Small Business Valuation Calculator
Estimate small business value using SDE and EBITDA multiples by industry. BizBuySell benchmarks + adjustments for size, growth, owner dependence. Free.
Small Business Valuation Calculator
Estimates small business value as SDE × industry multiple, adjusted for growth rate, owner dependence, and revenue concentration. The industry bands are indicative ranges consistent with BizBuySell's reported market-wide average of about 2.6× cash flow; they are not published per-industry medians. Returns a low / mid / high range for ask-price strategy.
How to Use the Valuation Tool
Calculate SDE correctly
Seller's Discretionary Earnings = Net Income + Owner's Salary + Owner's Benefits + Interest + Depreciation + Amortization + One-Time Expenses. Add-backs require documentation — buyers + their advisors scrutinize them. Don't inflate SDE with personal-expense add-backs that won't survive due diligence.
Match industry honestly
The industry choice drives the base multiple. SaaS at 6× SDE is normal; restaurant at 6× is not. Misclassifying inflates estimates. If your business spans categories, use the dominant revenue source.
Be honest about qualitative factors
Owner dependence + customer concentration are the two biggest valuation killers buyers care about. A business where the owner is the sales relationship + only employee + technical know-how is valued at a steep discount to an identical-SDE business with a manager + diversified customers; in this tool that shows up as −0.5× for high owner dependence and −0.4× for high concentration.
Use the range strategically
List slightly above the mid value to leave negotiating room. Expect final sale at mid value minus 5-10% in typical SMB transactions. The "high" multiple usually requires a strategic buyer (competitor, PE platform) for whom your business has synergy value beyond the standalone SDE.
SDE Multiples — How Small Businesses Are Actually Priced
SDE vs EBITDA — Which Matters for Your Size
For businesses under USD 1M SDE: SDE (Seller's Discretionary Earnings) is the standard metric. SDE = Net Income + Owner's salary + Owner's benefits + Interest + Depreciation + Amortization + One-time expenses. It captures all the cash a single-owner business actually generates for the owner. Typical multiples: 2-4× SDE for most SMBs (industry-dependent).
For businesses USD 1M+ SDE or institutional-buyer markets: EBITDA (Earnings Before Interest, Tax, Depreciation, Amortization). EBITDA differs from SDE by NOT adding back owner compensation — assumes a market-rate manager replaces the owner. Typical multiples: 4-8× EBITDA for lower-middle-market. The transition from SDE to EBITDA happens around the USD 1-2M earnings range. Larger businesses sell at higher multiples per dollar of earnings — partly because they're more "buyable" by institutional buyers (PE firms, search funds, larger strategics) who price differently than owner-operator buyers.
The Qualitative Adjustments That Move the Multiple
Industry base multiples are starting points. Buyers adjust based on five qualitative factors. (1) Owner dependence: high (owner-driven sales, no SOPs, owner is technical lynchpin) drops multiple 0.5-1.0×. Low (manager runs day-to-day, owner is absentee) adds 0.3-0.5×. (2) Customer concentration: top 3 customers > 50% of revenue = "concentration risk" = drops multiple 0.3-0.5×. Diversified base (no customer > 10%) adds 0.2-0.3×. (3) Growth rate: 15%+ recurring growth adds 0.4-0.8×. Flat or declining: drops 0.5-1.0×. (4) Recurring revenue %: subscription/recurring vs one-time transactional. SaaS-style recurring gets premium multiple. (5) Documentation + processes: clean books, documented SOPs, transferable systems → premium. Messy records → discount or no sale.
BizBuySell's Insight Report for full-year 2024 (9,546 closed transactions) puts the market-wide average sale-price-to-cash-flow multiple at 2.57×, on a median sale price of USD 345,000. The per-industry bands in this tool — service 2.0–3.5×, restaurants 1.5–2.5×, e-commerce 2.5–4.5×, SaaS 4–10× — are indicative ranges built around that average, not published per-industry medians; treat them as a starting point and check your sector's comparables. The tool's "mid" multiple applies the qualitative adjustments to your inputs.
"BizBuySell Insight Report, full-year 2024: 9,546 small businesses changed hands at a median price of USD 345,000 and an average of 2.57× cash flow. The spread between low and high multiples is the qualitative factors — documented systems, recurring revenue and a manager who is not the owner are what move a business from one end of the band to the other."
What Makes a Business Truly "Saleable"
Many SMBs technically have value but aren't easily sellable. The "saleability" checklist: (1) clean financial statements (preferably reviewed by an outside CPA); (2) properly-tracked SDE add-backs that can survive Quality of Earnings review; (3) signed customer contracts not just handshake relationships; (4) employee handbook + documented SOPs; (5) tangible assets accounted-for; (6) clean lease assignable; (7) seller willing to provide 30-90 day transition support. Businesses without these sell at a discount to the calculator estimate — and many simply don't sell at all. Improving saleability over 6-12 months before listing is the highest-return work a seller can do.
Owner dependence is the single biggest discount on the price
SDE multiples for typical SMBs: 2-4×. SaaS 5-8×. Restaurants 1.5-2.5×.
EBITDA multiples kick in around USD 1M+ earnings: 4-8× for lower-middle-market.
BizBuySell Insight Report 2024: average sale at 2.57× cash flow, median price USD 345,000, across 9,546 closed deals.
Owner dependence is the #1 valuation killer — drops multiple 0.5-1.0×.
Customer concentration > 50% in top 3 drops multiple 0.3-0.5×.
Recurring revenue % commands premium — subscription SaaS gets highest multiples in SMB universe.
Quality of Earnings (QoE) review: an independent accountant's test of the add-backs behind SDE, routinely commissioned by buyers of larger businesses.
IRS Revenue Ruling 59-60 is the classic statement of the factors that value a closely held business — earnings capacity, industry outlook, goodwill and comparables.
Business broker fees are a percentage of the sale price, commonly around a tenth on Main Street deals and a smaller share on larger ones — negotiate them.
SBA 7(a) financing is the dominant funding source for SMB acquisitions under USD 5M.
Frequently Asked Questions
- Seller's Discretionary Earnings = Net Income + Owner's Salary + Owner's Benefits + Interest + Depreciation + Amortization + Non-recurring expenses. Captures all the cash a single-owner business generates for the owner. The standard valuation metric for SMBs under USD 1M earnings. Above that, switch to EBITDA which doesn't add back owner compensation.
- Industry-dependent. Service: 2-3×. Restaurant: 1.5-2.5×. E-commerce: 3-4×. SaaS: 5-8×. Manufacturing: 2.5-4×. Healthcare: 3-5×. Within an industry, multiples vary by growth, owner dependence, concentration. The tool's "mid" multiple uses your inputs to land within the industry range.
- Top moves: (1) reduce owner dependence — hire a manager, document SOPs, systematize customer relationships. Worth 0.3-0.8× extra. (2) Diversify customers — no client should exceed 15% of revenue. Worth 0.2-0.5×. (3) Grow profitably — 15%+ recurring growth adds 0.4-0.8×. (4) Convert to recurring revenue model where possible — premium multiples. (5) Clean up books — buyers heavily discount messy financials. 6-12 months of focused work can add 30-50% to sale price.
- Typical SMB sale: 6-12 months from listing to close. Pre-listing prep (clean financials, prepare CIM): 1-3 months. Marketing + buyer screening: 2-4 months. Letter of intent + due diligence: 1-3 months. Closing: 30-60 days. Plan for 12-18 months total from "decide to sell" to "cash in hand". Smaller businesses (under USD 500K SDE) often take longer due to fewer buyers.
- For businesses USD 200K+ SDE: usually yes, even at a commission of around a tenth of the price. Brokers provide marketing reach (proprietary buyer lists), confidentiality, negotiation, deal-structuring expertise. For smaller businesses (under USD 200K SDE): often more cost-effective to list on BizBuySell yourself + negotiate directly. For larger businesses (USD 5M+): consider M&A advisor instead of business broker — different skill set, lower percentage fee on larger absolute deal.
- Independent CPA review of seller's reported earnings + add-backs. Standard for buyer due diligence on businesses USD 500K+ SDE. Verifies that add-backs are legitimate (truly one-time or owner-discretionary) and identifies any "reversed" working capital changes that overstate earnings. QoE is buyer-funded and priced by the accountant's hours. Sellers can do a "sell-side QoE" preemptively to identify and fix issues before buyer review — material to deal certainty.
- For US SMB sales, asset sales dominate. Buyer gets stepped-up basis for depreciation; seller faces double taxation (corporate gain + dividend if C-corp; flow-through if S-corp or LLC). Stock sales preferred by sellers for cleaner tax treatment but harder to negotiate — buyer assumes all known + unknown liabilities. C-corp sellers often forced to asset sale by buyer demand; pass-through entities have more flexibility.
- Common. SBA 7(a) buyers often require 10-20% seller note as part of the deal structure. Cash-only deals exist but typically price below a seller-financed equivalent. Seller notes usually amortise over several years at a negotiated rate and stand behind the SBA lender. Many sellers accept partial seller financing to maximize price + provide buyer with skin-in-the-game alignment. Get a personal guarantee from buyer on any seller note.
- A contingent portion of the purchase price tied to future performance (typically next 1-3 years of revenue or EBITDA). Used when buyer + seller disagree on price — seller bets on future, buyer pays only if it materializes. Earnouts are commonly a minority slice of the total deal value. Bias: earnouts favor buyer (control of business affects payout) — sellers prefer to take cash even at a discount. Most negotiated when projections look aggressive but seller believes them strongly.
- A large share of listed small businesses never close. Reasons for failure: priced too high (most common), owner-dependent (no transferable systems), high customer concentration, poor financial records, geographic + industry mismatches with buyer pool. Improving saleability factors before listing (clean books, documented SOPs, manager-led, diversified customers, recurring revenue %) dramatically improves close probability. Pre-list with a broker who can assess saleability honestly.

How it computes
Value = SDE × multiple + tangible assets, with low/mid/high multiples from a per-industry band; the mid multiple is adjusted for revenue growth (−0.5 to +0.4), owner dependence (−0.5 / +0.3), customer concentration (−0.4 / +0.2) and years in business (−0.3 / +0.2). Bands are indicative, calibrated around BizBuySell's 2024 market-wide average of 2.57× cash flow.
What this tool implements
- Seller's Discretionary Earnings = net income + owner salary and benefits + interest + depreciation + amortisation + non-recurring items (IBBA/BizBuySell usage); EBITDA discussed for larger businesses
- Market (multiples) approach only — no income (DCF) or asset approach beyond adding tangible assets at book
- Per-industry bands are the tool's own indicative ranges, disclosed as such — not published medians
