You look up what your business is worth, find a calculator, and it tells you your company with $900,000 in revenue is worth $1.8 million. A month later, a real buyer offers $650,000.
Both numbers came from a multiple. Only one of them came from your actual financials, your risk profile, and what a buyer will finance.
Valuing a small business for sale is less about a formula and more about proving the profit a new owner can count on. Get that wrong, and you either scare off buyers with a fantasy number or leave real funds on the table with a timid one.
As a Toronto CPA advisory firm that values and sells founder-led businesses across Canada and the US, we see both mistakes often, and the gap between them is usually a proper valuation done too late.
Below, we cover what buyers actually pay for, the three ways to value a business, what moves your multiple, and the tax that decides what you keep. Here is what to expect.
TL;DR — Valuing a Small Business for Sale
- A small business is valued from its maintainable earnings rather than its revenue, and buyers pay a multiple of that profit.
- Owner-operated businesses are usually valued on Seller’s Discretionary Earnings (SDE), while larger ones use EBITDA.
- Professionals use three approaches, income, market, and asset, and cross-check one against another.
- Rule-of-thumb multiples are a rough starting point, and US figures can mislead in the Canadian market.
- Your multiple rises with recurring revenue, a diversified customer base, and low owner-dependency, and it falls with concentration and risk.
- The valuation that matters for a sale is the after-tax one, because a qualifying share sale can access the LCGE.
- A professional, defensible valuation holds up far better than a calculator when a real buyer is on the other side.
A number you cannot defend is a number a buyer will talk down.

What Buyers Actually Pay For
A buyer is not paying for last year’s sales. They are paying for the profit the business can reliably produce for its next owner.
That figure is maintainable earnings, the normalized profit a new owner could expect after adjusting for one-time items and a market-rate wage for the work the owner personally does. Revenue tells a buyer the size of the business, while maintainable earnings tell them what it is worth.
For most owner-operated small businesses, that profit is measured as Seller’s Discretionary Earnings (SDE): pre-tax profit with the owner’s salary, benefits, and discretionary or one-time expenses added back. SDE answers a simple question, which is how much the business puts in a single working owner’s pocket.
Larger businesses are measured on EBITDA, earnings before interest, taxes, depreciation, and amortization, because they run on a management team rather than one owner. The line between the two is roughly where the business can pay a full management wage and still show a strong profit.
Normalization is where value is found or lost. A buyer will add back a one-time legal bill or an above-market salary you pay yourself, and will strip out a below-market rent you enjoy from a building you happen to own. Getting those adjustments right, and being able to prove each one, can shift the valuation by a full turn of the multiple.
The 3 Ways to Value a Small Business
Professionals rarely rely on a single method. They apply up to three approaches and use each to sanity-check the others.
Each approach answers the value question from a different angle, so it helps to see them together.
| Approach | How it works | Best for |
|---|---|---|
| Income approach | Applies a multiple to SDE or EBITDA, or discounts projected cash flows to today | Profitable businesses with steady earnings |
| Market approach | Compares recent sale prices of similar businesses | Sectors with real Canadian transaction data |
| Asset approach | Values tangible and intangible assets, net of liabilities | Asset-heavy or low-profit businesses |
The income approach does most of the work for a healthy small business, and the market approach validates it against real deals. As Chartered Professional Accountants of British Columbia has noted, comparable Canadian sales are far harder to find than comparable homes, so a clean income-based business valuation usually carries the most weight.

SDE and EBITDA Multiples: Where the Number Comes From
The multiple is where owners fixate, and where the biggest misunderstandings live.
As a rough guide, many small businesses trade around two to four times SDE, and small to mid-sized companies around three to six times EBITDA, though the range depends heavily on industry, size, and risk. Treat those figures as a starting point rather than a promise, because a real multiple is earned by the specifics of your business.
Two cautions matter for Canadian owners. First, most published rule-of-thumb multiples rely on US data that may not fit your market or industry. Second, a multiple applied to a shaky earnings figure just produces a shaky value, so the quality of your normalized numbers matters more than the multiple you hope for.
A valuation based on revenue alone is the least reliable of all, though it appears constantly in online calculators. For why that shortcut misleads, see our explainer on how to value a business based on revenue.
What Moves Your Multiple Up or Down
Two businesses with identical earnings can sell for very different prices, and the difference is risk.
A buyer pays a higher multiple when the earnings look durable and a lower one when they look fragile. These are the factors that move the number most:
- ●Recurring revenue: predictable, repeat income earns a higher multiple than one-off project work.
- ●Customer concentration: a book spread across many clients is safer than one where a few accounts drive most of the revenue.
- ●Owner-dependency: a business that runs without the owner keeps its value after the sale; one that does not is priced down.
- ●Growth and margins: a credible growth story and healthy, stable margins lift the multiple; declining margins pull it lower.
Value is something you can build before you sell. One growth-stage business we worked with had strong operations but leaned on a single revenue segment and underpriced its core offering, which capped its value. After we rebuilt its pricing and installed disciplined performance metrics, sales grew 200 percent within a year and its enterprise value climbed with them.

Valuing for the After-Tax Result
The valuation that decides your retirement is not the sale price but what remains after tax, which is why structure belongs in the conversation from the start.
Deal structure drives the gap. In an asset sale, the buyer purchases specific assets and the seller cannot use the Lifetime Capital Gains Exemption. In a share sale, the buyer purchases the shares of your corporation and a qualifying seller may claim it.
A qualifying share sale can shelter eligible gains on qualified small business corporation shares up to a $1.25 million base for dispositions on or after June 25, 2024, with indexation resumed in 2026, so confirm the exact current-year figure before you rely on it. The capital gains inclusion rate, the taxable portion of a gain, remains one-half after the government cancelled the proposed increase to two-thirds.
Consider two owners who each sell for $2 million. One sells qualifying shares and shelters a large part of the gain through the exemption, while the other sells assets and shelters none. Same headline price, and yet the after-tax funds the two walk away with can differ by hundreds of thousands of dollars.
The practical takeaway is that a lower headline price with a share structure can beat a higher one taxed as an asset sale. Weigh the tax implications of selling a business in Canada alongside the valuation, never after it.
Frequently Asked Questions (FAQs)
Below are answers to questions we hear most often from owners preparing to sell.
Conclusion
Valuing a small business for sale comes down to one thing: proving the profit a new owner can rely on, then defending that number against a buyer who wants it lower.
The owners who sell well know their maintainable earnings, understand what drives their multiple, and structure the deal for the after-tax result before they ever set an asking price. A calculator cannot do any of that.
Remember: your business is worth what a prepared buyer will pay for provable earnings, rather than what an online estimate suggests.
At JS CPA Strategic Solutions, we value founder-led businesses and structure the sale so the after-tax result is protected from day one.
