Final answer:
In Excel, cell B9's NPV formula would be =NPV(B2, B11:B14), reflecting the interest rate in B2 and the variable payments in B11:B14. As interest rates rise, the present value of future payments falls since they are discounted more heavily, potentially lowering the value of an investment like a bond.
Step-by-step explanation:
In order to calculate the present value of a payment plan with variable annual payments in cell B9 using the NPV function in Excel, you would write the formula =NPV(B2, B11:B14). Here, B2 contains the interest rate, which is used as the discount rate for the NPV calculation, and B11:B14 contains the list of variable annual payments. This formula takes into account the interest rate being stored in cell B2 to discount the future payments to their present value.
It is important to note that when the interest rate rises, the present value of future payments will decrease. This is because future cash flows are discounted at a higher rate, reflecting the increased opportunity cost of the funds, or the increased rate at which the funds could have been invested. As such, if an investor wishes to sell an investment like a bond when interest rates have risen, they may find that the value of these future payments—and therefore the investment itself—has fallen.
Moreover, the final present value is the sum of all individual present values calculated for each payment period. The calculation is made based on the provided interest rates, and the fact that the received future dollar payments do not change.
