How to use this janitorial bid calculator

Determine cleanable square footage

Do not enter the gross square footage of the building. Deduct areas that do not require daily or weekly service, such as raw storage warehouses, mechanical rooms, or unoccupied suites. Enter only the active "cleanable" space.

Select the facility profile

Different environments have drastically different production rates. Industrial floors can be auto-scrubbed quickly (high sqft/hr), while medical facilities require slow, deliberate dwell times with EPA-registered disinfectants (low sqft/hr).

Adjust for frequency multipliers

Cleaning an office once a week takes longer per visit than cleaning it five times a week, because dirt and trash accumulate. The tool automatically applies a time-reduction multiplier for high-frequency service schedules.

Review labor and margin breakdowns

Input your local hourly wage. The calculator determines total monthly labor cost, then applies a standard 40% margin to cover cleaning supplies, equipment depreciation, insurance, and company profit to output your final monthly bid.

Frequently asked questions

Why are medical cleaning rates so much higher?

Medical and healthcare facilities require strict adherence to OSHA bloodborne pathogen standards and terminal cleaning protocols. Staff must use hospital-grade, EPA-registered disinfectants that require specific "dwell times" (leaving the surface wet for 3-10 minutes) before wiping. This drastically reduces the square footage a cleaner can cover per hour, increasing labor costs.

Does cleaning every day cost more than cleaning once a week?

Yes, the total monthly cost is higher for daily cleaning, but the cost per visit drops. If a facility is only cleaned once a week, dirt, floor scuffs, and overflowing trash compound, requiring deep cleaning every visit. If cleaned 5 times a week, daily maintenance is much faster, allowing cleaners to cover the same square footage in 15% to 20% less time per visit.

What is a normal profit margin for a cleaning company?

In the US commercial cleaning industry, gross margins typically range from 30% to 45%. After deducting direct labor, this margin covers payroll taxes, workers' compensation insurance, chemical supplies, vacuum depreciation, management overhead, and the company's net profit. This calculator utilizes a standard 40% combined margin structure.

What is an ISSA Production Rate?

ISSA (The Worldwide Cleaning Industry Association) publishes standard time metrics for specific cleaning tasks (e.g., how long it takes to vacuum 1,000 sq ft or disinfect a restroom). Professional bidding relies on these aggregate production rates rather than guessing, ensuring bids are mathematically profitable.

About this calculator

This commercial cleaning calculator transitions pricing from guesswork to data-driven forecasting. It utilizes aggregate production rates to determine exact labor needs before applying financial margins.

The pricing engine is driven by these core mathematical rules:

Production Rate = Office (3,500 sq ft/hr) | Medical (2,500 sq ft/hr) | Industrial (5,000 sq ft/hr)

Base Hours per Visit = Total Sq Ft ÷ Production Rate

Frequency Multiplier = 1-2x (1.0) | 3-4x (0.90) | 5-7x (0.85)

Total Monthly Hours = (Base Hours × Frequency Multiplier) × (Days per Week × 4.33 Weeks)

Total Monthly Cost = (Total Monthly Hours × Hourly Labor Rate) ÷ (1 - 0.40 Overhead Margin)

A note on custom bidding: This tool assumes average workstation density and standard hard floor-to-carpet ratios. Facilities with high-density cubicles, excessive glass partitions, or requirements for specialized floor stripping/waxing will require custom labor add-ons beyond standard production rates.
