Disclaimer:
I’m not an expert in finance or investing — none of this is advice in any way.
These are just my personal notes after a few hours of reading and exploring about mutual funds and index investing.
Mutual Funds 101
- Mutual funds pool money from multiple investors and invest it into stocks, bonds, or other securities.
- You can buy mutual funds directly (through Zerodha Coin, Groww, etc.).
- Zerodha offers
, which means no middleman commissions — you keep more of the returns.
Index Funds
- An Index Fund is a type of mutual fund that tracks a
. - Instead of a fund manager picking and choosing which companies to invest in, an index fund simply mirrors a pre-defined list of companies that make up that index.
- So, if Nifty 50 goes up 10%, your index fund roughly goes up 10% (minus a tiny fee).
Side Note: The value of a mutual fund unit (called NAV) naturally moves up and down with the market.
You don’t need to worry about daily changes or how it’s calculated — as long as the companies in your index grow over time, your NAV does too.
Example Index Funds in India (2025)
| Fund Name | Index Tracked | Expense Ratio | Launch Year |
|---|---|---|---|
| HDFC Nifty 50 Index Fund | Nifty 50 | 0.20% | 2002 |
| Axis Nifty 50 Index Fund | Nifty 50 | 0.10% | 2021 |
| UTI Nifty 50 Index Fund | Nifty 50 | 0.17% | 2000 |
| HDFC Sensex Index Fund | Sensex (BSE 30) | ~0.20% | 2002 |
All of them are SEBI-regulated — so you’re safe with any.
Why I Think Index Funds Are a Safe Bet
A small personal note — not advice, just my reasoning.
If I try to pick individual stocks myself, there’s always a huge risk:
- I might be wrong about the company’s future, or the entire industry might slow down.
- Or the opposite could happen — a company I ignored could skyrocket 100x, and I’d miss out completely.
I’m not someone who has the time, patience, or deep financial knowledge to track companies daily, study balance sheets, or predict market trends.
So instead of trying to outsmart the market, I’d rather own the market.
With index funds, the smartest people in finance already decide which companies go into these lists.
If India as a country keeps growing — if businesses innovate, people spend more, and the economy expands — the index will grow too.
That means my portfolio grows along with the country’s progress.
I might not make 100x returns overnight, but I also won’t lose everything on a bad bet.
I’m okay with slower, steadier, predictable growth — because I’m betting on something much bigger than any one company: the collective growth of the entire Indian economy.
Expense Ratio (The Tiny Fee That Matters)
- Every mutual fund charges a small percentage annually to manage the fund — called the expense ratio.
- Example:
- HDFC Nifty 50 Index Fund → 0.20%
- Axis Nifty 50 Index Fund → 0.10%
- This might look small, but over decades, it can create a noticeable difference.
Example:
₹10,000/month SIP for 40 years at 12% annual return
- HDFC (0.20% fee) → ₹9.48 crore
- Axis (0.10% fee) → ₹9.59 crore
→ ~₹11 lakh difference, just from that 0.1% fee difference!
SIP (Systematic Investment Plan)
- SIP = invest a fixed amount every month automatically.
- Super beginner-friendly and removes emotion from investing.
- Works great with index funds — just pick one, start monthly, and don’t stop for years.
SIP Formula (for the math nerd in me)
Where:
| Symbol | Meaning | Example Value |
|---|---|---|
| Monthly investment | ₹10,000 | |
| Effective monthly rate | per month | |
| Total months | ||
| Final corpus | ~₹9.8 crore 😳 |

TL;DR — My Key Takeaways
- Go for index funds (simple, low-cost, steady).
- Start an SIP — ₹10k/month is plenty long term.
- Lower expense ratio = more returns over decades.
- Nifty 50 funds are slightly broader than Sensex funds.
- Everything here is safe, regulated by SEBI, and easy to start via Zerodha Coin.
- Compounding over decades is wild — let it do its thing.
What Got Me Interested (if future me forgets)
These are a few videos and playlists that actually got me curious enough to start reading and writing about all this stuff:
-
🎥 Hasan Minhaj x J.L. Collins — Financial Literacy for Dummies
A really fun and insightful talk between Hasan Minhaj and J.L. Collins (author of The Simple Path to Wealth).
It breaks down the idea of long-term, index-based investing in such a simple, no-nonsense way — this one really stuck with me. -
🎓 Fundfolio by Sharique Samsudheen (YouTube Playlist)
A Malayalam YouTube series by Sharique Samsudheen, who teaches personal finance and investing from an Indian (and Mallu) perspective.
If you understand Malayalam and want to learn about the Indian stock market and personal wealth management in a relatable way — this is probably the best place to start.
I haven’t finished the full course myself, but this was my first real exposure to how the market and investing actually work.
That’s it. Just a shorthand version of my “aha” moment about how money quietly grows if you just stay consistent.
What Are Direct Mutual Funds?
When you invest in a mutual fund, there are actually two ways to do it:
-
Regular Plan → you invest through a middleman (like your bank, broker, or an agent).
- The middleman gets a commission from the fund house for bringing in your investment.
- That commission comes from your returns — meaning you earn a little less.
-
Direct Plan → you invest directly with the fund house (no middleman involved).
- There’s no commission or distribution fee.
- The expense ratio is lower, so more of the returns stay with you.
- Over the long run, this small difference compounds into a lot.
💡 Quick Example
Let’s say you’re looking at the same fund — HDFC Nifty 50 Index Fund:
| Type | Expense Ratio | Who earns the commission | Long-term impact |
|---|---|---|---|
| Regular Plan | ~1.0% | Bank / Agent | You lose a bit every year |
| Direct Plan | ~0.2% | Nobody | You keep that extra 0.8% yourself |
That 0.8% may sound small, but over decades it can easily mean lakhs of rupees in difference — just from avoiding commissions.
🧭 How Zerodha Coin Fits In
Platforms like Zerodha Coin, Groww, and Kuvera let you invest in direct mutual funds. They don’t earn any commission from the fund houses — instead, they might charge a small flat platform fee or, in Zerodha’s case, none at all.
So when you buy mutual funds through Coin, you’re basically investing directly with the fund house — the most cost-efficient and transparent way to invest.
What’s a Market Index?
A market index is basically a curated list of companies that represent how the overall stock market (or a particular sector) is performing.
Think of it like a report card for the economy — if the companies in the index are doing well, it usually means the economy is growing too.
How Market Indexes Work
- Each index is made up of selected companies that best represent a part of the market.
- Companies are chosen based on their market capitalization, liquidity, and trading activity.
- Larger companies get a bigger weight in the index (so their ups and downs influence the index more).
- These lists are reviewed twice a year — usually in March and September — to remove underperformers and add rising stars.
- Indexes are maintained by independent bodies — in India:
- Nifty 50 is managed by the National Stock Exchange (NSE).
- Sensex is managed by the Bombay Stock Exchange (BSE).
Popular Indian Market Indexes
| Index | Managed By | Companies | Represents |
|---|---|---|---|
| Nifty 50 | NSE | Top 50 companies | Broader market coverage |
| Sensex | BSE | Top 30 companies | Smaller but older, historical index |
Together, Nifty 50 and Sensex act as mirrors of India’s corporate growth — when India’s economy grows, these indexes reflect it.
So, when you invest in an index fund that tracks one of these, you’re indirectly investing in the growth of India’s top companies.
