How to Evaluate Mutual Funds for SIP Investment
To evaluate a mutual fund for SIP investment, look at three things: long-term returns (3-year and 5-year CAGR), risk (NAV volatility), and consistency (whether the fund delivered positive returns across multiple time periods). A good SIP fund should have 12%+ annualised 5-year returns, moderate volatility below 18%, and a consistency score of 2 or 3 out of 3.
What makes a good mutual fund?
A good mutual fund for SIP investment balances returns with risk. High returns that come with extreme volatility can cause investors to panic-exit during corrections, defeating the purpose of SIP. The best SIP funds deliver solid long-term returns with manageable drawdowns.
Rather than chasing the highest 1-year return, focus on consistency — funds that perform well across different market conditions, not just during bull runs.
Key metrics: Returns, Volatility, Consistency
Returns (1Y, 3Y, 5Y CAGR)
Compound Annual Growth Rate over different time horizons. For equity mutual funds, 12-15% annualised over 5 years is good, above 18% is excellent. For debt funds, 6-8% is typical. Always prioritise longer-term returns (3Y and 5Y) over short-term (1Y) for SIP decisions.
NAV Volatility
Measures the fund’s daily price fluctuation as an annualised standard deviation. Below 12% is low risk (typical for debt and hybrid funds), 12-20% is moderate (balanced equity funds), and above 20% is high risk (small-cap, sectoral funds).
Consistency Score (0-3)
Counts positive-return periods across 1Y, 3Y, and 5Y. A score of 3 means the fund delivered positive returns in all three periods — the gold standard for SIP investments. Funds scoring 0 or 1 have been inconsistent performers.
How to screen mutual funds systematically
Instead of reading fund recommendations, build a screening strategy with clear criteria. A good starting screen for equity SIP:
- 5-Year Return above 12% (high importance)
- 3-Year Return above 10% (high importance)
- NAV Volatility below 18% (medium importance)
- Consistency Score of at least 2 (high importance)
- Current NAV — no specific threshold, but useful context
Adjust thresholds based on the fund category. Small-cap funds will naturally have higher volatility and returns than large-cap funds.

FAQ
What makes a good mutual fund for SIP?
A good SIP fund consistently delivers positive returns over multiple market cycles. Look for funds with 12%+ annualised 5-year returns, NAV volatility below 18%, and a consistency score of at least 2 out of 3 (positive returns in most time periods). Fund category matters too — equity funds suit long-term SIPs, debt funds suit short-term goals.
What is NAV volatility and why does it matter?
NAV volatility measures how much a fund's daily Net Asset Value fluctuates, expressed as an annualised standard deviation. Higher volatility means bigger ups and downs. For SIP investors, lower volatility (below 15%) means smoother returns and less anxiety during market corrections.
How is the consistency score calculated?
The consistency score (0-3) counts how many time periods — 1 year, 3 years, and 5 years — the fund delivered positive returns. A score of 3 means positive returns across all three periods, indicating reliable performance. A score of 0 or 1 suggests inconsistent or poor performance.
Should I only look at past returns when choosing a mutual fund?
No. Past returns are important but not sufficient. Also consider the fund's volatility (risk), expense ratio, fund manager track record, and AUM (assets under management). A fund with slightly lower returns but much lower volatility may be a better SIP choice.
