EBITDA Add-Backs: What They Are and How Buyers Test Them
Sam's List Editorial | 2026-10-28
EBITDA add-backs are adjustments an owner makes to reported earnings to show what the business would earn under a new owner. They matter because buyers and lenders often start from adjusted earnings, and every dollar of add-back that survives scrutiny can change how a deal is priced or financed. The ones that do not survive can cost an owner credibility along with the dollars.
This is a general explainer, not advice on your deal. What a buyer accepts depends on the buyer, the documents and the facts.
System Six, a Seattle bookkeeping and fractional CFO firm that lists Professional Service Firms among its specialties and works with small businesses generating $1 million to $10 million of revenue, is one firm to ask about preparing numbers like these. System Six is a vetted Sam's List member and a paying member of our featured program; payment does not buy the language we use or its reviews.
What EBITDA Add-Backs Are
EBITDA stands for earnings before interest, taxes, depreciation and amortization. It is a measure of operating earnings, not a figure that appears on a tax return, and different people calculate it with different adjustments. An add-back is an expense or a loss in the reported numbers that the owner argues should be removed, because it will not continue or does not reflect the business's normal operations.
The result is often called adjusted EBITDA. The word adjusted is the point: it is a story about the business, told with numbers, and a buyer will test it. A business with clean books and a short list of well-supported adjustments is easier to trust than one with a long list of large ones.
The limitation: no rule defines adjusted EBITDA for every deal. The purchase agreement or loan agreement usually defines it, so the definition in the document, not the one in a brochure, is the one that counts.
Common EBITDA Add-Backs Owners Claim
A few categories show up in most small-business deals. Owner pay above what a replacement manager would cost is the classic one, and an owner compensation add-back is a common adjustment in a small business. Personal expenses run through the company, such as a vehicle or a family member's cell phone, are another. One-time costs, such as a legal settlement or the expense of moving offices, are a third. Costs of the sale itself, such as advisory and diligence fees, are often added back too.
Each category has a version that is easy to defend and a version that is not. Owner pay is simplest when you can show what a hired manager would be paid. Personal expenses are simplest when receipts and bank records show they were personal. One-time costs are simplest when they truly happened once.
The limitation: an add-back for an owner who is leaving assumes someone else can do the job at the lower cost. If the owner is the main salesperson or the key relationship, a buyer may ask what replacing that work really costs.
How Buyers Test Adjusted EBITDA
Buyers, and the accountants who work for them, usually test an add-back on two questions: is it supported, and will it recur. Support means a document: an invoice, a bank statement, a contract, a payroll record. Recurrence means looking at several periods to see whether the cost shows up again under another name.
A one-time cost that appears every year is not one-time. A repair that recurs, a legal fee that comes back, a consultant who is hired again each spring will all be questioned. Buyers also check that the add-back is consistent with the rest of the financials: an owner who claims a large compensation adjustment but never paid the owner anything through payroll will draw questions.
A quality of earnings review is the formal version of this test, and a buyer's team may run one. It rebuilds the earnings from source records and reports which adjustments it accepts, which it rejects and which it flags for discussion.
The limitation: a buyer's review is the buyer's judgment. Two professionals can reach different answers on the same adjustment, and the one that matters is the one on the other side of the table.
Add-Backs That Draw Pushback
Some adjustments reliably get questioned. Ordinary marketing spend described as unusual is one. A pro forma cost saving, such as a vendor contract the new owner expects to renegotiate, is another, because it is a forecast and not a past cost. Revenue adjustments, such as a customer's pending contract added as if it were signed, get the toughest look of all.
Recurring costs relabeled as one-time are the most common problem. If a buyer finds the same item three years in a row, the entire list becomes less credible, not only that line. A shorter list of adjustments you can support beats a longer one you cannot.
The limitation: even a well-supported add-back may not move the price. How a buyer values earnings depends on the buyer's view of risk, growth and the market, and an adjustment that holds up can still be weighed against other concerns.
How to Document an Owner Compensation Add-Back and Other Adjustments
Start a schedule early, before a buyer or lender asks. List each adjustment, the amount for each period, what it was, why it will not continue and where the support sits. For owner compensation, note what the role involves and how a replacement would be paid. For personal expenses, tie each item to a statement.
Keep the books consistent with the story. If expenses were mixed with personal ones, clean the categories going forward, so a buyer looking at the last twelve months sees a business that is run, not just described. A schedule that ties to the general ledger is more persuasive than one assembled the week before a call.
The limitation: documentation does not change what happened. It shows it. If an adjustment depends on a fact you cannot support, leave it out rather than defend it later.
Where System Six Fits
System Six is a bookkeeping and fractional CFO firm based in Seattle, founded in 2009, with about 41 employees and serving clients nationwide. Its live profile lists Non-Profit Organizations, Professional Service Firms and Real Estate Investors as specialties. It says it serves small businesses generating between $1 million and $10 million of revenue and helps organizations modernize a finance function after an acquisition.
System Six does not yet have enough reviews on Sam's List for us to cite a count, so we describe the firm by what its profile says instead. Ask for client references from owners who prepared for a sale or a loan.
The limitation, plainly: the profile does not name add-backs, adjusted EBITDA or sell-side preparation, so ask what is included. It lists a $1 million revenue minimum, so a smaller business may fall outside it. A bookkeeping and fractional CFO firm does not replace a transaction advisor, an attorney or a valuation professional.
Frequently Asked Questions
What are EBITDA add-backs?
They are adjustments to reported earnings that remove costs an owner argues will not continue or are not part of normal operations. Common examples are above-market owner pay, personal expenses and one-time costs. The result is often called adjusted EBITDA. The deal documents define which adjustments count.
What is adjusted EBITDA?
It is EBITDA after add-backs and other adjustments, meant to show what the business earns for a new owner. It is not a tax figure and has no single definition, so check how a purchase or loan agreement defines it.
How do buyers verify an owner compensation add-back?
They compare it to what a replacement manager would cost and check payroll and tax records against the claim. They also ask whether the owner does work, such as selling, that the replacement cannot easily do. Evidence of market pay for the role helps.
When should an owner start preparing add-backs?
Before talking to buyers or lenders. Build the schedule while memories and records are fresh, keep the books consistent with it and ask your CPA to review it. A late scramble tends to produce a longer, weaker list.
If you may sell or borrow in the next year or two, start a schedule of adjustments with support for each line and ask your CPA to review it. You can browse fractional CFOs on Sam's List, including the firm above, and ask each what it prepares ahead of a sale.
