What Is SDE (Seller's Discretionary Earnings)?
SDE is the number most small businesses are priced on. Here is what it means, how it is calculated, and how to judge whether the add-backs are legitimate.
If you're buying or selling a small business, one term comes up more than almost any other: SDE. It's the number most small businesses are priced on, and understanding it is essential to knowing whether a business is fairly valued. This guide explains what SDE is, how it's calculated, and how it's used — in plain language.
This article is part of our complete guide to how to buy a business in Canada and pairs closely with our guide to how to value a business in Canada.
What SDE means
SDE stands for Seller's Discretionary Earnings. It represents the total financial benefit a business provides to a single owner-operator over a year. In other words, it answers the question: "If I bought this business and ran it myself, how much money would it actually put in my pocket?"
SDE is used because a small business's official net profit often understates the real benefit to an owner. Owners frequently run personal expenses through the business, pay themselves a salary, and record one-time costs — all of which reduce reported profit but don't reflect the true earning power a new owner would inherit. SDE adjusts for these to show the real picture.
How SDE is calculated
SDE starts with the business's net profit (or net income) and adds back several items:
- The owner's salary and benefits — because a new owner would take this themselves.
- Personal or discretionary expenses run through the business (e.g. a personal vehicle, travel, or memberships that aren't essential to operations).
- One-time or non-recurring expenses — costs that won't repeat, like a one-off legal bill or equipment purchase.
- Interest, depreciation, and amortization — non-operating or non-cash items.
The formula, simplified:
SDE = Net profit + owner's salary + discretionary expenses + one-time expenses + interest/depreciation/amortization
These add-backs are why a business showing modest net profit on paper can have a much healthier SDE — and why verifying the add-backs is a key part of due diligence.
Why SDE matters when buying
Most small businesses are priced as a multiple of SDE. If a business has an SDE of $250,000 and sells at a 3x multiple, the asking price would be around $750,000. So SDE directly drives the price — which means two things for a buyer:
- A higher SDE justifies a higher price. Understanding SDE tells you whether the asking price is reasonable for the earnings.
- Add-backs must be legitimate. Sellers sometimes inflate SDE with aggressive or questionable add-backs to justify a higher price. Part of your job as a buyer is to verify that each add-back is real and reasonable. Learn what to check in our due diligence checklist.
SDE vs. EBITDA
SDE and EBITDA are related but used for different sizes of business. SDE is used for smaller, owner-operated businesses and adds back the owner's salary (since one owner-operator runs the business). EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) is used for larger businesses that have a management team separate from ownership, and it does not add back an owner's salary. As a rough guide: smaller owner-run businesses are valued on SDE; larger ones on EBITDA.
The bottom line
SDE is the single most important number in small-business valuation. It shows the true earnings a new owner would inherit, and it's what the asking price is usually built on. Understand it, verify the add-backs, and you'll be able to judge whether a business is fairly priced.

SDE calculator
Estimate Seller's Discretionary Earnings by adding legitimate owner add-backs back to pre-tax profit.
Bottom-line profit from the income statement or T2 return.
This is the starting point — earnings before tax, before any owner adjustments. Every add-back below is layered on top of it, so if this number is wrong, everything downstream is wrong.
Ask the seller
- Can I see three years of financial statements and matching T2 returns?
- Are the statements review-engagement, audited, or internally prepared?
- Do the tax returns reconcile to the statements? If not, what explains the gap?
- Is any revenue recognized before it's earned, or any expense deferred?
Verify with: 3 years of financial statements + T2 returns + year-to-date internals
Common add-backs
One working owner's total compensation, including management fees paid to yourself.
The current owner pays themselves whatever suits their tax plan, not market rates. SDE measures what the business earns for one working owner, so that compensation goes back in — but only for one owner.
Ask the seller
- Exactly how much did you take out in salary, dividends, bonuses, and management fees each year?
- How many hours a week do you actually work in the business, and doing what?
- Are any other family members or partners drawing compensation?
- If I hired a manager to do your job, what would that role pay?
Verify with: T4s, T5s, payroll journal, management-fee invoices
Personal vehicle, phone, travel, health or life insurance run through the business.
Personal costs run through the company depress reported profit but disappear when you take over. They only count if they're genuinely discretionary and clearly identified in the books.
Ask the seller
- Which specific expense accounts contain personal spending, and how much per year?
- Are any vehicles on the books personal, and will they stay with the business?
- Are personal travel, meals, or memberships coded to business accounts?
- Can you point to the exact general-ledger lines for each of these?
Verify with: General ledger detail, credit-card statements, vehicle lease agreements
Financing costs tied to the current owner's debt, not the operation itself.
Interest reflects how the current owner financed the business, not how it operates. Your own financing will look different — but note that if debt funds working capital the business genuinely needs, you'll carry a similar cost.
Ask the seller
- What loans, lines of credit, and leases sit on the books, and what are the balances?
- Which debts are being paid off at closing versus assumed by me?
- Is the operating line drawn to fund seasonal working capital?
- Are any loans personally guaranteed or tied to shareholder accounts?
Verify with: Loan agreements, amortization schedules, notes to the financial statements
Non-cash accounting charges. Add back, but budget for real equipment replacement.
D&A is an accounting entry, not cash leaving the bank, so it's added back. The catch: equipment really does wear out. Add it back, then subtract a realistic annual replacement budget before you decide what you can pay.
Ask the seller
- What's the age and condition of the major equipment?
- What did you actually spend on capital purchases in each of the last three years?
- What needs replacing in the next 24 months, and what will it cost?
- Is anything leased rather than owned, and does the lease transfer?
Verify with: Fixed-asset schedule, CCA schedule, capex history, equipment inspection
A lawsuit, a one-off rebrand, a flood repair — costs a new owner won't repeat.
Genuinely unrepeatable costs distort a single year's earnings. This is the most-abused add-back line, so each item needs a date, an amount, and a documented reason it can't recur.
Ask the seller
- Itemize every one-time expense with the date, amount, and reason.
- Has anything similar appeared in any of the other three years?
- Was the legal matter fully resolved, and is there any remaining exposure?
- Was the cost reimbursed by insurance, and is that reimbursement in revenue?
Verify with: Invoices, legal settlement documents, insurance claims, prior-year GLs
Only the portion above what you'd pay an arm's-length employee for the same work.
Family on payroll is common for tax reasons. Only the premium over market pay is an add-back — if the person does real work, you'll have to pay someone to do it after closing.
Ask the seller
- Who on payroll is related to you, and what does each of them actually do?
- How many hours a week do they work?
- What would an arm's-length hire cost for the same role?
- Will they stay on after the sale, and on what terms?
Verify with: Payroll register, T4s, job descriptions, comparable wage data
If the business pays above or below market rent to the owner, adjust to market.
When the owner also owns the building, rent is often set for tax convenience rather than market reality. Normalize it to market rent — the adjustment can be positive or negative.
Ask the seller
- Do you own the premises personally or through a holding company?
- What rent does the business pay, and how was that figure set?
- What's market rent per square foot for comparable space in this area?
- Will I get a lease at closing, what term, and what are the renewal options?
Verify with: Lease agreement, property tax bills, a broker's market-rent comparables
What is not an add-back
- A second working owner's salary — the buyer must replace that labour.
- Recurring repairs or maintenance dressed up as 'one-time'.
- Marketing you cut last year but the business needs to keep revenue.
- Equipment purchases that repeat on a cycle.
- Anything you can't evidence in the financial statements or tax returns.
This calculator is a general estimate, not financial or legal advice. Verify every add-back against financial statements and tax returns, and confirm with a qualified accountant.
