How to Value a Small Business: SDE, Assets and Market

Small businesses are usually valued with a multiple of seller's discretionary earnings (SDE), the cash profit available to one full-time owner-operator, cross-checked against the asset approach and comparable sale data. The appropriate multiple depends on size, transferability, customer concentration and owner dependence. Lenders then test whether cash flow after a market-rate manager supports the debt.

How are small businesses valued differently from larger companies?

Small owner-operated businesses differ from middle-market companies in ways that change the valuation method. Financial statements are often prepared for tax purposes rather than for investors, the owner frequently performs several roles that would otherwise be paid employees, and personal and business expenses may be mixed. Buyers are typically individuals who will run the business themselves, often financed with government-guaranteed loans and seller notes. As a result, value is anchored to the cash a single owner can take from the business rather than to an institutional measure like EBITDA after full management costs. Liquidity is also thinner, so pricing is less precise and depends more on the individual deal.

The three standard approaches still apply: income, market and asset. In practice the income approach for small businesses is usually expressed as a multiple of seller's discretionary earnings rather than a full DCF, because forecasts are unreliable and buyers think in terms of payback. The market approach draws on databases of private business sales, and the asset approach sets a floor based on what the tangible assets would bring. A credible valuation reconciles all three and explains why one is weighted more heavily than the others for the particular business being valued.

What is seller's discretionary earnings (SDE)?

Seller's discretionary earnings is the total pre-tax cash benefit available to one full-time owner-operator before debt service. It starts with net income and adds back the owner's salary and payroll taxes, the owner's personal benefits paid by the business, interest, depreciation and amortization, and nonrecurring or non-operating items. The idea is to show what a new owner who works in the business would have available to pay themselves, fund capital expenditures and service acquisition debt. SDE is therefore larger than EBITDA, because EBITDA deducts a market-rate salary for management.

Every add-back should be supported. Owner compensation should be verified through payroll records. Personal expenses such as vehicles, travel or family members on payroll should be documented and confirmed as not necessary to run the business. Only one owner's compensation is normally added back; if two partners both work full time, the buyer will need to replace at least one of them. One-time items should be genuinely nonrecurring, not costs that happen to vary from year to year. Discipline here matters because each dollar of overstated SDE is multiplied into the purchase price.

How are SDE multiples chosen?

SDE multiples for small businesses typically fall in a narrower and lower range than EBITDA multiples for larger companies, reflecting higher risk and the fact that the buyer is purchasing a job as well as an investment. Within that range, the multiple depends on factors that affect the durability and transferability of earnings: length of operating history, consistency of results, customer concentration, dependence on the owner's personal relationships or licenses, quality of staff, lease terms, and growth trend. Industry matters as well, because some sectors have more predictable revenue or more buyer demand.

Private transaction databases provide observed multiples of SDE and revenue for sold businesses, segmented by industry and size. These figures are useful but noisy: definitions of SDE vary by preparer, deal terms such as seller financing and earnouts affect headline prices, and sample sizes can be small. The analyst should use the data to frame a range and then position the subject within it based on documented strengths and weaknesses, rather than applying a single industry average without adjustment. A list of positive and negative factors with their direction of effect makes that reasoning transparent.

• Higher multiple: long history, recurring revenue, diversified customers, trained staff, documented processes
• Lower multiple: owner-dependent sales, licenses held personally, short lease, declining revenue, concentration

When does the asset approach matter?

The asset approach values a business as the fair value of its assets less its liabilities. For a profitable going concern it usually produces a lower figure than the income approach because it ignores goodwill, the value of the business's ability to earn returns above those on its tangible assets. It becomes central in three situations: when earnings are weak or negative so that an earnings multiple produces little value, when the business is asset intensive, such as equipment-heavy contractors or real estate holding companies, and when assessing collateral and recovery for a lender.

Fair value of assets differs from book value. Equipment may be fully depreciated yet still productive, inventory may include obsolete items, and receivables may contain uncollectible balances. Appraisals or orderly liquidation estimates are used for significant fixed assets. For lenders, the asset approach informs how much of a loan is supported by hard collateral and how much relies on goodwill, which typically has little recovery value in a liquidation. A purchase price far above tangible net assets means the lender is effectively underwriting the continuation of cash flow.

How do lenders test a small business purchase price?

Lenders start from SDE but then deduct a market-rate salary for the new owner or a hired manager, normal capital expenditures and any new costs the buyer will bear, such as higher rent under a new lease. The result approximates the cash available for debt service. Debt service coverage is then calculated on the proposed acquisition loan, any seller note and the buyer's personal obligations, depending on the program. Coverage below the required threshold signals that the price is too high for the financing structure, regardless of what industry multiples suggest.

Lenders also consider the buyer's experience, the transition period agreed with the seller, and whether a seller note is subordinated and on standby. Tax returns are typically required and should reconcile to the financial statements used to compute SDE. Where they diverge, lenders generally rely on the tax return figures unless the difference is clearly explained. Customer concentration and key-person risk are evaluated qualitatively, and mitigation such as a seller earnout or consulting agreement may be required. The lender's question is ultimately whether the business can service the debt after the seller leaves.

How should the three approaches be reconciled?

A valuation report should present the income, market and asset results side by side and explain the weighting. For a stable service business with little tangible capital, the SDE multiple and market data usually dominate, with the asset approach serving as a floor. For an asset-heavy business with modest earnings, the asset approach may carry most of the weight. Large gaps between methods should be investigated rather than averaged away, because they often reveal inflated add-backs, an unrealistic multiple or assets carried at stale values.

The conclusion should also address deal terms. Seller financing, earnouts, working capital targets and whether the sale is of assets or stock all affect what the buyer actually pays and receives. An asset sale typically excludes cash and debt and gives the buyer a tax basis step-up, while a stock sale transfers all liabilities. Price and terms are linked: a higher headline price with a large earnout may be economically similar to a lower price paid entirely at closing, and the valuation should make that relationship visible to the parties.

SDE-based valuation cross-checked with an EBITDA view

1. Reported net income = $180,000. Add owner salary $120,000, interest $15,000, depreciation $35,000, one-time legal settlement $20,000 and personal vehicle costs $10,000.
2. SDE = 180,000 + 120,000 + 15,000 + 35,000 + 20,000 + 10,000 = $380,000.
3. Selected SDE multiple of 2.8x: indicated value = 2.8 x 380,000 = $1,064,000.
4. EBITDA view: deduct a market-rate general manager salary of $95,000. EBITDA = 380,000 - 95,000 = $285,000. At 3.7x EBITDA, value = 3.7 x 285,000 = $1,054,500, consistent with the SDE result.
5. Asset approach: fair value of tangible assets less liabilities = $450,000, so roughly $614,000 of the SDE-based price represents goodwill.
6. Lender check: available cash flow after manager salary and $40,000 of normal capex = 285,000 - 40,000 = $245,000. Against annual debt service of $165,000, coverage = 245,000 / 165,000 = 1.48x.

How underwriters apply this

• Verify every SDE add-back with source documents and add back only one owner's compensation unless the buyer can genuinely eliminate a second role.
• Convert SDE to cash available for debt service by deducting a market-rate manager salary and normal capex before testing coverage.
• Use the asset approach to measure how much of the loan relies on goodwill and size collateral expectations accordingly.
• Reconcile the valuation financials to filed tax returns and investigate any unexplained gap.
• Evaluate owner dependence and transition terms; consider seller notes on standby or earnouts to bridge transfer risk.
