This calculator allows you to find the percentage change between an original value and a new value, indicating either an increase or a decrease. It applies a standard formula to measure how much a quantity has grown or declined relative to its starting point.
How to Use This Tool?
- Enter the original value (A) representing the starting amount
- Input the new value (B) which is the final amount
- Click the calculate button to get the percentage change
- Review the result to see if it reflects an increase or decrease
- Use the value to understand growth or decline in your data
Key Features
- Calculates percentage increase or decrease based on original and new values
- Uses the formula: (B - A) / A × 100 for straightforward percentage change
- Provides precise floating-point calculations
- Suitable for prices, statistics, financial data, and performance metrics
- Fast and easy to use with a clear input interface
Examples
- If a population increases from 12,000 to 15,600, calculate percentage change as ((15,600 - 12,000) / 12,000) × 100 = 30%
- Determining the percentage decline when prices drop from 50 to 40 by applying the formula
- Comparing performance metrics to find how much progress was made using original and new measurements
Common Use Cases

- Unable to calculate cumulative percentage changes over time
- Limited to single-step change assessments between two values
- Does not analyze underlying reasons for the change
- Best suited for quick and straightforward percentage change measurements
Frequently Asked Questions
- How is percentage change calculated?
- Percentage change is calculated using the formula: (B - A) divided by A, then multiplied by 100, where A is the original value and B is the new value.
- What does a positive percentage change indicate?
- A positive percentage change means the new value is higher than the original, indicating an increase.
- Can this tool handle multiple percentage changes over time?
- No, this calculator measures only the percentage difference between two values and does not account for cumulative changes across multiple periods.
Key Terminology
- A (Original value)
- The starting amount or initial value before the change occurs.
- B (New value)
- The final amount or value after the change has taken place.
- Percentage Change
