About the Percentage Calculator
The percentage calculator answers the most common percentage question: "What is X% of Y?" To find a percentage of a number, convert the percentage to a decimal by dividing by 100, then multiply by the number.
Formula: Result = (Percent ÷ 100) × Value
For example, 20% of 150 is (20 ÷ 100) × 150 = 30. This calculation is used everywhere from calculating discounts and tips to figuring out test scores and statistics.
