For most goals, a low-cost index fund as the core (roughly 70–100% of your equity money) is a sound default, with an active fund as an optional satellite of 0–30%. The right mix depends on cost, your discipline and how long the goal is, not on last year's ranking.
An index fund simply copies a market index. An active fund tries to beat it, and charges more for trying. The gap in yearly cost looks small, but it compounds.
| Index fund | Active fund | |
|---|---|---|
| Goal | Match the index | Beat the index |
| Typical yearly cost | Low (often well under 0.5%) | Higher (often around 1–2%) |
| Outcome range | Narrow, close to the market | Wide, can beat or trail |
| Manager risk | None | Real |
Illustration (an assumption, not a promise): if the market gives about 12% before costs, a 0.3% cost leaves ~11.7% and a 1.5% cost leaves ~10.5%. On ₹10,000 a month for 20 years that is roughly ₹1.0 crore vs ₹0.85 crore, a difference of about ₹15 lakh from cost alone. An active fund must beat the index by more than its extra cost just to break even.
Across many markets, a large share of active funds trail their index over long periods once costs are counted, and the ones that do win rarely repeat every year. Indian large-cap segments have tended to be hard to beat consistently. Mid and small-cap segments are less efficient, so skilled active management has had more room there, but the spread between good and poor funds is also wider.
The takeaway: picking a winner in advance is hard, so the safer base is the market itself.
Keep the number of holdings small. Two or three funds per goal is plenty.
Whichever you choose, the fund is only a tool. The goal sets the amount, the date and the equity/debt/gold mix, and that mix should de-risk as the goal nears. A separate SIP per goal, linked to a real mutual-fund SIP, keeps each rupee accountable. This is educational, not personal advice; taxes and exit loads change, so check current rules or a CA before switching.
Q. Do index funds guarantee market returns?
A. No. They track the index minus a small cost and a tiny tracking difference. They also fall when the market falls.
Q. Is a lower expense ratio always better?
A. For the same index, yes. Compare tracking difference too, because a cheap fund that tracks poorly can cost you more.
Q. Can I switch from active to index?
A. You can, but selling triggers tax and possibly an exit load under current rules. Redirect new SIPs first and review old units with a CA.
Q. How often should I review?
A. Once a year is enough. Judge an active fund over 3–5 years, not on one bad quarter.
