PlatformMath is a free calculator comparing creator platform fees across Skool, Kajabi, Whop, Stan Store and Teachable, so creators can see their estimated take-home after fees. Fee figures link to each platform's official pages with a check date, and some are labeled as estimates. The site earns affiliate commissions and runs paid sponsor slots, which it labels separately from its rankings, and it is not affiliated with any platform.
Platform fee pages are confusing and hide transaction and payout costs. I wanted creators to compare real take-home earnings side by side before picking a platform.
