The Percentage of a number formula
Result = (Percentage ÷ 100) × Number
Convert the percentage to a fraction by dividing by 100, then multiply by the number. It finds a part of a whole; it does not calculate percentage change between two values.
Example
A 15% discount on a 240 product.
(15 ÷ 100) × 240 = 36 off
Worked example: 15% of 240
You want to know what 15% of 240 is.
- Result = (15 ÷ 100) × 240 = 36.
- Ten percent of 240 is 24, and half of that is 12.
- 24 + 12 = 36 confirms the answer.
What to do next: Enter the percentage as a plain number, for example 15 for 15%, to avoid mistakes.
