Tips for an accurate result

  • Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
  • Round only at the very end. Rounding inputs early can shift the final answer noticeably.
  • Re-run the numbers whenever an input changes, rather than estimating from an old result.
  • Annual rates must be converted to the period you are calculating for (for example, divide an annual rate by 12 for a monthly figure).
