Quick guide

How to use this calculator

  1. Enter the amount, quotation direction, timing, and fees from the real scenario you want to evaluate.
  2. Use consistent currencies and periods; provider quotes can differ because they include different spreads, deductions, and settlement conventions.
  3. Read the companion outputs and boundaries before comparing providers, planning a payment, or interpreting a currency result.

Calculation method

Calculation method

Home cost per row = foreign amount × home-per-foreign rate × (1 + row fee rate); budget = converted row costs + contingency on those row costs + fixed fees.

Calculations use exact fixed-decimal arithmetic. No live rate, provider price, country rule, or legal payment obligation is selected automatically.

Worked example

Worked example

A 500 foreign hotel expense at 1.10 with a 2% fee costs 561 home units before any contingency or fixed fees.

Home cost per row = foreign amount × home-per-foreign rate × (1 + row fee rate); budget = converted row costs + contingency on those row costs + fixed fees.

Supported inputs

Precision and limits

Entered quote and fee scope

Every rate and fee is visitor-entered and may have a different timestamp. The result is a planning budget, not a live quote or guarantee that a card, cash desk, or ATM will use the entered rate.

Currency and quotation direction

Labels state the required quotation direction. Reversing a currency pair without taking its reciprocal changes the result; all costs must be expressed in the currency named by their labels.

Provider and market boundary

Results are scenarios, not executable quotes. Actual rates, payment acceptance, transfer speed, intermediary deductions, settlement timing, disputes, and provider eligibility may differ.

Regulatory boundary

The calculator does not determine disclosure compliance, lawful surcharges, refund or chargeback rights, tax, sanctions, money-transmission obligations, or consumer protections in any jurisdiction.

Precision and privacy

Plain decimals accept up to 30 digits and 12 decimal places. Calculations remain in this browser and raw entered values are not submitted to 365CALCS.COM.
