Discounted Profitability Criteria
Discounted Profitability Criteria Same basis for criteria as before except we use the discounted cash flows and discounted cumulative cash flow diagram
Discounted Profitability Criteria Cash Basis CCP Net Present Value, NPV CCR Present Value Ratio, PVR
Discounted Profitability Criteria Time Basis PBP Discounted Payback Period, DPBP DPBP = time required, after start-up, to recover the fixed capital investment, FCIL, required for the project, with all cash flows discounted back to time zero.
Discounted Profitability Criteria Interest Basis ROROI Discounted Cash Flow Rate of Return, DCFROR DCFROR = interest or discount rate for which the NPV of the project is equal to zero.

Using CAPCOST for Profitability Calculations Go to COM summary worksheet Rework Example 10.1 using CAPCOST Land = 10 FCIL = 150 (year 1 = 90 and year 2 = 60) WC = 30 R = 75 COMd = 30 t = 45% S = 10 Depreciation = MACRS over 5 years Project life, n = 10 years after start-up Discount (interest) rate = 10% Go to COM worksheet and manually enter the above costs. Note that COMd is not a separate entry but is made up of CUT, COL, CWT, FCI, CRM. The easiest way to solve this problem is to adjust the multipliers for the COMd equation (0FCI +0COL +1(CUT+ CWT + CRM) and lump all the costs into CRM
