Explanation:
Formula for PV of ordinary annuity is:
PV = P x [1-(1+r) -n/r]
P = Periodic cash flow
r = Rate of interest
n = Number of periods
a.
P = $ 800; r = 0.1; n = 10
PV = $ 800 x [1 – (1+0.1)-10/0.1]
= $ 800 x [1 – (1.1) -10/0.1]
= $ 800 x [(1 – 0.385543289429531)/0.1]
= $ 800 x (0.614456710570469/0.1)
= $ 800 x 6.14456710570469
= $ 4,915.65368456375 or $ 4,915.65
b.
P = $ 400; r = 0.05; n = 5
PV = $ 400 x [1 – (1+0.05)-5/0.05]
= $ 400 x [1 – (1.05) -5/0.05]
= $ 400 x [(1 – 0.783526166468459)/0.05]
= $ 400 x (0.216473833531541/0.05)
= $ 400 x 4.32947667063082
= $ 1,731.79066825233 or $ 1,731.79
c.
P = $ 800; r = 0; n = 5
As the time value is zero, PV of annuity will be same with total payment from year 1 through 5.
PV = $ 800 x 5 = $ 4,000
d.
Formula for PV of annuity due is:
PV = P + P x [1-(1+r) –(n-1)/r]
P = Periodic cash flow
r = Rate of interest
n = Number of periods
i)
P = $ 800; r = 0.1; n = 10
PV = $ 800 + $ 800 x [1 – (1+0.1) -(10-1)/0.1]
= $ 800 + $ 800 x [1 – (1.1) -9/0.1]
= $ 800 + $ 800 x [(1 – 0.424097618372485)/0.1]
= $ 800 + $ 800 x (0.575902381627515/0.1)
= $ 800 + $ 800 x 5.75902381627515
= $ 800 + $ 4607.2190530201
= $ 5,407.2190530201 or $ 5,407.22
ii)
P = $ 400; r = 0.05; n = 5
PV = $ 400 + $ 400 x [1 – (1+0.05) -(5-1)/0.05]
= $ 400 x $ 400 x [1 – (1.05) -4/0.05]
= $ 400 x $ 400 x [(1 – 0.822702474791882)/0.05]
= $ 400 x $ 400 x (0.177297525208118/0.05)
= $ 400 + $ 400 x 3.54595050416236
= $ 400 + $ 1,418.38020166494
= $ 1,818.38020166494 or $ 1,818.38
iii)
P = $ 800; r = 0; n = 5
As the time value is zero, PV of annuity will be same with total payment from year 1 through 5.
PV = $ 800 x 5 = $ 4,000
