Fund Turnover and Its Impact on Costs

What is Fund Turnover?

Fund turnover, also called the portfolio turnover ratio, measures the proportion of a fund’s holdings bought and sold over a twelve-month period. A higher percentage indicates more active trading, while a lower percentage reflects a relatively stable buy-and-hold approach.

Under disclosure rules issued by the Securities and Exchange Board of India (SEBI), funds must report this ratio in scheme documents and annual reports. The calculation uses the lower of total purchases or total sales during the year. This figure is divided by the fund’s average net assets and multiplied by 100 to express it as a percentage.

For instance, if securities valued at ₹10 crore were traded and the average assets stood at ₹40 crore, the turnover comes to 25%.

How Fund Turnover is Calculated?

Understanding the method helps interpret the number correctly.

Key components used in calculation:

• The total value of securities purchased during the year
• The total value of securities sold during the same year
• The average net assets over the twelve-month period

Rules require using the lower of purchases or sales to stop trading activity from being overstated. The figure is divided by average assets and multiplied by 100. This ratio is reported in annual financial statements and scheme information documents. Investors comparing mutual funds often review them alongside the expense ratio.

Why Fund Turnover Matters?

The fund turnover ratio offers insight into how a scheme is managed.

• Cost implications: Increased trading activity generally leads to higher brokerage and transaction costs. These costs form part of the complete cost faced by investors. Although restricted under SEBI’s total expense ratio limits, they still influence net returns.
• Tax considerations: Selling frequently can give rise to short-term capital gains in a portfolio. In India, short-term capital gains on equity schemes carry a 20% tax, along with applicable surcharge and cess under the regulations in 2026. Long-term capital gains exceeding ₹1.25 lakh in a financial year are taxed at 12.5%, without indexation. Higher turnover may therefore affect tax efficiency.
• Investment style indication: Actively managed equity schemes often show higher ratios. Index funds generally display lower turnover because they replicate a benchmark. A sudden change in the ratio may signal a shift in investment strategy.

What is Considered a Good Fund Turnover?

There is no universal ideal percentage. The appropriate level depends on the fund category and mandate. Index schemes typically record turnover in the range of 20–30% or lower. Actively managed equity schemes may exceed 50% in certain years. Debt schemes vary depending on maturity strategy.

A very high figure does not automatically indicate better performance. Similarly, a low ratio does not guarantee stability or returns. It should be assessed together with portfolio composition and investment objectives.

Investors analysing mutual funds typically compare turnover across similar categories. Reviewing holdings also helps identify concentration risks. Fund turnover is therefore a transparency measure. It reflects trading frequency, cost sensitivity, and management approach. When assessed alongside the expense ratio, asset allocation, and risk details, it provides a balanced context.

Key Takeaways

Fund turnover describes how often a fund carries out buying and selling in a year. It is expressed as a percentage of the portfolio replaced annually. The ratio is worked out using the lower of total purchases or sales divided by average net assets. High turnover generally shows active management and higher transaction costs. Lower turnover usually reflects a steady long-term investment approach.
