Mathematical Audit

Buy Me a Coffee Net Earnings Formula

Buy Me a Coffee charges a 5% platform fee plus Stripe's payment processing fee on every transaction.

Platform Fee = Transaction Amount × 5%
Stripe Processing Fee = Transaction Amount × 2.9% + $0.30
International Surcharge = Transaction Amount × 1% (for non-US transactions)
Total Fees = Platform Fee + Stripe Fee + International Surcharge (if applicable)
Net Earnings = Transaction Amount − Total Fees
Monthly Net = Net Earnings × Transactions per Month

Buy Me a Coffee does not charge a monthly subscription fee — they earn revenue through the 5% platform fee. Supporters can optionally cover processing fees, which would pass the full amount to you. Membership tiers may incur additional 0.5% subscription processing fees.
