Most Important Ratios for Practical Use (Top 5)
If you want a simple shortlist, focus on these:
- Expense Ratio
- Sharpe Ratio
- Alpha
- Beta
- Standard Deviation
These five ratios are widely used to evaluate mutual fund performance and risk-return profile.
1) Expense Ratio (Cost of the Fund)
- Meaning: Annual cost charged by the fund house.
- Why important: Lower cost = higher net returns.
- Rule of thumb:
- Equity active fund: ≤ 2%
- Index fund: ≤ 0.5%
Example:
If Expense Ratio = 1.5%, then ₹1,00,000 investment costs ₹1,500 per year.
Expense ratio shows what percentage of assets is used to cover operating expenses of the fund.
2) Sharpe Ratio (Risk vs Return)
- Meaning: Return earned per unit of risk.
- Why important: Helps compare funds with different risk levels.
- Rule of thumb:
- > 1 = Good
- > 2 = Excellent
A higher Sharpe ratio indicates better risk-adjusted performance relative to the risk taken.
3) Alpha (Extra Return vs Benchmark)
- Meaning: How much the fund beats its benchmark (e.g., Nifty 50).
- Why important: Measures fund manager performance.
- Rule of thumb:
- Positive Alpha = Good
- Negative Alpha = Underperformance
Alpha measures the excess return a fund generates compared to its benchmark index.
4) Beta (Volatility vs Market)
- Meaning: Risk level compared to the market.
- Why important: Shows how much the fund moves when the market moves.
Rule of thumb:
- Beta = 1 → Same as market
- Beta < 1 → Less risky
- Beta > 1 → More risky
Beta indicates the sensitivity of a fund’s returns to market movements.
5) Standard Deviation (SD) (Volatility)
- Meaning: How much returns fluctuate.
- Why important: Measures risk consistency.
Rule of thumb:
- Lower SD → Stable fund
- Higher SD → Risky fund
Higher standard deviation means greater fluctuation in returns and higher risk.
6) Treynor Ratio (Return per Market Risk)
- Meaning: Return earned per unit of market risk.
- Why important: Used to compare diversified portfolios.
Treynor ratio evaluates excess returns generated relative to systematic risk measured by beta.
7) Portfolio Turnover Ratio
- Meaning: How frequently the fund manager buys/sells stocks.
- Why important: High turnover = higher cost and tax impact.
Rule of thumb:
- Low turnover = Long-term strategy
- High turnover = Active trading
Turnover ratio represents the percentage of investments replaced in a fund over a year.
Quick Example (How Advisors Use Ratios)
When comparing two equity funds:
| Ratio | Fund A | Fund B | Better |
|---|---|---|---|
| Expense Ratio | 1.2% | 2.0% | Fund A |
| Sharpe Ratio | 1.4 | 0.9 | Fund A |
| Alpha | 3.0 | 1.5 | Fund A |
| Beta | 0.95 | 1.3 | Depends on risk |
| Std Dev | 14 | 22 | Fund A |
Conclusion: Fund A is generally better (lower risk, better returns).
Here are the ideal ratio values for Equity, Debt, and Hybrid Mutual Funds in India (2026). This is especially useful if you are selecting funds for SIP recommendations or client portfolios.
Ideal Ratio Values by Mutual Fund Category (India)
1) Equity Mutual Funds (Large / Flexi / Midcap)
| Ratio | Ideal Value | What It Means |
|---|---|---|
| Expense Ratio | ≤ 1.5% | Lower cost is better |
| Sharpe Ratio | > 1 | Good risk-adjusted return |
| Alpha | Positive (2–5) | Beating benchmark |
| Beta | 0.9 – 1.2 | Market-level risk |
| Standard Deviation | Lower than category | Stable returns |
| Turnover Ratio | < 60% | Long-term investing |
Example Benchmark
Most equity funds compare themselves to indices like:
- Nifty 50
- BSE Sensex
2) Debt Mutual Funds
| Ratio | Ideal Value | What It Means |
|---|---|---|
| Expense Ratio | ≤ 1% | |
| Sharpe Ratio | > 1 | |
| Credit Rating | AAA / Sovereign | |
| Average Maturity | Depends on goal | |
| Modified Duration | Lower for safety | |
| Standard Deviation | Very Low |
Key Focus for Debt Funds
- Credit quality
- Interest rate risk
- Duration
Debt fund risk is often linked to interest rate movement influenced by the:
- Reserve Bank of India
3) Hybrid / Multi-Asset Funds
| Ratio | Ideal Value | What It Means |
|---|---|---|
| Expense Ratio | ≤ 1.7% | |
| Sharpe Ratio | > 1 | |
| Equity Allocation | 40–75% | |
| Beta | 0.7 – 1 | |
| Standard Deviation | Medium | |
| Turnover Ratio | < 50% |
These funds balance risk using multiple asset classes like equity, debt, and gold.
Most Important Ratios to Check Before Recommending SIP (Practical Checklist)
Use this 5-point quick filter:
- Expense Ratio
- Sharpe Ratio
- Alpha
- Standard Deviation
- AUM (Assets Under Management)
This is the standard screening method used by many advisors and distributors.
Example — Real Fund Screening (Equity Fund)
Let’s say you evaluate a fund benchmark to:
- Nifty 500
Good Fund Indicators:
Expense Ratio: 1.2%
Sharpe Ratio: 1.3
Alpha: +3.5
Beta: 0.95
Std Dev: 15
This typically indicates:
- Competitive cost
- Better risk-adjusted returns
- Moderate volatility
Simple Rule for Fast Decision (Very Practical)
If these 4 conditions are met, the fund is usually strong:
- Expense Ratio is low
- Sharpe Ratio is above 1
- Alpha is positive
- Risk is lower than category average
This works well for SIP selection, client portfolios, and fund comparison.
