DE First, Then the Multiple

Business value comes from your Seller’s Discretionary Earnings (SDE) and the multiple a buyer applies.

SDE starts with net profit and adds back owner compensation, eligible owner perks, interest, depreciation and amortization, and legitimate one-time costs. The multiple reflects the quality of those earnings. For plumbing businesses, recurring service revenue, maintenance agreements, lower owner dependence, and clean financial records can support a stronger multiple.

How To Value Plumbing Business

Use the calculator above, or run it yourself. For many smaller owner-operated businesses, buyers commonly use SDE as the earnings measure and apply a market-based multiple. Get these steps right.

1. Start with net profit. Use the pre-tax net profit from a clean P&L.
2. Add back eligible owner compensation. Include owner salary and other qualifying compensation that may be added back under the valuation methodology.
3. Add back eligible owner perks. Include qualifying personal expenses such as vehicle, insurance, or travel run through the business.
4. Add back interest, D&A, and one-time costs. Include financing costs, depreciation and amortization, and legitimate non-recurring expenses.
5. Calculate your SDE. These adjusted earnings represent the owner's economic benefit and provide the basis for the valuation.
6. Apply a plumbing multiple. Choose a multiple based on recurring service revenue, owner dependence, financial quality, customer concentration, and buyer type.

What Goes into the Valuation

A business valuation for an owner-operated service business typically includes:

Net profit

Your pre-tax bottom line and the starting point for calculating SDE.

Owner's compensation

Eligible owner compensation that may be added back when calculating SDE, depending on the valuation methodology.

Owner perks

Eligible personal expenses such as a vehicle, insurance, or travel run through the business.

Interest, depreciation & amortization

Applicable financing costs and non-cash accounting expenses that may be added back when calculating SDE.

One-time expenses

Non-recurring costs that a new owner is not expected to repeat.

The multiple

What buyers pay for each $1 of SDE, influenced by recurring service revenue, owner dependence, customer concentration, financial records, and crew retention.

Frequently Asked Questions

SDE, or Seller's Discretionary Earnings, is your net profit plus expenses and benefits a new owner would not inherit, such as owner compensation, eligible personal expenses, interest, depreciation, amortization, and one-time costs. Buyers use SDE because it shows the economic benefit available to a new owner-operator. Net profit alone does not provide the same comparison because it includes the current owner's compensation and other expenses that may change after a sale.

For many owner-operated businesses under roughly $3M in revenue, SDE is commonly used because the buyer may be taking over the owner's operating role. At larger businesses with an established management team, buyers may use EBITDA because those management costs continue after the sale. The crossover is not rigid, and the appropriate earnings measure depends on the business and buyer. This calculator uses the SDE method.
