The numbers
Plumbing business owner salary: how much do plumbing business owners make?
There is no official statistic for what plumbing business owners earn. What exists is the wage data for plumbers who work for someone else, and the arithmetic of your own business: revenue, minus costs, minus taxes. Here is both, with an example and the levers that move the result.

Search for what a plumbing business owner makes and you'll find confident numbers. Be careful with them. The government's wage statistics for plumbers leave owners out, and there's no official survey of what owners of small plumbing shops take home. Any single figure you read is an estimate from a private source, or a guess.
The honest answer has two parts: what plumbers earn as employees, which is the floor an owner should beat, and how an owner's income is actually built, which you can work out for your own shop. This guide covers both, with a worked example.
The short answer
A plumbing business owner makes what the business earns after its costs, minus the owner's taxes. Two owners with the same truck and the same skills can end the year tens of thousands of dollars apart, because of how they price, how many hours they bill and what they spend. The example further down shows how much each of those moves the result.
The employee baseline: BLS wage data
The U.S. Bureau of Labor Statistics (BLS) publishes pay for plumbers, pipefitters and steamfitters in its Occupational Outlook Handbook, using its Occupational Employment and Wage Statistics (OEWS) survey:
| BLS figure, May 2025 | Pay |
|---|---|
| Median annual wage, all plumbers, pipefitters and steamfitters | $63,800 |
| Median hourly wage | $30.67 |
| Lowest 10 percent earned less than | $44,150 |
| Highest 10 percent earned more than | $108,420 |
| Median in plumbing, heating and air-conditioning contractors | $63,010 |
Those are wages paid to employees. The BLS says the OEWS survey doesn't include the self-employed or owners and partners in unincorporated firms, and the handbook notes that its pay figures don't include pay for self-employed workers. Self-employed workers held 8% of the 510,600 jobs in the occupation in 2025, according to the same page.
So use these numbers as a baseline, not an answer. If your business can't pay you at least what you'd earn working for a shop down the road, plus something for the risk you carry, the business is the problem, not the market.
How owner income works
Owner income is built in three steps:
- Revenue: labor you bill, plus what you charge for materials.
- Minus costs: the materials you bought, and everything it takes to stay open: vehicle, insurance, tools, phone, software, marketing, any employees.
- Minus taxes: income tax, and Social Security and Medicare on what you earn.
How the money reaches your bank account, and how it's taxed, depends on how the business is set up. That's where the words draw and salary come from.
Sole proprietor: owner's draw
The IRS defines a sole proprietor as someone who owns an unincorporated business by themselves; a single-member LLC is usually taxed the same way unless it elects to be treated as a corporation. You don't pay yourself a wage. You take draws, money moved from the business account to your own, and you're taxed on the business's profit whether you draw it or not. The IRS lists the forms: Schedule C for the profit, Schedule SE for self-employment tax, and Form 1040-ES for estimated tax payments during the year.
Self-employment tax is the owner's version of payroll tax. The IRS sets the rate at 15.3%: 12.4% for Social Security and 2.9% for Medicare. It applies once net earnings from self-employment reach $400, and you can deduct the employer-equivalent portion when you figure your adjusted gross income. An employee has half of that paid by the employer. An owner pays both halves.
S corporation: a reasonable salary, then distributions
Some owners elect S corporation status. Then you work for your own company as an employee. The IRS says an S corporation must pay reasonable compensation to a shareholder-employee for the services they provide before it makes non-wage distributions to them. That salary goes through payroll, with withholding, on a W-2. Profit above it can be taken as distributions.
The IRS doesn't publish a number for reasonable compensation. It lists factors, including training and experience, duties and responsibilities, time and effort devoted to the business, what comparable businesses pay for similar services, and payments to non-shareholder employees. Whether an S corporation makes sense for you, and what salary to set, are questions for your accountant.
| Setup | How you get paid | Taxes on your pay |
|---|---|---|
| Sole proprietor (or single-member LLC taxed as one) | Owner's draws from the profit | Income tax and self-employment tax on the profit |
| S corporation | A reasonable W-2 salary, then distributions | Payroll taxes on the salary; income tax on salary and profit |
A worked example
Every number here is an example, chosen to match our pricing guide: a solo plumber charging $100 an hour, billing 1,400 hours a year, with $45,000 a year of business costs. We add an example materials line: $45,000 of parts sold at a 30% markup.
| Example line | Amount |
|---|---|
| Labor: 1,400 billable hours × $100 | $140,000 |
| Materials markup earned: $45,000 × 30% | $13,500 |
| Business costs (vehicle, insurance, tools, office) | −$45,000 |
| Owner income before taxes | $108,500 |
That $108,500 isn't take-home pay. As a sole proprietor, the owner pays income tax and self-employment tax on it, buys their own health insurance and retirement savings, and gets no paid vacation, because a week off is a week of zero billable hours. As an S corporation, part of it would be a salary through payroll and the rest a distribution, but the total profit is the same before taxes.
Now change one input at a time:
| Example scenario | Labor revenue | Owner income before taxes |
|---|---|---|
| 1,000 billable hours at $100 | $100,000 | $68,500 |
| 1,200 billable hours at $100 | $120,000 | $88,500 |
| 1,400 billable hours at $100 | $140,000 | $108,500 |
| 1,400 billable hours at $110 | $154,000 | $122,500 |
Business costs ($45,000) and materials markup ($13,500) are held the same in every row to keep the comparison simple.
Because the costs are mostly fixed, almost every extra dollar of revenue goes to the owner. Losing 400 billable hours, to drive time, callbacks and evenings spent writing quotes, takes the same owner from $108,500 to $68,500, close to the BLS employee median. A $10 rate increase over the same hours adds $14,000.
What raises owner pay
Pricing
The rate is the strongest lever, because a price increase costs you nothing to deliver. Build it from your real costs, your own pay and a profit margin, as in how to price plumbing jobs, and review it every year. When the numbers say it's time, our price increase letter guide covers notice and wording.
Billable hours
Every hour you work but can't bill is pay you don't get. Tighten your service area, batch supply house runs, charge for second trips, and cut the time you spend on paperwork. Track billable hours for a few normal weeks so you know your real number.
Average ticket
More revenue per visit means fewer visits for the same income. Offer options on every quote, a standard repair and a better one, and stop forgetting the items that belong on the job: the shutoff, the supply lines, the expansion tank, the permit, the haul-away. Each is small; together they're a real share of the year.
Memberships and maintenance agreements
A maintenance agreement, such as a yearly water heater flush and inspection, brings revenue in slow months and puts you first in line when something breaks. Price it from the same hourly cost as everything else, and keep its renewal and price terms in writing.
Costs
Review your costs once a year, line by line. Insurance, vehicle and software creep up quietly. A cost you cut adds to owner income dollar for dollar, the same as a sale.
Set your pay first, then your prices
The owners who end up paying themselves well usually decide what they need to earn before they set prices, not after. Put your own pay in the plan as a cost, work out the hours you can really bill, and let the rate follow. The one-page plumbing business plan walks through it, including how many jobs a week it takes.
Evenings spent writing quotes are hours you can't bill. Plumbo, now on the App Store and Google Play, builds a quote from a voice note and your own price book, gets it signed on your phone and turns it into an invoice in one tap. Try the 60-second demo →
