Laundry might not feel like a workout, but folding, sorting, and carrying clothes actually burns a surprising number of calories. This calculator estimates how many calories you burn during 15 minutes of laundry tasks, based on your body weight and the intensity of the activity. Whether you're folding a few shirts or hauling heavy baskets up and down stairs, you'll get a realistic estimate tailored to your effort level.
Use this tool to track your daily movement, add up your household activity, or simply satisfy your curiosity about how much energy everyday chores require. It's perfect for anyone interested in gentle movement, low-impact exercise, or just making the most of their daily routine. Enter your weight, choose your task intensity, and hit calculate to see your results instantly.

How to Use This Tool
Using the laundry calorie calculator is simple. Start by entering your body weight in either kilograms or pounds — the calculator will automatically convert if needed. Then select the intensity level that best matches your laundry task: light for folding and sorting, moderate for carrying baskets and loading the machine, or vigorous for hauling heavy loads up stairs or scrubbing stains. Click "Calculate" to see your estimated calorie burn for a 15-minute session, along with a breakdown showing the MET value and calories per minute.
For quick reference, use the preset weight buttons to fill in common weights instantly. The reset button clears all fields and results, so you can start fresh with a new scenario. This tool is designed for anyone curious about the energy cost of everyday chores, whether you're tracking daily movement or just exploring gentle exercise options.
How It Works
The calculation uses the standard metabolic equivalent (MET) formula, which estimates energy expenditure based on the intensity of an activity. MET values represent how many times more energy you burn compared to resting. For laundry tasks, we use the following MET values:
- Light (folding, sorting): 2.3 METs
- Moderate (carrying baskets, loading): 3.3 METs
- Vigorous (hauling, stairs, scrubbing): 4.0 METs
The formula is: Calories per minute = (MET × 3.5 × weight in kg) / 200. Then multiply by 15 minutes to get the total. This method is widely used in exercise science and is the basis for many fitness trackers and calorie databases.
Worked Examples
Example 1: A 70 kg person folding laundry (light intensity). Calories per minute = (2.3 × 3.5 × 70) / 200 = 2.82 kcal/min. In 15 minutes, they burn about 42.3 calories.
Example 2: A 150 lb person (about 68 kg) carrying heavy baskets (moderate intensity). Calories per minute = (3.3 × 3.5 × 68) / 200 = 3.93 kcal/min. In 15 minutes, they burn about 58.9 calories.
Example 3: A 90 kg person hauling laundry up and down stairs (vigorous intensity). Calories per minute = (4.0 × 3.5 × 90) / 200 = 6.3 kcal/min. In 15 minutes, they burn about 94.5 calories.
Tips & Best Practices
- Be honest about your intensity level — it's easy to overestimate effort, which can skew results.
- If you're doing a mix of tasks, average the intensity or calculate each segment separately.
- Use this calculator as part of a broader activity log. Even small chores add up over the day.
- Remember that individual metabolism varies, so treat the result as an estimate, not an exact number.
Factors Affecting Accuracy
Several factors can influence your actual calorie burn. Your body composition, fitness level, and even the temperature of your environment play a role. The MET values used here are averages from research studies and may not perfectly match your personal physiology. Additionally, the calculator assumes a steady pace; if you take frequent breaks, your burn will be lower. For the most accurate tracking, consider using a heart rate monitor or fitness tracker that accounts for your individual data.
Frequently Asked Questions
Can laundry really count as exercise? Yes, especially if you're moving briskly and carrying heavy loads. It's a form of low-impact activity that contributes to your daily movement goals.
How many calories do I burn doing laundry for an hour? Multiply the 15-minute result by 4. For example, a 70 kg person doing light laundry burns about 42 calories per 15 minutes, so about 169 calories per hour.
Does the calculator work for other chores? The MET values are specific to laundry, but similar activities like folding clothes or carrying baskets have comparable energy costs. For other chores, check out our chopping calories calculator or groceries calories calculator.
Why is my result different from my fitness tracker? Fitness trackers use additional data like heart rate and movement patterns, which can make them more or less accurate depending on the device. This calculator provides a standardized estimate based on weight and intensity.
