Return on Investment (ROI)
ROI measures the profitability of an investment by comparing the gain or loss relative to its cost. It's expressed as a percentage and helps evaluate the efficiency of different investments.
Key uses: Comparing investment performance, assessing business profitability, evaluating marketing campaigns.

(Current Value - Cost) / Cost × 100
Example Calculation
- Investment Cost: $10,000
- Current Value: $12,500
- ROI: (12,500 - 10,000) / 10,000 × 100 = 25%
Compound Interest
Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods. It's a powerful force that can significantly grow investments over time.
Key factors: Initial investment, contribution frequency, time horizon, interest rate.
