About SaaS Fee Calculator
SaaS Fee Calculator is a free planning tool for founders comparing Stripe, Paddle, Lemon Squeezy, Polar, and merchant-of-record payment setups.
Why this exists
Payment provider comparisons often stop at headline fees. That can be misleading for SaaS products because order size, international card share, refunds, chargebacks, and tax operations can change the real result.
What the calculator does
The calculator estimates take-home revenue from one set of assumptions and shows how provider fee models differ. It is designed for early SaaS planning, pricing experiments, checkout migration decisions, and merchant-of-record comparisons.
What it does not do
The tool is not tax, legal, accounting, or financial advice. Provider pricing can change, and custom pricing may differ. Always confirm final numbers with official provider pricing pages and qualified professionals where needed.
