Business valuation is rarely straightforward—the method an advisor chooses can swing your company's appraised worth by 20–40% or more. Different advisory firms lean on distinct methodologies depending on your industry, deal structure, and end goal, so knowing what separates an income-based valuation from a market-based one could mean thousands in your pocket. This guide breaks down the main approaches and shows you which advisors typically use them.
The Three Core Valuation Methods
Advisors generally work from three foundational frameworks, often blending them to triangulate a fair value. Understanding the differences helps you spot whether a firm is taking a balanced approach or relying too heavily on a single lens.
Income Approach (Discounted Cash Flow)
The income approach values your business based on the cash it's expected to generate. An advisor projects future earnings, applies a discount rate (typically 8–15% for mid-market firms), and calculates present value. This method is most common in SaaS, recurring revenue, and professional services valuations because predictable cash flows are the core asset.
Advisors who favor this approach often include Big Four firms (Deloitte, EY, PwC), boutique investment banks, and specialist tech/healthcare valuators. Expect this method when you're selling to a financial buyer or seeking a bank loan.
Market Approach (Comparable Companies & Transactions)
Here, advisors benchmark your business against recent comparable sales and public company multiples. They'll look at EBITDA multiples, revenue multiples, and other metrics from similar companies in your sector. For a SaaS company, this might mean analyzing 10–15 comparable acquisitions from the last 18–24 months.
This approach works best when robust comparable data exists—common in tech, healthcare, and consumer sectors. Real estate investment bankers and mid-market M&A advisors rely heavily on this method because it ties value to actual market signals.
Asset Approach
The asset-based method calculates the fair market value of tangible and intangible assets, minus liabilities. It's less popular for growing companies but essential for capital-intensive industries (manufacturing, real estate) or distressed situations. Liquidation specialists and turnaround advisors often anchor here.
Which Advisor Types Use What
Different advisory firms tend to favor specific methodologies based on their expertise and client base.
Investment Banks (mid-to-large deals $10M+): Typically use all three methods, with heaviest weight on market and income approaches. They'll produce a 50–100-page fairness opinion backed by detailed financial modeling.
Boutique Valuation Firms: Often specialize in one or two approaches and industry verticals. A healthcare valuation boutique might excel at income-based analysis for physician practices, while a tech specialist focuses on SaaS metrics and comparable transactions.
Accounting & Big Four Firms: Blend all three methods, offering credibility for tax, litigation, or financing purposes. Their fee structure typically ranges from $15,000–$75,000+ depending on complexity and scope.
Broker-Dealers & M&A Intermediaries: Heavy reliance on market comparables because they're actively buying and selling. They'll say "similar companies sold at 6.5x EBITDA last quarter," making this approach feel concrete and current.
CFO Advisory & Consulting Firms: Use income-based DCF heavily, especially when structuring growth projections and stress-testing assumptions. Common for internal valuations and board presentations.
What to Look For When Hiring
Before engaging an advisor, confirm they explain their methodology hierarchy—which approach gets 50% weight and why. Ask for anonymized case studies in your industry showing how their valuation compared to the actual sale price. A credible advisor will openly discuss past estimates that differed from final deal value and explain why.
Pricing varies widely:
- Simple valuations: $5,000–$15,000
- Mid-market due diligence: $25,000–$75,000
- Complex transactions with litigation support: $75,000+
Timeline matters too. A quick sanity-check valuation takes 2–4 weeks; a rigorous fairness opinion can take 8–12 weeks.

Frequently Asked Questions
Q: Which valuation method is most defensible in court? A: A triangulated approach using all three methods (income, market, and asset) with documented assumptions is hardest to challenge, particularly if prepared by a Big Four or nationally recognized valuation expert.
Q: How often should I get my business revalued? A: For a growing company, annually or before major financing rounds; for stable businesses, every 2–3 years unless significant market or operational changes occur.
Q: Can a small business use discounted cash flow valuation? A: Yes, but only if you have 3+ years of consistent financials and can reasonably project 5–10 years ahead; otherwise, a market or asset-based approach often fits better.
