Scrubbing floors, tiles, and countertops is a surprisingly effective way to get your heart rate up while you check chores off your list. This calculator estimates how many calories you burn per hour of scrubbing based on your body weight, the intensity of your effort, and how much time you spend at it. It uses the standard metabolic equivalent (MET) values published in the Compendium of Physical Activities, so the numbers are grounded in real exercise science.
Whether you are deep-cleaning the bathroom, scrubbing a stubborn kitchen floor, or just wondering how your weekend cleaning session stacks up against a walk, this tool gives you a clear, personalized estimate. Simply enter your weight, choose an intensity level, and adjust the duration slider to see your total calories, per-minute burn, and how your effort compares to other gentle activities. It is perfect for anyone tracking daily movement, planning a cleaning workout, or simply curious about the hidden fitness value of household chores.
🧽 Scrubbing Calories Per Hour
How to Use This Tool
Using the scrubbing calorie calculator is straightforward. Start by entering your body weight in either kilograms or pounds — the calculator automatically converts pounds to kilograms for the formula. Next, select the intensity that best matches your cleaning style: light for gentle wiping and slow, easy strokes; moderate for steady, normal-paced scrubbing that gets you slightly breathless; or vigorous for fast, hard scrubbing that raises your heart rate noticeably. Finally, adjust the duration slider from 5 minutes up to 4 hours to see how your total burn changes with time.
Press Calculate to see your total calories burned, your per-minute rate, and your per-hour rate. The breakdown also shows the MET value used and the exact formula, so you can verify the math or adapt it to your own tracking spreadsheet.

How It Works
This calculator uses the standard metabolic equivalent (MET) method, which is the most widely accepted way to estimate energy expenditure for physical activities. One MET is the energy cost of sitting quietly, roughly 1 kcal per kilogram of body weight per hour. The Compendium of Physical Activities assigns MET values to hundreds of activities, including household chores.
For scrubbing, the compendium lists values around 3.0 METs for light effort, 3.5 METs for moderate effort, and 4.5 METs for vigorous effort. The formula used here is:
Calories per minute = MET × 3.5 × weight (kg) ÷ 200
The 3.5 represents the approximate oxygen consumption (in milliliters per kilogram per minute) at rest, and 200 converts the result into kilocalories. Multiply by your total minutes to get the full burn. This is the same formula used in most fitness trackers and exercise science textbooks, so your results will be consistent with other MET-based calculators.
Worked Examples
Example 1: A 70 kg person scrubs the bathroom floor at a moderate pace for 45 minutes. MET = 3.5. Calories per minute = 3.5 × 3.5 × 70 ÷ 200 = 4.29 kcal/min. Total = 4.29 × 45 = 193 kcal.
Example 2: A 150 lb person (about 68 kg) does a vigorous deep-clean for 90 minutes. MET = 4.5. Calories per minute = 4.5 × 3.5 × 68 ÷ 200 = 5.36 kcal/min. Total = 5.36 × 90 = 482 kcal.
Example 3: A 55 kg person does light wiping for 30 minutes. MET = 3.0. Calories per minute = 3.0 × 3.5 × 55 ÷ 200 = 2.89 kcal/min. Total = 2.89 × 30 = 87 kcal.
Tips & Best Practices
- Be honest about intensity. Most people underestimate how hard they are working. If you are breathing faster but can still hold a conversation, that is moderate. If you are sweating and breathing heavily, that is vigorous.
- Use a timer. It is easy to lose track of time while cleaning. Set a timer for each scrubbing session so your duration estimate is accurate.
- Break up long sessions. Scrubbing for 2 hours straight can strain your wrists and back. Take a 5-minute break every 30 minutes to stretch and reset your posture.
- Combine with other chores. Alternate scrubbing with sweeping, mopping, or vacuuming to keep your heart rate up and work different muscle groups. You can estimate those with our cleaning calories calculator.
- Track your progress. Log your daily cleaning calories alongside your workouts to see your total daily movement. Small efforts add up over a week.
Factors Affecting Accuracy
MET-based estimates are a useful guideline, but your actual calorie burn can vary by 10–20% or more depending on several factors. Your fitness level plays a role — people who are more conditioned often burn slightly fewer calories for the same task because their bodies work more efficiently. Your body composition matters too: muscle tissue burns more calories at rest than fat tissue, so two people of the same weight can have different metabolic rates.
Environmental factors also influence the burn. Scrubbing in a hot, humid room raises your heart rate and sweat rate, which can increase calorie expenditure. The type of surface matters as well — scrubbing a rough tile floor with a stiff brush requires more effort than wiping a smooth countertop. Finally, your technique and posture affect how much muscle you engage. Using your whole body rather than just your arms will increase the intensity and the calorie burn.
For the most accurate personal measurement, consider using a heart rate monitor or a fitness tracker with a built-in calorie algorithm. These devices use your actual heart rate data rather than a population average, giving you a more individualized estimate.
Frequently Asked Questions
Is scrubbing really a good workout?
Yes. Moderate scrubbing at 3.5 METs is comparable to a brisk walk (about 3.5–4 METs) or light cycling. A 70 kg person burns roughly 245 kcal per hour of moderate scrubbing, which is a meaningful contribution to your daily energy expenditure. It also works your arms, shoulders, core, and legs, especially if you squat or lunge while scrubbing low surfaces.
How many calories does 30 minutes of scrubbing burn?
For a 70 kg person, 30 minutes of moderate scrubbing burns about 122 kcal. Vigorous scrubbing would burn about 157 kcal, and light scrubbing about 105 kcal. Use the calculator with your own weight and intensity to get a personalized number.
Can I lose weight by cleaning?
Cleaning alone is unlikely to produce dramatic weight loss, but it can contribute to a calorie deficit when combined with a healthy diet and regular exercise. Burning an extra 200–300 kcal per day through household chores can add up to about 0.5 kg (1 lb) of fat loss per month, assuming your diet stays constant. It is a great way to add low-impact movement to your day without going to the gym.
What is the difference between this and the 30-minute scrubbing calculator?
This tool gives you a per-hour rate and lets you adjust the duration up to 4 hours, which is useful for long cleaning sessions or for comparing your burn to other hourly activities. The 30-minute scrubbing calculator is a quick snapshot for a standard half-hour session. Both use the same MET values, so results are consistent.
