How Much Does It Cost to Buy a Business?
The cost to buy an existing small-to-medium business typically ranges from $50,000 for a micro-turnkey service company or route up to $5,000,000+ for an established manufacturing, distribution, or healthcare enterprise. Most mainstream small businesses are valued and sold based on an earnings multiple—specifically 2.0x to 4.5x Seller Discretionary Earnings (SDE) or 4.0x to 7.0x EBITDA for larger mid-market firms. Beyond the headline purchase price, buyers must budget an additional 5% to 15% for mandatory transaction costs, including CPA financial due diligence, legal counsel, SBA loan guarantee fees, and initial working capital reserves.
Valuation Methodologies: SDE vs EBITDA Multiples
Small business valuations are predominantly determined by cash flow rather than physical hard assets. For businesses generating under $1,000,000 in owner benefit, the standard valuation benchmark is Seller Discretionary Earnings (SDE). SDE represents the total financial benefit a single full-time owner-operator derives from the business, calculating net pre-tax profit and adding back owner salary, personal discretionary expenses, depreciation, interest, and non-recurring one-time costs.
Most profitable small businesses sell for an SDE multiple between 2.2x and 3.8x. For instance, a commercial plumbing contracting business generating $250,000 in annual SDE standardly commands a purchase price between $550,000 and $950,000. Larger mid-market companies (generating over $1,500,000 in earnings with semi-absentee management structures) transition to EBITDA valuation multiples (Earnings Before Interest, Taxes, Depreciation, and Amortization), trading at 4.5x to 8.0x depending on recurring contracts and industry growth rates.
Compare average purchase prices, valuation multiples, and annual cash flows across common business categories:
| Business Industry / Type | Typical Valuation Multiple | Average Purchase Price Range | Typical Owner Cash Flow (SDE) |
|---|---|---|---|
| Service Route (Lawn / Pool / Vending) | 1.5x to 2.5x SDE | $75,000 to $225,000 | $45,000 to $95,000 SDE |
| Independent Auto Repair Facility | 2.2x to 3.2x SDE | $350,000 to $850,000 | $140,000 to $280,000 SDE |
| Commercial HVAC / Plumbing Contractor | 2.8x to 4.2x SDE | $650,000 to $2,200,000 | $220,000 to $550,000 SDE |
| B2B Software / SaaS Enterprise | 4.5x to 8.5x ARR/EBITDA | $1,500,000 to $8,000,000+ | $350,000 to $1,200,000 EBITDA |
| Established Medical / Dental Practice | 0.7x to 0.9x Gross Revenue | $500,000 to $1,400,000 | $180,000 to $400,000 SDE |
| Turnkey Franchise Resale (Fast Casual) | 2.5x to 3.8x SDE | $400,000 to $1,500,000 | $150,000 to $400,000 SDE |
SBA 7(a) Loans, Seller Financing, and Equity Down Payments
Buyers rarely pay 100% cash when acquiring an existing business. The most popular financing vehicle in the United States is the Small Business Administration (SBA) 7(a) loan program. SBA 7(a) loans allow qualified buyers to finance up to $5,000,000 with a standard 10% to 20% equity cash down payment, amortized over a favorable 10-year term at prime-plus interest rates. Securing an SBA loan requires strong credit (typically 680+), transferable managerial experience, and two to three years of verified company tax returns demonstrating healthy debt-service coverage (DSCR > 1.25).
Seller financing represents another critical funding mechanism in small business mergers and acquisitions. Sellers frequently agree to finance 10% to 30% of the total purchase price through a subordinated promissory note carrying 6% to 9% interest over three to seven years. Seller financing demonstrates seller confidence in future operational viability, bridges valuation gaps, and can often be counted toward a buyer required equity injection by SBA commercial lenders.
Review a financing and transaction cost capital stack for acquiring an $800,000 small business:
| Capital Stack Component | Percentage of Total | Dollar Amount ($800k Buy) | Funding Source / Terms |
|---|---|---|---|
| Buyer Cash Equity Injection | 10.0% | $80,000 | Personal liquid capital or HELOC savings |
| SBA 7(a) Commercial Bank Loan | 75.0% | $600,000 | 10-year term, Prime + 2.75% variable interest rate |
| Seller Subordinated Note | 15.0% | $120,000 | 5-year term, 7.5% interest, on full standby for 2 yrs |
| CPA Quality of Earnings (QofE) Audit | 1.5% | $12,000 | Professional forensic tax and revenue audit |
| M&A Legal Counsel (Asset Agreement) | 1.2% | $9,500 | Drafts Asset Purchase Agreement (APA) & closing docs |
| Working Capital Operating Reserve | 6.2% | $50,000 | Post-closing payroll and inventory buffer |
Transaction Fees, Quality of Earnings, and Working Capital
Acquiring a business requires absorbing substantial professional transaction expenses before taking ownership keys. The most vital due diligence expenditure is commissioning a Quality of Earnings (QofE) review or proof-of-cash audit from an independent CPA firm ($8,000 to $20,000). A forensic QofE verifies bank deposits against IRS tax filings, confirms genuine supplier costs, audits inventory levels, and ensures stated SDE add-backs represent legitimate, defensible adjustments.
Retaining an experienced mergers and acquisitions (M&A) attorney is equally critical to draft the definitive Asset Purchase Agreement (APA), negotiate non-compete covenants, structure indemnification escrow holdbacks, and perform UCC lien searches ($7,500 to $18,000). Finally, buyers must ensure the acquisition package includes adequate net working capital (NWC) or secure a revolving line of credit to finance accounts receivable and maintain payroll during operational transitions.
