📐 Mathematical Formula & Derivation
F_{Stripe} = N_{tx} \times (A \times r_{eff} + 0.30), \quad F_{MoR} = N_{tx} \times (A \times 0.05 + 0.50) 🔬 Engineering Methodology & Benchmark Analysis
Founders often compare Stripe’s headline 2.9% + $0.30 rate directly against Paddle or LemonSqueezy’s 5.0% + $0.50 rate. However, once you enable Stripe Billing (0.5%–0.7%), Stripe Tax (0.5%), Stripe Invoicing (0.4%), and accept international cards (+1.5% cross-border + 1% currency conversion), your true effective Stripe rate frequently reaches 4.6% to 5.4%.
Furthermore, a Merchant of Record (MoR) acts as the legal reseller—handling EU VAT, UK VAT, and US state sales tax filings on their own tax ID.
