Normalize earnings by adjusting reported results only for changes you can explain and support. A defensible bridge shows both additions and deductions, including replacement management and appropriate rent. Keep EBITDA, SDE and cash flow clearly labeled.

Begin with the books
Choose a defined period and obtain the underlying profit and loss statement. Reconcile it with tax returns, the general ledger, bank activity and POS settlements. Record known accounting differences rather than treating one document as automatically wrong.
If you begin with net income, separately identify interest, income taxes, depreciation and amortization to calculate an initial EBITDA figure. Do not add those expenses again when starting from a figure already labeled EBITDA. Confirm which taxes are included: payroll taxes, sales taxes and property taxes do not become EBITDA add-backs just because their names contain the word tax.

Make each adjustment auditable
Use a schedule with the account, amount, date, reason, evidence and expected future treatment. Keep proposed adjustments separate from accepted ones. A seller’s explanation starts a discussion; it does not establish buyer acceptance.
A one-time professional fee related to an unusual matter may merit analysis. Regular accounting fees, recurring equipment repairs and an annual marketing campaign normally continue in some form. A cost described as discretionary can still be necessary for the buyer to maintain revenue.
Three checks before an expense becomes an add-back
Scroll sideways to compare columns. You can also focus the table and use the arrow keys.
| Check | Evidence to look for | What changes the answer |
|---|---|---|
| Was it actually deducted in the starting period? | Ledger account, invoice, posting date and treatment in the stated EBITDA. | A purchase capitalized on the balance sheet is not an operating expense to add back in full. |
| Will the economic cost stop after the sale? | Reason for the spending, earlier years and the buyer's operating plan. | A repair called unusual may be one of several different repairs required every year. |
| Is another item already offsetting it? | Insurance income, refunds, credits, reimbursements and related adjustments. | Adding a gross expense while retaining its reimbursement can overstate the benefit. |
Use one row for each proposed change, with a link to the supporting document and a status such as proposed, supported, disputed or accepted for this model. A missing invoice is an unresolved item, not permission to estimate an add-back. IRS recordkeeping guidance explains the role of underlying business documents; the transaction adjustment itself still requires analysis and agreement.
Keep expense adjustments separate from unrecorded revenue claims. An owner's estimate of cash takings or sales lost during rain, a closure or a broken pay station does not become verified historical EBITDA. Record the event and any alternative operating scenario separately, including the costs that would have accompanied the additional sales.

Account for the work the owner does
Document owner hours and responsibilities: managing staff, collecting cash, maintaining equipment, handling vendors and opening or closing the site. If those duties must be replaced, show a supportable replacement cost. A family member’s low salary may also need normalization upward.
SDE often considers the economic benefit available to one working owner under a stated convention. EBITDA used by an absentee or institutional buyer generally needs the labor required to run the business. Do not label an SDE figure normalized EBITDA simply because it is larger.
Example: replace owner labor once
In this separate illustration, reported EBITDA of $220,000 already deducts $90,000 of pay for an owner who does the management work. A supported replacement plan costs $105,000 in total, including the modeled employment burden. With no other changes, normalized EBITDA is $205,000: either add back $90,000 and deduct the full $105,000, or deduct only the $15,000 incremental cost from reported EBITDA.
Scroll sideways to compare columns. You can also focus the table and use the arrow keys.
| Bridge | Calculation | Result |
|---|---|---|
| Gross replacement bridge | $220,000 + $90,000 − $105,000 | $205,000 |
| Incremental replacement bridge | $220,000 − $15,000 | $205,000 |
| For a stated working-owner SDE convention | $220,000 + $90,000; the owner must perform the work | $310,000 before any other adjustments |
The $310,000 working-owner scenario and the $205,000 managed scenario describe different labor arrangements. They are not interchangeable earnings measures. If the owner takes distributions instead of a wage already expensed in the P&L, there may be no salary expense to add back. Start with the actual accounting and duties rather than the amount the owner withdrew.
The earnings worksheet asks for additional replacement labor above the cost already in the books. To reproduce this management example, enter reported EBITDA of $220,000, supported additions of $0, additional replacement labor of $15,000 and rent adjustment of $0. The original $190,000 worked example below uses different facts and remains separate.
A worked earnings bridge
Illustrative example: reported EBITDA is $220,000. The seller proposes adding $15,000 of documented personal expenses and $10,000 of a nonrecurring professional fee. A buyer identifies $35,000 of incremental management cost and $20,000 of additional annual rent required under the proposed lease.
The resulting scenario is $190,000: $220,000 + $15,000 + $10,000 − $35,000 − $20,000. Each item remains subject to verification. Omitting the two deductions would produce $245,000 and a materially different pricing discussion.
Our earnings worksheet begins with reported EBITDA, not net income. If your starting point is different, have your accountant prepare the bridge first. Enter additions and deductions only once.
Keep capital spending visible
EBITDA is not money freely available to distribute. It does not subtract all cash needed for equipment replacement, debt service, working capital and taxes. A buyer may reasonably distinguish routine operating repairs from a major replacement project.
Provide a maintenance history and an estimate of near-term capital needs. If a conveyor, boiler, reclaim system or roof needs work, show the condition, quote and expected disruption. Do not hide the need behind an add-back or subtract the same repair twice in competing parts of a valuation model.
Example: read a repair bill alongside its reimbursement
Suppose a wash's reported EBITDA includes a $45,000 repair expense and $30,000 of related insurance income in the same period. If the parties support removing both as an unusual event for this earnings scenario, the net upward adjustment is $15,000: add the $45,000 expense and remove the $30,000 income. Adding $45,000 while keeping the insurance income overstates that adjustment by $30,000.
If the repair was capitalized instead of expensed, the $45,000 invoice does not establish a $45,000 EBITDA add-back. If a claim is unpaid or recorded in another period, reconcile the timing before using the same bridge. These examples explain accounting checks; they do not establish how a particular repair, tax deduction or insurance claim should be recorded.
After the adjustment discussion, keep the current condition visible. A documented past reimbursement does not answer whether the conveyor, pump or roof now needs further work. Give the buyer the service history and current quote, and identify where any remaining cost is addressed in the model or proposed terms.
Explain revenue quality and timing
Separate current operations from a forecast. A price increase may support a forward case, but the observed response, churn and wash volume matter. A signed contract or planned expansion should be identified by status rather than quietly folded into historical earnings.
Review prepaid memberships, gift cards, refunds, sales tax, cash sales and cutoff dates. A quality-of-earnings engagement can examine the sustainability and presentation of earnings in more detail; its scope should match the transaction. It is different from a valuation opinion and does not guarantee a closing.
Prepare the buyer discussion
- Which adjustments are supported by invoices or ledger detail?
- Which owner duties need replacement, and at what cost?
- Does the earnings figure include a realistic occupancy charge?
- Are revenue and expenses measured on consistent periods and accounting bases?
- What cash spending is required beyond EBITDA?
- Which items could a buyer reasonably dispute?
A smaller earnings figure with clear support may be more useful than an aggressive figure that unravels during diligence. Keep a version history so everyone can see why an assumption changed.
