Ever wondered if you could invest even with your last ₹100 by the end of the month? Well, you absolutely can. Passive funds such as the Nifty 100 Index Fund make the stock market accessible, and many allow you to invest with ₹100 as a starting point. The Nifty 100 index is a “diversified investing basket” of India’s top 100 companies by market capitalization across varied sectors of the Indian economy. Investing in this index would mean owning a bit of everything,¬ from banks and tech firms to consumer brands.
Before you start, you should know that like any equity investment, there are Nifty 100 Index Fund risks such as market volatility, tracking error etc..
Now, let’s explore why starting small makes sense, how to begin investing in a Nifty 100 Index Fund, and some of the pitfalls to watch out for.
Why Start Small?
Thanks to the micro-SIP revolution, you don’t need a big bank account to invest. Axis Mutual Fund, that offers index funds at low-cost let investors put in as little as ₹100 per month. This low minimum investment removes the psychological barrier of having to save a large lump sum to start your journey. Essentially, it eliminates excuses we tend to make for not starting our investment journeys, like not having enough money to invest.
Starting small helps develop the discipline of investing regularly. For instance, by starting small via SIP investing (Systematic Investment Plans), you can invest a chosen amount from your bank account at your preferred intervals. Over time, these small contributions can potentially compound. This approach also leverages rupee cost averaging: here, you continue to buy units through market ups and downs, which not only reduces the emotional urge to time the market but also averages out your total cost.
Starting small can also ensure that you are able to sustain your habit of investing, rather than investing heavily in one month and not investing at all in the next.
Moreover, starting small is better than not starting at all and missing out growth opportunities. For instance, as of 30th Sep 2025, the Nifty 100 index has delivered an annualised return of 18.65% in last 5 years and 16.87% CAGR since inception (Inception date 1 December, 2005).(For scheme performance refer below performance table)
Steps to Start Investing
1. AMC or fund house websites: Asset management companies like Axis Mutual Fund allow you to directly invest via their websites or mobile apps in this case you don’t even required demat. Alternatively, you can open a demat and trading account with a broker. Keep your PAN and Aadhaar card handy for eKYC formalities.
2. Choose a fund: Choose a Nifty 100 Index Fund for example Axis Nifty 100 Index Fund. As these passive index funds aim to replicate the benchmark index, they don’t need extensive research. The investment is done in the same proportions as the index. This structure helps passive funds keep their expense ratios lower than active funds. Hence, remember to check the expense ratio and tracking error before you invest.
3. Set up a SIP: Decide how much you can invest regularly. Even though many index funds allow ₹100 monthly SIPs, you can choose an amount that you feel comfortable with. There is no maximum limit. Set up the SIP through your bank’s auto-debit or UPI.
4. Monitor your investments: Review the performance of your fund every quarter or so to ensure that the performance stays close to the index.
Tips for Small Investors
• Stay consistent: The power of compounding works best when you invest regularly. Even when markets dip, it makes sense to continue your SIP as it can buy more units for the same investment amount. Index investing isn’t a get rich quick scheme. Large cap indices like the Nifty 100 Index are designed for potential long-term returns.
• Avoid timing the market: Trying to buy at the “bottom” and sell at the “top” is nearly impossible because you can never know in advance what would be the market bottom and peak. Passive investing thrives on staying invested; the fund continues to mirror the index regardless of market noise. This can help you avoid any hasty decisions made with emotional and human biases.
• Index funds risk and return: These funds are not completely risk-free. The companies that constitute the Nifty 100 index are susceptible to changes in factors like economic downturns, geopolitical changes, or regulatory changes. However, a 5-7 year horizon helps smooth out market volatility and also help maximize long-term returns.
