Percentages are used every day when calculating discounts, taxes, commissions, exam scores, savings, business performance and many other figures. Fortunately, calculating a percentage of a number is simple once you understand the basic formula.
What Is a Percentage?
A percentage represents a value as a portion of 100. For example, 25% means 25 out of every 100, while 50% represents half of a total.
Understanding this concept makes percentage calculations much easier.
How to Calculate a Percentage of a Number
To find a percentage of any number, use:
Percentage value = (Percentage ÷ 100) × Number
For example, suppose you want to calculate 20% of 500.
20 ÷ 100 = 0.20
0.20 × 500 = 100
Therefore:
20% of 500 = 100
Another Example
What is 15% of 800?
15 ÷ 100 = 0.15
0.15 × 800 = 120
So:
15% of 800 = 120
