Ақшамен өлшенген қайтарым мөлшері
Ақшамен өлшенген кірістілік деңгейі қандай?
Ақшамен өлшенген кірістілік коэффициенті (MWRR) инвестицияның нәтижелілігін анықтайды. MWRR барлық ақша ағындарының дисконтталған мәндерін бастапқы инвестиция құнына теңестіретін кірістілік мөлшерлемесін табу арқылы есептеледі. MWRR ішкі кірістілік деңгейіне (IRR) тең.

How to Calculate the Money-Weighted Rate of Return
- To calculate IRR using the formula, set net present value equal to zero and solve for the discount rate (r), which is the IRR.
- However, because of the nature of the formula, IRR cannot be calculated analytically and must instead be calculated either through trial and error or using software programmed to calculate IRR.
What Does the Money-Weighted Rate of Return Tell You?
There are many ways to measure asset returns, and it is important to know which method is being used when reviewing asset performance. The MWRR incorporates the size and timing of cash flows, so it is an effective measure of portfolio returns.
The MWRR sets the initial value of an investment to equal the future cash flows, such as dividends added, withdrawals, deposits, and sale proceeds. In other words, the MWRR helps determine the rate of return needed to start with the initial investment amount factoring all of the changes to cash flows during the investment period including the sale proceeds.
Cash Flows and the Money-Weighted Rate of Return
As stated earlier, the MWRR for an investment is identical in concept to the IRR. In other words, it is the discount rate on which the net present value (NPV) = 0, or the present value of inflows = present value of outflows.
It’s important to identify the cash flows in and out of a portfolio including the sale of the asset or investment. Some of the cash flows that an investor might have in a portfolio include:
Outflows
- The cost of any investment purchased
- Reinvested dividends or interest
- Withdrawals
Inflows
- The proceeds from any investment sold
- Dividends or interest received
- Contributions
Example of the Money-Weighted Rate of Return
Each inflow or outflow must be discounted back to the present using a rate (r) that will make PV (inflows) = PV (outflows).
Let’s say an investor buys one share of a stock for $50 that pays an annual $2 dividend and sells it after two years for $65. The MWRR will be a rate that satisfies the following equation:
PV Outflows=PV Inflows=$21+r+$21+r2+$651+r2=$50\begin{aligned} PV \text{ Outflows} &= PV \text{ Inflows} \\ &= \frac{ \$2 }{ 1 + r } + \frac{ \$2 }{ 1 + r^2 } + \frac{ \$65 }{ 1 + r^2} \\ &= \$50 \end{aligned}PV Outflows=PV Inflows=1+r
Solving for r using a spreadsheet or financial calculator, we have an MWRR of 11.73%.
The Difference Between Money-Weighted Rate of Return and Time-Weighted Rate of Return
The money-weighted rate of return is often compared to the time-weighted rate of return (TWRR), but the two calculations have distinct differences. The TWRR is a measure of the compound rate of growth in a portfolio. The TWRR measure is often used to compare the returns of investment managers because it eliminates the distorting effects on growth rates created by inflows and outflows of money.
It can be difficult to determine how much money was earned on a portfolio because deposits and withdrawals distort the value of the return on the portfolio. Investors can’t simply subtract the beginning balance, after the initial deposit, from the ending balance since the ending balance reflects both the rate of return on the investments and any deposits or withdrawals during the time invested in the fund.
The TWRR breaks up the return on an investment portfolio into separate intervals based on whether money was added or withdrawn from the fund. The MWRR differs in that it takes into account investor behavior via the impact of fund inflows and outflows on performance but doesn’t separate the intervals where cash flows occurred like the TWRR. Therefore, cash outlays or inflows can impact the MWRR. If there are no cash flows, then both methods should deliver the same or similar results.
Limitations of Using Money-Weighted Rate of Return
The MWRR considers all the cash flows from the fund or contribution, including withdrawals. Should an investment extend over several quarters, for example, the MWRR lends more weight to the performance of the fund when it is at its largest. Hence, the description «money-weighted.»
The weighting can penalize fund managers because of cash flows over which they have no control. In other words, if an investor adds a large sum of money to a portfolio just before its performance rises, it equates to positive action. This is because the larger portfolio benefits more (in dollar terms) from the growth of the portfolio than if the contribution had not been made.
On the other hand, if an investor withdraws funds from a portfolio just prior to a surge in performance, it equates to a negative action. The now-smaller fund sees less benefit (in dollar terms) from the growth of the portfolio than if the withdrawal had not occurred.
