- X is what percent of Y? (e.g., 30 is what percent of 150?)
- Percentage Increase/Decrease: What's the percentage change from X to Y? (e.g., What is the percentage increase from 80 to 100?)
No need to remember complicated formulas or do long calculations by hand. Just enter your numbers, and let our calculator do the work!
Understanding Percentages: A Quick Refresher
A percentage is simply a way of expressing a number as a fraction of 100. The term "percent" literally means "per hundred." So, when you see 20%, it means 20 out of every 100, or 20/100.
How to Calculate Percentages Manually (If You Want To!)
While our calculator is super convenient, understanding the underlying math is always a good idea. Here's a breakdown of how to calculate percentages manually:
1. Finding X% of Y
To find what a certain percent of a number is, convert the percentage to a decimal (divide by 100) and then multiply it by the number. For example:
What is 25% of 80?
- Convert 25% to a decimal: 25 / 100 = 0.25
- Multiply the decimal by 80: 0.25 * 80 = 20
- Therefore, 25% of 80 is 20.

2. Determining X as a Percentage of Y
To find out what percentage one number represents of another, divide the first number by the second and then multiply by 100. For example:
12 is what percent of 48?
- Divide 12 by 48: 12 / 48 = 0.25
- Multiply the result by 100: 0.25 * 100 = 25
- Therefore, 12 is 25% of 48.

3. Calculating Percentage Change
Percentage change shows the extent to which something gains or loses value. Use the formula to calculate Percentage difference: |V1 - V2| / [(V1 + V2) /2] × 100
