House Cleaning Calorie Formula: MET Values for Every Cleaning Activity
The house cleaning calorie formula uses MET values from the Ainsworth Compendium. Light tidying = MET 2.5, general cleaning = MET 3.0, vacuuming = MET 3.5, heavy scrubbing = MET 4.5. Full tables and examples inside.
The house cleaning calorie formula is straightforward: Calories = MET × Weight (kg) × Time (hours). The MET (Metabolic Equivalent of Task) value changes based on what type of cleaning you're doing — from 2.5 for light dusting up to 4.5 for vigorous bathroom scrubbing.

The MET Formula for House Cleaning
The formula used by exercise scientists to calculate calories burned during any physical activity is:
Calories = MET × Weight (kg) × Time (hours)
Where:
- MET = Metabolic Equivalent of Task (the intensity of the activity)
- Weight = your body weight in kilograms
- Time = duration in hours (e.g. 30 minutes = 0.5 hours)
This formula comes from the Ainsworth Compendium of Physical Activities, which is the standard reference used by researchers, fitness professionals, and health organizations worldwide to quantify energy expenditure.
MET Values for House Cleaning Activities
Not all cleaning is equal. The MET values reflect the true physiological effort of each cleaning task:
| Cleaning Activity | MET Value | Intensity Level | Examples |
|---|---|---|---|
| Light Tidying | 2.5 | Light | Dusting, folding laundry, organizing |
| General Housework | 3.0 | Light–Moderate | Dishwashing, wiping surfaces, general tidying |
| Vacuuming & Mopping | 3.5 | Moderate | Vacuuming carpets, mopping hard floors |
| Heavy Scrubbing | 4.5 | Moderate–Vigorous | Scrubbing bathrooms, oven cleaning, moving furniture |
A MET of 1.0 represents sitting at rest. So MET 3.0 (general cleaning) means your body is burning three times as many calories as it would sitting still. At MET 4.5 (heavy scrubbing), you're burning 4.5 times your resting rate — that's firmly in moderate exercise territory.

Example Calculations
Example 1: 70 kg person, 45 minutes of general cleaning (MET 3.0)
Calories = 3.0 × 70 × (45 ÷ 60)
= 3.0 × 70 × 0.75
= 158 kcal
Example 2: 85 kg person, 30 minutes of vacuuming (MET 3.5)
Calories = 3.5 × 85 × (30 ÷ 60)
= 3.5 × 85 × 0.5
= 149 kcal
Example 3: 60 kg person, 20 minutes of bathroom scrubbing (MET 4.5)
Calories = 4.5 × 60 × (20 ÷ 60)
= 4.5 × 60 × 0.333
= 90 kcal
Why the MET Formula Is Used for Cleaning Calories
The MET-based approach is the gold standard for estimating non-exercise physical activity energy expenditure for several reasons:
Population-validated: MET values from the Ainsworth Compendium are derived from multiple research studies measuring actual oxygen consumption during cleaning tasks. They represent the best available average across different body types and cleaning styles.
Weight-adjusted accuracy: Unlike generic "calories per hour" charts that ignore body weight, the formula scales directly with mass. A 100 kg person doing the same cleaning task as a 60 kg person burns 67% more calories — the formula captures this automatically.
Easy to apply: You only need your weight, duration, and cleaning type to get a reasonable estimate. No heart rate monitor or specialized equipment required.
Limitations: The formula gives a population average. Your actual calorie burn will vary by ±20–30% depending on individual factors like fitness level, cleaning technique, home layout (stairs vs single floor), and how vigorously you move between tasks.
How Much Cleaning Does It Take to Burn 200 Calories?
For a 70 kg person:
| Cleaning Activity | Time to Burn 200 Calories |
|---|---|
| Light Tidying (MET 2.5) | ~69 minutes |
| General Housework (MET 3.0) | ~57 minutes |
| Vacuuming & Mopping (MET 3.5) | ~49 minutes |
| Heavy Scrubbing (MET 4.5) | ~38 minutes |
Heavy scrubbing is the most calorie-efficient cleaning activity — you can burn 200 calories in under 40 minutes of vigorous effort.
Does House Cleaning Count as Exercise?
Activities at MET ≥ 3.0 qualify as moderate-intensity physical activity by the World Health Organization's guidelines. This means general housework, vacuuming, mopping, and scrubbing all count toward the recommended 150–300 minutes per week of moderate activity.
Light tidying (MET 2.5) falls just below this threshold and is classified as light activity — still beneficial for your health and daily calorie burn, but not quite exercise intensity.
