A percentage calculator handles the three everyday percentage questions in one place: what is X percent of a value, what percent one number is of another, and the percentage change between two numbers. Pick the question from the dropdown and fill in the two boxes — the tool applies the matching formula automatically.

The maths behind each is simple. "X% of Y" multiplies Y by X and divides by 100, so 15% of 200 is 200 × 15 ÷ 100 = 30. "X is what % of Y" divides X by Y and multiplies by 100, so 30 out of 200 is 15%. "% change from X to Y" takes the difference over the original, so 200 rising to 260 is (260 − 200) ÷ 200 × 100 = 30%.

Use it for discounts and tips, tax, test scores, tip splitting, commission, growth rates and any of the countless moments daily life throws a percentage at you. Because it accepts decimals and negative numbers, it also works for shrinkage, losses and before-and-after comparisons.

Multiply the number by the percent and divide by 100. For example 15% of 200 is 200 × 15 ÷ 100 = 30.

Divide the percentage by 100, or move the decimal point two places to the left. 15% becomes 0.15 and 7.5% becomes 0.075. To go the other way, multiply the decimal by 100.

Divide the part by the whole and multiply by 100. If 30 of 200 questions are correct, that is 30 ÷ 200 × 100 = 15%. Choose the "X is what % of Y?" mode to do this directly.

It means the value fell. If the new value is smaller than the original, the change formula returns a negative percent — for instance 260 down to 200 is about −23%.
