Capital Budgeting for Valuations
Class 9: Capital Budgeting
Week 9 Overview: Capital Budgeting
The Big Picture
Capital budgeting is the process of deciding which investments/projects create value, by (1) projecting incremental after-tax cash flows, (2) choosing the right discount rate, and (3) applying a decision rule (with NPV as the workhorse).
Free Cash Flow (FCF)
The cash available after operating expenses and capital investments. Key formula: FCF = EBIT(1βt) + Depreciation β CAPEX β ΞNWC
Net Present Value (NPV)
Sum of all discounted future cash flows minus initial investment. Decision rule: Invest if NPV > 0
Terminal Value
Value at the end of forecast period. Either liquidation (sell assets) or perpetuity (continue forever at growth rate g).
Interest is already in the discount rate (WACC). Including it in cash flows = double counting!
Past R&D or expenses already incurred don't affect future decisions.
Increase in NWC = cash OUTFLOW (subtract). Decrease = inflow (add).
Tax is on capital GAIN (SV β BV), not the full sale price!
- Incremental revenues and costs
- Opportunity costs (foregone alternatives)
- Externalities (cannibalization, synergies)
- Depreciation (for tax shield calculation)
- CAPEX (capital expenditures)
- Changes in Net Working Capital
- Terminal/Salvage value
- Sunk costs (already spent)
- Interest expense (in WACC already)
- Overhead unaffected by project
- Financing cash flows
- Allocated costs not incremental
Discount nominal cash flows at nominal discount rates. Be careful: some items like depreciation have NO inflation even if sales/costs do. This mismatch is a common exam trap!

Depreciation reduces taxable income, creating tax savings even though it is not a cash expense.
- β Don't include interest expense β it is already in the discount rate (double counting).
- β Don't include sunk costs β they are not incremental.
- β Remember: Increase in NWC = cash outflow (subtract), Decrease = inflow (add).
