Understanding and Using a Percentage Change Calculator
A percentage change calculator is a simple yet powerful tool that quantifies the change between two numbers, expressing the difference as either an increase or a decrease. Whether you’re tracking sales growth, monitoring price fluctuations, or measuring performance improvements, this calculator helps you quickly see how much a value has changed relative to its starting point.
What Is a Percentage Change Calculator?
A percentage change calculator takes an “old” or “initial” value and compares it with a “new” or “final” value. By applying the formula below, you can calculate the percentage change:
Percentage Change = ((New Value – Old Value) / |Old Value|) × 100
When to Use a Percentage Change Calculator
Use a percentage change calculator when you need to compare two numbers where the starting value is important. This tool is ideal for:
- Tracking financial growth or declines
- Analyzing changes in metrics like website traffic or conversion rates
- Comparing performance over time in business or personal projects
If you simply need to compare two numbers without a starting point, consider using a percent difference calculator instead.
