If you're building a real pool service company or swim school, not just a job you do yourself, its resale value is worth understanding well before you're ready to sell. The math is more approachable than it sounds, and it's the same math a serious buyer will use whether you like it or not — better to know it in advance.
The formula buyers actually use
Most buyers price a small service business as a multiple of its owner's profit. Not revenue — profit, and specifically a version of profit called owner's profit (sometimes called seller's discretionary earnings). Revenue tells a buyer how big you are; owner's profit tells them how much money the business actually generates for whoever owns it.
The multiple itself isn't fixed. It depends on the size of the business, how risky it looks, and your local market, and a business broker who works with service businesses can tell you what's realistic for yours. In pool service specifically, individual routes are also commonly bought and sold on their own, and those deals are often priced against the route's recurring monthly billing rather than annual profit.
What counts as "owner's profit"
Owner's profit isn't just what's left on your P&L at the end of the year. It includes your own salary, any distributions or bonuses you've paid yourself, and personal expenses that run through the business — a truck, a phone plan, anything a new owner wouldn't actually need to keep paying for.
Adding all of that back on top of your bottom-line profit is called building an add-back schedule. It's standard practice in small business sales, and it's what turns your tax-return profit (often modest, on purpose) into the number a buyer uses to value the business.
Putting it together
Here's an illustrative example, not a benchmark. Say your business shows $90,000 in profit on paper. You also pay yourself a $60,000 salary and run about $12,000 a year in truck and phone costs through the company. Your add-back schedule brings owner's profit to $162,000. At a 2x multiple, that's a business worth about $324,000; at 3x, about $486,000. Where yours actually lands depends on the factors below.
Why a range, not a single number
- How much of your revenue is recurring — weekly service accounts and ongoing lesson enrollment are worth more than one-off repairs or drop-in classes
- Whether the business runs without you personally on every route or in every lesson
- How documented your systems are — route sheets, chemical logs, lesson curriculum, scheduling, staff onboarding
- Staff stability and credentials — certified technicians and instructors who stay are worth more than a team a new owner would have to rebuild
- How concentrated your revenue is — a few large commercial accounts are riskier than a broad customer base
- How seasonal your revenue is, and what you do to smooth it out
- Your compliance and safety record — current insurance, required licenses, and certifications
How PWSAC fits in
The things accreditation is built around — current, dated verification of your insurance and credentials, a real review history, and a public page customers can find you through — touch the same numbers a buyer will eventually look at. Growing your business isn't just about this year's income; it shapes what you can eventually sell it for.
