Seller's discretionary earnings is commonly used to discuss owner-operated businesses. A simplified starting formula is net income plus one owner's compensation and benefits, interest, taxes, depreciation and amortization, plus genuinely discretionary or non-recurring expenses. But the label does not make an add-back real.
What SDE is trying to show
SDE approximates the pre-tax financial benefit available to one working owner before acquisition debt. It is not free cash flow, salary, EBITDA, a tax measure or cash available after debt service. It also does not account automatically for working capital, maintenance capital expenditures or the cost of replacing the owner.
It is best treated as a search and comparison convention, not a verified result. A Canadian buyer still needs a transaction accountant and valuator to reconcile the company records, test every adjustment and account for the intended ownership structure.
A line-by-line normalization
Illustrative GTA service company:
| Reported net income | $118,000 |
| Owner salary | +$105,000 |
| Owner health/vehicle benefits | +$16,000 |
| Interest | +$14,000 |
| Income taxes | +$20,000 |
| Depreciation/amortization | +$18,000 |
| Documented one-time legal matter | +$9,000 |
| Seller-proposed “growth hire” add-back | +$42,000 |
| Seller-proposed personal travel | +$11,500 |
| Buyer-normalized SDE before disputes | $310,500 |
The $42,000 “growth hire” is rejected if that employee performs ongoing work the buyer needs. The $11,500 travel add-back is accepted only to the extent invoices and purpose prove it was personal and it was properly recorded. If $3,000 remains unsubstantiated, accept $8,500.
Classify add-backs instead of arguing in one pile
Usually defensible with evidence
- One working owner's T4 salary and employer-paid benefits, if the buyer will perform that role.
- Interest, income taxes, depreciation and amortization, subject to the chosen convention.
- Clearly personal expenses recorded through the company.
- A completed, genuinely non-recurring event with invoices.
Frequently disputed
- Above-market family compensation - normalize to market cost, not zero.
- Vehicle, travel, meals and home-office expenses with mixed purposes.
- Professional fees described as one-time when similar fees recur.
- Repairs described as extraordinary when maintenance has been deferred.
- Temporary labour or overtime likely required after closing.
Usually rejected
- Future revenue or “profit the buyer could make.”
- Expenses the buyer plans to cut but has not eliminated.
- Necessary employees labeled discretionary.
- Normal marketing, software, insurance or compliance costs.
- Owner compensation when a replacement manager must be hired, unless replacement cost is deducted.
Normalize for the buyer's intended role
| Defensible SDE | $265,500 |
| Replacement general manager, loaded | ($110,000) |
| Maintenance capex reserve | ($18,000) |
| Operator-adjusted earnings before debt | $137,500 |
A 3× price based on SDE is $796,500. But an absentee buyer is not buying $265,500 of passive cash flow. They are buying $137,500 before acquisition debt in this scenario.
How to verify the recast
- Reconcile financial statements to T2 corporate tax returns and notices of assessment.
- Trace add-backs to the general ledger, bank/credit-card evidence and invoices.
- Compare monthly results across at least three years and year to date.
- Inspect payroll, related-party payments and owner duties.
- Normalize rent, compensation and services to market where related parties are involved.
- Separate working-capital needs and maintenance capital from SDE.
- Run downside cases for revenue, gross margin, client loss and interest rate.
BDC notes that valuation is not exact and may use earnings, market or asset approaches. A multiple applied to an unverified recast is not a valuation.

Give every adjustment an evidence grade
Grade A adjustments reconcile to tax returns, bank records, payroll or invoices. Grade B adjustments are supported by internal records and a credible explanation. Grade C adjustments rely primarily on seller assertion. Exclude Grade C from the base case and show it only as upside pending evidence.
Normalize the labour before the lifestyle
Owner compensation is not automatically removable. Document every recurring duty, estimate weekly hours, decide which duties the buyer will perform and price the rest at a fully loaded market cost. Do the same for unpaid relatives and family members paid above market. The business does not care whose surname was on the payroll; the work still has to happen Monday morning.
Carry normalized SDE through to cash after debt
| Normalized SDE | $360,000 |
| Replacement operator for duties the buyer will not perform | − $120,000 |
| Recurring capital expenditure | − $25,000 |
| Annual acquisition debt service | − $145,000 |
| Pre-tax cash remaining | $70,000 |
A listing can advertise $360,000 of SDE while the buyer's structure leaves only $70,000 before tax and unexpected needs. That does not automatically make the deal unattractive; the buyer may personally perform the operator role. It does make the job, leverage and return visible. Use the calculator to keep these layers separate.
