How much is a plumbing business worth?
Most owner-operator home-service businesses sell for a multiple of their Seller’s Discretionary Earnings (SDE) — net profit plus the owner’s salary and other add-backs. Small plumbing shops typically trade around 2×–3.5× SDE, with the exact multiple driven by how much recurring maintenance revenue you have, whether the business runs without you, how long you’ve been established, and whether revenue is growing.
This calculator uses the SDE method brokers apply to owner-operator shops: it builds your SDE, starts from a trade-specific base multiple anchored to real small-business transaction data, and adjusts it up or down for your value drivers before returning a likely price range. It also shows a rough revenue-multiple cross-check. Larger, team-run companies are usually valued on EBITDA at higher multiples — a different method this tool notes but doesn’t model. Treat the result as a starting point, then get a formal broker or M&A valuation before you buy or sell.

How do I value a plumbing business?
Start with Seller’s Discretionary Earnings: net profit + the owner’s salary + add-backs (interest, taxes, depreciation, and personal/one-time expenses). Multiply SDE by an industry multiple — typically 2×–3.5× for a small owner-operator shop. Example: $250,000 SDE at 2.8× is about $700,000. Recurring revenue, low owner dependence, and growth push the multiple higher.
What is SDE and how is it different from EBITDA?
SDE (Seller’s Discretionary Earnings) is net profit plus one owner’s compensation and discretionary add-backs — it reflects the total benefit to a single owner-operator, so it’s used for smaller shops. EBITDA does not add back owner pay, because it assumes a hired manager runs the company; it’s used for larger, team-run businesses and usually carries a higher multiple.
What increases the value of a home-service business?
Recurring maintenance-agreement revenue is the biggest lever — 40%+ of revenue on service plans can add half a multiple or more. A business that runs without the owner, a longer track record, healthy margins, and steady growth all raise the multiple. Heavy owner dependence, declining revenue, and thin margins lower it.
