How MemberMath calculates fees: method & assumptions

Assumptions

• Every member pays the full monthly price once per month by a US domestic credit card.
• No sales tax/VAT, refunds, chargebacks, payout fees, currency conversion or add-ons.
• Net revenue = gross - platform plan fee - platform transaction fee - payment processing fees.

Data confidence

• ✓ verified: Read directly from the vendor's own public page/docs.
• ◐ secondary source: Only found via third-party sources or derived; vendor page not readable/confirmed.
• ? assumed: Our modeling assumption; vendor page does not state it.
• ? uncertain: Unclear or ambiguous on the source page.

All figures come from one maintained data set. Every number has a source link and a last-verified date, and an automated check watches vendor pricing pages for changes.
