Net
What you want left after the processor takes its cut.
Tool 04
Fee Reverse Calculator — Net → Gross Invoice Amount
You want to clear a exact net amount. This tells you how much to invoice so Stripe, PayPal, Square, or Paddle fees don’t cut into it.
Gross
What you charge the customer on the invoice or checkout.
Fees
Usually a percentage plus a fixed amount — plus optional cross-border and FX add-ons.
Formula
gross = (net + fixed) ÷ (1 − effective fee%). Confirm rates with your gateway.
Example
Want $1,000 net on Stripe-like fees (2.9% + $0.30): gross ≈ $1,030.18. Turn on cross-border (+1%) and it rises to about $1,040.89 — FX can push it further.
How do I reverse calculate Stripe fees?
Gross = (desired net + fixed fee) ÷ (1 − percent fee). Example: want $1,000 net at 2.9% + $0.30 → invoice about $1,030.18. Cross-border or FX add-ons raise the gross further.
How is a fee reverse calculator different from a price calculator?
A price calculator builds subscription tiers from cost and margin. A fee reverse calculator answers one invoice question: what gross amount covers the net you want after processor fees.
When should I add cross-border or FX fees?
Cross-border: the card country differs from your processor account country. FX: you settle in a different currency than the charge. Both are planning estimates — confirm the real schedule in your dashboard.
Does a fee reverse calculator include tax or VAT?
No. It only reverses processor fees. Add tax on top if your invoices require it.
