Turns the fee soup — interchange, assessments, processor markup, per-transaction fees — into one honest number: your effective rate.
- Enter monthly card sales volume and transaction count (or average ticket).
- Enter your quoted rates: percentage plus per-transaction fee, plus any monthly/statement fees.
- Read your effective rate and see exactly where each dollar of fees goes.
Interchange, and the Only Number That Matters
Effective rate = Total fees ÷ Total sales. Worked example: $10,000/month across 200 transactions at 2.9% + $0.30: percentage fees $290 + transaction fees $60 = $350, an effective rate of 3.5%. Interchange-plus pricing makes the anatomy visible: interchange (set by Visa/MC, ~1.4–2.5% depending on card type) + assessments (~0.13%) + your processor's markup — and the markup is the only negotiable slice. Flat-rate pricing (Stripe/Square-class 2.9%+30¢) is simple and right for under ~$15k/month; above ~$30–50k/month, interchange-plus typically saves 0.3–0.8 points, which is $360–$960/month on $45k. Also weight card mix: premium/rewards cards cost 0.3–1.0 points more than debit.
