🙋 What Is Improvement Percentage?
Improvement percentage tells you how much you’ve improved compared to your original starting point.
If you scored 60 on your last test and got an 80 this time, you didn’t just do better—you improved by a specific percentage. Let’s learn how to figure that out!
✏️ The Formula for Improvement Percentage
Here’s the easy-to-remember formula:
Improvement % = [(New Value - Old Value) ÷ Old Value] × 100This gives you a clear, percent-based number that shows how much you’ve improved.
🧮 Let’s See It in Action
Example 1: Test Score
- Old Score = 60
- New Score = 80
Step 1: Find the difference80 - 60 = 20
Step 2: Divide by the old score20 ÷ 60 = 0.333
Step 3: Convert to a percentage0.333 × 100 = 33.3%
✅ You improved your score by 33.3%!
Example 2: Monthly Sales
- January Sales = $1,000
- February Sales = $1,250
Improvement % = (1,250 - 1,000) ÷ 1,000 × 100 = 25%
✅ Your sales improved by 25% in one month. Great job!
📉 Can You Have a Negative Improvement?
Not exactly. If your new value is less than your old one, you haven’t improved—you’ve had a decrease, not an improvement. In that case, you’d calculate percentage decrease using the same formula.
