How much do plumbing business owners make? The arithmetic

How much plumbing business owners make depends on which owner you mean. On our worked model a solo owner running about 2.2 billed calls a day keeps roughly $91,748 a year before tax, which is about $43 for every hour actually worked. An employed plumber on the same model takes $62,400. And an owner who adds one employed plumber and a second van, at the same fill rate, keeps about $84,832, less than they did working alone.

This is written for a plumber who owns a business or is about to. We build the software that small local trades run their bookings, deposits and rebooking on, so treat this as our view rather than neutral advice. Every figure below is our own arithmetic on a model we state, and none of it is a borrowed average. Put your own invoice, calls and wages in and re-run it.

All figures are in US dollars as a reference point. The arithmetic works in any currency. None of this is tax or legal advice.

How much do plumbing business owners make per hour, day, week, month and year?

The model, stated so you can argue with it. It is the same one we used in how to start a plumbing business, so the two posts add up. An average invoice of $260 (a $95 call out plus an hour and a half at $110). Parts at 22% of revenue. $13,100 a year of fixed costs for the van, liability cover, licence renewal, software and marketing. 235 working days, which is 47 weeks of five. A diary that averages 2.2 billed calls a day, because three days are full and two have gaps. And a 45 hour working week for the owner, evenings of quoting and invoicing included.

The employed plumber is paid for every hour in that column, holidays included. The two owners are not, so their hourly figure is income divided by every hour worked, the unbilled ones too.

Before going further, two checks that the model reproduces page one. The US government's occupational wage data puts the median plumber at $30.67 an hour and $63,800 a year for May 2025, against our $30 and $62,400. And the range most pages on this search quote for owners is $70,000 to $120,000, which our solo figure sits inside. So neither column is in dispute. What follows is the part those pages leave out.

Why you charge $110 an hour and keep $43

The gap between those two numbers can be walked down in three steps.

The first drop is the big one. At 2.2 calls a day you are on site for about 3.3 of your nine hours. The rest is driving, writing up, quoting, the merchant counter and the gap where a call cancelled. We priced the merchant run separately in the plumbing startup post.

One empty slot a week shows how much the fill rate matters. Forty seven lost calls at $260, less parts, is $9,532 of contribution gone in a year, at no change in price.

Does a second van make the owner more money?

This is the question the salary pages do not touch, and the answer surprised us the same way it did when we ran it for landscaping crews.

A second van with an employed plumber costs about $92,700 a year before it earns anything. That is $62,400 of wages, about $15,600 of payroll taxes, cover and other on costs, $13,200 to run and finance the van, and $1,500 of extra software, phone and insurance. Meanwhile the owner's own billed calls drop from 2.2 to about 1.8 a day, because someone has to quote, dispatch and take the callback.

Every billed call a day, across a year, is worth $47,658 of contribution after parts. So the second van's result depends entirely on how full its diary is.

Working alone returns $91,748. At 2.2 calls the second van leaves you $6,916 worse off. Below about two calls a day it loses money outright. It only beats working alone at about 2.35 billed calls a day, which is a little over seven calls every three days.

So a second van is a capacity decision first, and it turns into income only once there is enough booked work to fill it. The work that fills it most reliably is the work that repeats. Water heater flushes, backflow tests and annual boiler services come round on a known interval, and a customer who is reminded when they fall due books again instead of phoning whoever is top of the search.

Can plumbers make 200K a year?

Owners can, but rarely by working harder alone. At a $260 average invoice, three calls a day, every working day, a solo owner tops out near $129,874 before tax. There are two ways past that ceiling.

1. Raise the average invoice. Clearing $200,000 solo at three calls a day needs an average invoice of about $388. In practice that comes from installs and replacements mixed into the service work, not from a higher hourly rate on the same calls.
2. Add vans that are close to full. Two technicians each at three calls a day, with you still billing 1.8, comes to about $173,232. Each van at three calls adds about $50,274. Each van at two calls adds $2,616.

The second route gets there, but only with full diaries. A half booked van is roughly a wash.

How much should a plumbing business owner pay themselves?

The Facebook thread on page one asks this in the owner's own words, including how to balance paying yourself against growing the company. Our view is to separate the two.

Take a fixed monthly draw equal to what you would earn employed. On our model that is about $5,200 a month, or $62,400 a year. Treat the other $29,348 as the return for carrying the risk, and spend it in order. Money set aside for tax first, then the replacement van, then a reserve for a slow quarter, and only then a second van or yourself. A before tax figure is not a salary, and the owners who get into trouble are usually the ones who spent it as one.

Why are plumbers the new millionaires?

The plumber holding the wrench is not the millionaire in that headline. The owner of a firm with several vans and a customer base somebody else would buy is.

A buyer pays for revenue that keeps arriving after you leave. That means repeat customers on a known schedule, a job history per address, and reviews under the business name rather than yours. A business whose customer list lives in the owner's phone contacts is very hard to sell, however busy it is. That is the part of the business our software holds. Every booking builds a customer record with its visit history and notes, and recurring visits put the next service on a clock instead of in your memory.

Is plumbing a profitable business?

Yes. On our numbers a solo owner out earns the employed plumber by about $29,000 a year. The risk sits in the share of the working week you bill, and it compounds once there is a wage to cover. The startup post works out the $617 a day it takes to clear $100,000, which we would read before deciding on a second van.

We are not publishing a table by region. What moves income is the average invoice, the calls you bill a day, and whether each van you pay for has a full diary.

What we do, and what we do not

Every number above starts with two inputs, what a job is priced at and how long it really takes. We would start by putting a price and an honest duration behind each service, which is what managing your services covers.

That is one of the live storefronts we run. It is an auto repair shop, not a plumber, and we would rather say so than show a mockup. We have no plumbing demo yet. It uses the same job and work order shape plumbing needs, and you can see an itemized estimate the customer approves before the work starts. The other live sites are on our portfolio.

The limits, said plainly.

• Our reminders go out by email. Bookings, confirmations and rebooking reminders all land in the customer's inbox.
• We do not run payroll. Every wage and on cost figure above is yours to work out, not something our software calculates.
• The revenue figure on your dashboard counts payments taken through Growth Onward. Cash or your own card reader does not appear in it, which understanding your revenue says too. If you want deposits on installs, how you charge is a setting.

The short version

A solo plumbing business owner on our model keeps about $91,748 a year before tax, or $43 an hour actually worked, against $62,400 for the employed plumber. A second van at the same fill rate pays the owner less, $84,832, and only overtakes working alone at about 2.35 billed calls a day.

The same arithmetic in other trades is in how much dog groomers make, how much car detailers make and how to start a handyman business. The wider argument, that the margin sits in the booked diary and repeat customers rather than the rate card, is in how local service businesses get and keep customers. More on this trade is on the plumbing hub, and the money side of every trade we cover is under pricing and payments.
