Janitor pay in Idaho, 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 | $13.65 | $28,390 | $13.77 |
| 25th percentile | $15.50 | $32,240 | $15.50 |
| Median | $17.36 | $36,110 | $17.71 |
| 75th percentile | $19.00 | $39,520 | $21.18 |
| 90th percentile | $23.56 | $49,000 | $24.17 |
| Average (mean) | $18.01 | $37,460 | $18.64 |
From the bottom tenth ($13.65) to the top tenth ($23.56), the top of the scale pays about 1.7 times the bottom in Idaho, close to the 1.8 times spread for janitors nationwide.
Both ends trail the national figures. The bottom tenth earn $0.12 an hour less than the bottom tenth nationally, and the top tenth $0.61 less than the national top tenth.
The average, $18.01, is close to the median, so pay sits fairly evenly around the middle.
How Idaho compares with other states

Against its neighboring states, Idaho is in the middle: Montana, Nevada, Oregon and Washington pay more, and Utah and Wyoming pay less.
How many janitors work in Idaho
About 10,800 janitors work on payrolls in Idaho, 0.5% of the 2,209,760 nationwide, the 40th largest count among the states.
That is 12.6 of every 1,000 jobs in Idaho, close to the trade's share of jobs nationally.
What a commercial cleaning company in Idaho should charge
Say you run a commercial cleaning company in Idaho and pay the state median of $17.36 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 | $17.36 × 2,080 × 1.0765 | $38,871 |
| Break-even rate | ($38,871 + $90,000) ÷ 1,500 | $85.91 |
| Rate with 15% profit | $85.91 ÷ 0.85 | $101.08 |
That is $101.08 per billable hour, 5.8 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, $19.00 in Idaho, to hire and keep experienced people raises the rate to $103.96.
A cheaper crew saves less than it seems: at the 25th percentile wage of $15.50, the rate only drops to $97.81.
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.
