Percentage Difference Calculator

Are you looking to quickly and accurately determine the percentage difference between two values? The Percentage Difference Calculator is a simple yet…

Inputs

The percentage change should be used when you want to find increase/decrease from the old to the new value. Percentage difference does not differentiate which value is newer.

Results

Enter your values above. The results appear here as soon as there is enough information to calculate them.

How to use the Percentage Difference Calculator

  1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
  2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
  3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
  4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

percentage_difference = sqrt(pow(a-b, 2))/((a+b)/2)

difference = sqrt(pow(a-b, 2))

change = (final - initial)/abs(initial)

difference_change = final - initial

initial = final/(change + 1)
