Calculate percentage increase and decrease between two values. Find the percentage change and absolute difference.
Percentage change measures the degree of change over time and is expressed as a percentage. It's calculated by finding the difference between the new and old values, dividing by the absolute value of the original value, and multiplying by 100. A positive result indicates an increase, while a negative result indicates a decrease.
Percentage Change = ((New Value - Old Value) / |Old Value|) × 100
Positive result: Indicates an increase
Negative result: Indicates a decrease
Zero result: No change

Measure experimental changes, population growth, temperature variations, and data trends.
Absolute change shows the actual difference between values, while percentage change expresses this difference relative to the original value, making it easier to compare changes of different magnitudes.
When the new value is greater than the original value, the result is positive, indicating growth or increase.
When the new value is less than the original value, the result is negative, indicating decline or decrease.
The percentage change depends on which value you use as the base. Always use the original or starting value as the denominator for consistent results.
