Revenue Per Plumber: What's a Healthy Benchmark?

Revenue per plumber is one of the few numbers that tells you something about your entire operation in a single figure. It captures how effectively you convert your scarcest and most expensive resource, licensed skilled labor, into revenue.

A plumbing business generating strong revenue per plumber is pricing well, dispatching efficiently, and keeping its people on productive work.

A business with weak revenue per plumber is losing money somewhere, and the number itself won't tell you where, but it will tell you to go looking.

This post covers what revenue per plumber measures, what healthy benchmarks look like, how to calculate it correctly, and what to do when the number comes in below where it should be.

What the number actually measures

Revenue per plumber is your total revenue divided by the number of revenue-producing plumbers you employ, usually expressed annually. It's a productivity measure, but more precisely it measures how well your business model converts licensed labor into dollars.

This matters more in plumbing than in most trades because licensed plumbers are genuinely hard to find and expensive to keep. Your growth is constrained by how many qualified people you can hire and retain, which means the revenue each one generates is close to the ceiling on what your business can do.

Two plumbing companies with four plumbers each can produce wildly different revenue depending on how they price, how they schedule, and what mix of work they take.

Revenue per plumber compresses all of that into one comparable number.

It's also a useful early warning.

Revenue can grow while revenue per plumber falls, which happens when you're adding headcount faster than you're adding productive work.

That looks like growth on the top line and feels like growth day to day, but it's actually margin compression in progress, and revenue per plumber catches it before the P&L does.

What a healthy benchmark looks like

Revenue per plumber varies substantially based on your work mix, your market, and how you count people, but there are ranges worth measuring against.

For a residential service and repair plumbing business, revenue per plumber commonly lands somewhere in the range of $180,000 to $300,000 annually, with strong operators pushing higher.

Service work is labor-intensive with modest material content, so the revenue per hour of plumber time is lower than on larger jobs, but the margins are better, which is why service-heavy businesses can run lower revenue per plumber while still being more profitable than their new construction counterparts.

For businesses weighted toward repipes, sewer and drain work, and larger residential projects, revenue per plumber tends to run higher, often $250,000 to $400,000, because those jobs carry more revenue per day of labor even though the margin percentage is typically thinner.

For new construction plumbing, revenue per plumber can run higher still on a raw basis, since rough-in work moves fast and job values are large, but the margin per revenue dollar is the lowest of the three categories. A high revenue per plumber in a new construction shop doesn't automatically mean the business is more profitable than a service shop with a lower number.

How you count plumbers changes the figure meaningfully. Counting only licensed plumbers who independently produce billable work gives you a higher number than counting apprentices and helpers who support the work without independently generating it.

Neither approach is wrong, but you have to pick one and apply it consistently, and you should be careful comparing your number to an industry benchmark that may count differently than you do.

What matters more than hitting a specific number is your own trend and whether you understand what's driving it. A business at $210,000 per plumber that knows exactly why and is improving year over year is in better shape than one at $290,000 that has no idea what's behind the figure.

How to calculate it correctly

The math is simple, but a few decisions determine whether the output is useful.

Decide what revenue to count. Total revenue is the standard, but if a meaningful share of your revenue is high-cost fixtures and equipment flowing through at modest markup, you may also want to track gross profit per plumber alongside revenue per plumber. Gross profit per plumber strips out the pass-through effect of expensive water heaters and fixtures and shows you the value each person is actually generating.

Decide who counts. The cleanest approach for most businesses is counting licensed plumbers producing billable work, treating apprentices and helpers separately since they support production rather than driving it. If you run two-person crews on larger jobs, you need a consistent convention so the number stays comparable across periods.

Decide the time period. Annual is standard for benchmarking, but tracking monthly or quarterly surfaces patterns you'd otherwise miss. In Florida, that matters because plumbing demand has real seasonal texture even though it's steadier than HVAC. Rainy season drives drain and sewer work, hurricane recovery produces bursts of emergency and repair volume, and new construction follows the building cycle rather than the weather.

Monthly tracking shows you whether productivity holds through those swings.

The inputs come straight from your books, which is where this gets difficult for businesses with messy financials. If your revenue is organized by work type and your payroll cleanly distinguishes licensed plumbers from helpers from office staff, the calculation takes two minutes. If it isn't, the number becomes an estimate built on other estimates.

What a low number is telling you

When revenue per plumber comes in below where it should be, the cause is usually one of four things, and each points somewhere different.

Underpricing is the most common. If your plumbers are busy, the schedule is full, and revenue per plumber is still weak, you're almost certainly charging too little. This is endemic in plumbing, where owners underprice service calls out of fear that customers will balk, and the result is a team that's working constantly without generating proportionate revenue.

Dispatch and scheduling inefficiency is second. Time spent driving between distant jobs, waiting on parts, or sitting between calls is time that produces nothing. In a service business where jobs are short, drive time can consume an enormous share of the day, and tight routing is one of the most direct levers available.

Non-billable time is related but distinct. Callbacks, warranty work, shop time, training, and administrative tasks all consume plumber hours without generating revenue. Some is necessary. When it grows past that, it shows up here first.

Work mix is fourth. A business doing nothing but small service calls will show lower revenue per plumber than one with a mix that includes repipes, water heater replacements, and larger projects. If your number is low and your mix is entirely low-ticket work, the path forward may be developing higher-value work rather than squeezing more efficiency out of the existing schedule.

What a high number is telling you

High revenue per plumber is usually good, but it's worth understanding the cause, because not every high number is healthy.

If it's high because you price well, schedule tightly, and have a strong work mix, that's a well-run business. If it's high because your plumbers are working constant overtime and heading toward burnout, the number is hiding a retention problem that will surface as turnover, and replacing a licensed plumber is expensive and slow. If it's high because you're understaffed relative to demand and turning work away, then the number is actually telling you that you're leaving revenue on the table by not hiring.

Read it alongside your overtime hours, your retention, and whether you're declining work. High revenue per plumber with stable staffing and reasonable hours is excellent. The same number with heavy overtime and turnover is a warning.

Where this connects to your books

Like every benchmark, revenue per plumber is only as reliable as the data underneath it, and acting on it requires more than the number itself. You can't tell whether a low figure comes from underpricing or from inefficiency without job costing that shows you margin and labor hours by job.

You can't track it consistently without books that separate revenue by work type and payroll that distinguishes licensed plumbers from support staff. And you can't tell whether a pricing change or a scheduling change actually worked without the financial visibility to watch the number move.

That's the pattern across all of these benchmarks. The metric is simple. Producing it honestly and acting on it intelligently both depend on the financial structure underneath, which is why the businesses that actually use these numbers to improve are the ones whose books were built to support them.
