Seller's discretionary earnings (SDE) for an accounting practice

Seller’s discretionary earnings, or SDE, is an owner-operator earnings measure that generally includes one working owner’s compensation and supported discretionary items, after normalizing the business’s other continuing expenses.

What question does SDE answer for a practice buyer?

SDE estimates the earnings available before paying one working owner for both labor and invested capital. It is useful when that owner will personally operate the acquired practice.

That framing differs from profit after a hired manager and technical producer have been paid. A CPA buying their first firm may want to compare prospective owner income with employment income. An investor who will not prepare returns needs a replacement team instead. A single number cannot answer both questions without an explicit compensation bridge.

The IBBA Canada definition of discretionary earnings includes one owner-operator’s compensation and adjusts other owners to market compensation. This is a business-broker convention, not a promise that all reported owner benefits are unnecessary. Use the valuation hub to connect the earnings measure with price, financing, and transferable client relationships.

SDE does not guarantee a buyer’s take-home pay. Interest, principal repayments, personal taxes, reinvestment, and working-capital needs can consume substantial portions. A purchase model should distinguish compensation for working from the return earned on the purchase investment.

How is SDE calculated from the books?

Build it from reported income and a documented adjustment schedule. Identify the owner whose compensation is included and the duties that person must perform.

For an entity with wages deducted in the income statement, add back the selected working owner’s pay and qualifying benefits. For a sole proprietor, owner draws generally do not appear as business expenses, so adding the draws to Schedule C profit would double count earnings. The starting financial statement and tax classification determine the bridge, not a universal spreadsheet formula.

Interest, depreciation, and amortization may be separated to establish the conventional pre-financing measure. Income taxes require care: personal owner taxes and an entity’s recorded tax expense are not the same item. Unsupported additions for expenses never deducted from the starting profit make the result wrong even when the owner incurred those costs personally.

Remove nonoperating gains and normalize unusual activity in both directions. A refunded insurance premium can be as relevant as a one-time repair. Keep a column for the evidence, a column for recurrence, and a column showing whether the buyer agrees.

What expenses qualify as discretionary in the calculation?

An expense is discretionary for this purpose when the operation can continue without it and the expense was actually recorded. Buyer preferences alone do not establish an add-back.

A personally used vehicle, family travel, or an owner’s nonbusiness subscription might qualify after verifying its ledger treatment and business component. A professional subscription needed to prepare specialized returns does not become discretionary because the buyer dislikes that vendor. A spouse’s wages require a duty review: replacing bookkeeping or reception still costs money.

Ordinary security, malpractice coverage, licensing, training, and tax-season staffing should remain if the purchaser needs them. If the seller has postponed those costs, normalization may lower the apparent earnings. Deferred spending is often a future obligation rather than a benefit transferable to the buyer.

The IBBA income-approach explanation emphasizes matching the earnings measure with the valuation method. An owner-earnings multiple should not be applied to after-replacement earnings without understanding the mismatch. For the alternate lens, read adjusted EBITDA.

How does a numerical example separate labor from investment return?

Calculate conventional SDE, then subtract the buyer’s assumed labor cost and cash obligations. The following example uses invented inputs solely to illustrate the method.

The SDE math is $115,000 + $155,000 + $17,000 + $8,000 − $20,000 = $275,000. Subtracting assumed owner labor of $145,000 leaves $130,000 before acquisition debt and other cash requirements. If assumed annual debt payments are $88,000, the remaining amount is $42,000 before taxes, investment, and reserve changes.

A buyer calling the entire $275,000 an investment return counts compensation for preparing returns as ownership profit. Unpaid professional labor is not a sustainable valuation assumption.

How should a two-owner firm be treated?

Select one owner-operator for SDE and normalize the other owners’ continuing duties to market costs. Do not remove everyone’s compensation and leave the production plan empty.

Suppose one partner handles business tax and another oversees payroll and client service. The purchaser might replace the first partner personally but still need a manager for the second role. Review actual hours, specialties, seasonal peaks, and review authority. Neither equal ownership nor equal distributions proves that the work can be replaced at equal cost.

For each owner, list work that ends, work the purchaser assumes, and work transferred to staff or outside professionals. Estimate the compensation of those replacements and include benefits. If the buyer intends to add a second working owner, describe that as the buyer’s capital and labor arrangement rather than an automatic increase in SDE.

The book of business definition adds the service perimeter. Removing an entire service line can reduce both owner labor and client fees, so the SDE adjustment must change both sides of the model consistently.

What do sellers, buyers, and lenders need to see?

They need the same reproducible historic bridge, followed by audience-specific cash planning. A supported adjustment schedule is more useful than a persuasive earnings headline.

Sellers should retain receipts and explain personal or unusual expenses before presenting the number. Tax returns, monthly statements, and payroll reports should connect. If financial statements and returns differ, provide the basis reconciliation rather than expecting the buyer to accept whichever figure is higher.

Buyers should map the earnings claim to their own qualifications and availability. An EA buying tax work may have a different permissible service scope from a CPA acquiring an attest practice. Professional requirements and insurance need review before treating all historic revenue as work the buyer can perform.

The SBA 7(a) loan description recognizes ownership-change financing and cash-flow repayment. The lender still needs its own underwriting. Read fee realization to test whether recorded fees become cash; lenders cannot repay a loan with an uncollected owner-income estimate.

Which mistakes most often inflate SDE?

Double counting and missing replacement costs are the central errors. Check each adjustment against the starting statement and the future service plan.

1. Confirm that owner compensation was deducted before adding it back.
2. Remove only supported nonbusiness portions of mixed-use expenses.
3. Budget all duties performed by additional owners and unpaid family staff.
4. Exclude unusual income consistently with unusual expense adjustments.
5. Calculate a separate monthly cash plan after debt, taxes, and reinvestment.

Another error is presenting temporary understaffing as durable profit. If employees left late in the measurement year, payroll may have fallen while the remaining staff absorbed excessive hours. Review the service calendar and replacement hiring needs before accepting that margin. A practice that cannot complete engagements on time may lose the revenue supporting the earnings.

How can an owner-operator decide whether the economics work?

Compare the purchase with the buyer’s realistic alternative employment and capital use. The practice should support both a working income and a tolerable return for the risks assumed.

Ask how many annual hours the buyer must work, what busy-season coverage exists, and what happens during illness or vacation. Model a second preparer if the promised lifestyle depends on one. A higher owner draw earned through longer hours is not automatically a better acquisition.

Then test a reduced-revenue case while keeping necessary staff and overhead. Client loss may arrive before expenses can shrink. Preserve liquidity for that period and avoid using every available dollar for the down payment. SDE works best as an organized starting point for these questions, with labor, capital return, and available cash displayed separately.
