How to use a calculator responsibly

  1. Open the relevant tool and read the input labels before entering values.
  2. Use the same units and time period requested by the calculator.
  3. Review the formula, worked example and assumptions on the tool page.
  4. Compare important tax, finance or utility results with the relevant official source or provider.

Each tool page links back to the calculator directory and the methodology page, so visitors can move between tools and understand the assumptions behind an estimate.
