Ever wonder how many calories you burn while doing laundry? This calculator estimates the calories burned during 30 minutes of laundry-related activities, from sorting and folding to carrying baskets and loading the machine. It uses the Metabolic Equivalent of Task (MET) values from the Compendium of Physical Activities to give you a personalized estimate based on your weight and the intensity of your chores.
Whether you're curious about your daily movement, tracking your overall activity, or just want to see how household tasks add up, this tool is for you. Simply enter your weight, choose the activity and intensity, and hit calculate. You'll get an estimate for 30 minutes, plus a breakdown of calories per minute and per hour.
Laundry may not be a workout, but it's real movement — and every bit counts toward your daily energy expenditure. Use this calculator to appreciate the gentle activity hidden in your routine.

📊 Calculation Breakdown
How to Use This Tool
Using the laundry calorie calculator is straightforward. Start by entering your body weight in either kilograms or pounds — the calculator will convert automatically if needed. Next, select the specific laundry activity you're doing from the dropdown: sorting and folding, loading/unloading the machine, carrying laundry baskets, hanging clothes, or ironing. Then choose an intensity level that matches how briskly you're moving: light (slow, relaxed), moderate (steady, purposeful), or vigorous (fast, energetic).
After clicking Calculate, you'll see your estimated calories burned for 30 minutes, along with per-minute and per-hour rates. The breakdown section shows the exact formula used, so you can understand how the number was derived. You can also use the quick-fill buttons to instantly populate common weights, making it easy to compare different scenarios.
How It Works
This calculator uses the Metabolic Equivalent of Task (MET) method, a standard approach in exercise science. One MET is the energy cost of sitting quietly, roughly 1 kcal per kilogram of body weight per hour. Physical activities are assigned MET values based on research from the Compendium of Physical Activities.
The formula is:
Calories per minute = MET × 3.5 × weight (kg) ÷ 200
For example, a 70 kg person doing moderate laundry work (MET 3.0) would burn:
3.0 × 3.5 × 70 ÷ 200 = 3.675 kcal/min
In 30 minutes: 3.675 × 30 = 110.25 kcal
The MET values used here are based on typical household chores. Sorting and folding is generally light (2.3 MET), while carrying baskets can be more vigorous (up to 4.0 MET). These values are estimates — your actual burn depends on your unique physiology and how efficiently you move.
Worked Examples
Let's walk through a few scenarios to illustrate how the calculator works.
Example 1: A 60 kg person folding laundry at a light pace (MET 2.3).
Calories per minute = 2.3 × 3.5 × 60 ÷ 200 = 2.415 kcal/min
In 30 minutes: 2.415 × 30 = 72.45 kcal
Example 2: A 180 lb (81.6 kg) person carrying laundry baskets vigorously (MET 4.0).
Weight in kg = 180 × 0.4536 = 81.6 kg
Calories per minute = 4.0 × 3.5 × 81.6 ÷ 200 = 5.712 kcal/min
In 30 minutes: 5.712 × 30 = 171.36 kcal
Example 3: A 75 kg person ironing at moderate intensity (MET 2.8).
Calories per minute = 2.8 × 3.5 × 75 ÷ 200 = 3.675 kcal/min
In 30 minutes: 3.675 × 30 = 110.25 kcal
Tips & Best Practices
- Be honest about intensity. If you're moving slowly and taking breaks, choose 'light'. If you're rushing to get laundry done before work, 'vigorous' might be more accurate.
- Use your actual weight. The estimate scales linearly with weight, so a small error in weight can shift the result noticeably.
- Combine with other chores. Laundry is just one part of household movement. You can also estimate calories for mopping or vacuuming to get a fuller picture of your daily activity.
- Track over time. If you do laundry several times a week, multiply your 30-minute result by the number of sessions to see your weekly contribution.
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, so individuals with more muscle may burn slightly more.
- Age and fitness: Younger, fitter people often have higher metabolic rates.
- Movement efficiency: Experienced laundry-doers may move more efficiently, burning fewer calories for the same task.
- Environmental factors: Hot, humid conditions can increase heart rate and calorie burn.
These estimates are best used as a general guide, not a precise measurement. For weight management, focus on overall daily activity and diet rather than obsessing over exact numbers.
Frequently Asked Questions
Can doing laundry really help with weight loss?
Yes, but the effect is modest. A 30-minute session might burn 70–170 kcal depending on your weight and intensity. Over a week, that could add up to 500–1000 kcal — roughly equivalent to one or two extra workouts. It's not a substitute for dedicated exercise, but it's a nice bonus.
What's the difference between light, moderate, and vigorous laundry?
Light means slow, relaxed movements with frequent pauses. Moderate is steady, purposeful work without rushing. Vigorous is fast, energetic movement — like trying to finish before a timer goes off. The MET values increase accordingly, reflecting higher energy expenditure.
Why does the calculator ask for weight in kg or lb?
The formula uses kilograms, but many people think in pounds. The calculator converts pounds to kilograms automatically (1 lb = 0.4536 kg), so you can use whichever unit you prefer.
Is this calculator suitable for all ages?
Yes, the MET formula works for adults of any age. For children and teenagers, metabolic rates can differ, but the estimate is still a reasonable approximation. Always consult a healthcare provider before starting any new exercise routine.
