Percentage change represents the degree to which a number changes over time. It's used extensively to measure the relative difference between two values. A positive percentage change indicates an increase, while a negative percentage change signifies a decrease. Knowing how to calculate percentage change between two numbers allows you to quantify growth or decline, providing valuable insights for informed decision-making.
The Formula and Calculation
The basic formula to calculate percentage change between two numbers is as follows:
Percentage Change = [(New Value - Old Value) / Old Value] * 100
- Determine the Old Value and the New Value: Identify the starting and ending values you want to compare.
- Calculate the Difference: Subtract the Old Value from the New Value.
- Divide by the Old Value: Divide the result by the Old Value.
- Multiply by 100: Multiply the result by 100 to express it as a percentage.
Let's look at some examples:
- Example 1: Increase A stock price increases from $50 to $75. The percentage change is [($75 - $50) / $50] * 100 = 50%. This indicates a 50% increase in the stock price.
- Example 2: Decrease A product's price decreases from $100 to $80. The percentage change is [($80 - $100) / $100] * 100 = -20%. This signifies a 20% decrease in the product's price.
