Percentages are everywhere — from exam scores to discounts, finance, and even your daily tech tasks.
Yet many beginners find them confusing.
In this simple guide, I’ll break percentages down clearly, with examples you can use instantly.
What Is a Percentage?
A percentage is a number out of 100.
50% = 50 out of 100
10% = 10 out of 100
75% = 75 out of 100
Think of percentages as “parts of a whole.” It’s that simple.
Why Percentages Matter in Daily Life
You see percentages in:
Shopping: “40% off sale”
Banking: interest rates
Health: body fat percentage
Exams: “You scored 86%”
Business: profit margin
Once you understand the basics, percentages are extremely practical.
The Basic Percentage Formula
Here’s the simplest formula:
Percentage (%) = (Part / Whole) × 100
Example:
You scored 45 marks out of 50:
Percentage = (45 / 50) × 100 = 90%
