Calculate the percentage change between two values. Determine whether it's an increase or decrease and get detailed step-by-step calculations.
Where:
Increase Example:
From 100 to 125: ((125-100)/100) × 100 = 25% increase
Decrease Example:
From 100 to 75: ((75-100)/100) × 100 = 25% decrease

Analyze inflation rates, population changes, and economic indicators.
Order Matters: Always use the original (starting) value as the denominator, not the new value.
Zero Original Value: Cannot calculate percentage change when the original value is zero.
Interpretation: A 100% increase means the value doubled, while a 50% decrease means the value halved.
Maximum Decrease: The maximum possible percentage decrease is 100% (when the new value becomes zero).
To calculate percentage change: (1) Find the difference between new and original values, (2) Divide by the original value, (3) Multiply by 100. Formula: ((New Value - Original Value) / Original Value) × 100.
