Flat Rate vs Interchange-Plus Cost Calculator
Compare two pricing scenarios using your own monthly activity, rates, fees, and estimated interchange and card-network costs. UME does not insert an assumed interchange rate.
Add monthly fees

Enter interchange-plus monthly fees of $0 or more.
Flat-rate estimate
- Percentage fee
- Transaction fees

Interchange-plus estimate
- Estimated interchange and network costs
- Processor percentage markup
- Processor transaction markup
- Monthly fees
- Estimated total / month
How this comparison works
Flat-rate pricing combines processing costs into the rate and transaction fees you enter. The interchange-plus estimate uses your interchange and network cost estimate plus the processor markup and other fees you enter.
Important assumptions
- This calculator compares the pricing terms you enter. It does not predict your future interchange cost.
- The interchange-plus result depends heavily on the interchange and network cost you enter. Actual pass-through costs vary with card mix, transaction type, merchant category, acceptance method, and other factors.
- The comparison assumes the same monthly card sales and transaction count under both pricing models.
- Chargebacks, equipment costs, optional services, taxes, and other charges are excluded unless represented in the monthly fees you enter.
