a) Consider a $762 CF at the beginning of 2042. The interest rate is 2.8%. What is the equivalent uniform amount for a series of end-of-year CFs spanning 2052-2056? (answer: $218.05)
b)Consider a $760 CF at the beginning of 2063. The interest rate is 3.9%. What is the equivalent uniform amount for a series of end-of-year CFs spanning 2050-2055? (answer: $87.88)
How do you work this out my hand to get the answer?
a.) Future Value of $762 at the beginning of the year 2052 = Present Value of annuity payment (2052-2056) at the beginning of the year 2052
Number of years = 10
Interest Rate = 2.8%
Using TVM equation;
FV = PV (1+r)n
FV = 762(1.028)10 = $1004.3524
Number of payments (n) = 5
Interest rate (r) = 2.8%
Let 'P' be the periodic payment
Then using PV of annuity formula
Solving for 'P', we get P = $218.05
b.) PV of $760 at the end of the year 2055 = FV of annuity payment (2050-2055) at the end of the year 2055
Number of Periods (n) = 7
Interest rate = 3.9%
Using TVM equation;
PV = FV/(1+r)n
PV = 760/(1.039)7 = $581.4398
Number of payments (n) = 6
Interest Rate (r) = 3.9%
Let 'P' be the periodic payment.
Using FV of annuity formula;
Solving for 'P', we get P = $87.88
