Why use this payment processing fees calculator?
Estimate a planning budget for payment processing using editable assumptions instead of relying on a headline vendor or contractor price. The model combines percentage-based fees, per-item fees and fixed monthly fees to estimate total cost and the effective rate on processed volume.
Inputs used in this model
- Monthly payment volume: default example 250,000
- Variable processing fee rate: default example 2.5
- Monthly transactions: default example 2,500
- Per-transaction fee: default example 0.3
- Monthly gateway, account or platform fees: default example 100
How to interpret the result
The effective rate is useful for comparing fee structures only when transaction count, volume and fixed-charge assumptions are normalized. Change the most uncertain inputs and compare multiple scenarios rather than relying on a single default case.
How to use it
Start with the inputs shown above, review the assumptions or options, then generate the result. Where the tool creates a file, keep the original until you have opened and checked the downloaded output.
