How do you choose a mutual fund?
Pick the category first, based on how many years away your goal is. Then compare funds in it on 5-year consistency, Direct-plan expense ratio, manager tenure, fund size, crash drawdown and overlap with what you already own. Star ratings, NAV price and NFOs are mostly noise.
It can feel harder than that. There are nearly 2,000 mutual fund schemes in India (1,985 at the end of August 2026, per AMFI). Every finance influencer recommends a different fund. Star ratings change every quarter. New NFOs launch every month with "exciting" themes. No wonder most investors either pick randomly or just go with whatever their bank relationship manager suggests.
But picking a good fund is simpler than it looks. The 7 checks below cover what matters.
1. Match the Category to Your Goal
Before comparing funds, you need to pick the right category. This matters more than which specific fund you pick within that category.
- Goal is 3-5 years away? → Large cap or balanced advantage fund
- Goal is 5-7 years away? → Flexi cap or large + mid cap combination
- Goal is 7+ years away? → Mid cap, small cap, or aggressive flexi cap
- Goal is 1-3 years away? → Debt fund (short term or corporate bond)
- Emergency fund? → Liquid fund
The wrong category with the right fund will still give you bad results. A small cap fund, even the best one, is wrong for a goal 2 years away.
2. Check 5-Year Returns (Not 1-Year)
One-year returns are meaningless. A fund that was #1 last year could be #50 next year, and often is. What matters is consistency over 5 years.
Here's the check:
- Look at 1-year, 3-year, and 5-year returns
- The fund should be in the top 25% (top quartile) across all three periods
- A fund that's #1 in 1Y but #40 in 5Y probably had one lucky year, so be wary of it
- A fund that's consistently #10-15 across all periods is actually more reliable than a fund that swings between #1 and #50
You can check this on Value Research or Morningstar India — both are free.
3. Check the Expense Ratio
The expense ratio is the annual fee the fund charges you. It's deducted daily from your NAV, so you never "see" it, but it compounds against you every year.
What's a good expense ratio?
| Fund Category | Acceptable Range (Direct Plan) | Red Flag Above |
|---|---|---|
| Index Fund | 0.10% - 0.20% | 0.30% |
| Large Cap | 0.30% - 0.70% | 1.00% |
| Mid Cap | 0.40% - 0.80% | 1.00% |
| Small Cap | 0.40% - 0.80% | 1.00% |
| Flexi Cap | 0.40% - 0.80% | 1.00% |
| Debt Fund | 0.10% - 0.40% | 0.50% |
Always use Direct Plans. Regular plans have higher expense ratios (1.5-2.5%) because they pay commission to distributors. The same fund in Direct vs Regular can differ by ₹5-15 lakh over 20 years.
4. Check How Long the Fund Manager Has Been There
A mutual fund's track record belongs to the fund manager, not the fund name. If the manager who generated those great 5-year returns just left last month, those returns are irrelevant for your decision.
Check:
- Has the current fund manager been running this fund for at least 3 years?
- If the manager changed recently, treat the fund as having no proven track record
- Frequent manager changes at a fund house are a yellow flag
5. Check Fund Size (AUM) for the Category
AUM (Assets Under Management) is the total money the fund manages. It matters differently for different categories:
- Large cap: AUM doesn't matter much. These funds buy highly liquid stocks. ₹50,000 Cr AUM is fine.
- Mid cap: AUM above ₹30,000-40,000 Cr starts limiting the manager's ability to buy/sell mid cap stocks without moving prices. Prefer smaller.
- Small cap: AUM above ₹15,000-20,000 Cr is a red flag. The fund can't deploy that much money effectively in small stocks.
- Debt fund: Larger AUM is better, because it means more stability and less impact from any single investor redeeming.
6. Check How Far It Fell in Past Crashes
Everyone talks about returns. Almost nobody talks about how much the fund fell during crashes. This is called "maximum drawdown" and it's crucial for your ability to stay invested.
Check the March 2020 crash data:
- How much did the fund fall peak-to-trough?
- How did it compare to its category average?
- How quickly did it recover?
A fund that fell 25% when its category fell 35% has genuine risk management skill, even if its upside returns are slightly lower. You're more likely to stay invested in a fund that doesn't panic you during crashes.
7. Check Portfolio Overlap With Funds You Already Own
If you hold 3 funds and all three have Reliance, HDFC Bank, and Infosys in their top 10 holdings, you're not diversified. You own the same stocks three times and pay three expense ratios.
Check:
- Use Value Research's "Portfolio Overlap" tool to compare your funds
- If two funds have more than 40-50% overlap, you don't need both
- Common trap: holding a Nifty 50 index fund AND a large cap active fund, which buy almost the same stocks
What Not to Rely On
These look important but are mostly noise:
- Star ratings: They change every quarter. A 5-star fund today could be 3-star next quarter. They're backward-looking, not predictive.
- NFOs (New Fund Offers): A new fund has zero track record. There's no reason to invest in an NFO when thousands of funds with 5-10 year track records exist.
- NAV price: "This fund's NAV is ₹15 so it's cheap" is completely wrong. NAV has nothing to do with whether a fund is cheap or expensive. A ₹500 NAV fund and a ₹15 NAV fund can give identical returns.
- Theme/sector funds: "AI fund", "EV fund" and "PSU fund" are mostly marketing products. By the time a theme becomes a fund, the stocks are already expensive. Stick with diversified categories.
- IDCW (dividend) option: Payouts under the IDCW option (Income Distribution cum Capital Withdrawal, formerly called "dividend") are just your own money returned to you, and are taxed at your slab rate. Always choose the Growth option.
A Simple Selection Framework
For any fund category, follow this 3-step filter:
- Filter by category → Pick the right category for your goal's time horizon
- Shortlist on consistency → Take about 10 funds that sit in the top quartile across 1, 3 and 5 years, not just the top 5-year number
- Apply the 7 checks above → The 2-3 funds that pass all checks are your candidates
Among those 2-3, just pick any one. The difference between the #3 and #7 fund in a category is far less important than the difference between being invested and not being invested.
Using FinPlann for This
When you use the FinPlann financial planner, it works out how much each goal needs every month and the gap to close. It doesn't pick funds for you: use the checks above to compare them, or ask a SEBI-registered investment adviser.
Run your numbers: check any fund's real returns from its AMFI NAV history in the mutual fund portfolio analyzer, and measure your own SIP return with the XIRR calculator.
Run your numbers: to test a shortlisted fund on consistency and drawdown, load its AMFI NAV history into the mutual fund portfolio analyzer. For funds you already hold, the XIRR calculator gives your actual SIP return.
