With the estimates shown below, Sarah needs to determine the trade-in (replacement) value of machine X that will render its AW equal to that of machine Y at an interest rate of 11% per year. Determine the replacement value.
Machine X | Machine Y | |
Market Value, $ | ? | 86,000 |
Annual Cost, $ per Year | −57,500 | −40,000 for year 1,increasing by 2000 per year thereafter. |
Salvage Value | 15,500 | 20,000 |
Life, Years | 3 | 5 |
The replacement value is ________$ .
AW of machine Y = -86000*(A/P,11%,5) - 40000 - 2000*(A/G,11%,5) + 20000*(A/F,11%,5)
= -86000*0.270570 - 40000 - 2000*1.792259 + 20000*0.160570
= -63642.14
Let trade in value be P, then
AW of X = -P*(A/P,11%,3) - 57500 + 15500*(A/F,11%,3)
= -P*0.409213 - 57500 + 15500*0.299213
As per given condition
-P*0.409213 - 57500 + 15500*0.299213 = -63642.14
P = (63642.14 - 57500 + 15500*0.299213) / 0.409213 = 26343.11
