About

Fee math, without the spin.

PlatformMath is an independent calculator for creators choosing between Skool, Kajabi, Whop, Stan Store and Teachable.

How the data works

Every number is read from the platform's official pricing or help page, with the source and date shown.
Anything we couldn't confirm on an official page is marked unverified.
Fees modeled for US domestic card sales. Taxes, currency conversion and add-ons are excluded.
Raw data is public: data/pricing.json.

How we make money

Some platform links are affiliate links, and we sell clearly-labeled sponsor slots. Neither changes calculator results or comparisons.
