wᵈ × rᵈ(1−T) + wᵖ × rᵖ + wᵉ × rₑ
Weighted average cost of capital. Use market value weights. Only debt gets the tax shield.
rₑ = Rᶠ + β(Rₘ − Rᶠ)
Risk-free rate plus beta times market risk premium. Beta measures systematic risk only.
P₀ = D₁ / (rₑ − g)
Constant-growth dividend discount model. Requires g < rₑ. D₁ = D₀ × (1 + g).
EBIT(1 − T) + Depreciation − Capital Expenditures − ΔNet Working Capital
Cash flow available to all capital providers. Discount at WACC for enterprise value.
TV = FCFₙ × (1 + g) / (r − g)
Value of all cash flows beyond the forecast period. Small changes in g or r have outsized impact.
Σ [CFₜ / (1 + r)ᵗ] − Initial Investment
Accept if NPV > 0. Gold standard for capital budgeting. Always preferred over IRR for mutually exclusive projects.
Market Cap + Total Debt + Preferred Stock + Minority Interest − Cash
Total acquisition cost. Use with EV-based multiples (EV/EBITDA, EV/Revenue).
EBIT / (EBIT − Interest Expense)
% change in EPS for a 1% change in EBIT. Higher DFL = more debt = more financial risk.
| Method | Formula / Rule | Strengths | Weaknesses |
|---|---|---|---|
| NPV | Σ PV of CFs − Investment; Accept if > 0 | Accounts for TVM, measures $ value added | Requires estimated discount rate |
| IRR | Rate where NPV = 0; Accept if > WACC | Percentage return, intuitive | Multiple IRRs possible, reinvestment assumption |
| Payback | Years to recover investment | Simple, measures liquidity risk | Ignores TVM and post-payback CFs |
| PI | PV of CFs / Investment; Accept if > 1 | Value per $ invested, useful for rationing | Same limitations as NPV |
| Multiple | Formula | Best For |
|---|---|---|
| P/E | Stock price / EPS | Profitable companies with stable earnings |
| EV/EBITDA | Enterprise value / EBITDA | Comparing across capital structures |
| P/B | Stock price / Book value per share | Asset-heavy industries (banks, REITs) |
| P/S | Stock price / Revenue per share | Early-stage or unprofitable companies |
| EV/Revenue | Enterprise value / Revenue | SaaS and high-growth sectors |
Steps to calculate free cash flow to the firm: start with EBIT, subtract taxes, add back depreciation, subtract CapEx and working capital changes.
When NPV and IRR conflict on mutually exclusive projects, always choose NPV. It maximizes firm value in dollar terms.
