Valuation and Return Calculators
Estimate business value, normalize earnings, and compare investment returns using SDE, EBITDA, DCF, ROI, and purchase multiples.
Decision workflow
How to use this toolkit
- Normalize SDE or EBITDA.
- Select evidence-based low and high multiples.
- Cross-check with DCF or buyer return requirements.
- Reconcile enterprise value, debt, cash, and equity value.
Key terms
SDE
Owner-oriented earnings including one owner’s compensation and defensible add-backs.
EBITDA
Earnings before interest, taxes, depreciation, and amortization.
Enterprise value
The value of operations before deducting debt and adding excess cash.
Worked decision example
$300,000 of normalized SDE at 2.5x–3.5x implies $750,000–$1.05 million before reconciling inventory, working capital, debt, cash, and transaction-specific risks.
Common decision mistakes
- Unsupported add-backs create unsupported value.
- Match multiples to business size, date, industry, growth, and risk.
- Show a range instead of false precision.
