What a plumbing business in North Dakota should charge
Say you run a plumbing business in North Dakota and pay the state median of $30.56 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 | $30.56 × 2,080 × 1.0765 | $68,428 |
| Break-even rate | ($68,428 + $90,000) ÷ 1,500 | $105.62 |
| Rate with 15% profit | $105.62 ÷ 0.85 | $124.26 |
That is $124.26 per billable hour, 4.1 times the wage, and almost the same as the $124.45 the same math gives at the national median wage.
Paying the 75th percentile instead, $36.95 in North Dakota, to hire and keep experienced people raises the rate to $135.48.
A cheaper crew saves less than it seems: at the 25th percentile wage of $23.92, the rate only drops to $112.60.
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.
