Business Valuation Calculator
Estimate a business's market value using a blended approach combining revenue multiples and net income projections. Useful for small business owners preparing for a sale, acquisition, or partnership negotiation.
About this calculator
This calculator uses a simplified blended valuation model averaging two common small-business valuation methods. The formula is: Value = (annualRevenue × industryMultiple + netIncome × (1 + growthRate / 100) × 5) / 2. The first component applies an industry revenue multiple — a figure representing what buyers typically pay per dollar of revenue in a given sector. The second component is an earnings-based valuation: projected next-year net income multiplied by a fixed earnings multiple of 5 (approximating a 20% capitalization rate). Averaging the two methods smooths the estimate between a top-line (revenue) and bottom-line (profit) perspective. Revenue multiples vary widely by industry — software companies may trade at 3–10×, while service businesses often fetch 0.5–1.5×. This tool provides a ballpark estimate; professional appraisals incorporate many additional factors.
How to use
Suppose a retail business has $800,000 annual revenue, $80,000 net income, a 10% expected growth rate, and a 0.75× industry revenue multiple. Revenue component: $800,000 × 0.75 = $600,000. Income component: $80,000 × (1 + 10/100) × 5 = $80,000 × 1.10 × 5 = $440,000. Blended value: ($600,000 + $440,000) / 2 = $520,000. This suggests an estimated business value of $520,000, giving the owner a starting benchmark before engaging a certified business appraiser or broker.
Frequently asked questions
What is an industry revenue multiple and how do I find the right one for my business?
An industry revenue multiple (also called a price-to-revenue or price-to-sales multiple) represents the typical ratio of business sale price to annual revenue in a specific sector. For example, a 1.5× multiple means buyers historically pay $1.50 for every $1.00 of annual revenue. Multiples vary enormously: SaaS and tech businesses can command 3–10×, while brick-and-mortar retail may be 0.3–0.75×. You can find industry benchmarks through business broker databases like BizBuySell, industry trade associations, or M&A advisory reports. A certified business appraiser or business broker can provide the most accurate multiple for your specific market and circumstances.
How accurate is a formula-based business valuation compared to a professional appraisal?
Formula-based valuations like this one provide a useful first estimate but are inherently simplified. They cannot account for qualitative factors that significantly affect value: customer concentration risk, owner dependency, intellectual property, brand strength, local market conditions, or recurring versus one-time revenue. Professional appraisals use methods such as discounted cash flow (DCF), comparable transactions analysis, and asset-based valuation, often combining multiple approaches and adjusting for dozens of specific risk factors. For informal planning or initial negotiations, a formula estimate is a reasonable starting point. For a binding sale, financing, legal dispute, or tax purposes, a certified business valuator (CBV) or accredited senior appraiser (ASA) is strongly recommended.
Why does growth rate affect business valuation and how should I estimate it honestly?
Growth rate affects valuation because buyers are paying not just for today's earnings but for future cash flows. A business growing at 20% annually is worth more than one growing at 2%, as the buyer anticipates higher future income. In this formula, growth rate scales projected next-year net income, so higher growth directly increases the income-based valuation component. When estimating growth rate, use your actual compound annual growth rate (CAGR) over the past 2–3 years rather than aspirational projections. Unsupported high growth assumptions are a common mistake that leads to unrealistic valuations and failed negotiations. Buyers will scrutinize historical financials closely, so conservative, defensible estimates build credibility.
