Four different machine manufacturers offered for hydraulic profile forming machine to be used in aluminum profile. The following analysis tables have been prepared for the four machines.

All machines will be scrapped after completing their 5-year life cycle. Since the scrap value of the machines will be a trivial amount, it does not need to be considered in calculations. A return on investment of at least 10 per cent is expected annually. Within the framework of the information given, which machine the profile manufacturer should invest in. State your calculations and reasons.
| m1 | m2 | m3 | m4 | |
| cost of machine | 24000 | 30400 | 49600 | 52000 |
| Life cycle years | 5 | 5 | 5 | 5 |
| Yearly expense | ||||
| electricity | 2720 | 2720 | 4800 | 5040 |
| labor | 26400 | 24000 | 16800 | 14800 |
| maintenance | 1600 | 1800 | 2600 | 2000 |
| insurance | 480 | 608 | 992 | 1040 |
| Total cost in the lifecycle | 180000 | 176040 | 175560 | 166400 |
| Benefit | 198000 | 193644 | 193116 | 183040 |
The total cost of a machine in its life cycle of 5 years = 5*(sum of yearly expenses)+cost of machine
ROI = ((Benefits - Costs)/Costs) * 100 = 10
Benefits = 0.1*Costs+Costs= Costs* 1.1
Example:
Total cost in the life cycle of Machine, M1 = 5*(2720+26400+1600+480)+24000 = 180000
Total benefits in its lifecycle = 180000*1.1 = 198000
Similarly, the life time benefits of the rest of the machines are calculated.
Comparing the lifetime benefits of the 5 machines, it is found that M1 has the highest benefit.
Hence, the manufacturer should invest in Machine, M1.
