Janitor pay in Washington, bottom to top
BLS counts janitors and cleaners together, outside of maids and housekeeping. Office cleaning crews and school custodians are in this group.
| Pay level | Hourly | Yearly | National hourly |
|---|---|---|---|
| 10th percentile | $17.82 | $37,070 | $13.77 |
| 25th percentile | $18.76 | $39,020 | $15.50 |
| Median | $21.89 | $45,520 | $17.71 |
| 75th percentile | $25.93 | $53,920 | $21.18 |
| 90th percentile | $29.58 | $61,520 | $24.17 |
| Average (mean) | $22.79 | $47,410 | $18.64 |
From the bottom tenth ($17.82) to the top tenth ($29.58), the top of the scale pays about 1.7 times the bottom in Washington, close to the 1.8 times spread for janitors nationwide.
Both ends of the scale beat the national figures: $17.82 against $13.77 at the bottom tenth, and $29.58 against $24.17 at the top.
The average, $22.79, is close to the median, so pay sits fairly evenly around the middle.

What a commercial cleaning company in Washington should charge
Higher wages in Washington go straight into the price. Take a commercial cleaning company in Washington paying the state median of $21.89 and run it through the labor rate calculator with 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 | $21.89 × 2,080 × 1.0765 | $49,014 |
| Break-even rate | ($49,014 + $90,000) ÷ 1,500 | $92.68 |
| Rate with 15% profit | $92.68 ÷ 0.85 | $109.03 |
That is $109.03 per billable hour, 5 times the wage, and $7.34 more than the $101.69 the same math gives at the national median wage.
Paying the 75th percentile instead, $25.93 in Washington, to hire and keep experienced people raises the rate to $116.13.
A cheaper crew saves less than it seems: at the 25th percentile wage of $18.76, the rate only drops to $103.53.
At this wage, overhead is most of the price: $60 of every billed hour goes to it before anyone is paid. Spreading the same overhead over more billable hours, with a second person or less drive time, brings the rate down fastest.
