House Cleaning Schedule Calculator Formula

Understand the math behind the house cleaning schedule calculator. Each variable explained with a worked example.

Formulas Used

Weekly Cleaning Hours

weekly_hours = base_hours

Monthly Professional Cost (2x/mo)

monthly_pro_cost = base_hours * cleaning_rate * 2

Annual Professional Cost (2x/mo)

annual_pro_cost = base_hours * cleaning_rate * 24

How It Works

Estimating Cleaning Time and Cost

Cleaning time depends on home size, number of occupants, and how thorough the cleaning needs to be.

Estimation

Weekly Hours = (Sq Ft / 1000) x 1.5 + Occupants x 0.3

A 2,000 sq ft home takes approximately 3-4 hours per cleaning session. More occupants and pets generate more mess, increasing time proportionally.

Worked Example

A 2,000 sq ft home with 3 occupants, professional cleaning at $35/hr.

sqft = 2000occupants = 3cleaning_rate = 35
  1. 01Base hours = (2000/1000) x 1.5 + 3 x 0.3 = 3.0 + 0.9 = 3.9 hours
  2. 02Monthly cost (2x) = 3.9 x $35 x 2 = $273
  3. 03Annual cost = 3.9 x $35 x 24 = $3,276
