Calculate what X% of Y equals, and see the value after adding or removing that percentage.
Enter values above and click Calculate — results will appear here with the formula explained.
A percentage is a fraction of 100. To find X% of a number, convert the percentage to a decimal by dividing by 100, then multiply by the number. 15% becomes 0.15, so 15% of 200 is 0.15 × 200 = 30.
The same percentage can be applied in the other direction: increasing a value by X% means multiplying by (1 + X/100), and decreasing means multiplying by (1 − X/100). Both results are shown above so you can check discounts, markups and taxes at a glance.
