How this calculator works

Calculate monthly fees from transaction amount, fee rate, fixed fees, VAT, and transaction count.

Monthly Fees = ((Amount × Fee Rate) + Fixed Fee) × Transactions × (1 + VAT) + Other Fees.

Example calculation

For 100 transactions of $100 with 2.9% + $0.30, monthly processing fees are about $320 before tax or platform fees.

Tips to improve the result

  • Include fixed fees because they matter on small transactions.
  • Compare effective fee rate, not only advertised fee rate.
  • Annualize fees to understand their long-term drag.
  • Use net amount for revenue planning.

The rating is a practical planning signal, not financial advice. Adjust the assumptions to compare different monthly scenarios.

FAQ

Is this calculator financial advice?

No. It is an educational planning estimate based on your inputs.

How often should I update the numbers?

Update the numbers monthly or whenever income, debt, expenses, or investment assumptions change.

Why does the rating matter?

The rating gives a quick interpretation so the result is easier to act on.

Can I use this for business finances?

You can use it for simple estimates, but business accounting may require more detailed tools.

Are taxes included?

Only when a tax input is available. Otherwise the calculator uses the values you enter as-is.
