How to Choose the Right Debt Fund?

Now that you know how a debt fund works and its types, it’s important to pick the right debt fund that matches your needs. Before you invest in a debt fund, consider these parameters:

Match Fund Duration with Investment Horizon

One of the most significant factors when choosing from different types of debt funds is maturity profile of the scheme. The best debt mutual funds for long term are the ones invested in PSUs and Government securities such as Gilt Fund with 10-year constant duration. There are also short-term debt funds varying from overnight to few months if you have any specific financial goals.

Risk Appetite

Although debt funds mostly invest in fixed income securities, they carry risk that can be affected by factors such as market trends, investment strategy and nature of the securities. If you have high risk appetite, consider investing in longer duration debt funds. And for low to moderate risk-taking investments, consider short term debt fund investments.

Understand Credit Risk

Credit risk is the chance that the issuer might fail to pay back the interest or the principal amount on time. Debt instruments are rated by credit rating agencies based on this risk level. Check the rating for a debt fund to know it’s quality.

Examine Past Performance

The past performance of debt fund can provide evidence for how the fund is managed and what returns it could provide in the future. Although not the most reliable indicator for future returns, it can show whether the fund has been able to provide consistent returns through market fluctuations or not.

Check Expense Ratio and Fund Manager Reputation

The expense ratio reflects the yearly cost you incur for managing the fund. A lower ratio helps retain more of your returns. Also, consider the track record of the fund manager, as their decisions significantly influence fund performance.

Average Maturity and Yield to Maturity (YTM)

Check the fund’s average maturity to see how long it will take on average, for its investments to mature. YTM (Yield to Maturity) gives an estimate of the return you could earn if you hold the fund till maturity, assuming no defaults.
