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.
