Hoskold method for annual rate of return prediction-1

Input(s)

C: Initial Investment/Capital ($)

$r_{H}$ : Speculative Ratio (fraction)

$i$ : Rate of Interest (per cent)

$n$ : Life of the Project (years)

D: Present worth Factor (dimensionless)

$D E$ : Present worth Factor with Total Net Undiscounted Cash Flow during the whole project ($)

$r_{H}$ : Speculative Ratio (fraction)

\begin{gathered} D E=r_{H} \cdot C \frac{1-\left(\frac{1}{1+i}\right)^{n}}{i}+\left(\frac{1}{1+i}\right)^{n} \cdot C \\ r_{H}=i \cdot \frac{\frac{D E}{C}-(1+i)^{-n}}{1-(1+i)^{-n}} \end{gathered}

Control Form:

\mathrm{C} \leq \frac{\mathrm{DE}}{\frac{\mathrm{r}_{\mathrm{H}}}{\mathrm{i}}-\left[\left(\frac{\mathrm{r}_{\mathrm{H}}}{\mathrm{i}}-1\right) \cdot(1+\mathrm{i})^{-\mathrm{n}}\right]}
