However what precisely is the time-weighted fee of return, how do you calculate it, and why is it thought-about the gold commonplace when measuring a portfolio’s efficiency? 


What Is Time-Weighted Charge of Return (TWR | TWRR)?

The time-weighted return of an funding is a comparatively easy calculation to indicate buyers what share returns their portfolio has skilled over a predetermined time period. The truth that it ignores money flows is what makes the speed of return such a compelling indicator of a portfolio’s efficiency. 

Money inflows and outflows — cash you add or subtract out of your account — will result in modifications in your general portfolio’s steadiness that can artificially inflate or deflate your portfolio’s share progress over time. For instance, for those who have been to make a withdrawal, grabbing 25% of your portfolio’s worth to purchase a automobile, your portfolio steadiness would drop by 25%. At first look, the drastic decline in your general portfolio’s worth would make it appear to be your investments are doing horribly available in the market for those who seemed solely on the historical past of your portfolio steadiness. 

The time-weighted fee of return is a calculation that will fully ignore the truth that 25% of the portfolio’s worth was taken out of the portfolio. As a substitute you possibly can see how the cash you do have invested has carried out over time. Right here’s the way it works:


3 Steps to Calculate the Time-Weighted Return

There are three broad steps to calculating the TWR of an funding portfolio:

Step #1: Divide the Total Time Into Sub-Durations

To ensure that the calculation to weed out the noise of money inflows and outflows, you’ll have to divide the general time period into sub-periods based mostly on when these deposits and withdrawals passed off. 

Each time you set cash into or take cash out of your portfolio, you’re ending the earlier sub-period and beginning a brand new one. If you happen to haven’t made any contributions or taken any cash out over the time period you’re trying into, there’ll solely be one sub-period. 

Step #2: Calculate Sub-Interval Charges of Return (RoR)

Now, it’s time to calculate every sub-period return. To take action, divide the ending steadiness on the finish of the sub-period by the start steadiness, and subtract 1. Right here’s the equation:

Sub-Interval Return = (Ending Worth / Beginning Worth) – 1

Do that for every sub-period you may have in your general time interval, leading to a fee of return for every interval. 

Step #3: Discover the Geometric Imply

To seek out the geometric imply, you’ll add one to every interval return, multiply them collectively, and subtract 1. The ensuing share is the proportion achieve or loss the portfolio has skilled on a time-weighted foundation — your time-weighted fee of return.  


TWR Instance Calculation

The steps above could look like fairly a bit to comply with, so let’s break it down with a sensible instance. For simplicity’s sake, let’s say John Doe invested 100% of his portfolio within the S&P 500, that means we will use real-world knowledge from the S&P 500 to kind the instance. To maintain the calculations easy, we’ll assume Doe contributed the precise worth of the S&P 500 every time he added funds, however you’ll use no matter greenback quantity you contribute or withdraw to run these numbers your self.

Mr. Doe needs to know his TWRR from January 28, 2021, to January 28, 2022. On January 28, 2021, he began with an preliminary funding of $3,787.38. When shares dipped in early March, he determined so as to add one other $3,768.47 to his portfolio on March 4. He then added one other $4,513.04 to his portfolio on December 1 when he obtained an end-of-the-year vacation bonus. 

Right here’s how Mr. Doe would do the return calculation:

Step #1: Discover the Sub-Durations

The preliminary funding was made on January 28, 2021, with the following funding on March 4. Due to this fact, sub-period one ranges from January 28, 2021 by way of March 4, 2021. 

He made his subsequent contribution on December 1, 2021, that means March 4, 2021 to December 1, 2021 is the second interval. 

Lastly, December 1, 2021 to January 28, 2022 represents the third interval. 

Step #2: Calculate Interval Returns

Throughout the first interval, John Doe’s portfolio fell from a price of $3,787.38 to a price of $3,768.47. Dividing $3,768.47 by $3,787.38 and subtracting 1 reveals the speed of return on this interval got here to -0.005, or -0.5%. 

Then Doe added a contribution, so in interval 2 the beginning steadiness was $7,536.94. The ending steadiness was $9,026.08. While you divide $9,026.08 by $7,536.94 and subtract 1, you come to 0.1976, or a 19.76% return for the interval. 

Lastly, Doe made his final contribution. Interval 3 had a beginning steadiness of $13,539.12 and an ending steadiness of $13,109.61. Dividing the ending steadiness by the beginning steadiness and subtracting 1 reveals a lack of 0.0317, or -3.17% for this sub-period. 

So, the general returns for all three intervals have been:

  1. Interval 1: -0.005 (-0.5%)
  2. Interval 2: 0.1976 (+19.76%)
  3. Interval 3: -0.0317 (-3.17%)

Step #3: Discover the TWR Utilizing the Geometric Imply. 

Begin by including 1 to all of the values above, bringing you to the values of:

  1. Interval 1. 0.995
  2. Interval 2. 1.1976
  3. Interval 3. 0.9683

Now, John multiplies these three values collectively and will get 1.1538. 

Now, by subtracting 1, Mr. Doe will discover that his portfolio efficiency on a TWR foundation was 0.1538 (15.38%) for the interval starting from January 28, 2021 to January 28, 2022.


What Time-Weighted Return Measures

Because the title of the metric suggests, time-weighted returns measure portfolio returns over a time period. Nonetheless, trying on the instance above, you’ll discover one thing attention-grabbing for those who dig deep sufficient. 

Throughout the interval from January 28, 2021 to January 28, 2022, the general return of the S&P 500 additionally got here in at 15.38%. The instance was written with the S&P 500 because the underlying asset to make precisely this level. 

Though Doe made three complete contributions to his portfolio, the returns of his portfolio have been precisely that of the underlying belongings, no extra, no much less, whatever the contributions he added and when. 

With the calculation’s skill to weed out money flows, it offers a full view of precisely what buyers are incomes on their investments. 


TWR vs. Different Charges of Return

Figuring out the return of your funding portfolio is usually a tough process, largely as a result of there are such a lot of calculations you should use that every come to a special outcome. The hot button is choosing the proper fee of return to make use of for the scenario at hand. 

Cash-Weighted Charge of Return (MWR)

One other generally used calculation is named the money-weighted, or dollar-weighted, return. This return fee focuses on each the returns of the underlying belongings held by the portfolio and money flows out and in of the portfolio. 

Utilizing the instance of John Doe’s portfolio above, on January 28, 2021, he began with an preliminary funding of $3,787.38 and had an ending steadiness on January 28, 2022 of $13,109.61. 

Calculating the MWR is finest carried out in a spreadsheet like Microsoft Excel or Google Sheets by plotting the beginning date, adopted by the date of every contribution, and the top date in column A. In column B, plot all contributions as positives and the ending steadiness as a detrimental (as if you have been withdrawing the steadiness on the finish). 

Then, use the inner fee of return (XIRR) perform in your spreadsheet to seek out the MWR for the column of values. While you’re carried out, your chart ought to appear to be this (based mostly on the John Doe instance above). 

A B
January 28, 2021 $3,787.38
March 4, 2021 $3,768.47
December 1, 2021 $4,513.04
January 28, 2022 -$13,109.61
MWR 13.25%

Primarily based on the info we have now, John Doe’s MWR involves 13.25%, a reasonably far cry from the TWR of 15.38%. 

So, what makes the distinction?

The cash-weighted return tracks the contributions and deductions made in a portfolio, and the timing of those strikes. Since John Doe’s greatest contribution was made proper earlier than a market correction led to important declines, and the market hadn’t recovered by the top of the general time interval, his MWR was affected fairly considerably. 

Listed below are the methods during which MWR and TWR differ:

Metric TWR MWR
Accounts for Market Exercise Sure Sure
Accounts for Money Flows No Sure
What it Determines The speed at which belongings within the portfolio are rising on common.  Whether or not your contributions, together with market exercise, will probably be sufficient to fulfill your monetary objectives.

The Dietz mannequin was created by Peter Dietz in 1960 as a approach to calculate your money-weighted return fee in a much less computer-intensive manner. As we speak, computer systems are much more highly effective than something in 1960, and the necessity for much less intensive computing doesn’t exist anymore. 

As we speak, the Dietz mannequin offers a neater methodology for calculating your true money-weighted return. Nonetheless, it’s vital to say that the modified Dietz mannequin doesn’t all the time present an correct depiction of your MWR. 

This return mannequin requires the portfolio worth on the beginning date and finish date, however not like the standard TWRR, you received’t have to know your portfolio’s general worth on the date of every money circulate. You’ll need to know the date and quantity of every money circulate occasion, and whether or not it’s an influx or outflow. The Company Finance Institute presents an in-depth have a look at the Modified Dietz Mannequin and the system for those who’re all for studying the way it works. 

Listed below are the important thing variations between the TWR and the Dietz Mannequin:
