An add-back is a cost in your accounts that a new owner wouldn’t carry. Added back to profit, it reveals the business’s true earning power. Get them right and you raise the price; overreach and you damage the credibility of the entire schedule.
Why add-backs matter so much
SMEs are valued on a multiple of Adjusted EBITDA. That means every accepted add-back is multiplied:
The reverse is also true: a rejected add-back costs you the same amount, plus some of the buyer’s trust in the rest of your numbers. Buyers and their accountants re-derive every add-back in due diligence — the schedule isn’t taken on faith.
The safe list — usually accepted with evidence
| Add-back | Evidence buyers expect |
|---|---|
| Above-market owner salary (the excess over a replacement manager) | Payroll records + a market salary benchmark for the replacement role |
| Personal expenses through the business (vehicle, travel, family phones, home costs) | Ledger lines + invoices showing the personal nature |
| Genuine one-offs (a legal settlement, flood damage, a relocation) | The invoice and a plain reason it won’t recur |
| Owner-only insurance & benefits (life cover, private health via the company) | Policy documents in the owner’s name |
| Non-operating costs (interest, one-time professional fees on this sale) | Already excluded in EBITDA by definition — just show the workings |
The contested list — expect a negotiation
- Below-market rent from a related party. If you own the premises and charge the company less than market rent, buyers adjust EBITDA down to market rent — this one can go against you.
- Family members on payroll. Only the portion above market rate for work actually done is an add-back. “My spouse does the books for $80k” becomes an add-back only above what a bookkeeper costs.
- “One-off” marketing pushes or repairs. If something similar appears in two of the last three years, buyers treat it as recurring.
- COVID-era distortions. Still arguable for 2020–22 comparatives, but the further they recede, the less weight they carry.
The rejected list — don’t submit these
- Recurring maintenance dressed up as capital or one-off costs (buyers check the fixed asset register and prior years).
- Marketing the business genuinely needs to hold revenue — cutting it isn’t an add-back, it’s a different (smaller) business.
- Wages for people doing real, necessary work.
- Vague “discretionary spending” with no ledger trail. If you can’t point to the line item, it doesn’t exist.
A worked example
From reported profit to Adjusted EBITDA
At a 4× multiple, the accepted add-backs above add roughly $564,000 to the indicative value versus reported EBITDA — and the honest rent adjustment costs $88,000. Both belong in the schedule: buyers find the rent issue anyway, and disclosing it first protects the rest.
How buyers test your add-backs
Serious buyers (and platforms like BuyBuildSell) don’t read the add-back schedule — they rebuild it. Expect year-by-year comparisons to catch “one-offs” that recur, payroll cross-checks against market rates, and forensic checks on expense patterns. The methods are standard: the Australian Government’s valuation guide describes the same normalisation process — adjusting for owner salaries and one-off expenses — that every professional valuer applies.

Frequently asked questions
What is an EBITDA add-back?
A cost in the accounts that a new owner wouldn’t carry — added back to profit to show true ongoing earning power. Adjusted EBITDA = EBITDA + defensible add-backs.
Which add-backs do buyers always accept?
The excess portion of an above-market owner salary, clearly personal expenses, and documented one-offs — each with payroll records, invoices and a replacement-cost assumption behind it.
Which add-backs do buyers reject?
Recurring costs dressed as one-offs, marketing or maintenance the business needs, wages for real work, and anything without a paper trail.
How much is an add-back worth on the sale price?
Every accepted dollar of Adjusted EBITDA is multiplied by the deal multiple — at 4×, a $50,000 add-back is worth $200,000. Rejected add-backs cost the same, plus credibility.
What evidence do I need?
For each item: the ledger line, the invoice or payroll record, why a new owner wouldn’t incur it, and the market rate for any replacement role. Buyers re-derive the whole schedule in due diligence.
