CAGR vs Absolute Returns: Why Your Mutual Fund Ads Are Misleading
“This fund gave 150% returns!” screams the advertisement. Sounds incredible. But over what period? If that 150% happened over 10 years, the CAGR is about 9.6%. Suddenly less impressive than your FD.
This is the gap between absolute returns and CAGR, and fund houses exploit it constantly.
Absolute Returns
Absolute return is simple: how much did you gain in total?
Absolute return = (Final value - Initial value) / Initial value x 100
Invested 1 lakh, got back 2.5 lakhs? That’s 150% absolute return. Clean, intuitive, and completely useless without knowing the time period.
CAGR (Compound Annual Growth Rate)
CAGR answers: “What annual rate would have produced this result?”
CAGR = (Final / Initial)^(1/years) - 1
That 150% over 10 years? CAGR = (2.5/1)^(1/10) - 1 = 9.6%.
Same 150% over 5 years? CAGR = 20.1%. Very different story.
How Fund Houses Game This
Trick 1: Using absolute returns for long periods
“Our fund gave 300% returns since inception!” Inception was 12 years ago. CAGR: 12.2%. Good, not godlike.
Trick 2: Cherry-picking time periods
Returns from March 2020 (COVID crash bottom) to any point in 2021 look extraordinary. A fund might show “85% returns in one year” by picking the perfect start date.
Trick 3: Point-to-point vs rolling returns
A fund might have one incredible year in a decade of mediocrity. The 1-year return looks amazing. The 10-year CAGR tells the real story.
Which to Use When
| Metric | Use for |
|---|---|
| Absolute return | Short periods (under 1 year), quick comparisons |
| CAGR | Anything over 1 year, comparing across different time periods |
| Rolling CAGR | Evaluating consistency (e.g., all 5-year windows over 15 years) |
A Real-World Comparison
Two funds, both started with 1 lakh:
Fund A: Grew to 4 lakhs in 10 years
- Absolute return: 300%
- CAGR: 14.9%
Fund B: Grew to 3.5 lakhs in 8 years
- Absolute return: 250%
- CAGR: 17.0%
Fund A has the better absolute return. Fund B has the better CAGR. Fund B is the better investment by any rational measure, because it compounded your money faster.
The Only Number That Matters
When evaluating any investment, convert everything to CAGR. It’s the only metric that lets you compare a 3-year FD to a 10-year equity fund to a 5-year real estate investment on equal footing.
Absolute returns impress. CAGR informs. Make decisions with the latter.
