About the Business Valuation Calculator
The Business Valuation Calculator applies four valuation methods to the same set of inputs and surfaces a blended estimate alongside each individual result: Revenue Multiple, EBITDA Multiple, Seller’s Discretionary Earnings (SDE), and Asset-Based. Industry-specific multiples adjust automatically when you select the sector, and adjustments for growth rate, recurring revenue, and customer concentration are baked into the blended figure.
It is built for owner-operators thinking about an exit, founders fundraising and needing a defensible internal number, M&A advisors prepping a teaser, partners pricing a buyout, and CPAs assembling a starting point for estate or divorce work. SDE in particular is the lingua franca of Main Street acquisitions (businesses under ~$5M revenue); this tool surfaces it explicitly rather than burying it under generic “profit.”
All math runs locally in JavaScript. Revenue, profit, owner-comp, asset values, and every other deeply sensitive input stay on your device — no network call is made after first load, no value is logged, no figure is paired with your IP. Pre-deal valuation modeling generates some of the most strategically sensitive numbers a business will ever produce; they belong in your browser, not a cloud spreadsheet.
This is a directional estimate, not an appraisal. For any binding transaction — SBA-financed sale above $500K, partnership dispute, estate filing, divorce proceeding — commission a certified business appraiser (ASA, ABV, or CVA). The four methods diverging by more than 30% is a signal that the business has unusual structure (heavy assets, lumpy revenue, owner-dependent goodwill) that calculator multiples cannot capture cleanly.

How to Use the Business Valuation Calculator
Start by entering your annual revenue — the total top-line income your business generated in the last twelve months. Next, enter your net profit (earnings after all expenses) and your owner’s salary and benefits, which is the total compensation you pay yourself including health insurance, retirement contributions, and perks. The calculator uses these figures to derive Seller’s Discretionary Earnings (SDE), the metric most small-business buyers anchor their offers to.
Select your industry from the dropdown to apply industry-specific multiples, then set your average annual growth rate over the past three years. Growth rate significantly impacts every valuation method — a business growing at 30% per year commands far higher multiples than one that is flat. Finally, enter your total asset value, the percentage of recurring revenue, and your customer concentration data. Hit any input and the results update instantly across all four methods.
Understanding the Four Valuation Methods
Professional business appraisers never rely on a single method. Each approach captures a different dimension of value, and the most accurate picture comes from triangulating across multiple frameworks. Here is how each method works and when it is most applicable.
Revenue Multiple Method
The revenue multiple method values a business as a multiple of its annual revenue. It is the go-to method for high-growth companies that may not yet be profitable, or for industries where revenue scale matters more than current earnings. SaaS companies routinely trade at 3–8x revenue, while professional services firms typically command 1–3x. The multiple adjusts upward for high growth rates, high recurring revenue percentages, and low customer concentration. A SaaS business with 90% recurring revenue and 40% year-over-year growth might earn a 6–7x multiple, while the same revenue in a project-based agency might warrant only 1.5–2x. This method tends to produce the highest valuations for technology-driven businesses and the lowest for low-margin industries.
EBITDA Multiple Method
EBITDA — Earnings Before Interest, Taxes, Depreciation, and Amortization — is the gold standard for institutional buyers, private equity firms, and larger acquisitions. For small businesses, net profit serves as a reasonable proxy for EBITDA. Industry multiples range from 3–6x for service businesses to 8–15x for SaaS companies with strong unit economics. The EBITDA method rewards profitability: a business earning $500,000 on $2 million in revenue (25% margin) will value higher under EBITDA than a business earning $200,000 on the same revenue (10% margin), even though the revenue multiple method would value them identically. This is the method most buyers will anchor to for businesses with at least two to three years of stable earnings history.
Seller’s Discretionary Earnings (SDE) Method
SDE is the preferred method for owner-operated small businesses where the owner’s salary represents a significant portion of expenses. SDE equals net profit plus the owner’s salary and benefits — it represents the total economic benefit flowing to a single owner-operator. Typical SDE multiples range from 1.5x to 4x depending on industry, size, and growth. A freelance consulting practice earning $80,000 in profit with the owner paying themselves $120,000 has an SDE of $200,000, which at a 2.5x multiple yields a $500,000 valuation. This method is specifically designed for businesses under $5 million in revenue where a new owner would replace the existing one and capture that full SDE. For larger businesses with management teams, EBITDA is more appropriate.
Asset-Based Method
The asset-based approach values a business based on the fair market value of its tangible and intangible assets. It serves as a floor valuation — no business should sell for less than its liquidation value. This method is most relevant for manufacturing companies, real estate holdings, and businesses with significant physical inventory or equipment. The adjustment factor (0.7–1.3x asset value) accounts for the difference between book value and fair market value. Equipment depreciates on the books but may retain market value, while inventory might be worth less than its carrying cost. For service businesses with few tangible assets, this method typically produces the lowest valuation but still provides a useful reference point.
What Drives Business Value Up or Down
Buyers pay premiums for predictability and risk reduction. The single biggest value driver for most small businesses is recurring revenue — subscriptions, retainers, and long-term contracts that provide visibility into future cash flows. A business with 80% recurring revenue might command a multiple 50–100% higher than an identical business with entirely project-based income. Growth rate is the second most impactful factor: consistent double-digit growth signals market demand and operational competence. Customer concentration is the most common value destroyer — if your largest client represents more than 25–30% of revenue, buyers see existential risk and will discount their offer accordingly. Other value drivers include gross margin, owner dependency (can the business run without you?), documented processes, and defensible competitive advantages like intellectual property, exclusive contracts, or strong brand recognition.
When to Get a Professional Appraisal
This calculator provides a solid directional estimate using the same frameworks professional appraisers use, but there are situations where a formal business valuation (also called a business appraisal or BV engagement) is essential. If you are entering a sale or acquisition negotiation, going through a divorce, resolving a partnership dispute, or planning estate transfers, a Certified Business Appraiser (CBA) or Accredited Senior Appraiser (ASA) will produce a defensible opinion of value that holds up in legal proceedings. Professional appraisals typically cost $5,000–$20,000 and take 4–8 weeks. If the four methods in this calculator diverge by more than 50%, that is a strong signal that your business has unique characteristics that require professional judgment to value accurately.

Frequently Asked Questions
What is a typical small business valuation multiple?
Most small businesses sell for 2x to 4x SDE (Seller's Discretionary Earnings). Service businesses often trade at 2x to 3x, while recurring-revenue businesses like SaaS or managed services can command 4x to 8x. Revenue multiples generally range from 0.5x to 2x depending on industry and margin.
What is the difference between EBITDA and SDE?
EBITDA is earnings before interest, taxes, depreciation, and amortization, used primarily for businesses with $1M+ in profit and an absentee owner. SDE adds back a single owner's salary and benefits on top of EBITDA, making it the standard metric for owner-operated businesses under $5M in revenue.
How does customer concentration affect valuation?
Heavy customer concentration creates buyer risk. Businesses where one client represents more than 20% of revenue often see 10% to 30% valuation discounts. Buyers price in the likelihood of losing that client and the revenue that would disappear with them.
Does recurring revenue increase business value?
Yes, significantly. Businesses with 70%+ recurring revenue (subscriptions, retainers, contracts) can trade at 1.5x to 3x the multiple of a comparable project-based business because the revenue is predictable and requires less ongoing sales effort.
When should I hire a professional business appraiser?
Hire a certified appraiser when preparing for a sale above $500,000, settling a partnership dispute, going through divorce or estate planning, or when the four valuation methods diverge by more than 30%. Online calculators give a directional estimate, not a defensible number for legal or tax purposes.
