We need to find which alternative will have highest Equivalent annual benefit

Statement showing Equivalent annual benefit if machine is kept for 1 year

Particulars 0 1 Total
Cost -56250    
Annaul operating Cash flow   15625  
Abandonment Value   43750  
Total cash flow -56250 59375  
PVIF @ 11% 1.0000 0.9009  
PV -56250 53490.99 -2759.01
PVIF(11%,1)     0.9009

Equivalent Annual Benefit             405.42

Thus Equivalent Annual Benefit = 405.42 $

Thus in year 3  Equivalent Annual Benefit is highest and hence 3 years is economical life of machine

Note :  Equivalent Annual Benefit = Total of PV / PVIFA
