Why Your Mutual Fund SIP Returns May Moderate Over Time

A study of 12 active equity funds reveals that while short-term returns can hit 20%, long-term SIP performance often settles into a 13-17% range. Investors often mistake recent market bull runs for sustainable growth, which can lead to planning failures. Learn why setting realistic return expectations is key to reaching your financial goals.

What Happened

A recent analysis of 12 active equity mutual funds has highlighted a critical reality for long-term investors: performance tends to moderate over time. While short-term gains over three to five years often show impressive figures, sometimes climbing above 20%, the data over a 20-year period paints a more grounded picture. Across these 12 funds, long-term SIP (Systematic Investment Plan) returns have settled in the 13-17% range. This study serves as a reality check for investors who may be using recent market highs to project their future wealth.

The Trap of Short-Term Expectations

It is common for investors to look at a fund that has delivered 20-25% returns over the last few years and assume that this growth rate will continue for the next two decades. However, this is a dangerous assumption. For example, the Nippon India Growth Mid Cap fund showed a 10-year SIP return of 20.28%, but this figure moderated to 16.98% over a 20-year horizon. Similarly, the ICICI Prudential Infrastructure Fund saw its 10-year SIP returns of 20.87% adjust to 14.92% over two decades. Lump-sum investments also follow this trend, with the strongest growth often captured during shorter, high-performance market phases.

Why Long-Term Returns Often Moderate

There are a few business and market reasons why this happens. Markets go through cycles of booms, busts, and flat periods. Short-term performance figures often capture only the "boom" phase, making the fund look exceptionally strong. Over 20 years, a fund must endure multiple economic downturns and periods of slow growth. This process naturally brings the average return closer to the long-term historical performance of the broader market. It is not necessarily a sign of a bad fund, but rather the reality of how compounding works over multiple decades across changing economic environments.

The Risk of Over-Optimistic Planning

If you are planning for a major goal like retirement or your child's education, using an inflated return assumption can be a significant risk. If you calculate your investment needs based on a 20% return and the actual result is 14%, you will face a large shortfall at the end of your investment horizon. Often, this shortfall is discovered late in the journey, leaving very little time to make changes or invest more money to bridge the gap. Financial planners generally suggest being conservative—assuming a return of 12-14%—to ensure you reach your target even if market conditions are not always favorable.

How Investors May Read This

Instead of chasing funds that had the highest returns in the last three years, investors may benefit from looking at a broader set of data. This includes checking rolling returns, which show how a fund has performed over different time periods, not just the most recent ones. It is also important to assess risk-adjusted returns—how much risk the fund manager took to earn that profit—and the consistency of the investment strategy. A fund that provides steady, reliable performance across different market cycles is often a more useful tool for long-term wealth creation than one that produces explosive gains followed by periods of sharp decline.

What Investors Should Track

Investors may focus on consistent performance over longer periods rather than chasing the latest top-performing funds. Key monitorables include the fund manager’s track record, the fund’s expense ratio, and how the portfolio behaves during market corrections. Reviewing your financial goals annually and adjusting for realistic return expectations can help ensure that you remain on track, regardless of market volatility.
