Laundry day can be more of a workout than it seems. Sorting, folding, loading, and carrying baskets all keep you on your feet — and over 45 minutes, those small movements add up. This laundry calories per 45 minutes calculator gives you a personalized estimate of how much energy you burn during a typical laundry session, based on your body weight and how vigorously you work.
The calculator uses the standard MET (metabolic equivalent of task) formula, the same method used in exercise science to estimate calorie burn for everything from walking to cycling. Choose an effort level that matches your laundry routine — light folding, moderate loading, or vigorous carrying — and enter your weight to see your calories burned, plus your burn rate per 30 minutes and per hour.
This tool is ideal for anyone tracking daily movement, aiming for gentle activity goals, or curious about how household chores contribute to their overall calorie expenditure.

How the Calculator Works
The estimate is based on the standard MET (metabolic equivalent of task) formula used by exercise physiologists to convert an activity into calories burned. One MET is your resting energy expenditure, which is roughly 1 kcal per kilogram of body weight per hour. For any activity, the formula is:
The 3.5 and 200 are constants that express oxygen uptake in milliliters per kilogram per minute and convert that figure into calories. Because your body weight and the intensity of the task both appear in the equation, two people doing the same 45-minute laundry session can burn very different amounts. This is also why every bit of daily movement matters: although laundry is not as intense as running, it contributes to your non-exercise activity thermogenesis (NEAT), which is the energy you spend on everything that is not formal exercise, sleeping, or eating.
MET values in this calculator come from the widely used Compendium of Physical Activities. The light, moderate, and vigorous settings are representative ranges for typical laundry work, and the optional custom MET field lets you fine-tune the estimate if you have a more specific value.
MET Values for Laundry Tasks
MET values describe how many times more energy you expend than at rest. Here are the values used in this calculator:
| Laundry Activity | MET |
|---|---|
| Light effort — sorting, folding, hanging clothes | 2.3 |
| Moderate effort — loading/unloading washer or dryer, moving baskets | 3.0 |
| Vigorous effort — carrying heavy baskets, walking with loads | 3.8 |
To put these numbers in context, sitting quietly is about 1.0 MET, slow walking is about 2.8 MET, and cycling for pleasure is roughly 4.0 MET. That means vigorous laundry work can genuinely compare to a gentle walk in terms of energy expenditure, especially if you add stairs or heavy baskets to the mix.
Worked Examples
Example 1 — Moderate load, 70 kg person
MET = 3.0, weight = 70 kg
Calories = 3.0 × 3.5 × 70 ÷ 200 × 45 = 165.4 kcal
Example 2 — Light folding, 150 lb person
150 lb ÷ 2.2046 = 68.0 kg; MET = 2.3
Calories = 2.3 × 3.5 × 68.0 ÷ 200 × 45 = 123.2 kcal
Example 3 — Vigorous carrying, 85 kg person
MET = 3.8, weight = 85 kg
Calories = 3.8 × 3.5 × 85 ÷ 200 × 45 = 254.4 kcal
These examples show how both weight and effort level influence the final number. A heavier person always burns more for the same activity, and a higher MET value raises the estimate in direct proportion. The difference between light and vigorous laundry work in a 45-minute session can easily exceed 100 kcal.
Tips to Turn Laundry Into a Mini Workout
- Use a laundry basket and carry it around instead of leaving a pile on the floor.
- Take the stairs when moving clothes between floors — it raises your effort closer to vigorous.
- Add a few calf raises while folding to keep your leg muscles engaged.
- Speed up your folding pace during music tracks to add short intervals of higher intensity.
- Don't count every moment; only the time you are actively moving counts toward your total.
- If you have a wearable, aim to hit a step target during laundry day by making extra trips.
If you enjoy tracking gentle chores, you can also estimate calories for other routine activities — for example, you can check the Harvard calories burned chart to see how laundry compares with similar chores. For another 45-minute household activity, try the watering the garden calculator to keep your gentle movement tracking going.
Factors That Affect Accuracy
MET estimates are population averages, not personal measurements. Your actual calorie burn depends on your muscle mass, fitness level, age, and even how efficiently you move. A taller or heavier person will burn more; a highly trained person may burn slightly less because their body is more economical at a given task. The calculator also assumes you are continuously active for the full 45 minutes — stopping to check your phone or resting between loads reduces the total.
Environmental factors matter too. Doing laundry in a warm, humid room can increase your heart rate and sweat, but that extra work is mostly thermal strain rather than additional calorie burn from the task itself. Similarly, carrying a heavy hamper up two flights of stairs may push you above the vigorous MET value we use, while moving small items from a dryer to a table barely above light effort.
Use this estimate as a rough guide for daily movement tracking, not as a medical or weight-loss prescription. If you are aiming for a specific calorie deficit, combine the estimate with a food diary and, ideally, guidance from a qualified professional.
Frequently Asked Questions
Is laundry really a workout?
For most people, light household chores don't raise heart rate enough to be called "exercise," but they still contribute to your daily non-exercise activity thermogenesis (NEAT). At a vigorous pace, laundry can create meaningful calorie burn, especially for beginners or those recovering from injury. Over time, accumulating 30 to 60 minutes of light activity through chores can support general health and daily energy balance.
Should I count laundry time in my fitness app?
If your app allows custom activities, you can add "laundry" as a light aerobic activity using the MET value that matches your effort. Some apps already include household chores in their database. For a 45-minute session, entering the MET value manually is the most reliable way to avoid overestimating because default entries can be vague.
What is a MET?
MET stands for metabolic equivalent of task. One MET equals the energy you use at rest. Activity MET values come from research databases such as the Compendium of Physical Activities, and the MET concept is explained in more detail on Wikipedia. These values are designed for adults and should be interpreted as estimates, not precise measurements.
How many calories can 45 minutes of laundry burn?
For a typical adult, the answer is usually between 80 and 220 kcal, depending mainly on body weight and effort. Light folding may be closer to 90–120 kcal, while vigorous carrying with stairs can reach 200 kcal or more for heavier individuals. This reinforces that even routine chores can be a meaningful part of an active day.
