What this card fee estimate includes
The calculator does not guess a universal card rate. It turns disclosed terms into a transparent per-sale estimate.
- The percentage applies to the transaction amount, then the fixed per-transaction charge is added.
- Monthly and other costs are optional allocations, not inferred charges.
- The effective rate divides every modeled fee by the transaction amount, so fixed fees weigh more heavily on smaller sales.
- The 2.9% plus $0.30 example matches Stripe's public U.S. domestic online-card pricing reviewed August 22, 2026. Edit it for your actual terms.
