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 typically valued at 60-70% of what an identical SDE business with a manager + diversified customers would fetch.

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 quarterly reports show typical SMB sale multiples cluster around 2.3-2.8× SDE for service businesses, 1.8-2.4× for restaurants, 3.0-4.0× for established e-commerce, 5-8× for SaaS. Outliers in either direction reflect the qualitative factors. The tool's "mid" multiple incorporates these adjustments based on your inputs.

"BizBuySell 2024 SMB Marketplace Report: median small business sells at 2.4× SDE. 75th percentile 3.1×. The spread between low + high reflects the qualitative factors: well-run businesses with documented systems + recurring revenue + manager-led sell at 30-50% premium to comparable size + industry."

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 typically sell for 30-50% less than the calculator estimate — and many simply don't sell at all. Improving saleability over 6-12 months before listing can double the actual realized price.

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: yes, typically worth the 10-15% commission. 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 typically costs USD 15-50K and is buyer-funded. 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 (80%+ of transactions). 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 15-25% below seller-financed equivalent. Seller financing terms: typically 5-10 year amortization, 5-8% interest, second-position to SBA. 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. Common 10-30% of total deal value in earnouts. 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.
  • Statistics show only ~20% of listed SMBs successfully 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.
