How It Works: The Core Formulas
The calculator uses three primary formulas based on common percentage questions:
1. What is Y% of X? Result = (Y / 100) * X
2. X is what % of Y? Result = (X / Y) * 100
3. X is Y% of what? Result = X / (Y / 100)
Frequently Asked Questions
How do you calculate a percentage of a number?
To calculate a percentage of a number, you convert the percentage to a decimal and multiply it by the number. For example, to find 20% of 50, you calculate 0.20 × 50 = 10. Our calculator can do this and other common percentage calculations for you.
How do you calculate what percentage one number is of another?
To find what percentage one number (part) is of another (whole), you divide the part by the whole and multiply the result by 100. For example, to find what percentage 10 is of 50, you calculate (10 / 50) × 100 = 20%.
How do you calculate percentage increase or decrease?
To calculate percentage change, subtract the initial value from the final value to find the difference. Then, divide the difference by the initial value and multiply by 100. A positive result is a percentage increase, and a negative result is a percentage decrease.
