Which SDE Add-Backs Should a Buyer Trust?
A practical buyer’s guide to testing SDE add-backs, spotting recurring costs dressed as one-time expenses, and asking for real support.
# Which SDE Add-Backs Should a Buyer Trust?
An add-back is an expense that appears in the business records but is added back to profit when calculating seller’s discretionary earnings.
Some add-backs are sensible. Some are optimistic. Some have apparently been raised in the wild by wolves.
The practical test is not whether an expense has been labeled “add-back.” The test is whether the expense is documented and whether you, as the new owner, can reasonably avoid it.
Four questions for every add-back
For each adjustment, ask:
- Did the business really pay it? Find it in the tax return, profit-and-loss statement, general ledger, invoice, or bank record.
- Is the amount correct? A label and a round number are not supporting documentation.
- Will the expense stop after closing? If you must keep paying it, it is not extra earnings.
- Is another cost hiding behind it? Removing the seller’s salary is not free if you must hire somebody to perform the work.
An add-back should pass all four tests, not merely be described with confidence.
Add-backs that may be reasonable
One working owner’s compensation and benefits
SDE commonly adds back one owner’s compensation because the measure is intended to show the total benefit for one owner-operator.
But identify the work attached to that compensation. If you will do it, the earnings include payment for your labor. If you will not, include a replacement cost.
Clearly personal expenses
A seller may run personal vehicle costs, travel, insurance, or other benefits through the business. These can be reasonable adjustments when they are documented, permitted, and genuinely unnecessary for the buyer.
Do not assume every vehicle, meal, or phone expense is personal. The pest-control truck still needs fuel after the seller moves to Florida.
Interest, depreciation, and amortization
These are commonly considered when recasting earnings, but “added back” does not mean “economically irrelevant.”
Depreciation is a noncash accounting expense, yet the equipment being depreciated may eventually need replacement. A laundromat full of aging machines does not become maintenance-free because depreciation is noncash.
Truly nonrecurring expenses
A one-time legal settlement, unusual relocation cost, or casualty repair may qualify if it is documented and unlikely to recur.
The phrase “one-time” deserves a multiyear review. A business with one different “one-time” repair every year has discovered recurring expenses wearing fake mustaches.
Add-backs that deserve skepticism
Expected future savings
The seller may say you can renegotiate rent, reduce advertising, eliminate staff, or buy supplies more cheaply.
Those are possible improvements, not historical add-backs. Treat them as a separate upside case after you have evidence.
Underpaid family labor
If a spouse handles bookkeeping and a child covers weekends without market wages, the business may need additional payroll after closing. That is usually a missing cost, not an add-back.
Deferred maintenance
Skipping repairs can make one year look profitable. It does not make the underlying need disappear. Inspect equipment and estimate normal maintenance and replacement spending.
Recurring “extraordinary” expenses
Review at least several years. Legal bills, recruiting costs, technology work, vehicle repairs, or customer refunds may fluctuate while remaining normal parts of the business.
The buyer’s hoped-for efficiencies
Maybe you can run better advertising, negotiate insurance, automate bookkeeping, or combine the company with another operation. Wonderful. Those improvements belong in your plan, not in the seller’s historical earnings.
Build three versions of earnings
Instead of arguing about one magical SDE number, create three views:
| View | Purpose |
|---|---|
| Seller-reported SDE | Understand the listing and asking price |
| Verified SDE | Include only adjustments supported by records |
| Buyer-adjusted cash flow | Reflect your staffing, compensation, maintenance, and operating plan |
This prevents a negotiation convention from quietly becoming a personal-income forecast.
Why small add-backs have large effects
Suppose a business claims $150,000 of SDE and is priced at 3× SDE, or $450,000.
If $25,000 of add-backs do not survive review, supported SDE falls to $125,000. At the same 3× multiple, the indicated price falls to $375,000.
That questionable $25,000 did not create a $25,000 pricing problem. It created a $75,000 pricing problem—and may also reduce the cash available for debt payments.
This is why add-back review is not accounting trivia.
A useful request to send the broker
Ask for:
- The detailed SDE reconciliation for each year
- The tax return and profit-and-loss statement used as the starting point
- General-ledger detail for every material adjustment
- Invoices, receipts, payroll records, or contracts supporting the adjustments
- An explanation of what the owner and unpaid family members do
- Capital-expenditure and repair history
You are not accusing anybody of dishonesty. You are asking the number to show its work.
The five-part test
A trustworthy add-back is:
- Actually recorded
- Correctly measured
- Supported by evidence
- Unlikely to continue
- Not replaced by another necessary cost
If an add-back requires a long story but has no receipt, ledger entry, or operational explanation, keep your eyebrow raised.
