How do I calculate the terminal value?

The firm is looking to expand its operations by 10% of the firm's net property, plant, and equipment. The estimated life of new PPE will be 12 years. The salvage value of the equipment will be 5% of the PPE. The annual EBIT for this new project will be 18% of the project's cost. Expansion is 10% of 2017 net PPE 10% * 114,178,000 = 11,417,800 Salvageable value is 5% of expansion cost 5% * 11,417,800 = 570,890 Depreciation will be cost-salvage value / est. life 11,417,800 - 570,890 = 10,846,910 / 12 = 903,909 Annual EBIT will be 18% of the new PPE 18% * 11,417,800 = 2,055,204

WACC is 3%

I calculate operating cash flow as 2,239,792 and

DCF year 0-12 as $2,239,792 > $2,174,555.34 > $2,051,467 > $1,882,080 > $1,665,558 > $1,435,826 > $1,196,521 > $972,782 > $765,970 > $589,207 > $439,707 > $318,628 > $222,817 (year 12)
