Janitorial Staffing Calculator
Calculate the number of janitorial staff needed, hours per shift, and monthly labor budget based on facility size, type, and cleaning frequency.
About this calculator
Janitorial staffing starts from an industry-standard cleaning rate: how many square feet one person can reasonably clean in an hour, which varies a lot by facility type. This calculator uses 3,500 sq ft/hr as a baseline for offices, dropping to 2,000 for medical spaces (which need more careful disinfection and detail work) and rising to 5,000 for industrial spaces (typically more open floor plans with less detail cleaning). Facility Size and Facility Type together set Hours per Visit and, through the 8-hour shift assumption, Staff Needed — a facility twice the size needs roughly twice the hours, and switching facility types can swing the required hours by more than 2x even at the same square footage, since the cleaning rate itself ranges from 2,000 to 5,000 sq ft/hr across the five categories.
Cleaning Frequency then multiplies that per-visit labor by how many times a month the space gets cleaned, so Monthly Labor Cost and Annual Budget scale with both facility size and visit frequency together. Labor costs use a single flat burdened rate of $22/hour (wages plus estimated taxes and benefits) rather than a regional or role-specific rate, so treat the dollar figures as a rough starting estimate to recalibrate with your actual local labor costs, not a quote.

Frequently Asked Questions
Why does changing Facility Type matter so much?
Facility Type sets the cleaning rate used to estimate Hours per Visit, and that rate varies widely — from 2,000 sq ft/hr for medical spaces up to 5,000 sq ft/hr for industrial spaces. At the same square footage, switching between the lowest and highest rate category can more than double the estimated hours needed, which is a bigger swing than a typical change in facility size alone.
How does Facility Size affect my labor cost?
Facility Size feeds directly into Hours per Visit (larger facilities take proportionally longer to clean at the same rate) and from there into Monthly Labor Cost, so a larger space costs more to clean in roughly direct proportion to its added square footage, holding facility type and frequency constant.
Why does the medical facility rate assume slower cleaning?
Medical spaces typically require more careful disinfection protocols, detail cleaning around equipment, and infection-control procedures than an open office layout, which slows the effective cleaning rate. This calculator models that as a lower square-feet-per-hour figure (2,000 vs. 3,500 for a standard office) rather than a separate protocol adjustment.
Is the $22/hour labor rate accurate for my area?
It's a single flat national planning estimate representing burdened labor cost — wages plus estimated payroll taxes and benefits — not a rate tailored to your region, union contract, or staffing agency markup. Local janitorial labor costs can vary significantly, so use the dollar outputs as a starting baseline to adjust against your actual market rate.
How does Cleaning Frequency change the monthly budget?
Cleaning Frequency sets how many visits happen per month — roughly 22 for daily service, 13 for three times a week, and about 4.3 for weekly — and Monthly Labor Cost scales with that visit count times the per-visit labor cost. Moving from weekly to daily service multiplies the monthly labor cost by roughly five, purely from the ~5x jump in visit count (22 vs. 4.33) — the hours-per-visit figure itself is fixed by Facility Sq Ft and Facility Type and doesn't change with frequency.
