There are three core business valuation methods: the asset-based approach (what the company owns minus what it owes), the income approach (what the future cash flow is worth today, via discounted cash flow or an earnings/SDE multiple), and the market approach (what comparable businesses actually sold for). Most small US businesses are valued with the income approach — specifically a multiple of Seller's Discretionary Earnings (SDE) — because for an owner-operated company, the value lives in the cash the business throws off, not in its furniture. The right method depends on why you're valuing: a sale, a partner buyout, estate planning, or raising capital. This guide walks through each method from an underwriter's chair, shows worked examples, and explains where valuation and financing actually meet.
Key takeaways
- The three core valuation methods are asset-based, income (DCF or an SDE/EBITDA multiple), and market comparables.
- Most small owner-operated US businesses are valued on a multiple of Seller's Discretionary Earnings (SDE), not on their assets.
- SDE adds the owner's salary and perks back to profit; EBITDA does not — SDE fits businesses under roughly $1M in earnings, EBITDA above that.
- The earnings multiple rises with clean books, recurring revenue, and low owner-dependence, and falls with customer concentration or declining sales.
- Owner-dependence and customer concentration are the two issues that most often compress a small-business valuation.
- Asset-based value is best treated as a floor; income and market approaches usually set the actual price for a profitable business.
- For working capital without a formal valuation, revenue-based/MCA marketplace funders approve on bank deposits and revenue — from about $10,000, FICO 500+, decisions in 24–48 hours (never guaranteed).
The three valuation approaches at a glance
Every credible valuation method rolls up into one of three families. Appraisers often run more than one and reconcile the results, but on a small owner-operated business, one approach usually leads and the others sanity-check it.
- Asset-based approach. Value equals assets minus liabilities. In its simplest form that's book value from the balance sheet; a better version is adjusted net asset value, where you re-price assets to what they'd fetch today. Best for asset-heavy or holding companies, and for a floor value in a liquidation scenario.
- Income approach. Value equals the present worth of expected future earnings. Two common engines: a discounted cash flow (DCF) that projects and discounts free cash flow, and an earnings multiple applied to SDE or EBITDA. This is the workhorse for profitable, cash-generating small businesses.
- Market approach. Value is inferred from what similar businesses sold for — expressed as a multiple of revenue, SDE, or EBITDA drawn from comparable transactions. Best when there's a deep pool of recent comps in the same industry and size band.
A clean valuation is really a story about cash flow durability: how much the business earns, how reliably, and how much of that survives an ownership change. That same question is what a revenue-based lender asks — which is why the numbers you assemble for a valuation double as the numbers that get you funded.
Asset-based valuation: floor value and asset-heavy cases
The asset-based approach answers a narrow question: if you netted everything the business owns against everything it owes, what's left for the owner? Start with the balance sheet, then adjust each line to real-world value — mark inventory to what it would actually sell for, write receivables down for what won't collect, re-price equipment to used-market value, and pull any personal or non-operating assets out.
Where it fits:
- Asset-heavy operations — trucking, manufacturing, construction, real-estate holding companies — where the equipment and property are the business.
- Businesses with thin or negative earnings, where an income multiple would understate the tangible worth.
- Liquidation or distress scenarios, where you need an orderly or forced-sale floor.
Where it misleads: a profitable service business — a marketing agency, a home-services company, a medical practice — usually earns far more than its assets are worth. Value that on assets alone and you leave most of the price on the table, because you've ignored goodwill, the customer base, and the earnings power. That gap between adjusted asset value and income value is exactly the intangible value the other two methods capture.
Income approach: SDE, EBITDA, and discounted cash flow
For most Main Street businesses, the income approach is the main event, and Seller's Discretionary Earnings (SDE) is the starting number. SDE is what an owner-operator truly earns from the business: net profit, plus the owner's salary and perks, plus interest, taxes, depreciation and amortization, plus one-time or non-recurring costs added back. It normalizes the business to a single owner-benefit figure so buyers can compare apples to apples.
On larger or manager-run businesses you'll see EBITDA (earnings before interest, taxes, depreciation, and amortization) used instead — the difference is that EBITDA does not add back an owner's salary, because a bigger business pays real management. As a rough rule of thumb: SDE for businesses under roughly \$1M in earnings, EBITDA above that.
You then apply a multiple. A business earning \$200,000 in SDE at a 2.5x multiple points to a value around \$500,000. The multiple isn't arbitrary — it rises with clean books, recurring revenue, low owner-dependence, growth, and diversified customers, and it falls with concentration risk, declining sales, or an owner who is the business.
Discounted cash flow is the more rigorous income method: project free cash flow for five or more years, discount each year back to present value using a rate that reflects the risk, add a terminal value, and sum it. DCF is powerful for businesses with predictable, growing cash flow, but it's sensitive — small changes to the growth or discount assumptions swing the answer a lot. For most small deals, an SDE multiple is what actually closes; DCF is the check on it.
Market approach: pricing off real comparable sales
The market approach values a business the way a realtor prices a house — by what comparable ones actually sold for. Analysts pull closed small-business transactions in the same industry, size, and geography, express each sale as a multiple (price ÷ SDE, price ÷ EBITDA, or price ÷ revenue), and apply the range to your business.
Revenue multiples are a quick screen but a blunt one: two businesses with identical revenue can be worth very different amounts if one keeps 25 cents of every dollar and the other keeps 6. SDE and EBITDA multiples are far more honest because they price the earnings, not the top line. Comps work best where deal data is deep — restaurants, e-commerce, HVAC, salons, laundromats — and get shaky in niche industries where few comparable sales exist. Treat the multiple as a market-tested reality check on your income-approach number, not a substitute for understanding your own cash flow.
Worked example: three methods, one business
Consider a hypothetical home-services company — call it a regional HVAC and plumbing shop with \$1.2M in annual revenue, a fleet of vans, and one working owner. The table shows how each method lands. All figures are illustrative, for example only.
| Method | Key inputs (for example) | Indicated value | What it captures |
|---|---|---|---|
| Asset-based (adjusted) | Vans, tools, inventory re-priced to used value, minus debt | ~\$260,000 | Tangible floor only; ignores earnings power |
| Income — SDE multiple | SDE of \$240,000 × 2.75x | ~\$660,000 | Owner-benefit cash flow and its durability |
| Income — DCF | Projected free cash flow, discounted for risk + growth | ~\$690,000 | Forward-looking, assumption-sensitive |
| Market comps | Similar HVAC sales at 2.5x–3.0x SDE | ~\$600,000–\$720,000 | What buyers actually paid recently |
Notice the pattern: the asset value is a floor, and the three earnings-based views cluster in the \$600K–\$720K range. A reconciled valuation would weight the income and market approaches heavily and treat the asset number as a downside anchor. The takeaway for any owner: your business is worth its cash flow, and the fastest way to raise the number is to raise clean, provable, transferable earnings.
Decision framework: which method fits your situation
Pick the lead method by matching the business to the approach, then use a second method to confirm.
Asset-based works best when:
- The business is asset-heavy (equipment, vehicles, real estate, inventory).
- Earnings are thin, erratic, or negative.
- You need a liquidation or floor value.
Income approach (SDE/EBITDA multiple or DCF) works best when:
- The business is profitable and the value is in its cash flow, not its stuff.
- Books are clean enough to defend the add-backs.
- Earnings are reasonably stable or growing (DCF especially rewards predictability).
Market approach works best when:
- There's a deep pool of recent comparable sales in your industry and size.
- You want a market-tested sanity check on your income number.
Avoid leaning on a single method when: the business is owner-dependent (one person is the reason customers stay), revenue is concentrated in a few clients, the books are messy or commingled with personal spending, or the industry has almost no comparable sales. In those cases, run at least two approaches and reconcile — and expect the multiple to compress until the risk is fixed. Owner-dependence and customer concentration are the two issues that quietly cost small businesses the most valuation.
Where valuation meets financing
Business owners run a valuation for four common reasons: selling, buying out a partner, estate or divorce planning, or raising money. The mechanics diverge sharply on that last one. A business acquisition or SBA loan leans on the valuation itself — the appraised value and projected cash flow support the debt. But when an existing owner needs working capital to grow, cover a gap, or fund a specific push, the question shifts from "what's the whole company worth" to "what does the cash flow support right now."
That's the lane where a revenue-based / MCA marketplace fits. Instead of underwriting a formal valuation, credit report, or collateral, these funders approve on bank deposits and revenue — the same cash-flow durability a valuation measures, read straight off recent statements. Typical parameters in this market: funding from around \$10,000, personal FICO 500+ accepted, decisions in 24–48 hours, and repayment scaled to your deposit volume rather than a fixed valuation-based term. Approval is never guaranteed, and pricing reflects risk — but for an owner who wants capital without the time, cost, and equity-dilution of a full valuation-and-loan process, it's often the faster path.

Frequently asked questions
What is the most common way to value a small business?
A multiple of Seller's Discretionary Earnings (SDE). You calculate SDE — net profit plus the owner's salary and perks, interest, taxes, depreciation, amortization, and one-time costs — then apply a market multiple, often in the range of about 2x to 3.5x for Main Street businesses. It's popular because, for an owner-operated company, the value is in the cash flow, and SDE normalizes that into one comparable number.
What's the difference between SDE and EBITDA?
Both are normalized earnings, but SDE adds back one working owner's salary and benefits while EBITDA does not. SDE answers "what does an owner-operator take home," which fits smaller businesses where the owner runs the shop. EBITDA answers "what does the business earn after paying real management," which fits larger, manager-run companies. As a rough line, use SDE under about $1M in earnings and EBITDA above it.
Which valuation method gives the highest value?
It depends on the business, but for a profitable service company the income and market approaches almost always come in above the asset-based approach, because assets ignore goodwill and earnings power. For an asset-heavy business with thin profits, the asset-based approach can be the highest. There's no universally 'highest' method — the right one is the one that matches how the business actually creates value.
How do I increase my business's valuation?
Raise clean, provable, transferable cash flow. Practically: keep the books clean and separate from personal spending, build recurring or contracted revenue, reduce dependence on any single customer, and reduce dependence on you personally by documenting systems and training a team. Each of those lifts the earnings multiple a buyer or appraiser will apply, often more than a bump in raw revenue does.
Do I need a formal valuation to get business funding?
Not always. Acquisition loans and SBA financing typically require a formal valuation because the deal is underwritten on the value of the company. But for working capital, revenue-based and MCA marketplace funders skip the formal valuation entirely and approve on your bank deposits and revenue — the same cash flow a valuation measures, read directly from recent statements. That's usually faster, though approval and pricing depend on your numbers and are never guaranteed.
How long does a business valuation take?
A formal, defensible valuation from an appraiser typically takes a few weeks and involves reviewing several years of financials, tax returns, and comparable sales. A quick internal estimate using an SDE multiple can be done in an afternoon once your add-backs are clean. If your goal is capital rather than a defensible number for a sale, a revenue-based funder can often decide in 24–48 hours on bank statements alone.
What is discounted cash flow (DCF) and when should I use it?
DCF projects a business's future free cash flow, then discounts each year back to today's value using a rate that reflects the risk, and adds a terminal value. Use it when cash flow is predictable and growing — it captures forward value that a single-year multiple misses. Its weakness is sensitivity: small changes to the growth or discount assumptions move the answer a lot, so for small deals it's best used as a check on an SDE multiple rather than the sole method.
Can I value a business that isn't profitable yet?
Yes, but the method changes. A pre-profit business is usually valued on its adjusted net assets (a floor), on revenue multiples from comparable sales, or on a forward-looking DCF if there's a credible path to positive cash flow. Expect a wider range and more skepticism from buyers and lenders, because without durable earnings the risk — and therefore the discount — is higher.
