House Cleaning Time Estimator
Estimate how long it will take to clean your home based on square footage, number of rooms, bathrooms, and cleaning intensity.
Formula
Step 1 – Base time (single cleaner):
T = ((sqft × 0.02 + bedrooms × 15 + bathrooms × 25) × CleanMultiplier × ClutterMultiplier) + (pets × 15)
Step 2 – Adjust for multiple cleaners:
Efficiency = 1 + (cleaners − 1) × 0.85
Adjusted Time = T ÷ Efficiency
Clean Type Multipliers: Light = 0.6 × | Standard = 1.0 × | Deep = 1.8 × | Move-In/Out = 2.2 ×
Clutter Multipliers: Low = 0.85 × | Medium = 1.0 × | High = 1.3 ×
Estimated range: ±15% of the calculated time.
Assumptions & References
- Base rate of 0.02 minutes per sq ft reflects average cleaning speed for general surface wiping, vacuuming, and mopping (ARCSI industry guidelines).
- Bedroom time of 15 min/room covers dusting, vacuuming, and surface wiping for a standard-sized bedroom (~150 sq ft).
- Bathroom time of 25 min/room covers toilet, sink, shower/tub, mirror, and floor for a standard bathroom.
- Deep cleaning (1.8×) includes baseboards, inside appliances, cabinet fronts, and detailed scrubbing per ISSA cleaning standards.
- Move-in/move-out cleaning (2.2×) includes inside cabinets, oven, refrigerator, and all surfaces per real estate turnover standards.
- Each additional cleaner is assumed to operate at 85% of a solo cleaner's efficiency due to coordination overhead and shared equipment.
- Pet add-on accounts for extra hair removal, dander, and odor treatment (15 min per pet level).
- Estimates are for residential cleaning; commercial or specialty cleaning may vary significantly.
