When you\u2019re tracking investment performance, cash deposits<\/a><\/strong> and withdrawals can skew your returns, making it hard to judge how well your portfolio is really doing.\u00a0That\u2019s where the <\/span>Time-Weighted Rate of Return <\/b>(TWRR) comes in.\u00a0TWRR isolates your portfolio\u2019s performance by removing the impact of cash inflows and outflows.\u00a0This gives a better picture of how your investments or fund manager are truly performing.<\/span><\/p>\n

In this article, we\u2019ll break down how TWRR works and show you exactly how to calculate it with the help of real-world examples.<\/span><\/p>\n

<\/span>What Is the Time-Weighted Rate of Return?<\/b><\/span><\/h2>\n

Time-weighted rate of return<\/b> is a calculation method used for measuring the compound growth rate of an investment portfolio over time. In other words, (TWR) provides the compound growth rate of each fund after eliminating the effects of deposits and withdrawals. It splits the portfolio’s return into sub-periods based on the investments and redemptions made throughout the investment.<\/span><\/p>\n

Moreover, this financial metric removes the twisted effects of growth rates created by external cash flows, providing a more accurate measure of portfolio performance. The <\/span>time-weighted rate of return<\/b> is also known as the geometric mean, as it multiplies all the sub-periods to generate the rate for the whole period.\u00a0<\/span><\/p>\n

Remember, there is a difference between time-weighted return and annual rate of return, which is the percentage of profit and loss generated from an investment over a certain period.<\/span><\/p>\n

<\/span>Importance of TWR<\/b><\/span><\/h2>\n

In any investment portfolio, frequent deposits and withdrawals can make it difficult to accurately calculate the overall rate of return. Due to these cash flows, simply comparing the starting and ending balances doesn\u2019t provide a clear picture, as the ending balance reflects both investment performance and the effects of cash inflows and outflows.<\/span><\/p>\n

This is where the <\/span>time-weighted rate of return<\/b> (TWRR) proves useful. TWRR calculates the return for each period between cash flow events, effectively isolating the portfolio’s actual performance. By breaking down the total return into individual time segments, TWRR provides a more accurate and consistent measure of investment performance.<\/span><\/p>\n

<\/span>Formula for Calculating TWR<\/b><\/span><\/h2>\n

Calculation of the <\/span>time-weighted rate of return<\/b> formula for a certain period is done as below-<\/span><\/p>\n

Time-weighted return formula = (Ending value – beginning value) \/ beginning value<\/b><\/p>\n

For example –\u00a0<\/span><\/p>\n

Vivek invested \u20b960,000 in a <\/span>mutual fund<\/span><\/a> on 1 January 2019. On 31 December 2019, his portfolio stood at \u20b961,000.<\/span><\/p>\n

Let\u2019s put these numbers into the formula-<\/span><\/p>\n

TWR = (61,000 – 60,000) \/ 60,000<\/span><\/p>\n

Therefore, TWR = 0.0167 = 1.6%<\/span><\/p>\n

The TWR formula is useful for calculating each sub-period when new investments or redemptions are made.\u00a0<\/span><\/p>\n

Thus, the <\/span>time-weighted rate of return<\/b> formula is useful when multiple sub-periods are involved and is given below –\u00a0<\/span><\/p>\n

Time-weighted return formula = [(1 + rate of return from the 1st period) x (1 + rate of return from the 2nd period) x\u2026x (1 + rate of return from the nth period)] – 1<\/b><\/p>\n

Let\u2019s understand the above formula with the help of an example –\u00a0<\/span><\/p>\n

Vivek, after receiving \u20b961,000 on 31 December 2019, invested a further amount of \u20b930,000 on 1 January 2020. On 31 December 2020, his portfolio was valued at \u20b995,000. But he later withdrew \u20b920,000 from his investment on 1 January 2021. Now, on 31 December 2021, his portfolio valuation will be \u20b977,000.\u00a0<\/span><\/p>\n

The <\/span>time-weighted rate of return<\/b> calculation for each of the three sub-periods is given below-<\/span><\/p>\n
