How Does a Percentage Increase Calculator Work?

The percentage increase measures how much a value has grown compared to its original amount.

It tells us the rate of growth between two numbers and expresses that growth as a percentage.

For example:

• A salary rises from $2,000 to $2,500
• Sales increase from 500 units to 650 units
• A stock price climbs from $80 to $100
• Website visitors grow from 10,000 to 15,000

Instead of simply saying the value increased, the percentage increase tells us how significant that growth actually is.

For instance:

An increase from 100 to 150 means a growth of 50%.

An increase from 1,000 to 1,050 means a growth of only 5%.

Even though both values increased by 50, their percentage growth is very different.

Percentage Increase Formula

The standard formula for calculating percentage increase is:

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

This formula works for almost every percentage increase problem.

Understanding the Formula

The formula consists of three simple steps:

Step 1: Find the Difference

Subtract the original value from the new value.

Difference = New Value − Original Value

Step 2: Divide by the Original Value

Divide the difference by the original amount.

Step 3: Multiply by 100

Multiply the result by 100 to convert it into a percentage.

The final answer represents the growth percentage.

How to Calculate Percentage Increase Step by Step

Let’s look at a practical example.

Suppose a company’s monthly revenue increased from $8,000 to $10,000.

Step 1: Find the Increase

10,000 − 8,000 = 2,000

Step 2: Divide by the Original Value

2,000 ÷ 8,000 = 0.25

Step 3: Multiply by 100

0.25 × 100 = 25%

The company’s revenue increased by 25%.

Percentage Increase Examples

Examples make the concept much easier to understand.

Example 1: Salary Increase

Old Salary = $3,000

New Salary = $3,600

Increase:

3,600 − 3,000 = 600

Percentage Increase:

(600 ÷ 3,000) × 100

= 20%

Your salary increased by 20%.

Example 2: Product Price Increase

Original Price = $50

New Price = $65

Difference:

65 − 50 = 15

Percentage Increase:

(15 ÷ 50) × 100

= 30%

The product price increased by 30%.

---

Example 3: Website Traffic Growth

Previous Visitors = 20,000

Current Visitors = 28,000

Increase:

28,000 − 20,000 = 8,000

Percentage Increase:

(8,000 ÷ 20,000) × 100

= 40%

Website traffic grew by 40%.

---

Example 4: Student Performance

Last Semester Score = 70

Current Score = 84

Difference:

84 − 70 = 14

Percentage Increase:

(14 ÷ 70) × 100

= 20%

The student’s score improved by 20%.

Percentage Increase vs Percentage Change

Many people confuse percentage increase with percentage change.

Percentage change includes both:

• Increase
• Decrease

Percentage increase only refers to positive growth.

For example:

100 to 80

= Percentage decrease

Percentage change is a broader concept.

Percentage increase is specifically used when values rise.

Percentage Increase vs Absolute Increase

These two concepts are different.

Absolute Increase

Simply measures the numerical difference.

Example:

500 to 700

Absolute increase:

700 − 500

= 200

Percentage Increase

Percentage Increase:

(200 ÷ 500) × 100

= 40%

Absolute increase tells us how much something increased.

Percentage increase tells us how significant that increase is.

Both are important depending on the situation.
