Methodology

Four methodologies. One defensible number.

Every valuation method a qualified valuer would use, applied with the same academic framework and published industry data. No proprietary black boxes. Every assumption shown, sourced, and stress-testable.

Why four, not one

No single method produces a defensible valuation

A revenue multiple tells you what the market pays for turnover. An EBITDA multiple tells you what it pays for cash generation. An asset-based number gives you a floor. A DCF builds the value from forward expectations. Each answers a different question – and the confident-sounding number from any one method, on its own, is fragile.

A defensible valuation uses all four, weighted for the business profile, blended into a range. That’s the only way to produce a number that holds up when a buyer’s analyst, an investor’s associate, or a court-appointed valuer runs their own numbers against yours.

Method 01

Revenue multiple

The simplest and fastest method, useful for triangulation and for early-stage businesses where profit is reinvested.

What it measures

What the market is currently paying per dollar of annual turnover in your industry. Calibrated from actual transactions and public company trading multiples.

How we calculate it

  1. Start from the industry median revenue multiple, taken from the most recent Damodaran NYU Stern quarterly dataset for your industry classification.
  2. Adjust for business size: smaller businesses typically trade at a discount. Standard size bands: <$1M, $1M–$5M, $5M–$25M, $25M+.
  3. Adjust for revenue quality: recurring revenue earns a premium, transactional revenue trades at the median, one-off project revenue at a discount.
  4. Adjust for growth rate: faster growth than industry median earns a premium, slower growth takes a discount.
  5. Apply the adjusted multiple to your trailing twelve months revenue.

When it matters most

High-growth businesses where current profit understates future value. SaaS and subscription businesses. Pre-profitability companies with clear unit economics.

Known limitations

Ignores margin quality entirely. A business with 80% gross margin is treated the same as one with 20% gross margin at the same revenue. Always triangulated against EBITDA multiple to catch margin-quality differences.

Method 02

EBITDA multiple

The buyer’s default method. What most private-company transactions actually close at.

What it measures

What the market pays per dollar of normalised operating cash generation. This is what the buyer actually cares about: what the business will throw off in cash after they own it.

Normalising EBITDA

Reported EBITDA rarely equals cash-generating capacity. Typical normalising adjustments:

  • Owner compensation above or below market. If the founder takes a below-market salary, add back the difference. If they take an above-market salary, deduct it.
  • One-off items. Legal fees from a one-time dispute. Restructuring costs. Any non-recurring expense.
  • Related-party transactions. Above-market rent to a family-owned property. Below-market services from a sister company.
  • Non-operating income. Interest income, FX gains, gains on asset disposal.

How we apply the multiple

  1. Start from the industry median EBITDA multiple from Damodaran quarterly data.
  2. Size adjustment: same bands as revenue multiple, typically larger discount for small size because EBITDA-multiple transactions concentrate at the mid-market.
  3. Margin-quality adjustment: businesses with margins at or above industry median earn a premium; below-median margins take a discount.
  4. Apply adjusted multiple to normalised EBITDA.

When it matters most

Profitable businesses. Mid-market transactions. Any situation where the buyer will finance the acquisition with debt against the acquired cash flows (most private-company deals).

Method 03

Asset-based

The floor value. Rarely the headline number for a going concern, but it anchors the lower bound of the valuation range.

What it measures

The realisable value of the business’s assets, tangible and intangible, net of all liabilities. Think of it as: “if we sold the parts separately, what would we get?”

Tangible assets

Property, plant, equipment, inventory, cash, receivables. Adjusted for likely realisable value vs book value. Receivables discounted for collection risk. Inventory marked to net realisable value.

Intangible assets

  • Brand. Licensed comparable royalty rates, applied to revenue.
  • Customer lists & relationships. Multi-period excess earnings method for businesses with identifiable customer contracts.
  • Technology & IP. Replacement cost method for internally-developed software and processes.
  • Going-concern premium. The value of the assembled business as an operating unit, over and above the sum of its parts. Usually calibrated from the gap between EBITDA and asset values.

When it matters most

Asset-heavy businesses: manufacturing, real estate, specialised equipment. Distressed scenarios where the business isn’t generating cash. Holding companies. Estate valuations where the question is “what are the assets worth?”.

When it matters least

Asset-light services businesses: consulting, software, agencies, professional services. For these, asset-based value is often 10–20% of the blended valuation – useful as a floor, not the headline.

Method 04 · Detailed only

Discounted cash flow (DCF)

The methodology most private-equity investors and corporate finance teams use to validate a final number. Included only in Detailed reports.

What it measures

The sum of all future cash flows the business will generate, discounted back to present value using a risk-appropriate discount rate. Builds the valuation from the forward operating plan rather than from market multiples.

The 5-year explicit projection

For each of the next 5 years, we project:

  • Revenue growth. Starting from your own view, sanity-checked against industry growth rates.
  • Gross margin. Trending towards industry median unless you can defend otherwise.
  • Operating expenses. Typically growing at 60–75% of revenue growth rate, reflecting fixed-cost dilution as revenue scales.
  • Working capital requirements. Based on industry working-capital intensity.
  • Capital expenditure. Maintenance capex at industry norms, plus any growth capex needed to support the revenue plan.

The WACC discount rate

Weighted average cost of capital, built bottom-up:

  • Risk-free rate. 10-year government bond yield in your home currency.
  • Equity risk premium. Damodaran’s implied equity risk premium for your country.
  • Industry beta. Unlevered beta from Damodaran NYU Stern sector data, relevered for your capital structure.
  • Size premium. Small-company size premium from published studies (Duff & Phelps / Kroll). Typically 1.5–3% for sub-$25M businesses.
  • Specific-company premium. 0–3% for identified business-specific risks (concentration, key-person dependence, etc.).
  • Cost of debt. Risk-free plus industry-appropriate credit spread, after tax.

Terminal value

Gordon Growth Model: terminal value = final-year free cash flow × (1 + g) / (WACC − g), where g is the long-run sustainable growth rate. Capped at the projected long-term GDP growth rate for your economy (typically 2–3%).

Sensitivity analysis

The Detailed report includes a sensitivity grid showing how the DCF value changes with different WACC and terminal growth assumptions. This is the single most scrutinised page when a buyer’s analyst reads the report.

Blending the four methods

How we weight the methods for your business

No two businesses get the same weighting. The weighting reflects the business profile: what drives its value, what methodology a buyer would actually apply.

Business profile Revenue EBITDA Asset DCF
High-growth SaaS / subscription30%30%10%30%
Mature profitable services20%45%10%25%
Asset-heavy manufacturing15%30%30%25%
Pre-profitability / loss-making50%10%10%30%
Distressed / wind-down10%20%60%10%
Holding company / investment0%20%70%10%

The report shows your specific weighting with a one-paragraph explanation of why that weighting applies to your business.

Where the numbers come from

Published data, sourced and dated on every page

No proprietary data. No “our AI has determined.” Every industry multiple, benchmark, and rate in your report is traceable to a published, academically-respected source.

Damodaran NYU Stern dataset

Professor Aswath Damodaran publishes quarterly datasets from his position at NYU Stern School of Business. The global reference for industry multiples, betas, costs of capital, and margin benchmarks. Used by corporate finance teams, academics, and professional valuers worldwide. Refreshed every quarter, free to access, methodology fully transparent.

What we use it for: industry revenue multiples, EBITDA multiples, unlevered betas, margin benchmarks, cost of capital components.

IBISWorld industry reports

Industry-level revenue, margin, and growth statistics across 700+ industries in UK, US, Ireland, Canada, Australia, and New Zealand. Used for peer benchmarking and for sanity-checking the Damodaran industry classifications.

What we use it for: industry growth rates, operating margin distributions, working capital intensity, capital expenditure intensity.

National government bond yields

Risk-free rates pulled from the relevant central bank or treasury at the time your report is generated. Used as the starting point for the WACC build-up in the DCF.

What we use it for: risk-free rate component of WACC, by jurisdiction.

Published size premium studies

Size-premium data from the Duff & Phelps Valuation Handbook (now published by Kroll). Standard reference for the size discount applied in private-company valuation.

What we use it for: size premium component of WACC; size adjustment applied to market multiples.

Every table in your report cites which dataset, which classification, and which refresh date. Your accountant can verify every source independently.

Beyond the number

The 8-driver Value Builder Score

The valuation is a snapshot. The 8-driver framework is the diagnostic: where is value being created, where is it being eroded, what’s most worth fixing before you take the business to market.

01 · Financial performance

Margin, growth, and profitability trend vs industry. Buyers pay for stability and trajectory.

02 · Growth potential

Addressable market, pricing power, scalability of the operating model. Drives terminal value in the DCF.

03 · Monopoly control

Differentiation, defensibility, switching costs. Businesses with real moats trade at premium multiples.

04 · Recurring revenue

What percentage of revenue repeats without new sales effort. The single biggest driver of EBITDA-multiple premium in services businesses.

05 · Customer concentration

How much revenue depends on the top 3, 5, 10 customers. High concentration is the number-one reason valuations get discounted in due diligence.

06 · Owner dependence

How much the business depends on the founder personally. Sales, relationships, technical knowledge, decision-making. The thing buyers worry about most.

07 · Team health

Key-person risk beyond the founder. Retention, skill depth, succession readiness. Affects both valuation and deal structure.

08 · Switching costs

How hard it is for customers to move away. Data lock-in, integration depth, process fit. The driver of customer lifetime value in the DCF.

Methodology questions

For accountants and skeptical buyers

The methodology is the same. A competent accountant performing a valuation would use the four methods above, source from Damodaran, build a WACC the same way. What they add is judgment: arguing with the industry classification, interrogating the normalisation adjustments, sense-checking the size premium. For any transaction requiring a signed valuation for tax or court purposes, that human judgment is non-negotiable. For internal planning, early sale discussions, and fundraise anchoring, the automated version produces the same analytical output in minutes rather than weeks.
The questionnaire asks you to select your industry from the Damodaran NYU Stern classification (94 industries). The classification is the single most important input – multiples vary by 3–5× across industries. If you’re unsure which classification fits best, the questionnaire has a “my business fits multiple categories” option that runs the valuation under each and shows the sensitivity.
Risk-free rate from your jurisdiction’s 10-year government bond. Equity risk premium from Damodaran’s country-specific ERP. Beta from the Damodaran industry beta for your classification, relevered for your debt-to-equity ratio. Size premium from Duff & Phelps size-band data based on your revenue. Specific-company premium of 0–3% applied if the 8-driver score identifies concentration, owner dependence, or key-person risks at high levels. Cost of debt at risk-free plus your industry’s median credit spread, tax-shielded at your jurisdiction’s corporation tax rate.
In the Detailed workflow, yes. The questionnaire has an “advanced assumptions” step where you can override the default growth rate, margin trajectory, WACC components, and terminal growth rate. Every override is logged in the report so your accountant can see which numbers came from defaults and which came from your input. The scenario XLSX lets you adjust further after receiving the report.
The methodology applies to any business where the four methods make analytical sense. Businesses we don’t recommend Valuion for: regulated financial institutions (banks, insurers), businesses with more than 40% one-off project revenue, businesses in wind-down, businesses that require specialist appraisal (minerals, oil & gas reserves, fine art, biotech pre-revenue). For any of these, engage a specialist valuer directly.
Damodaran publishes updates in January, April, July, and October each year. We integrate each update within two weeks of publication. Risk-free rates are fetched from the relevant central bank or treasury at the time your report is generated. Your report shows the exact data vintage used so your accountant can verify it against the published source.

Methodology built to survive scrutiny.

Every number sourced. Every assumption shown. Every working checkable by your accountant, your buyer, or your investor.
