Which factor is NOT needed to calculate present value of uneven cash flows?

To calculate the present value of uneven cash flows, you generally need to know the future cash flows expected at different time periods, the discount rate to account for the time value of money, and importantly, the number of time periods over which these cash flows will occur.

The sale price and the initial investment amount are not necessary components for calculating the present value of future cash flows. In this context, the sale price refers to the amount at which an asset is sold, which does not directly affect the present value calculation of the cash flows generated from its use. The initial investment amount may provide context for the overall investment analysis (like determining the net present value), but it is not directly involved in calculating the present value of the cash flows alone.

In contrast, to determine the present value itself, you apply the cash flows to the discount rate over the respective time periods; hence, both the discount rate and the number of time periods are essential elements in this calculation. Thus, the initial investment amount is the factor that is not strictly needed when calculating present value for uneven cash flows.
