Trailing returns and Rolling returns:Meaning, Key Differences and How to Caluculate?

Trailing and rolling returns are two common ways to measure mutual fund performance. While trailing returns show returns between two fixed dates, rolling returns help investors understand how consistently a fund performed across different market cycles.

Key Highlights:

• Trailing returns reflect historical performance over a specific investment period.
• Rolling returns measure return consistency across multiple overlapping periods.
• Using both metrics provides a more complete picture of a mutual fund's past performance.

What are Trailing returns?

Trailing returns are the returns generated over a given period. It can be the year to date (YTD), one year, three years, and so on. These are also called point to point returns. Trailing returns are the most relevant measures to evaluate the performance for a mutual fund.

Features of Trailing returns

Most relevant Used by mutual funds to publish performance over different time blocks:

• Measures returns over a fixed period such as 1 year, 3 years, 5 years, or since inception.
• Uses a single start and end date to calculate point-to-point performance.
• Easy to understand and compare across different mutual funds.
• Widely published by mutual fund houses in factsheets and performance reports.
• Can be influenced by market conditions at the chosen start and end dates, so it may not reflect long-term consistency.

Examples of Trailing returns

The following example shows trailing returns of ELSS mutual funds across different fixed investment periods such as 3 months, 1 year, 3 years, and 5 years:

Rolling returns

Rolling returns measure a mutual fund’s performance across multiple time periods instead of just one fixed period. This helps investors understand how consistently the fund has performed during different market conditions.

Advantages of Rolling Returns

• Shows consistency
• Reduces period bias
• Better for SIP investors
• Helps compare long-term performance

Examples of Rolling returns in Mutual Funds

The following example shows rolling returns of mutual funds across multiple time periods to measure return consistency over different market conditions:

The trailing return will show the way a fund has performed in the long run. Yet, it’s difficult to understand from this data as to how consistent the fund was during good and bad times which affects the return per cent to an investor.

Difference Between Trailing Returns and Rolling Returns

Both trailing and rolling returns measure mutual fund performance, but they differ in how they calculate returns and the insights they provide to investors. 

Calculation For Trailing and Rolling Return

Trailing Return measures the return earned over a fixed investment period ending on a specific date whereas Rolling Return measures the average return across multiple overlapping periods to assess performance consistency. 

Both trailing and rolling returns measure past performance, but their calculation methods provide different insights into investment returns. Lets understand the calculation in detail.

Trailing Return

Assume an investment of ₹1,00,000 in a mutual fund on 1 June 2023, where its value has grown to ₹1,40,000 on 1 June 2026.

Let’s calculate the trailing return using the formula:

Trailing Return (CAGR) = [(Ending Value ÷ Beginning Value) ^ (1 ÷ n)] − 1 

• CAGR = [(1,40,000/1,00,000) ^(⅓)]-1
• CAGR = 11.87%

This means the fund generated an average annual return of around 11.87% over the last 3 years.

Rolling Return 

Assume you want to calculate the 3-year rolling return of a mutual fund over different periods.

• ₹1,00,000 invested on 1 June 2020 grew to ₹1,45,000 on 1 June 2023.
• ₹1,00,000 invested on 1 July 2020 grew to ₹1,42,000 on 1 July 2023.
• ₹1,00,000 invested on 1 August 2020 grew to ₹1,48,000 on 1 August 2023.

Let’s calculate the rolling return using the CAGR formula for each period:

Rolling Return (CAGR) = [(Ending Value ÷ Beginning Value) ^ (1 ÷ n)] − 1

For 1 June 2020 – 1 June 2023: CAGR = [(1,45,000 ÷ 1,00,000) ^ (⅓)] − 1
CAGR = 13.22%

For 1 July 2020 – 1 July 2023: CAGR = [(1,42,000 ÷ 1,00,000) ^ (⅓)] − 1
CAGR = 12.42%

For 1 August 2020 – 1 August 2023: CAGR = [(1,48,000 ÷ 1,00,000) ^ (⅓)] − 1
CAGR = 13.91%

The average of these rolling returns shows how consistently the fund performed across multiple 3-year periods, rather than relying on a single start and end date.

Trailing vs Rolling Returns which is Better?

Trailing returns are useful for quickly checking a mutual fund’s past performance over a specific period, while rolling returns provide a more consistent view by analysing performance across different market cycles.

For most investors, especially long-term and SIP investors, using both together gives a more balanced and reliable understanding of a fund’s performance.

Conclusion

Trailing returns help investors understand how a mutual fund performed over a fixed period, while rolling returns show how consistently the fund delivered returns across different market conditions. For long-term and SIP investors, rolling returns are often considered a more reliable way to evaluate mutual fund performance.
