• Understanding Return on Investment (ROI):
• ROI represents the gain or loss from an investment, usually as a percentage.
• Components:
  • Income: Interest or dividends.
  • Appreciation/Depreciation: Change in the investment’s value.

Methods to Calculate ROI

1. Absolute Return (Point-to-Point Return):

• Formula: ( \text{Absolute Return} = \frac{\text{(Selling Price - Cost Price)}}{\text{Cost Price}} \times 100 )
• Example: Invested20,000 Grows to42,000:
  ( \text{Absolute Return} = \frac{(42,000 - 20,000)}{20,000} \times 100 = 110\% )
• Limitation: Doesn't consider the time period.

2. Simple Annualized Return:

• Formula: ( \text{Annualized Return} = \frac{\text{Absolute Return}}{\text{Time (years)}} )
• Example:1,00,000 grows to1,24,000 in 3 years:
  • Absolute Return = ( 24\% ).
  • Annualized Return = ( 24\% / 3 = 8\% ).

3. Average Annual Return (AAR):

• Formula:
  ( \text{AAR} = \frac{\text{Sum of Periodic Returns}}{\text{Number of Periods}} )
• Example: Returns: 20%, 25%, 22%, -10%.
  ( \text{AAR} = \frac{(20 + 25 + 22 - 10)}{4} = 14.25\% ).
• Limitation: Doesn’t account for volatility or compounding.

4. Compound Annual Growth Rate (CAGR):

• Formula:
  ( \text{CAGR} = \left( \frac{\text{Ending Value}}{\text{Beginning Value}} \right)^{\frac{1}{\text{Time}}} - 1 )
• Example:10,000 grows to15,000 in 2 years:
  ( \text{CAGR} = \left( \frac{15,000}{10,000} \right)^{1/2} - 1 = 22.47\% ).
• Advantage: Smooths out returns for fluctuating investments.
• Limitation: Doesn’t account for interim volatility.

Advanced Metrics for ROI

5. Rolling Returns:

• Evaluates performance over consistent time frames within a given period.
• Example: NAV of two funds rises differently; rolling returns identify consistent performance beyond absolute/CAGR metrics.

6. Relative Returns:

• Compares investment returns to a benchmark.
• Formula:
  ( \text{Relative Return} = \text{Fund Return} - \text{Benchmark Return} )
• Example: Stock returns 20%; benchmark returns 15.58% Relative Return = +4.42%.

7. Peer Returns:

• Compares an investment with peers in the same sector or asset class.
• Example: SBI stock grows 7%, while HDFC grows 9%. Peer analysis highlights underperformance.

Calculating Returns for Multiple Investments

8. Internal Rate of Return (IRR):

• Used when equal cash flows occur at fixed intervals.
• Formula:
  Use Excel: =IRR(values).
• Example: Invest3,000,6,000,5,000,4,000, and6,500 over 5 years, receive36,000 IRR = 14%.

9. Extended Internal Rate of Return (XIRR):

• Handles uneven or irregular cash flows.
• Formula:
  Use Excel: =XIRR(values, dates).
• Example: Invest50,000; earn dividends at irregular intervals and sell at51,000 XIRR = 4.89%.

Key Points for Smart Investments

• Match Metrics to Goals: Use CAGR for comparison, rolling returns for consistency, and relative/peer returns for benchmarking.
• Consider Time and Risk: Longer investment periods and diversified assets improve outcomes.
• Utilize Tools: Excel functions like IRR and XIRR simplify calculations for complex cash flows.
• Evaluate Performance Regularly: Continuously review and adjust your portfolio to stay aligned with financial goals.
