Business Valuation: Complete Guide to the 4 Methods (DCF, Multiples, Transaction, Asset)

Business valuation is not a number. It’s a probabilistic range generated by the intersection of four independent methods. Anyone claiming a single “true value” is either selling something or doesn’t know the craft. This guide explains the four methods every professional dealmaker uses in parallel: DCF, market multiples, transaction comps, asset-based. When they dominate, how to calculate them, where they fail.

By the end, you can read an advisor’s valuation and tell whether it’s solid or inflated. You can also produce a credible preliminary valuation in 2 hours.

Why you need four methods, not one

Each method has structural biases. Using only one means accepting its systematic errors. Using all four allows triangulating the real value range. Professional pattern:

1. Calculate the 4 values independently
2. See where they converge and where they diverge
3. If 3 out of 4 converge → tight range, high confidence
4. If they diverge significantly → investigate why (each tells you something different about the business)

Method 1 — Discounted Cash Flow (DCF)

DCF is “intrinsic” valuation: what future cash flows are worth discounted to present. It’s the principal method for cash-generative businesses, asset-light, with visible growth prospects.

How it works, simply

You project Free Cash Flows for 5-10 years, calculate Terminal Value (value beyond horizon), discount everything at WACC.

Free Cash Flow = EBITDA − Taxes − Working Capital Change − CapEx

Terminal Value (Gordon method) = FCF year N+1 / (WACC − g), where g = perpetual growth rate (typically 1-2%)

WACC for Italian mid-market SME: 8-12% typical.

Equity Value = sum of discounted FCFs + discounted TV − Net Debt + Cash

Where DCF excels

• Businesses with predictable flows (recurring revenue, multi-year contracts)
• Asset-light companies (software, B2B services)
• Sectors without recent transaction comps
• Internal valuations for strategic decisions

Where DCF fails

• Extreme sensitivity to WACC: +1% WACC = −10/15% value
• Terminal Value often worth 60-70% of total → one “g” error changes everything
• Difficult for cyclical businesses (FCF volatility makes projections unreliable)
• Useless for structurally loss-making businesses (negative FCF)

Method 2 — Market multiples (Trading comps)

Multiples are the “relative” method: what your company is worth compared to similar listed companies or recent transactions in the same sector.

The 4 multiples that count in mid-market

How to select comparable companies

Peer comparables must share:

• Sector (sub-sector granularity, not “technology” generic)
• Size (EBITDA within 30-200% of yours)
• Geography (Europe for Italian mid-market SME)
• Growth profile (similar growth, ±5% CAGR)
• Capital structure (similar leverage)

Look for 6-12 peer comparables, calculate mean + median, apply spread.

Method 3 — Transaction comps (Precedent transactions)

Transaction comps use multiples actually paid in recent deals in your sector. The most “realistic” method because it reflects what buyers actually paid.

When they dominate

• Sectors with 3+ comparable transactions in last 24 months
• Markets in active consolidation
• Final validation before going to market

Control premium

Transaction comps include control premium (typically 20-30% above trading comps), which is what a buyer pays to obtain 100% of a company vs minority participation.

Method 4 — Asset-based valuation

Asset-based method values all assets (current + fixed) minus all debts. It’s the “floor” of value — never drops below this (with exceptions).

When it dominates

• Real estate company (NAV-based valuation)
• Holding with asset portfolio
• Companies in liquidation or pre-bankruptcy
• Operating company with dominant tangible assets

Final triangulation — how the valuation composes

The range matters more than the single number. A good professional valuation communicates both.

How to read an advisor’s valuation

When an advisor delivers a valuation, verify these 5 quality signals:

1. All 4 methods calculated (not just “market multiples”)
2. Explicit range, not single number
3. Clear and modifiable assumptions (WACC, growth rate, perpetuity rate, peer list)
4. Stress test on 3 scenarios (base / bull / bear)
5. Sensitivity analysis on main drivers

If these elements are missing, the valuation is marketing, not analysis.

Common founder self-valuation mistakes

1. Using non-normalized EBITDA: contains 15-30% of family compensation, above-market salaries, private costs. Buyer doesn’t pay them.
2. Using US/UK multiples: inflate by 20-30%. Stay with European peers.
3. Confusing Enterprise Value with Equity Value: price received is equity (EV − net debt).
4. Not considering working capital adjustment: at closing, working capital different from “target” changes cash price by 5-15%.
5. Expecting strategic premium without strategic buyer: synergistic premium exists only if you sell to industrial. PE doesn’t pay it.

Frequently Asked Questions

How much does professional valuation cost for an Italian SME?

Typical ranges: $3-8k for preliminary estimate (5-10 pages); $15-40k for complete fairness opinion with 4 methods + detailed DCF + sensitivity (60-100 pages, formal for M&A or equity raise); $50-150k for “courtroom-ready” valuation with sworn report.

Can I value my company alone with Excel?

For preliminary estimate yes: 2-4 hours of work + online template give you a plausible range ±20%. For operational decisions (sale, equity raise, litigation) no: needs third-party advisor for credibility with counterparties, methodological validation, defensibility in negotiation.

How is WACC calculated for an Italian SME?

Simplified pattern: WACC = Risk-free rate (Italian 10Y BTP ~3.5%) + Equity Risk Premium (5-7% Italy) × Beta sector + Country Risk premium (0.5-1.5%). For illiquid SME, add Size Premium (1.5-3%). Typical final WACC: 9-12% for Italian mid-market SME.

How much does debt weigh in valuation?

100% because Equity Value = EV − Net Debt. Net debt = Financial debt − Cash. Includes: bank mortgages, financial leases, factoring pro-soluto, shareholder loans. Does NOT include: physiological working capital, supplier debts.

Who sees synergies?

Industrial strategic buyer sees and pays them, up to 30-40% more above financial fair market value. PE generally does NOT pay them (at most recognizes “no-regret” cost synergies). Therefore, structure the process to attract strategic buyers if you have real identifiable synergies.

How do I handle intangible assets (brand, patents)?

Three options: (1) incorporated in multiples — sector premium; (2) separate valuation (royalty relief, replacement cost); (3) asset spin-off for IP licensing post-deal. For luxury brand or pharmaceutical patents, can be worth 30-50% of total company value.
