About this calculator
To take a percentage of a value, divide the percentage by 100 and multiply: 20% of 150 is 150 × 0.20 = 30. The word percent literally means "per hundred", so 20% is just the fraction 20/100.
Two quick mental tricks: 10% is the value with the decimal point moved one place left, and any percentage can be built from that — 5% is half of 10%, 20% is double it. And X% of Y always equals Y% of X: 8% of 25 is the same as 25% of 8, which is often easier to see at a glance.
