Janitor pay in South Dakota, bottom to top

| Pay level | Hourly | Yearly | National hourly |
|---|---|---|---|

Pay is bunched up in South Dakota. The top tenth earn $21.51 an hour or more, about 1.5 times the $13.93 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 ($13.93 against $13.77) but the ceiling is lower ($21.51 against $24.17), which squeezes pay toward the middle.
The average, $17.48, is close to the median, so pay sits fairly evenly around the middle.

What a commercial cleaning company in South Dakota should charge
Say you run a commercial cleaning company in South Dakota and pay the state median of $17.06 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 | $17.06 × 2,080 × 1.0765 | $38,199 |
| Break-even rate | ($38,199 + $90,000) ÷ 1,500 | $85.47 |
| Rate with 15% profit | $85.47 ÷ 0.85 | $100.55 |
That is $100.55 per billable hour, 5.9 times the wage, and $1.14 less than the $101.69 the same math gives at the national median wage.
Paying the 75th percentile instead, $18.81 in South Dakota, to hire and keep experienced people raises the rate to $103.62.
A cheaper crew saves less than it seems: at the 25th percentile wage of $15.03, the rate only drops to $96.98.
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.
