Rise and Run Calculator

This free rise and run calculator gives you an answer in a couple of seconds, and shows the full working underneath so you can check it rather than take it on trust. Change any value and the result updates immediately. Nothing is stored, nothing is sent anywhere, and there is no sign-up.

A dedicated engine for this calculation is still being built. In the meantime, here is a general-purpose calculator.

How to use this rise and run calculator

  1. Fill in your values. Every field starts with a sensible default, so you can change one number at a time and watch what it does to the result.
  2. Read the result. The headline figure sits in the pink box, with supporting numbers listed below it.
  3. Check the working. The breakdown shows each formula and the same formula with your numbers substituted in, so you can follow the method or reproduce it by hand.
