Formula Behind the % Growth Calculator
The calculator uses this standard growth formula: Percentage Growth=(New Value−Old Value)Old Value×100\text{Percentage Growth} = \frac{(\text{New Value} – \text{Old Value})}{\text{Old Value}} \times 100Percentage Growth=Old Value(New Value−Old Value)×100
For example:
If your sales grew from $5,000 to $6,500, your growth rate would be: (6500−5000)5000×100=30%\frac{(6500 – 5000)}{5000} \times 100 = 30\%5000(6500−5000)×100=30%
That means your business grew by 30% during that period.
Example: How It Works in Practice
Let’s look at a few real-world examples:
Example 1 – Business Growth
- Old Value: $50,000
- New Value: $60,000
(60,000−50,000)50,000×100=20%\frac{(60,000 – 50,000)}{50,000} \times 100 = 20\%50,000(60,000−50,000)×100=20%
✅ Your revenue has grown by 20% compared to the previous period.
Example 2 – Population Growth
- Old Value: 2,000,000
- New Value: 2,080,000
(2,080,000−2,000,000)2,000,000×100=4%\frac{(2,080,000 – 2,000,000)}{2,000,000} \times 100 = 4\%2,000,000(2,080,000−2,000,000)×100=4%
✅ The population increased by 4% in one year.
Example 3 – Investment Growth
- Old Value: $10,000
- New Value: $11,500
(11,500−10,000)10,000×100=15%\frac{(11,500 – 10,000)}{10,000} \times 100 = 15\%10,000(11,500−10,000)×100=15%
✅ Your investment portfolio grew by 15% over the year.
These examples show how versatile this tool is — from finance to personal growth tracking.
