Basic Formula for Calculating Percentage
The core formula for calculating what percentage one number is of another is quite simple:
Percentage = (Value / Total Value) * 100
Where:
- Value is the number you want to express as a percentage.
- Total Value is the whole or the reference number.
Step-by-Step Guide with Examples

-
Divide the Value by the Total Value: Perform the division to get a decimal.
-
Multiply by 100: Multiply the decimal by 100 to convert it into a percentage.

A shirt that originally costs $50 is on sale for $40. To find the discount percentage:
- Calculate the discount amount: $50 - $40 = $10
- Use the original price as the Total Value: Percentage = (10 / 50) * 100 = 20%
