# What is TWR – Time-Weighted Rate of Return? TWR – The time-weighted rate of return is the compound`s measure rate of growth in a portfolio. The TWR measures are used to compare the investment managers` returns because it removes the effects on growth rates. Inflows and outflows of money create these rates. The time-weighted return can break up the return on a portfolio of investment into separate intervals. It shows if money was going into or out of the fund.

## How to Calculate Time-Weighted Rate of Return?

1. Calculate the return rate for each sub-period. First, you should subtract the beginning balance of the period from the ending balance and divide the result by the beginning balance.
2. You can create a new sub-period for each period. There is a change in cash flow, whether it’s a deposit or withdrawal. You have to add one to each rate of return, which makes negative returns easier to calculate.
3. You can multiply each sub-period of the rate of return by each other. In order to achieve the TWR, Subtract the result by one.

## What Does TWR mean to You?

It can be challenging to determine how much money was earned on a portfolio when multiple deposits and withdrawals were made over time. After the initial deposit, it is not simple for Investors to subtract the beginning balance from the ending balance. The ending balance reflects withdrawals during the time invested in the fund or the rate of return on the investments and any deposits. In other words, withdrawals and deposits distort the value of the return on the portfolio.

The time-weighted return can break up an investment portfolio into separate intervals. It is based on whether someone added the money or withdrawn it from the fund. The TWR provides for each sub-period the return rate or interval that had changes in cash flow. By isolating the returns with cash flow changes, the result can be more accurate than taking the beginning balance and ending balance in a fund. The time-weighted return can multiply the returns for the holding period or each sub-period, which links them together, showing compounded returns over time.

All cash distributions are reinvested in the portfolio when calculating the time-weighted rate of return. Whenever there is external cash flow, there is also a need for Daily portfolio valuations. These periods determine the time-weighted rate of return.

Investment managers who deal in publicly traded securities do not have control over fund investors’ cash flows. The time-weighted rate of return is considered a popular performance measure for funds.

## Difference Between ROR and TWR

ROR – a return rate of the gain or loss on an investment over a specified period, shows a percentage of the initial cost of the investment. Gains on investments are received income plus any capital gains realized on the sale of the asset.

However, the return calculation rate does not account for the cash flow differences in the portfolio. In contrast, the TWR accounts for all deposits and withdrawals in determining the rate of return.

## Limitations of the Time-Weighted Rate

Because the cash flow changes in and out of funds daily, the TWR can calculate and keep track of the cash flows. It would be best to use computational software or an online calculator. The money-weighted rate of return is another often used rate of return calculation.
