ISSA 612 method
Office Cleaning Cost Calculator
Price office janitorial work from carpet or hard-floor scope, trash service, restroom fixtures, and cleaning frequency. The calculator starts with an office preset and keeps the math visible.
Preset checked before publishing
The office preset uses 10,000 sqft, daily service, carpet, trash, and restrooms so the starting estimate lines up with common monthly office-cleaning shorthand. Example table row: $1,727/mo, $0.173/sqft/month.

Inside common monthly shorthand range
Common office cleaning references often show $0.10- $0.18/sqft but do not always label monthly vs. per-visit math. CleanScope shows both; it does not inflate the engine output.
How this estimate is calculated+
ISSA 612 task times
Hours come from seeded production-rate rows, not a hidden multiplier.
Transparent assumptions
Default overhead is 10%; profit is 15%; labor burden uses the selected state profile.
Same engine path
The public tool calls the same pure calculation engine used inside CleanScope proposals.
Calculation method
How the estimate is calculated
Office bids usually swing on cleaning frequency, restroom density, and how much carpet or open workspace is in the route. CleanScope converts those tasks into labor hours before adding burden, overhead, and profit.
Task hours
Square footage is divided by the matching ISSA production rate. Restrooms use fixture counts instead of square footage.
Monthly workload
Each task is multiplied by the selected cleaning frequency, such as daily, weekly, or monthly.
Burdened labor
Base wage is adjusted for FICA, SUTA, and workers comp using the selected state labor profile.
Contract price
The engine adds 10% overhead and 15% profit, then returns monthly and annual contract value.

FAQ
Office cleaning calculator questions
How much should I charge for office cleaning?+
Start with square footage, floor type, restroom fixtures, trash service, and visit frequency. The office calculator converts that scope into labor hours, then adds labor burden, overhead, and profit.
Why does office cleaning price per square foot change by size?+
Fixed restroom time and trash routes matter more in smaller offices. Larger offices spread those tasks over more square feet, so monthly price per square foot can move lower.
Can I use this for nightly office janitorial bids?+
Yes. Use the daily frequency preset, confirm restroom counts and floor mix, then treat the output as a starting estimate before a final walkthrough.
