Calculate Percent Change Now! →What is Percent Increase and Decrease?
Percent increase represents the relative change when a value goes up. For example, if a product's price increases from $50 to $60, you can calculate the percent increase to understand the magnitude of the price hike.
Percent decrease, conversely, shows the relative change when a value goes down. If a stock's value drops from $100 to $70, you can calculate the percent decrease to see how much value was lost.
How to Calculate Percent Increase and Decrease Manually
While our calculator offers instant results, it's helpful to understand the underlying formulas:
- Percent Increase: ((New Value - Original Value) / Original Value) * 100
- Percent Decrease: ((Original Value - New Value) / Original Value) * 100
Let's illustrate with examples:
- Example 1: A store increased its sales from 500 units to 625 units. What is the percent increase?
- Increase = 625 - 500 = 125
- Percent Increase = (125 / 500) * 100 = 25%
- Example 2: A company reduced its workforce from 150 employees to 135 employees. What is the percent decrease?
- Decrease = 150 - 135 = 15
- Percent Decrease = (15 / 150) * 100 = 10%
Common Applications of Percent Increase and Decrease
- Finance: Analyzing investment growth or loss.
- Retail: Calculating discounts and markups.
- Statistics: Tracking population growth or decline.
- Science: Measuring changes in experimental data.
