Free Payments Calculators
Practical calculators for the numbers that run a payments business — processing fees, your blended effective rate, the true cost of chargebacks, currency-conversion markups, subscription MRR and ARR, and a side-by-side processor comparison.
Payment Fee Calculator 💳
Work out the processing fee on a transaction from a percentage rate plus a fixed fee — see the total fee, the net you receive, the effective rate, and totals across a batch of sales
Effective Rate Calculator 📉
Divide your total monthly fees by the volume you processed to reveal the one blended effective rate behind the pricing — plus your true cost per transaction
Chargeback Cost Calculator ⚠️
Add the dispute fee, lost goods, and non-refunded processing fee for the true cost of a chargeback, then project the annual hit from your chargeback rate and volume
Currency Conversion Calculator 🌍
Convert at the mid-market rate, then apply an FX markup to see what you actually receive, exactly what the markup costs you, and your real effective rate
Subscription Revenue Calculator 📈
Turn subscribers and price into MRR and ARR, then project 12 months of recurring revenue adjusted for monthly churn and optional growth
Processor Comparison Calculator ⚖️
Compare two processors — rate, fixed fee, and monthly fee — at your volume and average ticket to see each one's cost, the cheaper choice, and annual savings
