Payout Period Plus Interest

Payout Period Plus Interest Payout period (POP) is the time that will be required to recover the depreciable fixed capital investment from the accrued after-tax cash flow of a project with no interest considerations. In equation format 

This model does not take into account the time value of money, and no consideration is given to cash flows that occur in a project s later years after the depreciable investment has been recovered. A variation on this method includes interest, called payout period plus interest (POP + I) and the net effect is to increase the payout period. This variation accounts for the time value of money. 

Net Present Worth In the net present worth method, an arbitrary time frame is selected as the basis of calculation. This method is the measure many companies use, as it reflects properly the time value of money and its effect on profitability. In equation form 

When the NPW is calculated according to Eq. (9-21), if the result is positive, the venture will earn more than the interest (discount) rate used conversely, if the NPW is negative, the venture earns less than that rate.
