What Is a Percentage?

A percentage is a number expressed as a fraction of 100.

The word "percent" literally means "per hundred."

For example:

• 10% means 10 out of 100

• 25% means 25 out of 100

• 50% means 50 out of 100

• 100% means the whole amount

Percentages make it easier to compare values and understand proportions.

Percentage Formula

The standard percentage formula is:

Percentage = (Part ÷ Whole) × 100

For example:

If a student scores 80 marks out of 100:

Percentage = (80 ÷ 100) × 100

Percentage = 80%

This simple formula is the foundation of most percentage calculations.

Find Percentage of a Number

One of the most common uses of the calculator is finding a percentage of a number.

Example

What is 25% of 400?

Formula:

25 ÷ 100 × 400

Answer:

100

The calculator performs this calculation instantly.

Percentage Increase Calculator

Percentage increase shows how much a value has increased compared to its original value.

Formula

Percentage Increase = ((New Value - Original Value) ÷ Original Value) × 100

Example

Original Price = $100

New Price = $150

Percentage Increase:

((150 - 100) ÷ 100) × 100

= 50%

The value increased by 50%.

Percentage Decrease Calculator

Percentage decrease measures how much a value has reduced.

Formula

Percentage Decrease = ((Original Value - New Value) ÷ Original Value) × 100

Example

Original Price = $500

New Price = $400

Percentage Decrease:

((500 - 400) ÷ 500) × 100

= 20%

The value decreased by 20%.

Percentage Difference Calculator

Percentage difference helps compare two numbers.

Formula

Percentage Difference = Difference ÷ Average × 100

Example

Value A = 80

Value B = 100

Difference = 20

Average = 90

Percentage Difference:

20 ÷ 90 × 100

= 22.22%

Exam Percentage Calculator

Students frequently use percentage calculators to determine academic performance.

Example

Obtained Marks = 850

Total Marks = 1100

Percentage:

(850 ÷ 1100) × 100

= 77.27%

This helps students quickly understand their results.

Discount Percentage Calculator

When shopping online or in stores, percentage calculations help determine discounts.

Example

Original Price = $200

Discount = 25%

Discount Amount:

25 ÷ 100 × 200

= $50

Final Price:

$200 - $50

= $150

The calculator instantly provides both discount amount and final price.

Profit Percentage Calculator

Business owners and entrepreneurs often calculate profit percentages.

Formula

Profit Percentage = (Profit ÷ Cost Price) × 100

Example

Cost Price = $500

Selling Price = $700

Profit = $200

Profit Percentage:

200 ÷ 500 × 100

= 40%

Tax Percentage Calculator

Tax calculations become easier with a percentage calculator.

Example

Product Price = $1000

Tax Rate = 15%

Tax Amount:

15 ÷ 100 × 1000

= $150

Final Price:

$1150
