Compound Annual Growth Rate (CAGR) is the constant annualized rate at which an investment grows over a period, assuming all profits are reinvested. In India, mutual fund regulators define CAGR as the steady rate that links the beginning and ending value of an investment over time. Regulators actually require mutual funds to show returns in CAGR terms for 1-, 3-, and 5-year periods on fact sheets and ads. Here's what CAGR means, how to calculate it, and when to use it—or when to use XIRR instead.
What is CAGR?
Formally, if an investment grows from a starting amount P to a final amount A in t years, the formula is: CAGR = (A ÷ P)^(1 ÷ t) − 1.
For example, if ₹100 grows to ₹150 over 3 years, then CAGR = (150/100)^(1/3) − 1 ≈ 14.47%. That tells you the investment grew at an average of 14.47% per year. Funds must also show "point-to-point" returns on a standard ₹10,000 investment alongside CAGR.
How to Calculate CAGR (Step by Step)
To compute CAGR: identify the initial value (P), final value (A), and duration (t). Example: ₹10,000 grows to ₹15,000 over 5 years.
- Ratio: A ÷ P = 15,000 ÷ 10,000 = 1.5
- Exponent: 1 ÷ t = 1 ÷ 5 = 0.2
- Annual factor: 1.5^0.2 ≈ 1.0834
- Subtract 1: 1.0834 − 1 = 0.0834
- Convert to %: 0.0834 = 8.34% annualized return
In summary: divide ending value by beginning value, raise to the power of (1 ÷ years), then subtract 1.
Example Calculation
Lump-sum example
- Initial (P): ₹10,000
- Final (A): ₹15,000 after 5 years
- Years (t): 5
CAGR = (15,000 ÷ 10,000)^(1 ÷ 5) − 1 ≈ 8.34% per year
Absolute Return vs CAGR
Absolute return is the simple total percentage gain over a period, without accounting for time. If ₹1,00,000 grows to ₹1,50,000 in 3 years, absolute return = (1,50,000 − 1,00,000) ÷ 1,00,000 × 100 = 50%.
CAGR annualizes that: (1,50,000 ÷ 1,00,000)^(1 ÷ 3) − 1 ≈ 14.47% per year. Absolute return tells you "how much" you gained overall; CAGR tells you "how fast per year." CAGR smooths volatility and ignores interim withdrawals or deposits, which makes it useful for comparing funds over different periods.

CAGR vs XIRR (Lump Sum vs SIP)
CAGR assumes a single, point-to-point investment. It does not account for multiple cash flows (like SIP installments or withdrawals). So CAGR applies to one-time lump-sum investments—not to SIPs, STPs, or any scenario with cash flows at different times.
For multiple contributions or redemptions, use XIRR (Extended Internal Rate of Return). XIRR equates all cash inflows and outflows on their exact dates to the final portfolio value. Fund houses note that "XIRR provides a clearer picture" for SIPs because it considers exact dates and amounts. Use CAGR for lump sum, XIRR for SIPs.
For example, if you SIP ₹15,000 per month for 3 years (total ₹5.4 lakh) and the final value is ₹7.5 lakh, a naïve CAGR would treat it as if ₹5.4L were invested at once—misleading. The correct return for monthly flows comes from XIRR.
Taxation of Mutual Fund Gains
Post-tax returns are lower than raw CAGR. Equity funds (≥65% in equities): 10% LTCG on gains above ₹1 lakh per year; 15% STCG for units held ≤1 year. Debt funds: from April 2023, all gains are taxed at your income slab (short-term). Earlier rules had 20% with indexation for holdings over 3 years. These taxes mean your effective CAGR after tax will be lower.
Why Regulators Require CAGR
SEBI and NISM mandate that mutual fund fact sheets and ads report returns in CAGR terms for 1-, 3-, and 5-year periods. This standardizes how funds present performance so investors can compare schemes on a like-for-like basis. It also helps you set realistic return expectations for long-term planning.
Frequently Asked Questions
- Is CAGR the same as absolute return? No. Absolute return measures point-to-point growth without considering time. CAGR gives the annualized growth rate.
- Can CAGR be negative? Yes. If the final value is lower than the initial investment, CAGR will be negative, indicating a loss.
- Does CAGR include dividends? In mutual funds with the Growth option, dividends are reinvested and reflected in the NAV, so CAGR includes them.
- Can I use CAGR for my SIP? No. CAGR is for lump-sum investments only. For SIPs or any investment with multiple cash flows, use XIRR—and our XIRR Calculator to compute it.
Mastering Your Return Metrics
CAGR is the standard metric for lump-sum mutual fund returns—the average annual growth linking start and end value. Regulators require funds to report it. Use it to compare funds and plan long-term. For SIPs, use XIRR instead. Factor in taxes when judging your real returns. Try our CAGR Calculator to compute returns for any scheme.
