EBITDA Add-Backs Explained: What You Can (and Cannot) Legitimately Add Back Before Selling
If you're preparing to sell a business, you'll hear "add-backs" and "normalised EBITDA" constantly — and you'll also hear, from anyone who's actually been through a sale, that overstated add-backs are the fastest way to lose a buyer's trust mid-negotiation.
What an add-back actually is
Reported EBITDA is what your accounts say. Normalised EBITDA is what the business would generate under different, more "standard" ownership — stripping out expenses that are specific to how you happen to run it today, not what the business fundamentally costs to operate.
The five categories that hold up under scrutiny
Owner compensation add-back. If you pay yourself more than it would cost to hire a manager to do your job, the excess — not your full salary — is a real add-back.
One-time / non-recurring expenses. Genuinely one-off costs: a lawsuit, a flood, a one-time system migration. Not the normal cost of doing business, even if it felt unusual at the time.
Personal expenses run through the business. Common, but the category buyers and lenders scrutinise hardest. Only include amounts you can actually document.
Related-party rent adjustment. If you pay yourself or a relative above or below genuine market rent, the difference is a real, common adjustment.
Other, well-documented add-backs. Everything else needs independent documentation before you rely on it in a real conversation.
The test that actually matters
If you can't explain and document an add-back in one sentence to a stranger, it probably shouldn't be in there. A buyer's accountant will challenge every single one — the add-backs that survive are the ones you were conservative about from the start.
The Business Sale Readiness & Valuation Toolkit computes this for you with a real formula — the owner-compensation add-back is even floor-capped automatically so you can't overstate it by accident — alongside a full valuation model and sale-readiness assessment.
