What is an Add-back?

An add-back is an adjustment to a company’s reported earnings (net income or EBITDA) that accounts for expenses the new owner won’t incur, or that aren’t representative of normal ongoing operations.

Add-backs are used to derive two key M&A profitability metrics:

• SDE (Seller’s Discretionary Earnings): Net income + owner-specific add-backs (owner compensation, perks, personal expenses) + standard add-backs
• Adjusted EBITDA: EBITDA + one-time, non-recurring, and normalization add-backs (typically does NOT include all owner compensation, since EBITDA assumes a market-rate CEO)

The economic logic: if your reported earnings include $50K of expenses the new owner won’t have (your personal cell phone bill, vehicle expense, lunch meetings), the ‘true’ earnings to a new owner are higher by that $50K. Add-backs adjust for that — and at a 5x multiple, that $50K of add-backs is worth $250K of additional sale price.

Common Add-back Categories

Owner compensation and benefits

For SDE, the entire owner’s salary, bonus, health insurance, retirement contributions, and other benefits. For Adjusted EBITDA, only the difference between owner’s comp and what a market-rate CEO would charge (e.g., owner takes $400K; market is $250K; add-back $150K).

Personal expenses

Vehicle leases and gas, cell phones, internet, meals, travel, family on payroll at above-market comp, country club memberships, personal insurance run through the business. All legitimate add-backs if they’re genuinely personal.

One-time / non-recurring expenses

Legal settlements, M&A advisory fees, one-time consulting projects, severance for terminated employees, business interruption losses (storms, COVID, etc.), discontinued business lines. Things that genuinely won’t repeat.

Non-cash items (already in EBITDA but called out here for SDE)

Depreciation and amortization — for SDE calculations, these are added back because they don’t represent current-period cash outflows.

Interest expense

Removed from EBITDA and SDE calculations because the new owner will have their own financing structure — what the seller paid in interest doesn’t reflect what the buyer will pay.

Rent normalization

If the owner owns the building and charges the business above- or below-market rent, an add-back (or add-down) normalizes to market rate. Often used when the building is being sold separately or transferred to the buyer at market terms.

Discontinued or non-core business lines

Revenue and expenses from business lines being discontinued before closing — or being sold off separately — should be removed from the trailing financials.

Owner-specific perks not transferring

Country club memberships, charitable donations made in owner’s name, personal travel disguised as business travel. Often the most contested category in QofE diligence.

Rules of Thumb for Add-backs

Some industry-standard guidelines for what’s reasonable:

• Total add-backs should be no more than ~15–25% of total reported expenses in most businesses. Higher percentages invite intense buyer scrutiny.
• Every add-back needs documentation. Vendor invoices, bank statements, payroll records — whatever proves the expense was personal/one-time/non-recurring.
• One-time means actually one-time. If ‘one-time legal expenses’ appear three years in a row, they’re not one-time.
• Personal expenses need to be defensibly personal. The personal cell phone you also use for business? Hard to claim as 100% personal. The country club membership you use exclusively for business entertaining? Hard to claim as 100% personal either.
• Owner compensation normalization needs a defensible market reference. Industry surveys, comparable searches, or peer-company data. Saying ‘the new owner won’t need a CEO at all’ doesn’t fly unless the business genuinely runs without one.

Common Add-back Mistakes

Padding for negotiation

The temptation to throw in marginal add-backs ‘to leave room for negotiation’ backfires. Buyers’ QofE accountants are very good at spotting weak add-backs, and the credibility loss from a few sketchy add-backs damages negotiating position on the legitimate ones.

Adding back items already in EBITDA

Don’t double-add. Depreciation is already added back to get to EBITDA; don’t add it back again to get to Adjusted EBITDA.

Forgetting offsetting expenses

If you’re adding back $40K of owner-paid health insurance, remember the new owner will probably need to pay for someone’s health insurance (their replacement employee or themselves). Don’t claim 100% of an expense as an add-back if a replacement cost will exist.

Inconsistent categorization across years

If you’re claiming ‘family member salary’ as an add-back in 2024 but didn’t categorize it that way in 2022, buyers will question whether you’re cherry-picking. Apply add-back categorization consistently across all years presented.

Missing supporting documentation

Verbal ‘trust me’ explanations don’t survive QofE. Every add-back needs paper trail: vendor invoices showing personal use, payroll records showing family compensation, board minutes documenting one-time expense decisions.

How to Prepare Your Add-backs

• Build the add-back schedule before going to market. Trying to assemble it during diligence (with a buyer waiting) creates pressure to overstate.
• Document each line item with supporting paper. If you can’t show the documentation, don’t add it back.
• Be conservative. Sell-side QofE reports typically include a defensible add-back schedule; aggressive sellers see meaningful price reductions in diligence.
• Categorize consistently across years. Trailing 3-year EBITDA and add-back schedules should use the same categorization throughout.
• Separate ‘definite’ from ‘arguable’ add-backs. Present the definite ones cleanly; treat arguable ones as upside discussion, not core valuation drivers.
• Consider a sell-side QofE for deals above ~$10M. The cost ($25K–$60K) almost always pays for itself in preserved value during buyer diligence.
