A percentage is a way of expressing a number as a fraction of 100. It allows you to compare values, measure changes, and understand proportions easily.

📊 How to Calculate Percentages

There are three common types of percentage calculations that this percentage calculator can handle:

1. Find a Percentage of a Number

To calculate a percentage of a number, multiply the percentage by the number and divide by 100.

Formula:

Percentage × Number ÷ 100

Example:

20% of 150 = (20 × 150) ÷ 100 = 30

This is commonly used when calculating discounts, taxes, or portions of a value.

2. Find What Percentage One Number Is of Another

To calculate what percentage one number is of another:

Formula:

(Part ÷ Whole) × 100

Example:

30 is what percentage of 150?
(30 ÷ 150) × 100 = 20%

This method is useful for comparing values and understanding proportions.

3. Calculate Percentage Increase or Decrease

To calculate percentage change:

Formula:

((New Value − Original Value) ÷ Original Value) × 100

Example:

From 100 to 150 = 50% increase

This is commonly used in finance, pricing, and performance tracking.
