Percentage Calculator: % of, % Change, What %
Find X% of a number, what percent one number is of another, and the percentage change between two numbers.
Year-by-year table
Three answers at once
- A% of B = A × B ÷ 100. Example: 25% of 200 = 50.
- A is what % of B = A ÷ B × 100. Example: 25 is 12.5% of 200.
- % change from A to B = (B − A) ÷ A × 100. Example: from 25 to 200 is a 700% rise.
Percentage points are different from percent: a rate rising from 6% to 6.5% is a 0.5 percentage-point rise but an 8.3% increase.
