Percentage Calculator FAQs
How do I calculate a percentage of a number?
Divide the percentage by 100 and multiply it by the base number.
What is the difference between percent and percentage points?
A move from 20% to 25% is 5 percentage points, but it is a 25% increase relative to 20%.
Why should I check the base value?
Using the wrong starting value is one of the most common causes of an incorrect percentage result.
