What Should a Plumbing Pro Charge Per Hour?

Ask ten plumbers what they charge per hour and you will get ten different answers, and most of them are guesses. Some picked a number that sounded fair. Some copied the shop down the road. A few landed on a rate years ago and never touched it while fuel, insurance, and parts kept climbing. The problem with all three approaches is the same: they start from a number instead of from what the business actually needs to survive and pay you. This post walks through how to build a plumbing hourly rate from the ground up, starting with the income you want and working backwards through real hours and real overhead.

Start With the Paycheck, Not the Price

Most pricing advice runs in the wrong direction. It asks "what should I charge?" when the real question is "what do I need to earn, and what has to be true about my rate to get there?" Flip it around. Decide what you want to take home for the year as an owner-operator or what you want your crew to clear, then add everything the business must pay before a dollar reaches your pocket.

Write down three numbers to begin: the annual income you want, your yearly overhead (the cost of simply existing as a business), and the number of hours you can actually bill a customer for. Those three numbers drive everything. Change any one of them and your rate changes with it.

Billable Hours Are Not Working Hours

Here is where a lot of shops lose money without realizing it. You might work 2,000 hours a year, but you cannot bill all of them. Driving between jobs, quoting, picking up parts, truck maintenance, invoicing, chasing payments, answering the phone, and the inevitable dead time all eat into the day. For many field plumbers, actual billable time lands somewhere in the range of 50 to 65 percent of hours worked.

If you assume you bill every hour, you will set your rate too low and quietly give away the overhead and admin time for free. So before you divide anything, be honest about how many hours a year truly show up on an invoice.

Overhead Is in the Rate Whether You Like It or Not

Overhead is every cost that keeps the business running regardless of which job you are on. If you do not build it into your rate, it comes straight out of your income. Common line items include:

• Truck payments, fuel, and maintenance
• General liability and vehicle insurance
• Licensing, bonding, and permits
• Phone, software, and payment processing fees
• Tools, equipment, and replacement
• Advertising and lead costs
• Admin or dispatch help, even if that is just you after hours
• An emergency and slow-season buffer

Add these up for the year. This is the number your billable hours have to recover on top of your target income. Skip it and you are essentially funding your own business out of your wages.

A Worked Example You Can Copy

Numbers make this concrete. These are illustrative, so plug in your own, but the structure holds for a solo plumber or a one-truck operation.

1. Target take-home income: $85,000 for the year.
2. Annual overhead: $55,000 (truck, insurance, software, fuel, tools, marketing, buffer).
3. Total the business must generate: $85,000 + $55,000 = $140,000.
4. Hours worked per year: roughly 2,000 (40 hours over 50 weeks).
5. Billable portion at 55 percent: about 1,100 billable hours.
6. Required rate: $140,000 divided by 1,100 = about $127 per hour.

That $127 might feel high if you have been charging $85. But notice what happens if you ignored overhead and divided $85,000 by 2,000 hours: you land near $43 and go broke slowly. The gap between those two numbers is exactly why so many busy plumbers feel like they are working constantly and still falling behind.

Now stress-test it. If your billable share is only 50 percent, your rate climbs toward $140. If you can push billable time to 60 percent through tighter scheduling, it drops toward $117. Small changes in efficiency move your rate a lot, which is why operations and pricing are the same conversation.

Why Copying a Competitor's Rate Loses Money

When you copy the plumber across town, you inherit numbers you cannot see. You do not know their overhead, their truck count, their crew size, their close rate, or whether their number is even working for them. Maybe they are undercharging and running on fumes. Maybe they have paid off their trucks and can afford a lower rate you cannot match. Maybe they are quietly going out of business.

Your rate is a reflection of your cost structure, not theirs. Two plumbers in the same ZIP code can and should charge differently if their overhead and income goals differ. Use competitor rates as a sanity check for your market, not as the source of your number. If your math lands well above everyone else, dig into why your overhead is heavier or your billable hours are lower, and fix that instead of just discounting.

Think in Ranges and Revisit Often

A single fixed rate is fragile. Build a range instead. You might carry a standard service rate, a lower rate for large or repeat commercial work that keeps your trucks full, and a premium rate for after-hours and emergency calls that interrupt your life. The core calculation stays the same, but you flex the number based on job type, risk, and how badly the customer needs you right now.

Then revisit the whole thing at least once a year, and sooner if fuel spikes, insurance jumps, or you add a truck. Your rate is not a tattoo. It is a dial you adjust as costs move, and the shops that protect their margin are the ones that recalculate on purpose rather than reacting after a bad quarter.

Putting It All Together

The right rate is not the one that feels comfortable or the one your competitor posts. It is the one that covers your overhead, respects your unbillable hours, and leaves the income you set out to earn. Run the three numbers, be honest about billable time, and treat your rate as a living figure. Do that and you stop guessing and start pricing like a business that intends to be around in ten years.
