Understanding Percentage Increase and Decrease
Percentage change is one of the most commonly used calculations in everyday life. People use it to compare prices, measure salary changes, analyze investments, and track performance metrics.
Understanding how percentage increase and decrease works helps individuals make better financial and business decisions.
The Percentage Increase Formula
The formula for calculating percentage increase is:
Percentage Increase = (New Value − Original Value) / Original Value × 100
This formula determines how much a value has grown relative to its original amount.
Example Percentage Increase
If the price of a product rises from $50 to $65, the increase can be calculated using the formula.
(65 − 50) ÷ 50 × 100 = 30%
This means the price increased by 30 percent.
Percentage Decrease Formula
Percentage decrease is calculated in a similar way.
Percentage Decrease = (Original Value − New Value) / Original Value × 100
This formula shows how much a value has declined.
