SDE in one paragraph
Start with reported profit, then add back owner compensation you would replace, personal expenses run through the business, and truly non-recurring costs. Some analyses also adjust interest, taxes, depreciation, and amortization depending on the framework — but for many main-street deals, the headline number buyers repeat is SDE for a single owner-operator.
SDE is not EBITDA for a professionally managed company with a market-rate CEO already in place. If the business needs a full management team on day one, your story may shift toward a different earnings definition. Say what you are measuring.
Add-backs that often hold up
Credible add-backs are documented, non-essential to ongoing operations (or clearly replaceable), and visible on tax returns, payroll, or invoices.
- Owner salary and payroll taxes for the working owner being replaced.
- Personal auto, phone, travel, or insurance clearly not required for operations.
- One-time legal, storm repair, or relocation costs that will not repeat.
- Above-market rent paid to an owner-related entity — if you can show market rent evidence.
- Discretionary charitable or family expenses that a new owner would not continue.
Add-backs that usually fail
If the cost still happens next year under a new owner, it is probably not an add-back. Relabeling growth spending as 'one-time' is a classic diligence fight.
- Marketing or hiring you call one-time but still need to maintain revenue.
- Family wages with no plan to replace the work those people do.
- Capex disguised as repairs to inflate cash earnings.
- Personal expenses you cannot point to in the books.
- Stacked add-backs that imply the business runs itself with almost no labor.
How add-backs change a planning range
Buyers often think in terms of SDE times a planning multiple. Inflated SDE can temporarily widen your hopeful range — and then collapse when diligence cuts the add-backs. A tighter, defensible SDE usually supports a more useful conversation than a heroic bridge.
DealPilot's free planning range is informational, not a certified appraisal. Use it to see how revenue, owner profit, and involvement shape a private band before you argue add-backs with strangers.
Key takeaways
- SDE estimates cash benefit to one working owner-operator.
- Good add-backs are documented and non-recurring or personal.
- Costs the next owner still needs are not add-backs.
- Defensible SDE beats inflated SDE in diligence.
