Overview
Percentage change is your go-to metric when you want to feel good or bad about your financial decisions without diving deep into the abyss of numbers. It’s like a financial weighing scale—informative but sometimes alarming.
How to Calculate Percentage Change
Here’s where your old math teacher gets their revenge. To calculate percentage change:
- Identify your values: Start by identifying the initial and final values. Let’s call them the “Before” and “After” figures, like in a weight loss commercial.
- Calculate the difference: Subtract the “Before” from the “After.” If you get a negative number, don’t panic—it just means things went south.
- Divide the difference: Divide the difference by the “Before” number. This fraction tells how much change happened relative to where you started.
- Convert to percentage: Multiply by 100, and voila, you have the percentage change! This number can now tell you exactly how much joy or regret to feel.
Example in Action
Let’s assume you bought a stock at $100 (the “Before”), and it climbed to $120 (the “After”):
- Increase = After - Before = $120 - $100 = $20
- Percentage Increase = ($20 / $100) * 100 = 20%
Congratulations, you’re 20% richer on paper!
Practical Uses of Percentage Change
Percentage change isn’t just for counting blessings or miseries in the stock market; it has broader applications:
- Financial Reporting: Companies use it to report growth or decline in earnings, showing stakeholders the bottom-line trends.
- Economic Indicators: Used by governments to report changes in economic metrics like GDP, unemployment rates, etc.
- Personal Finance: Helps individuals assess their investment performance, budget changes, and much more.
Why It Matters
