| Simple Increase | One-time increase from original to new value | Price increase from $80 to $100 (25%) |
| Compound Increase | Multiple successive increases applied to consecutively updated values | 10% increase followed by 15% increase (26.5% total, not 25%) |
| Continuous Growth | Increase that happens continuously rather than at discrete intervals | Population growth, compound interest with continuous compounding |
Common Mistakes to Avoid
Advanced Applications
Compound Annual Growth Rate (CAGR)
CAGR represents the mean annual growth rate over a specific period longer than one year.
Example: If an investment grows from $1,000 to $1,610 over 5 years, the CAGR is 10%.
Real-World Application Example
Financial Planning Case Study
Consider an investment portfolio that started with $50,000 and grew to $68,000 over 3 years:
- Absolute Increase: $68,000 - $50,000 = $18,000
- Percentage Increase: ($18,000 / $50,000) × 100 = 36%
- Annual Percentage Rate: ((68,000 / 50,000)^(1/3) - 1) × 100 ≈ 10.78%
This information helps the investor understand both the overall performance and the annualized return rate for comparison with other investment options.
