Planning math for a Shopify merchant who absorbs card fees. Official first paint is Basic Shopify Payments domestic 2.9% + $0.30 on $100 → KEEP $96.80. Formula: KEEP = G − (0.029G + 0.30). Grow 2.7 / Advanced 2.5, premium cards 3.5%+$0.30, intl +1%, in-person Basic 2.6%+$0.10, PayPal Wallet starting 3.49%+49¢, and Plus from 2.25%+$0.30 are presets / extras, not first paint. Third-party extra 2%/1%/0.6%/0.2% plus a gateway fee you type — this page does not invent Stripe as that gateway. Monthly software is a typed line, default $0, not inside KEEP. No official surcharge % is printed. Not affiliated. Planning only.
