Ever wonder how many calories you burn just tidying up, vacuuming, or doing laundry? This calculator estimates the calories you burn during 15 minutes of common household chores, based on your weight and the intensity of the activity. It uses the Metabolic Equivalent of Task (MET) values from the Compendium of Physical Activities, a widely used research standard.
Whether you're tracking your daily movement, planning a gentle fitness routine, or just curious about the effort behind a clean house, this tool gives you a quick, science-backed estimate. Simply enter your weight, choose an activity, and hit calculate to see your estimated calorie burn for a 15-minute session.
Perfect for anyone interested in low-impact exercise, gentle movement, or making everyday chores count toward their activity goals.

How to Use This Tool
Enter your body weight in kilograms or pounds, select the household activity that matches what you're doing, and optionally check the "vigorous effort" box if you're working harder than usual. Then click Calculate to see your estimated calorie burn for a 15-minute session. The result is based on the standard MET formula used in exercise science.
For the most accurate estimate, choose the activity that best matches your actual movements. If you're doing a combination of chores, you can calculate each segment separately and add the results. The calculator automatically converts pounds to kilograms, so you don't need to worry about unit conversions.
Formula Explained
The calculator uses the widely accepted MET (Metabolic Equivalent of Task) method:
Calories per minute = MET × 3.5 × weight (kg) ÷ 200
For a 15-minute session, we multiply by 15. If you select vigorous effort, we apply a 20% increase (multiply by 1.2).
MET values represent the energy cost of an activity relative to resting. For example, light cleaning has a MET of 3.0, meaning you burn three times more energy than at rest. These values come from the Compendium of Physical Activities, a research resource maintained by exercise scientists.
The 3.5 in the formula represents the average oxygen consumption at rest (3.5 ml/kg/min), and 200 is a conversion factor that translates oxygen consumption into calories. This formula is standard in exercise physiology and is used by many fitness trackers and health organizations.
Worked Examples
Example 1: A 70 kg person vacuuming (MET 3.5) for 15 minutes:
Calories = 3.5 × 3.5 × 70 ÷ 200 × 15 = 64.3 kcal
Example 2: A 150 lb person (68 kg) doing light cleaning (MET 3.0) with vigorous effort:
Calories = 3.0 × 3.5 × 68 ÷ 200 × 15 × 1.2 = 64.3 kcal
Example 3: A 60 kg person moving furniture (MET 4.5) for 15 minutes:
Calories = 4.5 × 3.5 × 60 ÷ 200 × 15 = 70.9 kcal
These examples show how weight and activity intensity affect the final number. Heavier individuals burn more calories for the same activity because their bodies require more energy to move.
Tips & Best Practices
- Be consistent with your weight unit – the calculator converts automatically, but double-check your entry.
- If you're doing a mix of chores, estimate the average intensity or calculate each segment separately.
- Remember that calorie burn is an estimate; individual metabolism varies.
- Use this tool to track your daily non-exercise activity thermogenesis (NEAT) – it adds up!
- For weight loss, combine household chores with a balanced diet and regular exercise. A 15-minute session might burn 50–80 calories, which can contribute to a weekly deficit of 350–560 calories if done daily.
Factors Affecting Accuracy
Your actual calorie burn depends on your age, gender, muscle mass, and fitness level. The MET values assume an average adult. If you're very fit, you might burn slightly more; if you're less conditioned, slightly less. Also, the intensity of your movements matters – brisk vacuuming burns more than slow dusting.
Environmental factors like temperature and humidity can also influence energy expenditure. Working in a hot room may increase your heart rate and calorie burn slightly, while air conditioning might reduce it. However, these effects are usually small compared to the main variables of weight and intensity.
Frequently Asked Questions
Can I lose weight just by doing housework?
Yes, consistent daily chores can contribute to a calorie deficit, especially when combined with a healthy diet. A 15-minute session might burn 50–80 calories, which adds up over a week. For example, 30 minutes of vacuuming daily could burn an extra 1,200–1,500 calories per month, potentially leading to about 0.15–0.2 kg of fat loss per month, assuming no other changes.
How accurate is this calculator?
It's a good estimate based on scientific MET values, but individual results vary. For precise tracking, consider a fitness tracker that measures heart rate. The MET method has an accuracy of roughly ±20% for most people, which is acceptable for general fitness purposes.
What if I do more than 15 minutes?
Simply multiply the result by the number of 15-minute blocks. For example, 30 minutes would be double the estimate. If you do 45 minutes, multiply by 3. This linear scaling works because the formula is proportional to time.
Are there any activities not listed?
Yes, the list covers common chores, but you can approximate others. For example, gardening has a MET of about 4.0, similar to mopping. If your activity isn't listed, choose the closest match or use the average MET of 3.5 for general housework.
