Normalised EBITDA and add-back calculator

Buyers do not value reported profit. They value the sustainable earnings a new owner would inherit, which means adding back owner-specific and one-off items — and defending every one of them.

  • Every add-back needs documentary evidence — unsupported items are removed in due diligence.

How to use this calculator

  1. 1Enter net profit, then interest, tax, depreciation and amortisation to build EBITDA.
  2. 2Add owner remuneration above market, above-market rent and one-off costs.
  3. 3Apply your expected multiple to see the value impact.

Which add-backs survive due diligence

Legitimate: above-market owner salary, related-party rent above market, genuinely one-off legal or restructuring costs, personal vehicles and travel run through the business, discontinued product losses.

Rejected: recurring costs described as one-off, marketing that would need replacing, deferred maintenance, and any add-back without documentary evidence. A buyer's accountant removes anything unsupported, and each removed dollar costs you the multiple.

The multiplier effect

At a 4x multiple, every 10,000 of accepted add-back adds 40,000 to enterprise value. That is why preparing add-back evidence twelve months before a sale returns more than almost any operational change.

Replace the owner's salary with a market rate for the role rather than adding back the whole amount — buyers need to employ someone to do the work.

Frequently asked questions

What is the difference between EBITDA and SDE?

SDE (seller's discretionary earnings) adds back one full-time owner's total remuneration and is used for smaller owner-operated businesses. EBITDA assumes a market-rate manager and is used above roughly 1m of earnings.

How far back should add-backs go?

Usually the trailing twelve months, cross-checked against the prior two years. A one-off that appears in all three years is not one-off.

Do buyers accept COVID or one-off event adjustments?

Sometimes, with clear evidence of both the cost and the recovery. Present them separately so the rest of your normalisation is not tainted by a contested item.
