The variables in a present value of an annuity problem include all of the following, except:
A
Interest rate per period ($i$)
B
Periodic payment amount ($PMT$)
C
Number of periods ($n$)
D
Future value of a single sum ($FV$)
Verified step by step guidance
1
Understand the concept of the present value of an annuity. It is the current worth of a series of equal payments made at regular intervals, discounted at a specific interest rate.
Identify the key variables involved in the calculation of the present value of an annuity. These include: the interest rate per period ($i$), the periodic payment amount ($PMT$), and the number of periods ($n$).
Recognize that the future value of a single sum ($FV$) is not relevant to the calculation of the present value of an annuity. The future value pertains to a single lump sum, not a series of payments.
Review the formula for the present value of an annuity: \( PV = PMT \times \frac{1 - (1 + i)^{-n}}{i} \). Note that $FV$ does not appear in this formula.
Conclude that the correct answer is 'Future value of a single sum ($FV$)' because it is not a variable used in the present value of an annuity calculation.
