Business Valuation Calculator
This business valuation calculator estimates a planning range by multiplying normalized seller's discretionary earnings by an entered market multiple, then applying transparent adjustments for growth, owner dependence, and customer concentration. Use the result to frame research and conversations—not as an appraisal, guaranteed sale price, tax value, or lending decision.

Use these tools together to estimate financing, value, seller proceeds, and due diligence readiness before a serious buyer or seller conversation.
How the Business Valuation Calculator Works
Enter annual revenue for context, normalized seller's discretionary earnings (SDE), and a supportable industry multiple. The calculator multiplies SDE by the entered multiple, adjusts that multiple using the three selected risk factors, and displays a planning range 12% below and above the midpoint. Revenue is used only to show the implied revenue multiple; it does not independently increase the estimate.
The adjustment choices are intentionally transparent. Strong growth adds 8% to the multiple and low growth subtracts 8%. Low owner dependence adds 7% and high dependence subtracts 10%. Low customer concentration adds 6% and high concentration subtracts 9%. These are scenario assumptions built into this tool—not observed market premiums, appraiser conclusions, or predictions.
This calculator is for planning only and is not a formal appraisal, fairness opinion, tax valuation, legal opinion, lending approval, listing price recommendation, or guaranteed sale price. For more context, review what your business is worth before you sell, how to value a small business before buying, and active businesses for sale.
Prepare the Inputs Before You Calculate
- Reconcile earnings. Start with tax returns, profit-and-loss statements, bank activity, payroll, and supporting schedules.
- Normalize SDE. Include owner compensation and only documented, nonrecurring, discretionary, or replacement adjustments that a buyer can reasonably verify.
- Avoid double counting. If an item is already reflected in normalized SDE, do not add it again or adjust the multiple for the same benefit.
- Research the multiple. Use relevant industry, size, geography, margin, growth, and transaction evidence; an advertised asking multiple is not necessarily a completed-sale multiple.
- Assess transfer risk. Review customer and supplier concentration, owner responsibilities, employee depth, systems, contracts, licenses, leases, and required capital spending.
- Separate price from proceeds. Debt payoff, transaction costs, taxes, working-capital treatment, and payment structure can change what a seller ultimately receives.
Worked Valuation Example
Assume a business has $1,500,000 in annual revenue, $300,000 in normalized SDE, and a researched 3.2× SDE multiple. With all three risk selections set to Moderate, the midpoint is $960,000: $300,000 × 3.2. The calculator displays a planning range of about $844,800 to $1,075,200 and an implied revenue multiple of 0.64×.
If growth is Strong, owner dependence is Low, and customer concentration is Low, the combined adjustment is +21%. The adjusted multiple becomes 3.872× and the midpoint becomes $1,161,600. That change is a scenario comparison, not proof the market will pay the higher amount. Buyers, lenders, and appraisers may normalize earnings differently or use different methods and evidence.
Which Valuation Method Applies?
- Earnings or income approach: Relates value to normalized earnings, cash flow, growth, and risk. This calculator is a simplified earnings-multiple model.
- Market approach: Compares the company with sufficiently similar completed transactions or public-market evidence, with adjustments for important differences.
- Asset approach: Considers the value of assets less liabilities and may be especially relevant for asset-intensive, holding, or underperforming businesses.
- Deal-specific reconciliation: A conclusion may weigh more than one method and then consider working capital, assumed debt, excluded assets, real estate, payment terms, and other transaction terms.
The U.S. Small Business Administration's selling guidance identifies income, market, and asset approaches and recommends qualified professional advice. Its acquisition guidance likewise advises completing a valuation before agreeing to a sale.
When a Professional Valuation Is Needed
Seek qualified valuation, accounting, tax, legal, and transaction advice when the result will support an actual listing, offer, lender submission, partner buyout, shareholder dispute, estate or gift matter, divorce, litigation, employee ownership transaction, financial reporting decision, or tax filing. Those uses may require a specific standard of value, valuation date, scope, credential, method, documentation, and jurisdiction-specific treatment.
A buyer and seller can also agree on price while disagreeing about the allocation, financing, working capital, contingencies, representations, transition services, or payment risk. Model the transaction separately with the Seller Proceeds Calculator and obtain professional advice before relying on an estimate. Methodology reviewed: July 13, 2026.

Frequently Asked Questions
How accurate is a business valuation calculator?
A calculator is useful for planning, but it is not a formal valuation. Actual value depends on financial records, buyer demand, risk, deal terms, market conditions, and professional review.
What is SDE in business valuation?
Seller's Discretionary Earnings is an estimate of normalized owner benefit. It often starts with profit and adds back eligible owner compensation, discretionary expenses, one-time expenses, and supported adjustments.
What multiple should I use?
The right multiple depends on the industry, cash flow quality, growth, risk, customer concentration, owner dependence, and buyer demand. This calculator uses the multiple you enter for planning.
Does annual revenue determine the estimated value?
No. This calculator uses annual revenue only to display the implied revenue multiple. Its midpoint is based on normalized SDE multiplied by the adjusted SDE multiple. Revenue can still provide useful context when comparing margins and market evidence.
Are inventory, real estate, debt, and working capital included?
Not automatically. The estimate does not separately value inventory, real estate, excess cash, debt, or working-capital adjustments. Whether those items are included, excluded, or adjusted depends on the valuation scope and transaction terms.
Is estimated business value the same as seller proceeds?
No. Business value or transaction price is different from the seller's net proceeds after debt, fees, taxes, holdbacks, working-capital adjustments, and payment structure. Use the Seller Proceeds Calculator for a separate planning estimate.
