An industrial organization has bought a specialized machine for $240,000 which will save $36,000 each year for 10 years. Straight Line (SL) basis depreciation should be taken into consideration with a depreciable life of 10 years. After tax MARR is 10% per year. Effective income tax rate is 40%. After 10 years, the machine will have zero salvage value. a) Draw a table showing Before Tax Cash Flow (BTCF) and After Tax Cash Flow (ATCF). b) Calculate the after tax PW and IRR. (Use interpolation method to find IRR). Is it feasible?
| Year | gross income | initial investment & salvage value | before tax cash flow | depreciation | taxable income | taxes | after tax cash flow |
| 0 | -240000 | -240000 | 0 | -240000 | |||
| 1 | 36000 | 36000 | 24000 | 12000 | 4800 | 31200 | |
| 2 | 36000 | 36000 | 24000 | 12000 | 4800 | 31200 | |
| 3 | 36000 | 36000 | 24000 | 12000 | 4800 | 31200 | |
| 4 | 36000 | 36000 | 24000 | 12000 | 4800 | 31200 | |
| 5 | 36000 | 36000 | 24000 | 12000 | 4800 | 31200 | |
| 6 | 36000 | 36000 | 24000 | 12000 | 4800 | 31200 | |
| 7 | 36000 | 36000 | 24000 | 12000 | 4800 | 31200 | |
| 8 | 36000 | 36000 | 24000 | 12000 | 4800 | 31200 | |
| 9 | 36000 | 36000 | 24000 | 12000 | 4800 | 31200 | |
| 10 | 36000 | 0 | 36000 | 24000 | 12000 | 4800 | 31200 |


Since company uses straight line depreciation method



after tax IRR is 5.091%
Since after tax present worth at MARR of 10% is less than 0 and after tax IRR is less than MARR. investment in the above machine is not recommended
