How This Calculator Works
Amount → Net mode takes the gross amount you charge a payer and deducts the processor's percentage-based fee plus its fixed per-transaction fee to show what you actually receive.
Target Net → Amount mode solves the same formula in reverse: enter the amount you want to receive after fees, and it tells you what to charge so the fee doesn't cut into your target payout.
