Let’s dive in.
What Is a Percentage?
A percentage is a number or ratio expressed as a fraction of 100. The symbol “%” denotes percentage. For example, 25% means 25 out of 100.
In mathematical terms:
Percentage (%) = (Part / Whole) × 100
So, if you scored 45 out of 50 on a test, your percentage score is:
(45 ÷ 50) × 100 = 90%
Why Use a Percentage Calculator?
While the math behind percentage is simple, real-world problems can get tricky. Here are a few cases where a calculator is helpful:
- Finding how much 20% off a ₹1,200 product is
- Determining how much GST was added to your bill
- Figuring out what percent your savings grew this year
- Calculating your progress on a project
- Checking nutritional data or fitness performance changes
Instead of crunching numbers manually (or Googling formulas), our tool handles it in seconds.
Types of Percentage Calculations
Here are the 3 most common scenarios where a Percentage Calculator is needed:
1. What is X% of Y?
Example: What is 20% of ₹500?
Formula:
(X ÷ 100) × Y
= (20 ÷ 100) × 500 = ₹100
2. X is what percent of Y?
Example: 60 is what percent of 300?
Formula:
(X ÷ Y) × 100
= (60 ÷ 300) × 100 = 20%
3. What is the percentage increase or decrease?
Example: A product price changed from ₹800 to ₹1,000. What’s the increase?
Formula:
[(New – Old) ÷ Old] × 100
= (200 ÷ 800) × 100 = 25% increase
