Janitor pay in Wisconsin, 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 | $14.23 | $29,600 | $13.77 |
| 25th percentile | $16.53 | $34,370 | $15.50 |
| Median | $17.79 | $37,000 | $17.71 |
| 75th percentile | $21.19 | $44,080 | $21.18 |
| 90th percentile | $22.88 | $47,580 | $24.17 |
| Average (mean) | $18.53 | $38,550 | $18.64 |
Pay is bunched up in Wisconsin. The top tenth earn $22.88 an hour or more, about 1.6 times the $14.23 at the bottom tenth. Nationally that gap is 1.8 times, so the step from the bottom of the scale to the top is shorter here than in most places.
The floor is higher than nationally ($14.23 against $13.77) but the ceiling is lower ($22.88 against $24.17), which squeezes pay toward the middle.
The average, $18.53, is close to the median, so pay sits fairly evenly around the middle.
How Wisconsin compares with other states

Against its neighboring states, Wisconsin is in the middle: Illinois and Minnesota pay more, and Iowa and Michigan pay less.
How many janitors work in Wisconsin
About 45,640 janitors work on payrolls in Wisconsin, 2.1% of the 2,209,760 nationwide, the 16th largest count among the states.
That is 15.5 of every 1,000 jobs in Wisconsin, close to the trade's share of jobs nationally.
What a commercial cleaning company in Wisconsin should charge
Say you run a commercial cleaning company in Wisconsin and pay the state median of $17.79 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 | $17.79 × 2,080 × 1.0765 | $39,834 |
| Break-even rate | ($39,834 + $90,000) ÷ 1,500 | $86.56 |
| Rate with 15% profit | $86.56 ÷ 0.85 | $101.83 |
That is $101.83 per billable hour, 5.7 times the wage, and almost the same as the $101.69 the same math gives at the national median wage.
Paying the 75th percentile instead, $21.19 in Wisconsin, to hire and keep experienced people raises the rate to $107.80.
A cheaper crew saves less than it seems: at the 25th percentile wage of $16.53, the rate only drops to $99.62.
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.
