The figuring out an identical cash float is the risk-free cash float that an investor or manager considers an identical to any other expected cash float which is higher, however moreover riskier. The components for calculating the data an identical cash float is as follows:


Stroll within the park An an identical Cash Go with the flow = Expected Cash Go with the flow ( 1   +   Risk Best elegance )

text{Stroll within the park An an identical Cash Go with the flow} = frac{text{Expected Cash Go with the flow}}{left(1 + text{Risk Best elegance} correct )} Stroll within the park An an identical Cash Go with the flow=(1 + Risk Best elegance)Expected Cash Go with the flow​

The danger best price is calculated for the reason that risk-adjusted rate of return minus the risk-free rate. The expected cash float is calculated by the use of taking the probability-weighted dollar value of every expected cash float and together with them up.

For example, consider that an investor has the choice to simply settle for a confident $10 million cash inflow or an risk with the following expectations:

  • A 30% likelihood of receiving $7.5 million
  • A 50% likelihood of receiving $15.5 million
  • A 20% likelihood of receiving $4 million

According to the ones probabilities, the expected cash float of this scenario is:


Expected Cash Go with the flow = 0 . 3 × $ 7 . 5  Million + 0 . 5 × $ 1 5 . 5  Million + 0 . 2 × $ 4  Million

get started{aligned} text{Expected Cash Go with the flow} &= 0.3times$7.5text{ Million}&quad + 0.5times $15.5text{ Million}&quad + 0.2times$4text{ Million} &=$10.8 text{ Million} end{aligned} Expected Cash Go with the flow​=0.3×$7.5 Million+0.5×$15.5 Million+0.2×$4 Million​

Suppose the risk-adjusted rate of return used to cut price this option is 12% and the risk-free rate is 3%. Thus, the risk best price is (12% – 3%), or 9%. Using the above equation, the data an identical cash float is:


Stroll within the park An an identical Cash Go with the flow = $ 1 0 . 8  Million ( 1 + 0 . 0 9 )

get started{aligned} text{Stroll within the park An an identical Cash Go with the flow} &= frac{$10.8 text{ Million}}{left(1 + 0.09 correct )} &=$9.908 text{ Million} end{aligned} Stroll within the park An an identical Cash Go with the flow​=(1+0.09)$10.8 Million​​

According to this, if the investor prefers to keep away from risk, he must accept any confident risk worth more than $9.908 million.
