Buyers do not value your business on the profit line of your tax return. They value it on 'normalized' earnings — and the two metrics that matter are SDE and EBITDA. Knowing which one applies to you, and why, is the difference between a realistic price and a confusing one.
- SDE = earnings plus the owner's salary, perks, and one-time costs — used for smaller, owner-operated businesses.
- EBITDA excludes an owner's salary because it assumes a hired manager — used for larger businesses.
- Add-backs restate earnings to show true owner benefit; they must be documented and defensible.
- The same business can show very different numbers under each metric — context decides which buyers use.
- Inflated add-backs get removed in diligence and erode trust; credibility beats aggression.
What SDE measures
Seller's Discretionary Earnings is the total financial benefit a single owner-operator receives from the business. You start with net profit and add back the owner's salary, owner perks, interest, taxes, depreciation, amortization, and one-time expenses. SDE answers the question a hands-on buyer is really asking: 'If I run this business myself, how much will it put in my pocket?' It is the standard for smaller, owner-run businesses.
What EBITDA measures
EBITDA — earnings before interest, taxes, depreciation, and amortization — assumes the business is run by a hired management team rather than the owner. Crucially, it does not add back an owner's salary, because a buyer would pay a manager to do that job. EBITDA is the standard for larger, more established businesses where ownership and management are already separate.
A simple worked example
Imagine a business with $200,000 in net profit. The owner also pays themselves a $120,000 salary, runs a $10,000 personal vehicle through the business, and had a one-time $15,000 legal expense this year. Under SDE, you would add those back: roughly $200,000 + $120,000 + $10,000 + $15,000 = about $345,000 of discretionary earnings.
Under EBITDA, you would not add back the owner's salary (a buyer must replace that role), so the normalized figure is far lower. Same business, two very different numbers — which is exactly why using the right metric for your size and structure matters.
Add-backs: the detail that moves the number
Add-backs are where valuations are won or lost. Legitimate examples include one-time costs, personal expenses run through the business, and above-market owner compensation. Each defensible add-back increases the earnings your multiple is applied to.
- Document every add-back with support a buyer's accountant can verify.
- Stick to genuinely one-time or genuinely personal items.
- Avoid 'aggressive' add-backs that recur or that you cannot prove — they get removed in diligence.
- Remember the goal: a higher number that survives scrutiny, not a higher number that collapses.
Which metric applies to you
As a rule of thumb, smaller owner-operated businesses are valued on SDE, while larger businesses with a management layer in place are valued on EBITDA. There is no hard dividing line, but businesses with earnings above roughly one to two million dollars and a real management team are more often valued on EBITDA. A broker will tell you which framework the buyers in your size range and industry will actually use, and prepare your financials accordingly.
Why this matters for your sale
If you compare your business to a published 'multiple' without knowing whether that multiple was applied to SDE or EBITDA, you can badly misjudge your value. The metric and the multiple are a matched pair. Getting both right — and presenting clean, well-documented earnings — is the foundation of a credible asking price.
Frequently asked questions
Is a higher SDE or EBITDA always better?
A higher normalized earnings figure generally means a higher valuation — but only if it is defensible. Add-backs that cannot survive due diligence will be removed and can damage buyer confidence, hurting the deal.
At what size does a business switch from SDE to EBITDA?
There is no hard line, but businesses with earnings roughly above one to two million dollars and a management team in place are more often valued on EBITDA. Your advisor will confirm which buyers will use.
Do buyers really add back my car and personal expenses?
Legitimate, documented personal or one-time expenses are commonly added back in an SDE calculation, because they reflect discretionary owner benefit rather than the cost of running the business. They must be verifiable.
Which multiple goes with which metric?
Multiples quoted on SDE are generally lower numbers than multiples quoted on EBITDA, because SDE is a larger earnings figure. Always confirm which metric a quoted multiple refers to before comparing.
