Janitorial Supply Usage Calculator
Estimate monthly usage and cost of common janitorial supplies based on your facility size, number of occupants, and cleaning schedule.
Formulas Used
- Trash Bags/month = ⌈sq ft ÷ 1,000⌉ × facility multiplier × cleaning days
- Paper Towel Rolls/month = occupants × 0.05 rolls/person/day × facility multiplier × cleaning days
- Toilet Paper Rolls/month = restrooms × 2 rolls/restroom/day × facility multiplier × cleaning days
- All-Purpose Cleaner (oz)/month = (sq ft ÷ 500) × 2 oz × facility multiplier × cleaning days → divide by 32 for bottles
- Disinfectant (oz)/month = restrooms × 8 oz/restroom/day × facility multiplier × cleaning days → divide by 32 for bottles
- Floor Cleaner (oz)/month = (sq ft ÷ 1,000) × 4 oz × facility multiplier × cleaning days → divide by 128 for gallons
- Mop Head Replacements/month = ⌈(sq ft ÷ 5,000) × facility multiplier⌉ × cleaning days ÷ 200 uses per head
- Microfiber Cloths/month = ⌈sq ft ÷ 2,000⌉ × facility multiplier × cleaning days ÷ 50 washes per cloth

Assumptions & References
- Baseline consumption rates derived from ISSA (Worldwide Cleaning Industry Association) cleaning time standards and commercial supply usage benchmarks.
- Paper towel usage: ~0.05 rolls per person per day based on ISSA restroom supply guidelines (approx. 200 sheets/roll, ~10 uses/person/day).
- Toilet paper: 2 rolls per restroom per cleaning day assumes moderate-to-heavy traffic; adjust for low-traffic facilities.
- All-purpose cleaner dilution: 2 oz concentrate per 500 sq ft per cleaning session (standard RTU or diluted spray application).
- Disinfectant: 8 oz per restroom per cleaning day per EPA-registered disinfectant label directions for restroom surfaces.
- Floor cleaner: 4 oz per 1,000 sq ft per cleaning day based on standard mop-bucket dilution ratios (1:32 concentrate).
- Mop head lifespan: ~200 uses per head (ISSA recommendation for microfiber flat mops).
- Microfiber cloth lifespan: ~50 laundry cycles per cloth (manufacturer standard).
- Unit costs are approximate 2024 U.S. commercial/janitorial distributor prices and will vary by region and supplier.
- Medical facilities use a 2.0× multiplier to reflect enhanced disinfection protocols per CDC environmental cleaning guidelines.
- Results are estimates only. Actual usage depends on occupant behavior, soil levels, and specific cleaning protocols.
