- Question
- How many calories do household chores burn?
- Answer
- kcal = MET × weight_kg × hours. Using published MET values from the Compendium of Physical Activities: vacuuming ≈ 3.5 MET, washing dishes ≈ 1.8, mopping ≈ 3.5, raking leaves ≈ 4.0, mowing a lawn ≈ 5.5, gardening ≈ 3.5. A 70 kg person vacuuming for 30 minutes burns about 3.5 × 70 × 0.5 = 122 kcal. The formula is a solid ballpark — real burn varies ±20% by intensity and body composition.

- Formula
kcal = MET × weight_kg × hours- Caveats
- MET values assume continuous activity. Breaks lower the real burn.
- Compendium values are averages for 'healthy adults' — individual metabolic rates vary.
- Activity trackers often overestimate non-exercise chore burn because they can't distinguish intensity.
What This Calculator Does
This calculator estimates calories burned during household chores by applying the Metabolic Equivalent of Task (MET) value for each activity to your body weight and time spent. One MET is roughly the energy cost of sitting quietly — about 1 kcal per kg of body weight per hour. Vacuuming at 3.5 MET means you burn about 3.5× that baseline while you do it. The calculator uses published MET values from the Compendium of Physical Activities (Ainsworth et al.) and the simple formula Calories = MET × kg × hours. It's a useful ballpark but not a precision tool — actual burn varies with intensity, body composition, and how much rest is folded into 'active' time.
When To Use This Calculator
Adding non-exercise activity to a calorie diary
You vacuumed for 30 minutes and mopped for 20. At 165 lb (75 kg): vacuuming (3.5 MET) × 75 × 0.5 ≈ 131 cal; mopping (3.5 MET) × 75 × 0.33 ≈ 87 cal. About 218 calories from household chores — worth logging if you track intake.
Deciding whether a weekend of yard work counts as a workout
Two hours of mowing (5.5 MET) at 180 lb (82 kg): 5.5 × 82 × 2 ≈ 900 calories. That's comparable to a 90-minute jog — enough that skipping your usual run that day is reasonable.
Comparing the energy cost of chores to structured exercise
Shoveling snow (6.0 MET) for a 155-lb (70 kg) person burns about 420 calories/hour — slightly more than a moderate spin class. Useful context when 'I did chores all day' gets written off as sedentary.
Estimating NEAT contribution to daily TDEE
If you clean 45 min/day at 3.0 MET and weigh 150 lb (68 kg), you add ~150 cal/day or ~1,050 cal/week. That's a meaningful chunk of the non-exercise activity thermogenesis (NEAT) that separates desk-bound days from active ones.
How It Works
MET (Metabolic Equivalent of Task) expresses the energy cost of an activity relative to sitting at rest. 1 MET ≈ 3.5 mL O₂/kg/min ≈ 1 kcal/kg/hour. To estimate calories burned, multiply the activity's MET value by your body mass in kilograms and the time spent in hours. MET values are empirically derived averages — the Compendium of Physical Activities lists values for hundreds of activities based on indirect calorimetry studies. The calculator converts weight from lb to kg automatically (1 lb = 0.4536 kg) and time from minutes to hours before applying the formula.
Formula
Calories = MET × weight(kg) × time(hours)Real-World Example
Scenario
Diana weighs 140 lb (63.5 kg) and spends Saturday morning on chores: 45 minutes vacuuming, 30 minutes scrubbing the bathroom, and 20 minutes folding laundry.
Calculation
Vacuuming (3.5 MET): 3.5 × 63.5 × 0.75 ≈ 167 cal Scrubbing (4.0 MET): 4.0 × 63.5 × 0.50 ≈ 127 cal Laundry (2.0 MET): 2.0 × 63.5 × 0.33 ≈ 42 cal Total: 167 + 127 + 42 ≈ 336 calories
Result
About 336 calories across a 95-minute session — roughly equivalent to a 35-minute moderate run. It's a useful reminder that active chores contribute meaningfully to daily energy expenditure, though individual numbers will vary ±15–20% based on effort level and body composition.
Common Mistakes to Avoid
Mistake: Double-counting chores if your TDEE already includes activity
Solution: If you've already set your activity multiplier to 'moderate' or higher in a TDEE calculator, the chore burn is partially baked in. Don't add the full chore calories on top of maintenance and expect to lose weight — estimate your base TDEE at 'sedentary' and add chores separately, or just trust the higher activity multiplier.
Mistake: Using MET values for 'full-intensity' activity when you take frequent breaks
Solution: MET values assume continuous effort. If your 'hour of gardening' includes 20 minutes of standing around or scrolling your phone, the effective MET drops. Track only the minutes you were actively moving, or discount the time by 20–30%.
Mistake: Treating chore calories as a license to overeat
Solution: Calorie-burn estimates are inherently noisy (±15–25% is typical), and research shows people routinely overestimate activity and underestimate food intake. Use the numbers as directional — consistent behavior over weeks, not any single day's math, drives weight outcomes.
Mistake: Assuming heavier equals always more calories
Solution: Heavier bodies do burn more calories at a given MET, but fitter people often complete a chore faster, so total burn can be similar. And for very heavy loads (moving furniture), actual energy cost can exceed the listed MET if the activity pushes into muscular-strain territory.

When This Isn't the Right Tool
High-precision calorie tracking
Use instead: MET-based estimates carry 15–25% error. If you need tighter numbers (for clinical studies, competitive athletes cutting weight), use indirect calorimetry, a heart-rate-based estimate with a chest strap, or a metabolic cart.
Chores that mix activities of different intensities
Use instead: 'Cleaning the house' often bundles vacuuming, scrubbing, standing, and walking. Break the session into per-activity segments or accept that a single MET value will smooth out a lot of variance.
Children, pregnant individuals, or people with mobility limitations
Use instead: The Compendium of Physical Activities is validated primarily in healthy adults. Pediatric and youth MET values are published separately. Adapted MET values exist for some populations — consult a clinical exercise physiologist for precise estimates.
Very short activities (<5 minutes)
Use instead: MET assumes a steady-state energy cost. A 3-minute burst of stair-climbing spends energy mostly on anaerobic work that isn't captured well by a 15-minute average. For short bouts, the estimate is directional at best.
How to Verify This Calculation
Cross-check against the Compendium of Physical Activities (compendiumofphysicalactivities.org) or a fitness tracker's built-in estimate. A 30-minute moderate chore session for a 150-lb adult should return roughly 100–150 calories across both tools. Discrepancies >25% usually indicate different MET assumptions rather than a formula error.
