in the small print. Marketplaces add listing or transaction percentages on top. Presets in tools are approximate — platforms change schedules. Use custom rates when you have the current contract in front of you.

Open [BryteTools Platform Fee Calculator](https://brytetools.com/tools/platform-fee-calculator). Pick Stripe, PayPal, Etsy, eBay, or Custom. Enter the sale amount. You get fee and net payout. Nothing is stored. No account.

Then run the leftover through [Profit Margin Calculator](https://brytetools.com/tools/profit-margin-calculator) against true COGS. If net after fees is £18 and the product costs £16 to make and ship, you are not running a shop — you are funding the platforms.

## Worked example

Sale £40. Processor 1.5% + £0.20 (illustrative). Fee = £0.60 + £0.20 = £0.80. Net = £39.20. Add a 6.5% marketplace cut on the same sale and the stack gets ugly fast. Always model combined fees, not the one logo on the checkout button.

StackWhat to model

Shopify + StripeShopify plan is fixed; Stripe is per-charge. Do not double-count VAT handling.

EtsyTransaction + payment processing + offsite ads if you use them

eBayFinal value fees vary by category — custom rate is safer than a guess

PayPal checkoutDomestic vs international rates differ

## Pricing moves that protect net

- Raise list price so advertised discounts still clear contribution after fees.

- Drop low-AOV SKUs where the fixed fee eats the sale.

- Offer pickup or simpler shipping if packing cost plus fees leave pennies.

- Re-check break-even with [Break-even Calculator](https://brytetools.com/tools/break-even-calculator) using net price, not list.

## Mistakes

- Using last year’s rate card. Presets drift. Custom exists for a reason.

- Forgetting refunds. Some fees are not fully returned.

- Comparing list prices across marketplaces without netting fees and ads.

- Ignoring FX. Cross-border payouts are another haircut.

## FAQ

Are preset fees exact?No. They are approximate. Platforms change rates — use Custom for your schedule.

How are fees calculated?Fee = (Sale × %) + fixed fee. Net = Sale − Fee.

Can I add my own platform?Yes. Select Custom and enter percentage and fixed fee.

Does this include VAT?Enter the amount you are charged on. For UK VAT on the customer price, use [VAT Calculator](https://brytetools.com/tools/vat-calculator) separately so you do not mix tax with processor math.

Is my sales data stored?No. Calculations run in your browser.
