Ever wondered how to accurately measure growth, decline, or any kind of change? Calculating percentage differences is a crucial skill, applicable everywhere from tracking stock performance to understanding marketing campaign results.
So, how do you do it? It's simpler than you think! The formula is: `[(New Value - Old Value) / Old Value] * 100`. Let's break it down:
1. **Find the difference:** Subtract the old value from the new value.
2. **Divide by the original:** Divide that difference by the *original* (or older) value.
3. **Multiply by 100:** Multiply the result by 100 to express it as a percentage.
For example, if your website traffic increased from 1000 to 1500, the percentage change is `[(1500-1000)/1000] * 100 = 50%`. A positive result indicates an increase, while a negative result indicates a decrease. Master this simple formula, and you'll be a percentage pro in no time! Now go forth and calculate!
