Free tool

What Stripe actually keeps from every transaction.

Pick your country, plug in a price, see the breakdown. Or work backwards — enter what you want to net, and we'll tell you what to charge.

When you charge $100 with Stripe in the US, Stripe takes roughly $3.20. Charge in Europe, that can be closer to €1.65. International cards, premium cards, Stripe Tax, payment options, and application fees can all change the number.

Use the calculator to sanity-check the fee before you publish the Offer, then use Plandalf prices, invoices, and hosted checkout to keep that pricing decision connected to the actual sale.

What this tool does

  • Forward mode — plug in a price, see what Stripe keeps and what you net.
  • Reverse mode — plug in what you want to net, see what to charge the customer.
  • Country-aware — Stripe fees vary by processing country, currency, and card type.
  • Offer-aware — use the result when setting prices, coupons, payment options, and invoices in Plandalf.

Why we built it

Most “Stripe fee calculators” out there are based on the US 2.9% + 30¢ — and stop there. That’s wrong for almost everyone outside the US, wrong for international cards anywhere, wrong for Stripe’s Premium card surcharges, and wrong if you’re using Stripe Tax or Stripe Connect with application fees.

The point is not just fee trivia. If the margin is wrong, the checkout, coupon, invoice, and post-purchase automation all inherit the wrong commercial assumption.

How to use the result in Plandalf

  1. Pick the country, currency, card type, and sale amount in the calculator.
  2. Decide whether the buyer should pay the listed price or whether you need to gross up to a target net amount.
  3. Create or update the price attached to the product.
  4. Confirm the right payment options are enabled on the Stripe integration.
  5. Test the hosted checkout before publishing the Offer.

If you are choosing between a plain processor checkout and an offer layer, read Plandalf vs Stripe Checkout. Stripe should still handle the charge; Plandalf keeps the offer, pricing, invoice, and follow-up context connected.
