How this tool works

Percentage tools answer three common questions: what is X percent of Y, what percent is X of Y, and what is the percent change from X to Y. These appear in discounts, marks, growth and finance.

Formula

X% of Y = (X/100)×Y. X as percent of Y = (X/Y)×100. Percent change = ((Y−X)/X)×100.

Example

25% of 200 is 50. 50 is 25% of 200. A price rising from 200 to 250 is a 25% increase.

Frequently asked questions

Is percent change the same as percentage points?

No. A rate moving from 10% to 12% is a 2 percentage point rise, but a 20% relative change.

Can the result be over 100%?

Yes. If a value more than doubles, percent change exceeds 100%.
