$NPV= -A+\sum_{t=0}^{T} \frac{EZU}{(1+EZF)^t} $

Hey guys.

can someone please adjust this equation in a way where I have all the values Except for (EZF). In a way replacing NPV and EZF

1 Answer

Using the formula for geometric series ( we get 
$$NPV= -A+\sum_{t=0}^{T} \frac{EZU}{(1+EZF)^t}=-A+EZU(\frac{1-(1+EZF)^{T+1}}{1-(1+EZF)}) $$
This equation can not be explicitly solved in terms of $EZF$ and one needs to solve it numerically.

    sorry, I think there has been a confusion. EZF and EZU are two different values, you can simply replace them with X and Y

      I revised my solution.
