Assumptions and limits

  • The result is derived only from the single input listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 6 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How do I convert 37.5% to a fraction?

37.5/100 = 375/1000 (multiply by 10 to clear the decimal). GCD(375,1000)=125, so 375÷125 / 1000÷125 = 3/8.

What about percentages greater than 100%?

They become improper fractions. For example, 150% = 150/100 = 3/2.
