💡 Practical Examples - How to Calculate Percentage Change

Example 1: Calculate Percentage Increase
Price increased from $50 to $75
Percentage Change = ((75 - 50) / 50) × 100 = 50% increase
Example 2: Calculate Percentage Decrease
Sales dropped from 200 to 150 units
Percentage Change = ((150 - 200) / 200) × 100 = -25% decrease
Example 3: Percentage Growth Calculator
Revenue grew from $10,000 to $12,500
Percentage Change = ((12500 - 10000) / 10000) × 100 = 25% growth

❓ Frequently Asked Questions

How to calculate percentage change between two numbers?
To calculate percentage change between two numbers, use this simple formula: subtract the old value from the new value, divide by the old value, then multiply by 100. For example, if a value changes from 50 to 75, the percentage change is ((75-50)/50)×100 = 50%. Our percentage change calculator does this automatically. This percent change calculator works for both increases and decreases. Use our tool to calculate percent change instantly without manual calculations!
What is the percentage change formula and how does it work?
The percentage change formula is: Percentage Change = ((New Value - Old Value) / Old Value) × 100. This percent change formula calculates the relative change between two values. When learning how to calculate percentage change, remember that a positive result indicates an increase, while a negative result shows a decrease. Our percentage difference calculator applies this percentage change equation automatically. The formula is universal for all percentage calculator operations, whether you're calculating growth, decline, or variance.
How do I calculate percentage increase with this calculator?
To calculate percentage increase, enter your starting value as the initial value and the higher value as the final value. Our percentage increase calculator will automatically compute the increase. For example, if a price rises from $100 to $125, the percent increase is 25%. This increase percentage calculator shows you the exact formula used: ((125-100)/100)×100. The percentage growth calculator feature is perfect for tracking salary increases, investment returns, or price hikes. Simply input your values to find percentage increase instantly!
How to calculate percentage decrease using this tool?
To calculate percentage decrease, enter your starting value as the initial value and the lower value as the final value.

This decrease percentage calculator uses the standard formula: ((150-200)/200)×100. Whether you're tracking percentage drop calculator results, discount calculations, or value reductions, our tool provides accurate percentage decrease calculations every time!
What is percentage difference and how is it calculated?
Percentage difference measures the relative change between an old value and a new value. Our percent difference calculator computes this by finding the difference between two values, dividing by the original value, and multiplying by 100. The percentage variance calculator shows whether values increased or decreased. When you need to calculate percentage difference, simply input both values and our calculator does the rest. This change in percentage calculator is essential for comparing data sets, analyzing trends, or evaluating changes in metrics.
