Estimate calories and kilojoules burned house cleaning — dusting and tidying, vacuuming, mopping and sweeping, and scrubbing floors — based on your body weight, effort level, and session duration. Cleaning is one of the most common household tasks around, something most people do regularly whether they think of it as "exercise" or not, and it genuinely burns calories once the effort level moves beyond light tidying — it's one of the more overlooked forms of incidental physical activity built into everyday life.
House cleaning calorie burn depends heavily on how physically demanding the task is, captured here as three tiers: light cleaning (MET 2.5), moderate cleaning — vacuuming, mopping, sweeping (MET 3.5), and vigorous cleaning — scrubbing floors (MET 6.5). The formula is calories = MET × body weight (kg) × duration (hours). A 70 kg person cleaning for 45 minutes burns 131 kcal (about 549 kJ) at light effort, 184 kcal (about 769 kJ) at moderate effort, and 341 kcal (about 1,428 kJ) at vigorous effort — well over twice as much energy burned scrubbing floors compared with light cleaning.
| Effort Level | MET | Calories | Kilojoules |
|---|
The calculation uses a MET (Metabolic Equivalent of Task) value for your cleaning effort level, your body weight, and the duration of your session. This calculator uses three MET tiers taken directly from the Household Activities codes in the 2024 Adult Compendium of Physical Activities — light cleaning (code 05040, "cleaning, general (straightening up, changing linen, carrying out trash), light effort", MET 2.5), moderate cleaning (code 05021, "cleaning, mopping, standing, moderate effort", MET 3.5), used here to represent standing tasks such as vacuuming, mopping and sweeping, and vigorous cleaning (code 05132, "scrubbing floors, on hands and knees, scrubbing bathroom, bathtub, vigorous effort", MET 6.5). None of these three codes are flagged as estimated in the Compendium — all three are literature-supported entries.
| Effort Level | MET | Calories (70 kg, 45 min) | Kilojoules |
|---|---|---|---|
| Light cleaning | 2.5 | 131 kcal | 549 kJ |
| Moderate cleaning (vacuuming, mopping, sweeping) | 3.5 | 184 kcal | 769 kJ |
| Vigorous cleaning (scrubbing floors) | 6.5 | 341 kcal | 1,428 kJ |
House cleaning covers a surprisingly wide range of physical effort, which is exactly why this calculator uses three separate tiers rather than a single number. Light cleaning covers general straightening up — dusting shelves, tidying rooms, making beds, changing linen, wiping surfaces and carrying out the rubbish. It's genuinely low-intensity, comparable to pottering around the house. Moderate cleaning steps up to sustained standing tasks done at a steady working pace — vacuuming carpets and floors, mopping hard floors, and sweeping — all of which keep you moving continuously around the house rather than in short bursts. Vigorous cleaning is the most demanding tier, covering scrubbing floors on hands and knees and scrubbing a bathroom or bathtub — this genuinely calls on upper-body and core effort in a way that dusting and vacuuming simply don't, which is why it burns substantially more energy per minute than the other two tiers.
Cleaning can genuinely contribute to physical activity, and the effort tiers above give a sense of why — moderate and vigorous cleaning sit in a similar intensity range to other activities widely recognised as moderate-to-vigorous physical activity. Whether a given cleaning session counts towards a particular physical activity guideline or weekly target depends on the intensity and duration involved, and general population physical activity guidelines are published by the Australian Government Department of Health and by the World Health Organization. This calculator provides a general estimate of energy expenditure only — it isn't personalised health advice, so anyone wanting to know how cleaning fits into a specific health or fitness plan should refer to official guidelines or speak with a healthcare professional.
The table below holds effort level constant at the moderate tier (MET 3.5) for a 45-minute session, so you can see how much body weight alone changes the total.
| Body Weight | MET | Calories (45 min) | Kilojoules |
|---|---|---|---|
| 55 kg | 3.5 | 144 kcal | 604 kJ |
| 65 kg | 3.5 | 171 kcal | 714 kJ |
| 70 kg | 3.5 | 184 kcal | 769 kJ |
| 75 kg | 3.5 | 197 kcal | 824 kJ |
| 85 kg | 3.5 | 223 kcal | 934 kJ |
| 95 kg | 3.5 | 249 kcal | 1,043 kJ |
Here body weight is fixed at 70 kg while both session length and effort level change, so you can compare how much a harder tier and a longer session each add to the total.
| Duration | Light (MET 2.5) | Moderate (MET 3.5) | Vigorous (MET 6.5) |
|---|---|---|---|
| 30 minutes | 88 kcal / 366 kJ | 123 kcal / 513 kJ | 228 kcal / 952 kJ |
| 45 minutes | 131 kcal / 549 kJ | 184 kcal / 769 kJ | 341 kcal / 1,428 kJ |
| 60 minutes | 175 kcal / 732 kJ | 245 kcal / 1,025 kJ | 455 kcal / 1,904 kJ |
Australian nutrition panels list energy in kilojoules, not calories, so it's worth converting your session into the same unit your food packaging uses. Multiply your calorie figure by 4.184 to get kilojoules. A 70 kg person cleaning at moderate effort for 45 minutes burns about 184 kcal, which is roughly 769 kJ — a useful figure to weigh up against the energy value printed on a post-cleaning snack or drink.
How many calories does cleaning burn?
It depends on effort level. A 70 kg person cleaning for 45 minutes burns around 131 kcal at light cleaning (MET 2.5), around 184 kcal at moderate cleaning — vacuuming, mopping, sweeping (MET 3.5), and around 341 kcal at vigorous cleaning — scrubbing floors (MET 6.5). Lighter or heavier people, and longer or shorter sessions, will see proportionally lower or higher numbers, so use the calculator above with your own weight and duration for a personalised estimate.
How is calories burned cleaning calculated?
The calculator multiplies a MET (Metabolic Equivalent of Task) value for your chosen cleaning effort level by your body weight in kilograms and by your session duration in hours: calories = MET × body weight (kg) × duration (hours). The three MET values used — 2.5 for light cleaning, 3.5 for moderate cleaning, and 6.5 for vigorous cleaning — come directly from the 2024 Adult Compendium of Physical Activities. The result in kilocalories is then multiplied by 4.184 to give the equivalent figure in kilojoules, the unit used on Australian food labels.
Why are vacuuming and mopping considered "moderate" exercise?
Vacuuming, mopping and sweeping all involve sustained standing movement around the house at a steady working pace, rather than the occasional reach-and-tidy motion of light cleaning. That continuous, whole-body movement — walking, pushing, reaching, bending — is what pushes the MET value up to 3.5, a similar intensity range to other activities generally regarded as moderate physical activity, such as a brisk walk.
Why does scrubbing floors burn so much more than vacuuming?
Scrubbing floors on hands and knees uses MET 6.5, compared with MET 3.5 for standing tasks like vacuuming and mopping, because it adds genuine upper-body and core effort — pressing down, scrubbing repeatedly, and holding a braced hands-and-knees position — on top of the movement around the room. That extra muscular effort is what very nearly doubles the calorie burn per minute compared with the moderate tier, and makes it the most demanding of the three tiers by a clear margin.
Does cleaning count toward weekly exercise guidelines?
Moderate and vigorous cleaning sit in a similar intensity range to other activities widely recognised as moderate-to-vigorous physical activity, so a cleaning session can genuinely contribute to overall activity levels. Whether a specific session counts towards a particular guideline or target depends on the intensity and duration involved. This calculator gives a general energy-expenditure estimate only, not personalised health advice — for guidance on physical activity targets, refer to official sources such as the Australian Government Department of Health, or speak with a healthcare professional.
How does a full weekly clean add up?
It adds up faster than most people expect. If a typical week includes, say, one 45-minute moderate-effort session (vacuuming and mopping) at around 184 kcal, plus a shorter vigorous scrub of the bathroom, plus some daily light tidying, the moderate session alone already accounts for close to 200 kcal before anything else is counted. Running each portion of your actual cleaning routine through the calculator above and adding the results together gives a more accurate picture of your total weekly cleaning-related energy expenditure than any single flat estimate.
How does cleaning compare to a dedicated workout?
It depends entirely on the intensity. Light cleaning (MET 2.5) is closer to a slow household task than a workout, moderate cleaning (MET 3.5) is broadly comparable in intensity to a brisk walk or light general exercise, and vigorous cleaning such as scrubbing floors (MET 6.5) sits close to a genuinely vigorous workout in terms of MET value. The main practical difference is that cleaning intensity naturally varies throughout a session — vacuuming for ten minutes, then pausing to tidy, then scrubbing a bathroom — whereas a structured workout more often holds a consistent effort level throughout.
Does body weight change how many calories cleaning burns?
Yes. Because calories equal MET multiplied by body weight in kilograms multiplied by duration in hours, body weight is a direct multiplier in the formula. At the moderate effort tier for a 45-minute session, an 85 kg person burns roughly 223 kcal compared with about 144 kcal for a 55 kg person completing the identical session at the identical effort level.
How do I convert calories burned cleaning into kilojoules?
Multiply the calorie figure by 4.184, the standard conversion between kilocalories and kilojoules used on Australian food labels. A 70 kg person cleaning at moderate effort for 45 minutes burns about 184 kcal, which converts to roughly 769 kJ — a useful number to weigh against the energy value on a post-cleaning snack or drink.
