About this tool
The calculator covers the three things people usually mean by a percentage question. X% of Y gives a share of a number, for example a 15% tip or 18% tax. X is what % of Y turns two numbers into a percentage, such as marks out of a total. % change compares an old and a new value, so you can see a price rise or a fall in sales.
It's meant for students, shopkeepers and anyone checking a bill or a score. Results show up to six decimals with noise removed, and the formula is printed under every answer so you can check it by hand.

Questions
How do I find X% of a number?
Multiply the number by X and divide by 100. So 15% of 2,000 is 2,000 × 15 ÷ 100 = 300.
How is percentage change calculated?
Subtract the old value from the new one, divide by the old value and multiply by 100. Going from 80 to 100 is (100 − 80) ÷ 80 × 100 = 25% up; going from 100 to 80 is 20% down.
Why is a 20% rise followed by a 20% fall not back to the start?
The fall is taken from a bigger number. 100 up 20% is 120, and 20% of 120 is 24, which leaves 96.
What is the difference between percent and percentage points?
A rate moving from 5% to 7% is 2 percentage points higher, but a 40% relative increase. This calculator's % change gives the relative figure.
