Plumber pay in Missouri, bottom to top
BLS counts plumbers, pipefitters and steamfitters as one group, so the figures include industrial pipe work as well as service and new construction plumbing.
| Pay level | Hourly | Yearly | National hourly |
|---|---|---|---|
| 10th percentile | $21.53 | $44,780 | $21.22 |
| 25th percentile | $24.35 | $50,640 | $24.13 |
| Median | $32.11 | $66,790 | $30.67 |
| 75th percentile | $48.19 | $100,240 | $40.92 |
| 90th percentile | $56.34 | $117,180 | $52.13 |
| Average (mean) | $36.06 | $75,010 | $34.70 |
From the bottom tenth ($21.53) to the top tenth ($56.34), the top of the scale pays about 2.6 times the bottom in Missouri, close to the 2.5 times spread for plumbers nationwide.
Both ends of the scale beat the national figures: $21.53 against $21.22 at the bottom tenth, and $56.34 against $52.13 at the top.
The average wage, $36.06, sits 12% above the median. A smaller group of higher earners pulls the average up, so the median is the better guide to what a typical plumber makes.

What a plumbing business in Missouri should charge
Say you run a plumbing business in Missouri and pay the state median of $32.11 an hour. Here is the labor rate calculator's math on its starting numbers: 40-hour weeks, 10 paid days off, 2 unbilled hours a day, 7.65% payroll taxes, $90,000 a year of overhead and 15% profit.
| Step | Math | Result |
|---|---|---|
| Paid hours | 40 × 52 | 2,080 |
| Hours at work | 2,080 − 10 days × 8 | 2,000 |
| Billable hours | 2,000 × 6 ÷ 8 | 1,500 |
| Labor cost | $32.11 × 2,080 × 1.0765 | $71,898 |
| Break-even rate | ($71,898 + $90,000) ÷ 1,500 | $107.93 |
| Rate with 15% profit | $107.93 ÷ 0.85 | $126.98 |
That is $126.98 per billable hour, 4 times the wage, and $2.53 more than the $124.45 the same math gives at the national median wage.
Paying the 75th percentile instead, $48.19 in Missouri, to hire and keep experienced people raises the rate to $155.22.
A cheaper crew saves less than it seems: at the 25th percentile wage of $24.35, the rate only drops to $113.35.
Overhead, at $60 of every billed hour, and the unbilled hours move this rate more than a raise does. A dollar more in wages adds about $1.76 to the rate.
