Executive summary
The benchmark is a range, not a shortcut
Commercial cleaning prices become useful only when the assumptions underneath them are visible. Two 20,000-square-foot buildings can require radically different labor because of restroom density, flooring, occupancy, security, service level, equipment, and frequency.
That is why this report does not publish a single “correct” price per square foot. It publishes a reproducible model. Start with a facility profile, inspect the implied labor hours, then replace each planning assumption with facts from your walkthrough and operating history.
The U.S. Bureau of Labor Statistics reports a $17.71 national median hourly wage for janitors and building cleaners in May 2025 . The benchmark uses that as its default wage anchor—not as a recommended wage for every market.

Modeled results
How facility type changes the estimate
The table holds area, frequency, wage, burden, supplies, overhead, and margin constant. Only the planning production rate changes. Slower workloading creates more labor hours and a higher monthly price.
| Facility profile | Modeled sq. ft./hr | Area | Visits/week | Monthly price | Monthly $/sq. ft. |
|---|---|---|---|---|---|
| General office | 3,500 | 20,000 | 5 | $4,250 | 21.2¢ |
| Medical office | 2,200 | 20,000 | 5 | $6,760 | 33.8¢ |
| School / education | 2,800 | 20,000 | 5 | $5,310 | 26.6¢ |
| Warehouse | 6,000 | 20,000 | 5 | $2,480 | 12.4¢ |
Scenario assumptions: 20,000 cleanable sq. ft.; five visits/week; $17.71 wage; 25% labor burden; supplies equal to 8% of burdened labor; 15% overhead; 20% target operating margin. Rounded to the nearest $10 and tenth of a cent.
Frequency adjustment
Frequency multiplies labor—but scope still matters
This office scenario holds hours per visit constant to isolate frequency. In practice, frequent service may reduce soil buildup while every visit still adds setup, access, travel, and closing time. Estimate each offered frequency separately.
| Frequency | Monthly visits | Modeled monthly price | Monthly $/sq. ft. |
|---|---|---|---|
| 1 visit/week | 4.3 | $850 | 4.3¢ |
| 2 visits/week | 8.7 | $1,700 | 8.5¢ |
| 3 visits/week | 13.0 | $2,550 | 12.8¢ |
| 5 visits/week | 21.7 | $4,250 | 21.2¢ |
Production methodology
Measure the building, not the rumor
ISSA explains that square footage alone is insufficient: the standard of clean, facility type, tools, training, scope, and whether work is daily, interim, or restorative all affect workloading.
ISSA’s recommended time-study method is practical: choose a task, measure the area, record multiple observations, average the times, adjust for building variables, and refine the rate as actual results accumulate.
Production-rate checklist
- ✓Use cleanable—not gross—square footage.
- ✓Separate recurring, periodic, and restorative tasks.
- ✓Count restrooms, fixtures, waste points, and high-touch surfaces.
- ✓Record travel, access, setup, security, and closing time.
- ✓Identify the equipment and crew configuration used.
- ✓Compare budgeted hours with actual hours after startup.
Margin sensitivity
Margin and markup are not interchangeable
For a target margin, divide cost by one minus the margin. A $4,000 operating cost at a 20% target margin requires a $5,000 selling price. Adding a 20% markup produces only $4,800 and a 16.7% margin.
15% margin
$4,706
$706 gross profit on $4,000 cost
20% margin
$5,000
$1,000 gross profit on $4,000 cost
25% margin
$5,333
$1,333 gross profit on $4,000 cost
Methodology and limitations
Exactly what this model assumes
- 1. Labor time: cleanable square footage ÷ modeled production rate × weekly visits × 4.33 weeks.
- 2. Burdened labor: monthly hours × wage × (1 + labor burden). The 25% default is a scenario input, not an industry average. BLS reports that benefits represented 30.1% of total private-industry compensation in March 2026, but your taxes, insurance, leave, and benefits can differ materially.
- 3. Supplies: modeled as 8% of burdened labor for comparability. Replace it with chemicals, liners, equipment, and consumables actually included in the contract.
- 4. Overhead: 15% is applied to labor plus modeled supplies. It represents a planning allocation for supervision, administration, insurance, software, and other operating costs.
- 5. Price: operating cost ÷ (1 − target margin). The result is a planning benchmark before job-specific taxes, travel, unusual conditions, and local requirements.
