The data below are estimated for the project study of a certain business investment. If money is worth 12%, what is the difference in Present Worth between the alternatives?
Alternative A: The initial investment is $3,500, with an annual revenue of $1,900. Annual disbursement amounts to $645 with no salvage value at the end of its life, which is 4 years.
Alternative B: The initial investment is $5,000 with an annual revenue of $2,500. Annual disbursements is $1,383 with no salvage value at the end of its useful life, which is 8 years.
CHOICES:
A. $154
B. 238
C. $39
D. $481
We have the following information
Alternative A
Initial investment = $3500
Annual revenue = $1900
Annual disbursement = $645
Life (n) = 4 years
Interest rate (i) = 12% or 0.12
Net present worth (NPW) = – Initial investment + Annual revenue(P/A, i, n) – Annual disbursement(P/A, i, n)
NPW = – 3500 + 1900(P/A, 12%, 4) – 645(P/A, 12%, 4)
NPW = – 3500 + 1900[((1+0.12)4 – 1)/0.12 (1+0.12)4] – 645[((1+0.12)4 – 1)/0.12 (1+0.12)4]
NPW = – 3500 + 5770.96 – 1959.09
NPW of Alternative A = $312
Alternative B
Initial investment = $5000
Annual revenue = $2500
Annual disbursement = $1383
Life (n) = 8 years
Interest rate (i) = 12% or 0.12
Net present worth (NPW) = – Initial investment + Annual revenue(P/A, i, n) – Annual disbursement(P/A, i, n)
NPW = – 5000 + 2500(P/A, 12%, 8) – 1383(P/A, 12%, 8)
NPW = – 5000 + 2500[((1+0.12)8 – 1)/0.12 (1+0.12)8] – 1383[((1+0.12)8 – 1)/0.12 (1+0.12)8]
NPW = – 5000 + 12419.10 – 6870.25
NPW of Alternative B = $550
Difference between the NPW of Alternative A and Alternative B
Difference = 550 – 312
Difference = $238
