How to Use This Business Valuation Calculator
Our business valuation calculatorgives every business owner access to the same core methodologies used by investment bankers, M&A advisors, and certified business appraisers. Instead of paying thousands of dollars for a preliminary estimate, you can run all four methods in minutes and understand the full range of what your company might be worth. Whether you are planning to sell, bringing in a partner, applying for an SBA loan, or simply benchmarking your progress, knowing your business value is the starting point for every major financial decision.
The Valuation Methods tab lets you focus on one method at a time. Each method has its own input panel and result card so you can isolate the assumptions behind each estimate. The Comparisontab runs all four methods simultaneously using a shared set of inputs and displays the results side by side, along with a valuation range and a weighted average slider. Together, these two views give you a complete picture of your company’s value.
To get the most accurate estimate from this company valuation calculator, use your most recent 12 months of financial data. For net income, consider using seller’s discretionary earnings (SDE), net income plus owner salary, owner benefits, depreciation, amortization, and one-time expenses, rather than the raw bottom line from your tax return. SDE is the standard input for small business earnings multiples because it represents the full economic benefit available to a new owner-operator.
For the discounted cash flow method, free cash flow (operating cash flow minus capital expenditures) is the appropriate input rather than net income or revenue. If you need help calculating your company’s EBITDA before moving to valuation, our EBITDA calculator walks you through every add-back line by line.
The Four Business Valuation Methods Explained
Understanding when and why to use each method is the key to getting a reliable estimate from any small business valuation calculator.
Earnings Multiple (SDE or EBITDA Multiple): This is the most widely used method for profitable small businesses. You multiply annual net income (or SDE) by an industry-specific multiple. According to the IRS guidance on business valuation, most small businesses sell for 2 to 4x SDE, though technology and SaaS businesses frequently command higher multiples. The multiple reflects buyer confidence in the sustainability and growth potential of earnings. A business with diversified customers, recurring revenue, and strong management typically earns a higher multiple than one dependent on a single customer or the owner’s personal relationships.
Revenue Multiple: This method is common for high-growth or pre-profit companies where earnings are not yet a reliable indicator of value. SaaS businesses are the most prominent example; buyers pay for annual recurring revenue (ARR) growth and net revenue retention, often at 3 to 8x revenue or higher for fast-growing companies. Revenue multiples for brick-and-mortar businesses like retail or food service are much lower (0.3 to 0.8x) because margins are thin and revenue growth is slower.
Asset-Based: This method calculates net asset value, total assets minus total liabilities; and adds goodwill or intangible value for brand, customer lists, patents, or proprietary technology. It is most appropriate for asset-heavy businesses (manufacturing, real estate, equipment dealers) and typically produces the lowest valuation for service or software businesses, where most of the value lies in cash flow generation rather than hard assets. For companies with negative or minimal earnings, the asset-based method often serves as a floor valuation.
Discounted Cash Flow (DCF): DCF is the theoretically most rigorous method. It projects annual free cash flows over a 5 to 10 year period using a growth rate, discounts each year back to present value using your required rate of return (discount rate or WACC), and adds a terminal value to capture cash flows beyond the projection window. For context on how to calculate WACC for your business, see our WACC calculator. DCF is highly sensitive to the growth rate and discount rate inputs, so modest changes in assumptions can produce dramatically different outputs, use conservative estimates to avoid overvaluing your business.
What Drives Business Value: Key Factors in Any Business Value Calculator
No business value calculator can fully capture every driver of value, but understanding the qualitative factors helps you contextualize the quantitative output. Buyers and appraisers evaluate several dimensions beyond raw financial performance.
Revenue quality and concentration: A business where 60% of revenue comes from a single customer is worth significantly less than one with 500 customers, none representing more than 5% of revenue. Buyers discount heavily for customer concentration risk because the loss of one key client could devastate earnings overnight. Recurring revenue (subscriptions, maintenance contracts, retainer agreements) commands a premium because it provides visibility into future cash flows.
Owner dependence:If the business cannot operate without the current owner’s direct involvement with customers, suppliers, or employees, buyers will apply a significant discount or require an extended earnout period. Businesses with documented processes, a capable management team, and systems that run independently of the founder trade at higher multiples because the transition risk is lower.
Growth trajectory: A business with three years of consistent revenue growth is worth more than one with flat or declining revenue, even if current earnings are similar. Buyers pay for future earnings, not past performance, and a strong growth trajectory signals that the multiple applied today will be supported by higher cash flows tomorrow. Our break-even calculator can help you illustrate how new revenue growth translates into accelerating profitability.
Margins and scalability: High gross margins, particularly above 50%, indicate pricing power and the ability to absorb cost increases without eroding profit. Scalable business models, where additional revenue can be captured with minimal incremental cost, command higher multiples than those with fixed cost structures that grow linearly with revenue. Use our profit margin calculator to benchmark your margins against industry standards before entering valuation discussions.
Industry Multiples and Benchmarks for Your Small Business Valuation Calculator
Industry multiples vary widely, and using the wrong benchmark will produce a misleading estimate from any small business valuation calculator. The table below summarizes typical earnings and revenue multiples by sector based on transaction data from business brokers and M&A databases.
SaaS / Software: Earnings multiples of 5 to 10x EBITDA (or higher for high-growth ARR businesses); revenue multiples of 3 to 8x. The premium reflects recurring revenue, high gross margins, and software scalability. Public SaaS comps trade at even higher multiples, but private company discounts of 20 to 40% are typical for illiquidity.
Professional Services (Consulting, Accounting, Legal): Earnings multiples of 2 to 4x SDE; revenue multiples of 0.5 to 1.5x. Client portability, whether relationships follow the owner or the firm, is the biggest variable. Firms with strong brand recognition and team-based delivery trade at the high end.
Manufacturing: Earnings multiples of 3 to 5x EBITDA; revenue multiples of 0.5 to 1.5x. Asset values, proprietary processes, and long-term customer contracts drive premiums. Capital intensity means buyers look closely at maintenance capex and equipment age.
Retail / Food & Beverage: Earnings multiples of 1 to 3x SDE; revenue multiples of 0.3 to 0.8x. Thin margins and high competition compress multiples. Location, lease terms, and foot traffic data are critical inputs that no online calculator can fully model.
The SBA business valuation guidance recommends using multiple methods and weighting them based on the nature of the business, exactly the approach our Comparison tab is designed to facilitate.

Preparing for a Formal Business Valuation: What This Calculator Cannot Do
Our business valuation calculator is a powerful starting point, but certain uses require a formal appraisal by a credentialed professional. The IRS requires a qualified written appraisal for business interests transferred by gift or estate, and courts expect certified valuations in divorce or shareholder dispute proceedings. According to IRS business valuation guidance, valuations must consider all relevant factors including the company’s economic outlook, financial condition, earning capacity, dividend-paying capacity, and the economic outlook for the industry.
A certified valuator will conduct a site visit, review three to five years of financial statements, interview management, analyze customer contracts, benchmark against comparable transactions, and prepare a written report that can withstand scrutiny from the IRS, a court, or a sophisticated buyer’s legal team. The cost typically ranges from $3,000 for a simple small business to $25,000 or more for a complex multi-location company. The investment is justified whenever the stakes are high and the decision is irreversible, such as a sale, a partnership buyout, or a major estate transfer.
Before engaging a valuator, use this business valuation calculator to develop informed expectations, identify which method is most relevant to your industry, and understand the key financial drivers that influence your multiple. Owners who understand the valuation process tend to get better outcomes because they know which levers to pull, improving revenue quality, reducing owner dependence, and documenting processes, in the years leading up to a sale. Pair this calculator with our EBITDA calculator to optimize the earnings figure that anchors your valuation, and use our profit margin calculator to ensure your margins are competitive within your industry before going to market.
