How to use it

  1. Annual Salary — one of the values the calculation builds from; the result reflects exactly what you type here.

  4. The output panel in retirement contribution impact leads with the headline result and follows with the steps behind it, so the value can be checked rather than assumed.
  5. Iterate. Vary the inputs one at a time; the movement in the output shows which lever matters most for your retirement contribution impact question.
