How to Value a Small Business: Methods and Worked Example
How to value a small business using SDE multiples, EBITDA, asset and cash flow methods, with a step-by-step worked example and the adjustments buyers make.
Here is how to value a small business in short: work out seller's discretionary earnings (SDE), the profit a full-time owner actually gets from the business, multiply it by a figure that reflects risk and growth, then cross-check the answer against asset value and expected cash flow. Finally, adjust for debt, cash and working capital to reach the amount the seller receives.
That is the method brokers, buyers and lenders use for most owner-run businesses with a few million dollars of revenue or less. This guide explains each step, compares the main business valuation methods, and walks through a full numerical example so you can estimate a realistic range for your own company before you speak to a broker or buyer.
Why the valuation method matters
A small business is worth what a buyer will pay for the future cash it produces, adjusted for the risk that the cash will not arrive. Different methods approach that idea from different angles:
- Earnings (market) methods apply a multiple to SDE or EBITDA, based on what similar businesses have sold for.
- Asset-based methods value what the business owns minus what it owes.
- Income methods estimate future cash flows and discount them back to today.
Most small business sales settle on an earnings multiple, but serious buyers check the others. If the three methods give wildly different answers, that is a signal to look harder at the numbers rather than pick the most flattering one.
Step 1: Get clean financial statements
Every valuation starts with reliable numbers. You need at least three years of profit and loss statements, a current balance sheet, and the tax returns that match them. Buyers will compare the two, and any gap between what the accounts say and what was declared for tax will either reduce the price or end the conversation.
Clean books also mean revenue that can be traced to real customers. Consistent, numbered invoices make that easy. If you issue invoices from scattered templates or handwritten pads, tidy that up well before a sale; an online invoice generator with sequential numbering gives you a clear trail, and the invoice number generator helps you set a consistent format. Separate personal spending from business spending now, because every personal expense you add back later is one more item a buyer has to take on trust.
Step 2: Calculate seller's discretionary earnings
SDE shows the total benefit a single owner-operator gets from the business. The formula is:
SDE = pre-tax net profit + owner's salary and benefits + interest + depreciation and amortization + one-off and discretionary expenses
Typical add-backs include:
- The owner's salary, payroll taxes on it, and health insurance or pension contributions paid by the business for the owner.
- Interest on business loans, because the buyer will arrange their own financing.
- Depreciation and amortization, which are non-cash accounting charges (see how depreciation is calculated).
- Genuinely one-off costs, such as a lawsuit settlement or a one-time office move.
- Personal expenses run through the business, such as a family member's phone or a personal vehicle, if you can document them.
Be strict. Buyers and their accountants will challenge every add-back, and an add-back you cannot prove usually gets removed, taking a multiple of its value off the price with it.
SDE vs EBITDA: which earnings figure to use
SDE and EBITDA look similar, but they suit different businesses. The table summarizes the difference.
| Feature | SDE | EBITDA |
|---|---|---|
| Owner's pay | Added back in full | Market-rate manager salary treated as a cost |
| Typical business | Owner-operated, one main owner working full time | Larger firms with a management team |
| Typical buyer | Individual who will run it | Investor, private equity or a competitor |
| Multiple applied | Usually lower | Usually higher, reflecting lower risk and larger size |
Applying an EBITDA-style multiple to SDE is a common seller mistake. It double counts the owner's salary and inflates the price beyond what any buyer will finance.
Step 3: Choose a realistic multiple
The multiple is a shorthand for risk and growth. A higher multiple means a buyer expects the earnings to be stable or growing; a lower one means they see more ways for the earnings to fall. Factors that push the multiple up or down include:
- Owner dependence: if customers buy from you personally, the business is worth less without you.
- Customer concentration: one customer providing a large share of revenue is a major risk.
- Recurring revenue: contracts, subscriptions and repeat customers raise value.
- Trend: three years of rising revenue and margins beat a flat or falling trend.
- Industry and size: larger businesses and sectors with steady demand attract higher multiples.
- Quality of records: clear books reduce perceived risk.
- Financing: many small deals depend on bank or SBA lending, and lenders will only fund a price the cash flow can support. The guide to SBA loans explains how those loans work in the United States.
Brokers often describe owner-operated businesses selling at a low single-digit multiple of SDE, but published averages are only a starting point. Comparable sales in your industry and region, usually gathered by a broker or professional valuer, are far more useful than any general rule of thumb.
Step 4: Cross-check with asset and cash flow methods
Asset-based value
Add up the fair market value of the assets, such as equipment, vehicles, inventory and receivables, then subtract liabilities. This gives a floor: a profitable business should be worth at least its net assets, and a loss-making one may be worth little more. For service businesses with few physical assets, the asset value will usually sit well below the earnings-based value.
Discounted cash flow
A discounted cash flow (DCF) estimate projects cash flow for several years, then discounts it at a rate that reflects risk. Small business discount rates are high because the risk is high, and small changes in the assumptions swing the answer widely. For most owner-run firms, DCF is a useful sanity check rather than the main method. If you already keep a cash flow forecast, you have most of the inputs.
A simple illustration: if a business is expected to produce $100,000 of free cash flow next year, growing 3% a year, and a buyer wants a 25% annual return for the risk, a basic perpetual growth formula gives $100,000 divided by (0.25 minus 0.03), or about $455,000. Raise the required return to 30% and the value drops to about $370,000. That sensitivity is exactly why buyers rely on several methods rather than one.
Rules of thumb
Some industries have informal rules of thumb, such as a percentage of annual revenue or a multiple of monthly recurring revenue. They can be a quick reasonableness check, but they ignore profit, so a business with weak margins will look far more valuable than it is. Use them only alongside an earnings-based figure.
Worked example: valuing a landscaping business
Here is how to value a small business with real numbers. The figures below are illustrative, including the multiple, and are not a guide to what any actual business is worth.
GreenLine Landscaping has one owner who works full time. Last year it reported revenue of $820,000 and pre-tax net profit of $96,000. The accounts also show:
- Owner's salary: $70,000, plus $9,000 of health insurance paid by the business
- Interest on an equipment loan: $6,000
- Depreciation: $24,000
- A one-off legal fee for a boundary dispute: $5,000
SDE calculation
| Item | Amount |
|---|---|
| Pre-tax net profit | $96,000 |
| Add owner's salary | $70,000 |
| Add owner's health insurance | $9,000 |
| Add interest | $6,000 |
| Add depreciation | $24,000 |
| Add one-off legal fee | $5,000 |
| SDE | $210,000 |
Applying a range of multiples
GreenLine has steady repeat contracts but relies heavily on the owner for sales, so a buyer is unlikely to pay a premium. Testing a range:
| Illustrative SDE multiple | Business value |
|---|---|
| 2.0x | $420,000 |
| 2.5x | $525,000 |
| 3.0x | $630,000 |
Cross-check against assets. The trucks, mowers and trailers have a fair market value of about $180,000. The earnings-based range is well above the asset floor, which makes sense for a profitable business.
Cross-check against debt service. Suppose a buyer pays $525,000, funds it with a loan costing about $75,000 a year in repayments, and needs a $70,000 salary to live on. That leaves $210,000 minus $75,000 minus $70,000, or $65,000 of cushion for equipment replacement, taxes and a bad year. A lender will look at this cushion closely. At $630,000, the loan repayments rise and the cushion shrinks, which is why the top of the range may be hard to finance.
From business value to seller proceeds. If the deal is cash-free and debt-free at $525,000, the owner pays off the $60,000 equipment loan and keeps the business cash. After broker fees and tax, the amount in the owner's pocket will be noticeably less than the headline price, so model it before agreeing terms.
How to value a small business: common mistakes
- Using revenue alone. Two businesses with the same revenue can have very different profits. Revenue multiples rarely apply to ordinary small firms; see revenue vs profit for why.
- Unprovable add-backs. Cash income that never reached the books and personal expenses with no receipts will not survive due diligence.
- Ignoring working capital. A buyer needs receivables, stock and cash to run the business from day one. If the deal does not leave enough working capital, expect a price adjustment.
- Picking the wrong multiple. Applying a multiple from a different industry or a much larger company gives a number no buyer will pay.
- Valuing hope. Buyers pay for proven earnings, not the growth you plan to achieve next year.
Preparing your business so it is worth more
The best time to think about how to value a small business is two or three years before a sale, because that is long enough to change the numbers buyers see. Practical steps:
- Keep monthly accounts closed on time and reconciled to the bank.
- Invoice promptly and chase overdue accounts, so receivables are current; days sales outstanding is a metric buyers check.
- Write down how the business runs and train someone else to handle sales and key customers.
- Put regular customers on written agreements and price increases on a schedule.
- Track gross margin by service line and drop work that does not pay.
A formal valuation from a qualified appraiser, accountant or business broker is worth paying for when the stakes are high, such as a sale, partner buyout, divorce, estate planning or a loan application. Tax on a business sale can be significant and depends on how the deal is structured, so check with a qualified adviser before signing.
Conclusion
Knowing how to value a small business comes down to three things: an honest earnings figure, a multiple that matches the risk, and cross-checks against assets and cash flow. Run the numbers yourself first, using the worked example above as a template, and you will negotiate from facts rather than hope.

Frequently asked questions
What is the most common way to value a small business?
For owner-operated businesses, the most common approach is a multiple of seller's discretionary earnings (SDE). You take net profit, add back the owner's salary and benefits, interest, depreciation, amortization and genuine one-off costs, then multiply by a figure that reflects risk and growth. Larger businesses with a management team are more often valued on a multiple of EBITDA. Buyers and brokers usually cross-check the result with an asset-based value and a cash flow method before agreeing a price.
What is seller's discretionary earnings (SDE)?
Seller's discretionary earnings is the total financial benefit a single full-time owner gets from the business in a year. It starts with pre-tax profit and adds back the owner's salary, owner benefits paid by the business, interest, depreciation, amortization and non-recurring or personal expenses. Because it includes the owner's pay, SDE shows what a new owner-operator could take home before paying for their own time, financing and taxes. It is the standard earnings measure for small business sales.
What multiple of SDE do small businesses sell for?
There is no fixed number. Brokers often describe small owner-operated businesses changing hands at a low single-digit multiple of SDE, but the right figure depends on industry, size, growth, how much the business relies on the owner, customer concentration, how clean the books are and current lending conditions. Treat any published multiple as a starting point only. Recent sales of similar businesses, ideally gathered by a broker or valuer, are the best guide for your situation.
Should I use SDE or EBITDA to value my business?
Use SDE if the business is run by one owner who works in it full time and would be replaced by a buyer who does the same. Use EBITDA if the business has a paid manager or management team and the buyer is more likely to be an investor than an operator. The key difference is that EBITDA treats a market-rate salary for the manager as a cost, while SDE adds the owner's pay back. Using the wrong one can distort the price.
How do you value a business with no profit?
If a business has little or no profit, an earnings multiple produces a very low number, so the floor is usually asset value: what the equipment, inventory and other assets would sell for, minus liabilities. Some buyers pay above that for strong revenue, customer lists, contracts or a brand, but they will want evidence that profit is achievable. Startups with high growth are sometimes valued on revenue multiples, but that is rare for ordinary small businesses and depends heavily on the buyer.
Does a business valuation include inventory and cash?
It depends on the deal. Many small business sales are priced on a cash-free, debt-free basis, so the seller keeps the cash and pays off debts. Inventory is often added on top of the agreed price at cost, or a normal level of working capital is included and the price is adjusted if the actual level at closing is higher or lower. Always confirm in writing what the headline price includes, because it can change the amount you actually receive by a large margin.
How much does a professional business valuation cost?
Costs vary with the size and complexity of the business and the purpose of the valuation. A broker's opinion of value is sometimes free if you list with them, while a formal written valuation from a credentialed appraiser, needed for some loans, tax filings, estate planning or legal disputes, costs considerably more. Ask for a fixed quote and the scope in advance. If a lender or tax authority is involved, check what type of valuation report they will accept before commissioning one.
How can I increase the value of my small business before selling?
Start with the items buyers discount for. Keep clean, consistent monthly books and separate personal spending from business spending. Reduce dependence on yourself by documenting processes and training staff. Spread revenue across more customers, put recurring work on written contracts, and collect receivables promptly so working capital looks healthy. Fix legal loose ends such as leases, licences and supplier agreements. These steps raise both the earnings figure and the multiple a buyer is willing to pay.
Is the asset-based method useful for service businesses?
Usually only as a floor. Service businesses such as agencies, consultancies or cleaning companies often own little equipment, so their asset value is far below what a buyer would pay for the earnings stream. The asset-based method is more relevant for asset-heavy businesses, such as manufacturing, transport or equipment hire, and for businesses that are losing money, where the realistic alternative to a sale is closing down and selling the assets individually.
