Business Appraisal Calculator

Think of a business appraisal like pricing a rental property. You would not just look at what the building cost to build (assets), or what similar buildings sold for (revenue comps). You would also look at what rent it generates and whether that rent is growing. A business valuation works the same way: three lenses, each telling a different part of the story.

The revenue multiple method asks: for every dollar of sales this business generates, what would a buyer pay? In retail, that might be 50 cents. In software, it might be $2. The ratio reflects how predictable, scalable, and margin-rich that revenue is. High-margin, recurring revenue commands a higher multiple because it is less risky for the buyer.

The EBITDA multiple method strips out financing and accounting choices to focus on what the business actually earns from operations. Two businesses with the same revenue but different debt structures or depreciation schedules look identical under EBITDA — which is exactly why buyers prefer it. Most small business acquisitions are ultimately priced on this number.

The asset-based method asks what you would get if you sold everything and paid off all debts today. It sets a floor on the negotiation. Even if the business earns nothing, it might own land, equipment, or inventory with real value. This method matters most when earnings are minimal or the business is being liquidated rather than sold as a going concern.

Use this tool when you are exploring a potential sale, preparing for a capital raise, applying for a business acquisition loan, or benchmarking against peers before a partnership negotiation. It is also useful when buying a business — run the target's numbers through the same framework to see whether the asking price is in a plausible range for that industry.

This tool is appropriate for established businesses with at least one full year of revenue history and stable operations. It works best for main-street and lower-middle-market businesses with revenue between $250,000 and $10M. Below that range, buyers typically use simpler payback-period calculations. Above it, investment bankers run discounted cash flow models with sensitivity tables that this tool does not replicate.

Do not rely on this tool when the business is in significant financial distress, has highly lumpy or contract-driven revenue, operates in a regulated industry where license value dominates, or is being valued for a divorce or estate settlement. Those contexts require a formal certified appraisal with legal standing. A calculator result will not hold up in court or satisfy a lender requiring a written appraisal of record.

Mistake 1: Using personal expenses as business costs. Many small business owners run personal expenses through the company — car payments, phone bills, travel. These artificially deflate net profit, which deflates the EBITDA-based valuation. Before using this calculator, add back any personal expenses to get a cleaner profit figure. This process is called normalization or recasting, and a buyer's accountant will do it anyway during due diligence.

Mistake 2: Confusing revenue with value. A business with $2M in revenue is not automatically worth more than one with $800,000 in revenue. If the $2M business operates at a 3% margin and the $800,000 one operates at a 25% margin, the smaller business is almost certainly worth more. This calculator shows both revenue and EBITDA methods side by side so you can see which one actually drives your valuation.

Mistake 3: Ignoring owner salary normalization. If the owner pays themselves $40,000 when a market-rate manager would cost $120,000, the reported profit is overstated by $80,000. A buyer will immediately add back that $80,000 salary differential, reducing effective EBITDA and therefore the offer price. The tool cannot correct for this automatically — you need to enter normalized profit figures for an accurate result.

The blended estimate this calculator produces works as follows. Revenue value is computed as annual revenue multiplied by the industry revenue multiple. EBITDA value is computed as EBITDA multiplied by the industry EBITDA multiple. When both methods are available (positive profit), the midpoint of the two is taken. If total assets and liabilities are entered and equity is positive, the asset-based value is averaged in as a third data point.

Growth rate adjusts the multiple upward. Each percentage point of annual revenue growth adds approximately 2% to the applied multiple, capped at a 20% total lift. So a business growing at 15% per year gets roughly a 20% boost to its effective multiple compared to a flat-revenue peer. This reflects market behavior: buyers pay for trajectory, not just current earnings.

The valuation range is built from the low and high multiples in the same industry table. The low is the floor a distressed or declining business might fetch. The high reflects a well-documented, growing business with strong customer retention. Most businesses sell somewhere in the middle third of that range, adjusted for deal structure (cash vs. earnout), seller financing, and working capital treatment.

The multiple approach assumes that future cash flows are a stable multiple of current earnings — an assumption that breaks loudly in businesses with customer concentration above 30%, owner-dependent relationships, or expiring contracts. Sophisticated buyers will apply a discount to the multiple itself, not just the earnings figure, when these risks are present. A business where one client represents 40% of revenue might trade at 2.5x EBITDA in an industry where the standard is 4.5x. The calculator shows you the unrisked multiple; the negotiation discounts it.

A second assumption is that EBITDA is a good proxy for free cash flow. It is not, when the business requires heavy ongoing capital expenditure. A manufacturer with aging equipment may show $500,000 EBITDA but need $200,000 per year in capex just to maintain output — making true free cash flow $300,000. Buyers will apply the EBITDA multiple to the lower figure. If your business is capex-intensive, the right input is EBITDA minus normalized maintenance capex, not raw EBITDA.
