About Percentage calculator
Work with percentages in four distinct ways: a percentage of a value, one value as a percentage of another, change from an original value, or symmetric percentage difference.
Steps, and limitations
How to use it

- Enter the two values and inspect the labeled formula.
- Copy the result, checking which value is used as the denominator.
Things to know
- Percentage change uses the absolute original value as the base. Zero denominators are rejected.
- Percentage difference uses the mean of absolute values. This is not the same as directional percentage change.
