Exchange Rate Calculator - Free Online Tool

Formula and method

This calculator uses the values you enter and applies the calculation immediately in your browser. The main output formulas are:

Converted amount: amount*rate*(1-fee/100)

Some formulas are undefined for certain input combinations, such as division by zero, equal x-values in a slope calculation, or logarithms of non-positive numbers. In those cases the live tool reports that the result is undefined instead of displaying Infinity or NaN.

Examples

Example: with Amount = 100, Exchange rate = 0.92 target/source, Fee = 0 %, this calculator returns Converted amount = 92.
