What Is Seller's Discretionary Earnings (SDE) in Pest Control — Complete Explanation

SDE Defined

Seller's Discretionary Earnings (SDE) represents the total economic benefit available to a single full-time owner-operator of a business. It starts with net income (as reported on the tax return) and adds back several categories of expenses that are discretionary to the owner rather than necessary for business operations. SDE is used instead of EBITDA for most pest control businesses under $3M in revenue because these businesses are typically owner-operated and the owner's compensation is a significant variable.

The SDE Calculation

The standard SDE calculation for a pest control business is: Net Income + Owner's W-2 Salary + Owner's Health Insurance + Owner's Auto Allowance/Vehicle Depreciation + Owner's Cell Phone + Depreciation + Amortization + Interest Expense + One-Time or Non-Recurring Expenses = SDE. Each category deserves scrutiny — buyers and their accountants will verify every add-back with documentation.

• Net Income: from Schedule C (sole prop) or Form 1120/1120S (corporation)
• Owner W-2: only the owner-operator's compensation, not a market management replacement salary
• Personal expenses: only documented expenses that flow through the business for the owner's personal benefit
• Depreciation/Amortization: added back because these are non-cash charges
• One-time items: expenses that occurred in one year and won't recur (legal settlements, equipment replacements, disaster recovery)

Legitimate Add-Backs vs. Red Flags

Not all add-backs are created equal. Buyers accept some readily and scrutinize others heavily. The difference between a clean SDE calculation and a problematic one often determines deal certainty — even if the numbers are close.

• Readily accepted: owner W-2 salary, documented personal vehicle, health insurance, depreciation
• Scrutinized: personal travel and meals, home office expenses, family members on payroll
• Red flags: undocumented cash revenue, owner loan repayments characterized as expenses, excessive personal expenses with no documentation
• Non-recurring: legal costs from resolved disputes are accepted; recurring legal costs are not

Why SDE Matters More Than Revenue

Two pest control businesses each generating $1M in revenue can have dramatically different SDE figures — and therefore dramatically different sale prices. A business with $1M revenue, $200K in documented SDE trading at 4.5x is worth $900K. A business with $1M revenue, $400K in SDE trading at the same multiple is worth $1.8M. The driver of value is not top-line revenue — it's the cash flow available to the owner after all legitimate business expenses are paid. Sellers who conflate revenue with SDE consistently underprice or overprice their business.
