Systematic Investment Plan (SIP) investments have seen tremendous growth over the last few years, with the latest AMFI data showing over Rs 28,000 crore inflows coming from over 9.11 crore active accounts in July 2025. The SIP mode of investment has been a popular tool since it allows people to start investing with an amount as low as Rs 100. SIPs benefit from market fluctuations through rupee-cost averaging. But strangely, when markets turn volatile, investors grow anxious and many of them stop temporarily or quit SIP.

In this write-up, we will discuss some common mistakes even seasoned investors commit in their mutual fund SIP journey and as a result, they do not get the desired returns. Here, we need to understand one thing clearly – SIP is not a magical plan, but it is the result of proper planning done over a long period. If you do not take care of some fundamentals of mutual fund investing, then chances are high that you won’t succeed.

Let us know here 5 common mistakes that can silently kill you SIP returns.

1. Stopping SIP too early

    The real benefit of SIP comes with time. Despite market fluctuations, running SIP for a long time gives the benefit of compounding and rupee cost averaging. But many people stop SIP midway after seeing a small loss or a fall in the market. By doing this, they are deprived of potential big returns in the future.

    2. Not choosing the right fund

      Often investors start SIP without doing research or just on the advice of friends and relatives. Not every fund is right for every investor. It is important to choose the fund according to your goal, time period and risk tolerance. For example, equity funds are better for long-term goals, while debt or balanced funds are more suitable for short term.

      3. Not increasing the SIP amount

        Many people keep running the same old SIP amount for years. But as your income increases, the SIP amount should also be increased. This is called step-up SIP. Increasing your SIP by just 10-15% every year can increase your corpus manifold in the long run.

        4. Having only a short-term perspective

          Patience is necessary to get big benefits from SIP. If you do SIP for only 2-3 years and expect big returns immediately, then this is a big mistake. The real magic of SIP is seen in a period of 10-15 years or more. Therefore, before investing, decide your goals and keep the time period accordingly.

          5. Not reviewing the portfolio regularly

            Once you start SIP, it is also not right to forget it completely. Market conditions, fund performance and your financial goals can change. In such a situation, review the portfolio at least once a year. If a fund is consistently performing poorly, it is better to make changes by consulting a financial advisor.

            Summing up…

            SIP is a great investment tool, but only when you do it for a long time with discipline and the right strategy. Early closure, choosing the wrong fund, not increasing the amount, taking a short-term view and not reviewing the portfolio — these five mistakes can prevent you from building your dream corpus.

            If you avoid these mistakes and follow SIP with patience and discipline, it can prove to be the most reliable companion to achieve your financial goals.
