Why build a disaggregated model, and at what level of detail
KnownMemorizeThe four areas of a model
| Area | Typical inputs | Feeds |
|---|---|---|
| Revenue | market size, share, segments, demand | income |
| Expense or margin | pricing power, materials and labor, margins | income |
| Asset growth and efficiency | working capital, fixed investment | net investment |
| Financing | debt versus equity, tenor and type | FCFE, interest, WACC weights |
Memory hook R-E-A-F: Revenue, Expenses, Assets, Financing. The first two make profit, the third spends it, the fourth pays for it.

MemorizeWhen disaggregation matters
Memory hook Same growth everywhere = same answer as a constant growth model.
Know it cold Different growth rates across components (margins changing, payout changing, investment out of line with revenue) → build the model. More lines: richer story, but more error, noise and updating.

Formulas
Quick example
Free cash flow to the firm of 40 and 44 in two years, a terminal value of 900 at the end of year 2, and a weighted average cost of capital of 10%. 40 ÷ 1.10 + 44 ÷ 1.10² + 900 ÷ 1.10² = 816.53, the value of the firm before subtracting debt.
- 944÷1.21=STO1 780.17 (year 2 flow and terminal value)
- 40÷1.1+RCL1= 816.53

Quick example
Next-year free cash flow to the firm of 50 and an enterprise value multiple of 14 times that cash flow give a firm value of 50 × 14 = 700.
- 50×14= 700

ENTER enter (on the HP, puts the number on the stack)
Quick example
Earnings per share grow 5% while the payout ratio goes from 20% to 25%. Dividends per share grow 1.05 × 25 ÷ 20 − 1 = 31.25%.
- 1.05×0.25÷0.2−1= 0.3125
- 1.05ENTER0.25×0.2÷1− 0.3125
ENTER enter (on the HP, puts the number on the stack)
Quick example
Revenue 200, cost of goods sold 110, selling, general and administrative expenses 40, depreciation and amortization 10, tax rate 30%. Operating profit is 40, so net operating profit after taxes is 40 × 0.70 = 28.
- 200−110−40−10=×0.7= 28
- 200ENTER110−40−10−0.7× 28
ENTER enter (on the HP, puts the number on the stack)
Quick example
Working capital rises by 5 and net long-term assets by 8, so net investment is 5 + 8 = 13.
Quick example
Net operating profit after taxes of 28 less net investment of 13 leaves free cash flow to the firm of 15.
- 28−13= 15
