(Straight Line Depreciation) A new machine cost $100,000, and will increase inventory by $10,000, A/R by $15,000, and A/P by $5,000. This machine will reduce our expenses by $18,000 per year. The machine will be depreciated to a zero book value in 10 years, but could be sold for $12,000 at the end of 10 years. The marginal tax rate is 35%, and the cost of capital is 12%. Calculate the payback, NPV, IRR, and PI.
Step 1: Calculate depreciation schedule:
| Depreciation Schedule | ||||
| Year | Opening Balance | Investment | Depreciation | Closing balance | 
| - | 100000-12000= 88,000.00 | 88,000.00 | ||
| 1.00 | 88,000.00 | 88000/10= 8,800.00 | 79,200.00 | |
| 2.00 | 79,200.00 | 8,800.00 | 70,400.00 | |
| 3.00 | 70,400.00 | 8,800.00 | 61,600.00 | |
| 4.00 | 61,600.00 | 8,800.00 | 52,800.00 | |
| 5.00 | 52,800.00 | 8,800.00 | 44,000.00 | |
| 6.00 | 44,000.00 | 8,800.00 | 35,200.00 | |
| 7.00 | 35,200.00 | 8,800.00 | 26,400.00 | |
| 8.00 | 26,400.00 | 8,800.00 | 17,600.00 | |

| 10.00 | 8,800.00 | 8,800.00 | - | |
Step 2: Calculate annual CF:

| CF | 14780 | 14780 | |
| Wcinv Recovery | increase in inventory+ increase in AR -increase in AP | 20000 | |
| Salvage value | sale value of investment | 12000 | |
| Tax on profit of sale | 0.35x12000 (as equipment is completely depreciated, entire salvage value is profit) | 4200 | |
| Total CF | Wcinv Recovery+Salvage value-Tax on profit of sale | 14780 | 52580 | 
Step 3: Calculate NPV & PI
