Methodology reviewed 2026-07-27. See our review process.

Formula and method

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

  • Future value: presentValue*Math.pow(1+rate/100, years)

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 Present value = 5000, Annual rate = 7 %, Years = 10, this calculator returns Future value = 9835.76.
