15.a Calculate the FV of (a) an ordinary annuity and (b) an annuity due with payments of $2,000 at the interest rate of 12% per year. (a) $( ); (b) $( )
15.b Calculate the PV of (a) an ordinary annuity and (b) the annuity due with 5 payments of $2,000 at the interest rate of 12%. (a) $( ); (b) $( )
(Please hand write and show all steps of the solution no Excel no typing I need to see all steps)
15 a.
Ordinary annuity, payments are made at end of each period
FV = P(1+r)n-1 +....+ P(1+r)2 + P(1+r) + P = P[(1+r)n -1]/r
where, P = 2000
r = 12% = 0.12
n = 5
=> FV = 2000(1.125 - 1] /0.12 = $12705.69
Annuity due, payments are made at starting of each period
FV = P(1+r)n +....+ P(1+r)2 + P(1+r) = P [((1 + r)n - 1) / r])(1 + r)
where, P = 2000
r = 12% = 0.12
n = 5
=> FV = 2000((1.12)5 - 1) / 0.12)(1.12) = $14230.37
12 b.
Ordinary annuity,
PV = P/(1+r) + P/(1+r)2 +....+ P/(1+r)n = P[1- (1+r)-n]/r
where, P = 2000
r = 12% = 0.12
n = 5
=> PV = 2000(1- 1.12-5]/0.12 = $7209.55
Annuity Due,
PV = P + P/(1+r) +....+ P/(1+r)n-1 =P + P[1- (1+r)-(n-1)]/r
where, P = 2000
r = 12% = 0.12
n = 5
=> PV = 2000 + 2000(1- 1.12-4]/0.12 = $8074.70
