How Does a Percentage Calculator Work?
A percentage represents a portion of 100. The basic formula is:
Percentage = (Part ÷ Total) × 100
For example, if you scored 45 out of 60 on a test:
(45 ÷ 60) × 100 = 75%
Your score is therefore 75%.
Common Percentage Calculations
A Free Percentage Calculator can solve several types of problems:
1. Find a Percentage of a Number
To find 20% of 250:
250 × 20 ÷ 100 = 50
So, 20% of 250 = 50.
2. Find What Percentage One Number Is of Another
If you have 30 out of 120:
(30 ÷ 120) × 100 = 25%
So, 30 is 25% of 120.
3. Calculate Percentage Increase
If a price increases from $100 to $125:
[(125 − 100) ÷ 100] × 100 = 25%
The price increased by 25%.
4. Calculate Percentage Decrease
If a price falls from $200 to $150:
[(200 − 150) ÷ 200] × 100 = 25%
The price decreased by 25%.
