Pricing plumbing work is one of the hardest parts of running your own shop. Charge too little and you're working yourself to death for nothing. Charge too much and you lose jobs to the guy down the street.
This guide breaks down the two main pricing models, gives you real formulas you can use today, and helps you figure out what your time is actually worth.
There are two ways to price plumbing jobs. Both work. The right choice depends on how you run your business.
You charge for the time you spend on the job, plus materials. This is straightforward and honest, but it has a major downside: the better you get at your trade, the less you make. A job that used to take you 3 hours now takes you 1 — and you earn two-thirds less for the same work.
Hourly works best for:
You charge a fixed price for the job, regardless of how long it takes. The customer knows the total upfront — no surprises. And you're rewarded for being efficient: finish faster, make more per hour.
Flat rate works best for:
Our take: If you're a solo plumber doing residential service calls, flat rate pricing will make you more money and close more jobs. Customers don't want to watch the clock while you work. They want a number they can say yes or no to.
Whether you price flat rate or hourly, you need to know what your time costs. Here's how to figure that out.
Annual overhead = truck payment + insurance + tools + licensing + gas + phone + software + everything elseBillable hours/year = (working days × hours per day) × 0.65Hourly rate = (desired salary + annual overhead + profit margin) ÷ billable hours
Say you want to make $80,000/year. Your overhead is $30,000/year. You want a 15% profit margin (money that stays in the business).
You work 250 days/year, 8 hours/day, billing 65% of your time. That's about 1,300 billable hours.
($80,000 + $30,000 + $16,500) ÷ 1,300 = $97/hour
So your minimum hourly rate should be around $95-100/hour. In most U.S. markets, that's reasonable for a licensed plumber.
Once you know your hourly rate, you can build flat rate prices for common jobs:
Flat rate price = (estimated time × hourly rate) + (materials × markup) + complexity buffer
Standard material markup in plumbing is 25-50%. This covers your time sourcing parts, your supply house account, and the risk of returns. A $200 water heater gets marked up to $250-300.
Don't feel guilty about markup. You're not selling parts — you're selling the knowledge of which parts to buy, the truck to carry them, and the license to install them.
Add 10-20% to your flat rate for jobs that might go sideways. Old houses, cast iron pipes, previous DIY work — these are all reasons to pad the price. Better to come in under budget than to eat the cost of an extra 2 hours.
These are the mistakes we see most often from solo plumbers and small shops:
You don't know their overhead, their skill level, or whether they're actually making money. Price based on your costs and your desired income. If you're losing jobs on price, the answer usually isn't to charge less — it's to sell the value better.
If you drive to a house, spend 30 minutes figuring out the problem, and then give a free estimate, you just donated an hour of work. Charge a service call fee ($75-150). Apply it to the job if they hire you. This filters out tire-kickers and pays you for your expertise.
The customer isn't paying for 20 minutes. They're paying for the 20 years it took you to learn how to fix it in 20 minutes. They're paying for the truck, the tools, the license, and the guarantee. Don't discount your price because the job was easy for you.
Your costs go up every year. Gas, insurance, parts, everything. If you don't raise your prices at least 3-5% per year, you're giving yourself a pay cut. Review your rates every January.
Pricing confidence comes through in how you present the number. A few tips:

These prices assume a licensed plumber with insurance in a mid-cost market. Urban areas and high-cost-of-living markets will be higher.
Know your costs. Set your rate. Present it with confidence. And put it in writing.
The plumbers who make the best money aren't the ones who charge the most — they're the ones who know exactly what their time is worth, price accordingly, and don't apologize for it.
