Compute EAC where the machine is replaced for 3 years & EAC for 4 years and select the replacement period with lower EAC.
EAC = PV of net cashflows / PVAF (r%, n yeasr )
where r is discount factor & n is no. of yeasr for replacement.
If replacement period is 3 years:
If replacement period is 4 years:
EAC if maintained for 4 years is less compared to EAC where machine is replaced for 3 years.
Thus it is advicable to raplace after 4 years rather than 3 years.
