How the Percentage of a Number Calculator Works
To find a percentage of a number, turn the percentage into a decimal (divide by 100) and multiply. 15% of 200 is 0.15 × 200 = 30. This calculator does it instantly for any values — tips, taxes, discounts, grades and more.
Percentages are just fractions out of 100, so “15%” means 15 per hundred, and taking 15% of something scales it to that share.
result = (percent ÷ 100) × number
