CAGR vs XIRR: ఏది మంచిది? 📊🔢
CAGR అంటే ఏమిటి? 📈
CAGR = Compound Annual Growth Rate
Definition: ఒక investment యొక్క average annual growth rate ని calculate చేసే method. ఇది lump sum investment కోసం use చేస్తారు.
CAGR Formula:
CAGR = [(Final Value ÷ Initial Value)^(1/Number of Years)] - 1
Example:
Investment: ₹1,00,000 (Jan 2020)
Current Value: ₹1,50,000 (Jan 2024)
Time Period: 4 years
CAGR = [(1,50,000 ÷ 1,00,000)^(1/4)] - 1
CAGR = [1.5^0.25] - 1
CAGR = 1.107 - 1 = 0.107
CAGR = 10.7% per year
XIRR అంటే ఏమిటి? 📊
XIRR = Extended Internal Rate of Return
Definition: Multiple cash flows ఉన్న investments కోసం use చేసే return calculation method. ప్రధానంగా SIP investments కోసం accurate.
XIRR Features:
- Different dates లో cash flows handle చేస్తుంది
- SIP, lump sum combination కోసం perfect
- Exact timing of investments consider చేస్తుంది
Example:
SIP Investment Pattern:
Jan 2022: ₹10,000
Feb 2022: ₹10,000
Mar 2022: ₹10,000
... (continuing monthly)
Dec 2024: Current Value ₹4,50,000
XIRR calculation considers each SIP date and amount
Result: XIRR = 18.5% (hypothetical)
Key Differences 🔄
CAGR Characteristics:
✅ Single investment date
✅ Single withdrawal date
✅ Simple calculation
✅ Lump sum investments కోసం ideal
✅ Easy to understand
XIRR Characteristics:
✅ Multiple investment dates
✅ Multiple cash flows
✅ Complex calculation (Excel function needed)
✅ SIP/SWP investments కోసం ideal
✅ More accurate for real scenarios
When to Use Which? 🎯
Use CAGR When:
- One-time investment (lump sum)
- Fixed deposit returns
- Stock purchase and hold
- Mutual fund lump sum investment
- Simple comparison needed
Use XIRR When:
- SIP investments (monthly/quarterly)
- Multiple investments at different times
- Portfolio with additions/withdrawals
- Real-life investment scenarios
- Accurate return calculation needed
Real Examples Comparison 💡
Example 1: Lump Sum Investment
Scenario: ₹5 lakhs invested in Nifty 50 fund
Investment Date: 1st Jan 2020
Redemption Date: 31st Dec 2023
Final Value: ₹7.5 lakhs
CAGR Calculation:
CAGR = [(7.5 ÷ 5)^(1/4)] - 1 = 10.67%
XIRR Calculation:
Cash Flow: -5,00,000 (1-Jan-2020)
Cash Flow: +7,50,000 (31-Dec-2023)
XIRR = 10.67%
Result: Both CAGR and XIRR same for lump sum!
Example 2: SIP Investment
Scenario: ₹10,000 monthly SIP for 3 years
SIP Details:
Monthly Investment: ₹10,000
Duration: 36 months
Total Invested: ₹3,60,000
Final Value: ₹4,20,000
CAGR Calculation (Wrong Method):
CAGR = [(4,20,000 ÷ 3,60,000)^(1/3)] - 1 = 5.13%
This is incorrect because money wasn't invested on day 1
XIRR Calculation (Correct Method):
Each SIP date and amount considered
XIRR = 12.5% (actual returns)
Result: XIRR gives accurate picture for SIP!
Example 3: Mixed Investment Pattern
Scenario: Combination of lump sum + SIP
Jan 2022: ₹2,00,000 (lump sum)
Feb 2022 onwards: ₹20,000 monthly SIP
Duration: 24 months
Total Invested: ₹6,80,000
Current Value: ₹8,50,000
CAGR: Cannot calculate accurately
XIRR: 15.8% (considers all cash flows with dates)
Result: Only XIRR can handle this scenario!
Excel/Google Sheets Calculation 💻
CAGR Formula in Excel:
=POWER(Final Value/Initial Value, 1/Years) - 1
Example:
=POWER(150000/100000, 1/4) - 1
Result: 10.67%
XIRR Formula in Excel:
=XIRR(Cash Flows, Dates)
Setup:
Column A: Cash Flows (-10000, -10000, ..., +420000)
Column B: Dates (01-Jan-2022, 01-Feb-2022, ..., 31-Dec-2024)
Formula: =XIRR(A:A, B:B)
Common Mistakes ❌
CAGR Mistakes:
- SIP returns కోసం CAGR use చేయడం
- Multiple investments ignore చేయడం
- Market timing effect not considering
XIRR Mistakes:
- Wrong date format in Excel
- Positive/negative cash flows confusion
- Incomplete data with missing transactions
Example of Wrong Analysis:
Wrong: SIP లో CAGR calculation
₹10,000 monthly SIP for 2 years
Total Invested: ₹2,40,000
Final Value: ₹2,80,000
Wrong CAGR = [(2,80,000/2,40,000)^(1/2)] - 1 = 8.01%
Correct XIRR Calculation:
Considers monthly SIP timing
Correct XIRR = 14.5%
Difference: 6.5% error in return calculation!
Practical Applications 🎯
Mutual Fund Analysis:
SBI Bluechip Fund Analysis:
Investment Type: Monthly SIP ₹5,000
Period: 5 years
Use: XIRR (not CAGR)
HDFC Top 100 Fund:
Investment Type: Lump sum ₹2,00,000
Period: 3 years
Use: CAGR (both CAGR and XIRR same)
Portfolio Performance:
- Overall portfolio: Use XIRR (multiple investments)
- Individual stocks: Use CAGR (if bought once)
- Systematic plans: Always use XIRR
Comparison Studies:
Fund A: XIRR = 15.5% (SIP based)
Fund B: CAGR = 16.2% (lump sum based)
Direct comparison wrong!
Convert both to same investment pattern for comparison
Advanced Concepts 📊
Modified XIRR:
- Weighted average returns consideration
- Cash flow timing optimization
- Tax impact adjustment
Rolling Returns:
3-Year Rolling XIRR Analysis:
2019-2022: XIRR = 12.5%
2020-2023: XIRR = 14.2%
2021-2024: XIRR = 13.8%
Consistency check for investment quality
Inflation-Adjusted Returns:
Real XIRR = [(1 + XIRR) ÷ (1 + Inflation)] - 1
Example:
XIRR = 15%
Inflation = 6%
Real XIRR = [(1.15 ÷ 1.06)] - 1 = 8.49%
