Ever wonder how many calories you burn while sorting, folding, and carrying laundry? This calculator estimates the calories burned during 25 minutes of laundry-related activity, based on your weight and the intensity of the task. Whether you're doing light folding or hauling heavy baskets up stairs, you'll get a personalized estimate using the standard MET (Metabolic Equivalent of Task) method.
Simply enter your weight, choose your activity intensity, and optionally adjust the duration if you want to see results for a different time frame. The calculator provides your total calories burned, plus a breakdown of calories per minute and per hour, so you can compare laundry to other gentle movements like walking or yoga. Perfect for anyone tracking daily activity, building a movement habit, or just curious about the energy cost of household chores.

How to Use This Tool
Using the calculator is straightforward. Start by entering your body weight in kilograms or pounds — the calculator automatically converts to kilograms for the formula. Then select the intensity that best matches your laundry activity:
- Light — folding clothes, sorting socks, hanging items on a rack. This is low-effort, mostly standing or sitting.
- Moderate — carrying laundry baskets, loading and unloading the washer or dryer, moving clothes from one room to another. This involves some walking and lifting.
- Vigorous — hauling heavy wet laundry, carrying multiple baskets up and down stairs, or moving large loads quickly. This raises your heart rate noticeably.
Adjust the duration if you want to estimate for a different time period — the default is 25 minutes, but you can enter any value from 1 to 300 minutes. Click Calculate to see your total calories burned, plus a per-minute and per-hour breakdown. Use the quick-fill buttons to instantly populate common weights.
How It Works
The estimate uses the MET (Metabolic Equivalent of Task) method, which is the standard approach in exercise science for estimating energy expenditure. One MET equals the energy you burn at rest — roughly 1 kcal per kilogram of body weight per hour. The formula is:
Calories per minute = (MET × 3.5 × weight in kg) / 200
This formula comes from the MET concept and is widely used in fitness trackers and research studies. The MET values for laundry are based on the Compendium of Physical Activities, a comprehensive list of activity intensities compiled by researchers. For light laundry (folding, sorting), the MET is about 2.3; for moderate laundry (carrying baskets, loading/unloading), it's about 3.3; and for vigorous laundry (hauling heavy loads, stairs), it's about 4.0.
To illustrate, a 70 kg person doing moderate laundry for 25 minutes would burn: (3.3 × 3.5 × 70) / 200 = 4.04 kcal per minute, or about 101 kcal total. That's roughly equivalent to a brisk 20-minute walk.
Worked Examples
Example 1: A 60 kg person does light laundry (folding) for 25 minutes. Calories per minute = (2.3 × 3.5 × 60) / 200 = 2.415 kcal. Total = 2.415 × 25 = 60.4 kcal.
Example 2: A 80 kg person does vigorous laundry (hauling baskets up stairs) for 25 minutes. Calories per minute = (4.0 × 3.5 × 80) / 200 = 5.6 kcal. Total = 5.6 × 25 = 140 kcal.
Example 3: A 155 lb (70.3 kg) person does moderate laundry for 30 minutes. Calories per minute = (3.3 × 3.5 × 70.3) / 200 = 4.06 kcal. Total = 4.06 × 30 = 121.8 kcal.
Tips & Best Practices
- Be honest about intensity. If you're mostly folding while watching TV, choose light. If you're actively moving baskets and bending, choose moderate. Overestimating intensity will inflate your calorie count.
- Use a fitness tracker. Many trackers have a "housework" or "chores" mode. Compare its reading with this calculator to get a sense of your personal burn rate.
- Turn laundry into a mini-workout. Add extra trips up and down stairs, do a few calf raises while folding, or speed up your pace. Small changes can increase the MET value and your calorie burn.
- Combine with other gentle activities. Laundry is a great complement to walking or yoga. For example, you could do 25 minutes of laundry and then a 20-minute walk to accumulate more movement throughout the day.
Factors Affecting Accuracy
Several factors can make your actual calorie burn differ from the estimate:
- Body composition: Muscle burns more calories than fat at rest and during activity. A person with more muscle mass may burn slightly more.
- Age and fitness level: Younger, fitter individuals often have a higher metabolic rate, but they may also move more efficiently, which can reduce energy cost.
- Environmental factors: Carrying laundry up stairs burns more than on flat ground. Hot, humid conditions can increase heart rate and perceived effort.
- Individual variation: The MET formula is an average. Your personal burn could be 10-20% higher or lower.
For the most accurate tracking, consider using a heart rate monitor or a fitness tracker that accounts for your heart rate. This calculator is best used as a consistent reference point for comparing different days and activities.
Frequently Asked Questions
Is laundry really exercise? Yes, especially if you're moving heavy loads or climbing stairs. It's considered low-impact, gentle movement that contributes to your daily activity. The CDC recommends at least 150 minutes of moderate-intensity activity per week, and laundry can count toward that if you're moving briskly.
How does laundry compare to walking? Moderate laundry (MET 3.3) is similar to walking at 3 mph (MET 3.5). Vigorous laundry (MET 4.0) is comparable to brisk walking at 3.5-4 mph. So a 25-minute laundry session can be roughly equivalent to a 20-25 minute walk.
Can I lose weight by doing laundry? It can help, but it's not a substitute for dedicated exercise. Burning an extra 100-150 kcal per day through chores like laundry can contribute to a calorie deficit over time, especially when combined with a healthy diet.
Why is the MET value different for light vs. vigorous? MET values are based on research measuring oxygen consumption during specific tasks. Heavier lifting and faster movement require more energy, hence higher MET values. The Compendium of Physical Activities provides these standardized values.
