Percentage Increase Formula

Formula:

Percentage Increase = ((New Value − Original Value) / Original Value) × 100%

This tells you what percent the original number grew by.

Enter the new value (ending number)
Click “Calculate”
The calculator will display the percentage increase result

Example Calculation

Original Value: 80
New Value: 100

Percentage Increase: ((100 - 80) / 80) × 100% = 25%

This means the value increased by 25% from the original number.

Percentage Increase: Used when the new value is greater
Percentage Decrease: Used when the new value is smaller
Percentage Change: General term that can be either increase or decrease

More Example Calculations

From 150 to 180 → ((180 − 150)/150) × 100% = 20%
From 200 to 260 → ((260 − 200)/200) × 100% = 30%
From 90 to 100 → ((100 − 90)/90) × 100% ≈ 11.11%

Step-by-Step Breakdown

Let’s say a company’s revenue went from $500,000 to $650,000:

Find the difference: 650,000 − 500,000 = 150,000
Divide by the original: 150,000 / 500,000 = 0.3
Multiply by 100: 0.3 × 100 = 30%

Answer: The company experienced a 30% increase in revenue.

How to Tell if It’s an Increase

If the new value is greater than the original, it’s an increase. If not, it’s a decrease.

Use our for the reverse scenario.

Visualizing Percentage Increase

Businesses often use bar charts, pie charts, and line graphs to visually show how one value has increased over another. The percent increase is often displayed as a label or highlighted metric in dashboards or reports.

Using Percentage Increase in Excel or Sheets

Put original value in cell A1
Put new value in cell B1
Formula: =((B1 - A1)/A1)*100
Format result as a percentage

Applications in Real Life

Salary Increase: From ₹40,000 to ₹50,000 = 25% hike

Always compare the new value to the original
Double-check your input values to avoid reversed results
Use whole numbers or decimals depending on your data format
When comparing percentages themselves, use a calculator

When Not to Use Percentage Increase

There are a few cases where this calculator may not apply:

When comparing two negative numbers
When the original value is zero (undefined result)
When you're analyzing average percent change over multiple time periods (use CAGR instead)

Frequently Asked Questions

Can the percentage increase be negative?

No. If the result is negative, that means it's a percentage decrease. Use the appropriate tool for that case.

Division by zero is undefined, so percentage increase cannot be calculated in this case. Consider using absolute change instead.

Can I compare percentages themselves?

Not directly. Use the for that.
