When it comes to selecting mutual funds for investment, there are various criteria available to evaluate them. Among many, two key parameters are good fund ratings and low expense ratios. So in this write-up, we will review three 5-star rated, lowest expense ratio small-cap mutual funds that have grown a Rs 1 lakh investment into more than Rs 5 lakh in the last five years. These funds have given up to 40% returns over the past five years. These schemes have also delivered exceptional returns over both 1-year and 3-year periods. Before we dive into the details of these three small-cap mutual funds, it’s important to understand the significance of fund ratings and expense ratios in mutual fund investing.
How is fund rating so important in MF investing?
Ratings can help you compare different mutual fund schemes within a category and select funds with better risk-adjusted returns. Ratings also help in understanding the potential stability of your investments. Ratings, by Value Research or CRISIL, are a tool that helps in assessing the past performance and risk of a fund. Looking at fund ratings, investors can make informed decisions about their investment.

What is expense ratio and how is it important?
The expense ratio is the annual operating expenses of a mutual fund scheme, shown as a percentage of the fund’s net assets. Essentially, it’s the percentage of your investment that the fund charges each year to cover its administrative and management costs, according to the Association of Mutual Funds in India (AMFI). So if your fund’s expense ratio is higher, it means you are paying higher fee to the fund house to manage your investment, potentially impacting your overall returns.
Now that we have discussed how crucial fund ratings and expense ratios are as key parameters while identifying a fund for investing. Now, let’s explore the small-cap mutual funds with 5-star ratings by Value Research and the lowest expense ratio. We have shortlisted three mutual fund schemes based on these two criteria. Let’s review their five-year lump sum and SIP performance primarily, along with one- and three-year returns.

Investors are advised not to rely solely on the impressive returns delivered by these small-cap funds over the past five years and review the schemes based on several other yardsticks. Past performance does not guarantee similar results in the future.
It’s also important for investors to keep in mind that the five-year returns may appear attractive because many funds rebounded from a low base after the equity market crash in 2020 during the COVID-19 pandemic.
Also, while investing in small-cap funds, investors must remember that investing in small-cap funds can be riskier as compared to midcap, large-cap or multi-cap funds. Since small-cap companies are subject to high volatility and market fluctuations during economic downturns and unforeseen events, you should carefully decide your portfolio balance and allocate funds in small-cap mutual funds wisely.
