Office size tiers
| Office size | Calculator rule |
|---|---|
| Under 1,000 sq ft | $120–$400/month minimum monthly job floor |
| 1,000–2,999 sq ft | $0.07–$0.15/sq ft/month at 3x weekly baseline |
| 3,000+ sq ft | $0.10–$0.20/sq ft/month at 3x weekly baseline |
Cost calculator
Commercial cleaning cost calculator
Estimate recurring office cleaning cost from square footage and cleaning frequency. This calculator uses monthly square-foot rates with frequency factors, a small-job floor, and quote-only handling for unsourced facility types.
Pricing source:
Office is the only facility type with a defensible Phase 1 monthly square-foot model. The calculator rules are shown on this page: a sub-1,000 sq ft minimum monthly floor, a 1,000–2,999 sq ft monthly office tier, a 3,000+ sq ft monthly office tier, and non-linear frequency factors. Hourly rates remain separate context and are not blended into the square-foot math.
How this calculator works
This tool estimates recurring office cleaning only. It uses the calculator’s internal monthly office tiers, then applies a non-linear frequency factor. It does not multiply the monthly square-foot estimate by the number of monthly cleanings again.
Cleaning frequency factors
| Frequency | Factor | Reason |
|---|---|---|
| 1x weekly | 0.45 | Lower frequency still carries setup and minimum-cost overhead. |
| 2x weekly | 0.7 | More frequent service spreads fixed labor and setup cost across more cleanings. |
| 3x weekly | 1.0 | Baseline used by the calculator. |
| Daily / 5x weekly | 2.0 | Higher frequency is not priced as a straight-line multiple. |
Frequency source:
Buildingstars notes that higher cleaning frequency often lowers the price per cleaning, so 4x weekly is not simply twice 2x weekly; very high frequency can break that pattern because staffing becomes harder, and daytime cleaning can cost more than overnight cleaning.

What the estimate does not include
These items can change a provider quote, but they are not included in the office calculator’s monthly square-foot estimate.
| Excluded item | Verified published range | Why it is separate |
|---|---|---|
| Carpet cleaning | $0.08–$0.40/sq ft | Different equipment and labor than routine vacuuming. |
| Floor stripping and waxing | $0.30–$0.80/sq ft | Specialized floor work should be scoped separately from janitorial service. |
| Window cleaning | $2–$7 per pane | Pane count can matter more than building square footage. |
| Restroom sanitizing add-on | $25–$75+ | Restroom load can change labor time disproportionately. |

Worked calculator examples
Small office floor
A 900 sq ft office is below the reliable square-foot band, so the calculator applies the $120–$400/month minimum monthly job floor instead of pretending the square-foot math is precise.
Office at baseline frequency
A 5,000 sq ft office cleaned three times weekly uses the 3,000+ sq ft tier of $0.10–$0.20 per sq ft per month and the 1.0 baseline frequency factor, resulting in $500–$1,000/month.
Same office cleaned daily
The same 5,000 sq ft office cleaned five times weekly uses the 2.0 daily factor, resulting in $1,000–$2,000/month before any provider-specific add-ons or exclusions.

Calculator FAQ
Is this estimate per month or per cleaning?
The estimate is monthly. The calculator uses monthly office square-foot tiers and frequency factors.
Why are specialized facility types quote-only?
Medical, restaurant, warehouse, and post-construction scopes can change labor, supplies, timing, access, and risk more than square footage alone.
What happens below 1,000 square feet?
The calculator applies the $120–$400/month minimum monthly job floor because small-office square-foot math is not reliable.
Does daily cleaning cost a straight-line multiple?
No. The calculator uses non-linear frequency factors, and the Buildingstars source notes that more frequent cleaning often changes the price per cleaning.
What should I confirm with providers?
Confirm frequency, room scope, floor work, restrooms, supplies, access timing, exclusions, and whether add-ons are included.
Why units stay separate
Commercial cleaning prices appear as hourly rates, square-foot prices, flat project prices, and monthly totals. A credible calculator should not blend those units unless the conversion assumptions are explicit.
