Understanding Percentage Change
Percentage change quantifies the difference between an initial value and a final value as a proportion of the initial value. It helps us understand the magnitude and direction (increase or decrease) of a change. This is a basic yet powerful calculation used across finance, economics, and even daily life.
For instance, if you bought a stock for $50 and it's now worth $60, you'd want to know the percentage increase to assess your investment's performance. Similarly, when shopping, comparing the original price to the sale price lets you determine the percentage discount.
How to Calculate Percentage Change
The formula for percentage change is straightforward:
Percentage Change = [(New Value - Old Value) / |Old Value|] * 100
Here's a breakdown of the steps:
- Identify the "Old Value" (starting or initial value) and the "New Value" (ending or final value).
- Subtract the Old Value from the New Value.
- Divide the result by the absolute value of the Old Value. This ensures you're comparing the change to the original amount, regardless of whether it's an increase or decrease.
- Multiply by 100 to express the result as a percentage.
A positive percentage indicates an increase, while a negative percentage indicates a decrease.
Real-World Examples
Let's solidify the concept with some examples:
- Price Increase: A loaf of bread cost $2.50 last year and now costs $3.00. The percentage increase is [($3.00 - $2.50) / $2.50] * 100 = 20%.
- Discount Calculation: A jacket originally priced at $100 is on sale for $75. The percentage decrease is [($75 - $100) / $100] * 100 = -25%. This is a handy calculation for determining the actual savings you receive.
- Investment Growth: An investment of $1000 grows to $1150 in a year. The percentage increase is [($1150 - $1000) / $1000] * 100 = 15%.
