Change In Percentage Calculator
This powerful yet simple online tool removes the need for manual calculations and provides instant results with accuracy. It is designed for students, professionals, business owners, and anyone who needs to analyze percentage changes efficiently.
What is a Change in Percentage Calculator?
A change in percentage calculator is an online tool that calculates the percentage difference between two values: the original value and the new value. It shows whether the change is positive (increase) or negative (decrease).
The formula used in the background is:
Percentage Change = ((New Value – Original Value) / Original Value) × 100
This helps users understand how much a value has changed relative to its starting point.
For example:
- If a product price increases from $100 to $120, the calculator shows a 20% increase
- If a value drops from 200 to 150, it shows a 25% decrease

Example of Percentage Change Calculation
Let’s understand how the calculator works with real-life examples.
Example 1: Price Increase
- Original Value: $50
- New Value: $75
Calculation:
((75 – 50) / 50) × 100 = 50%
Result: 50% Increase
This means the price has increased by half compared to the original value.
Example 2: Price Decrease

- New Value: 150
Calculation:
((150 – 200) / 200) × 100 = -25%
Result: 25% Decrease
This shows the value has dropped by 25% from the original amount.
Example 3: Business Growth
- Original Sales: 10,000 units
- New Sales: 13,000 units
Calculation:
((13,000 – 10,000) / 10,000) × 100 = 30%
Result: 30% Growth
This indicates a strong increase in business performance.
