Ironing might not feel like a workout, but it's a steady, low-intensity activity that burns more calories than you'd think. This calculator estimates how many calories you burn during a 15-minute ironing session based on your body weight and the effort you put in. Whether you're tackling a pile of shirts or just doing a quick touch-up, knowing your energy expenditure can help you track your daily activity and gentle movement goals.
Using the standard MET (Metabolic Equivalent of Task) values for ironing, the tool applies a widely accepted formula to give you a personalized estimate. You can choose between light, moderate, and vigorous effort levels, and even adjust the session length if you want to see results for a different duration. It's perfect for anyone curious about the calorie cost of household chores, fitness enthusiasts tracking total daily burn, or those building a more active lifestyle with everyday tasks.

How to Use This Tool
Enter your body weight (in kilograms or pounds), select the effort level that matches your ironing pace, and adjust the session length if you want to calculate for a different duration. The default is 15 minutes, but you can change it to any value from 1 to 240 minutes. Click Calculate to see your estimated calorie burn, along with a breakdown of the formula. Use the quick-fill buttons to instantly load common weights (60 kg, 70 kg, 80 kg, or 155 lb) if you don't want to type.
The result shows the total calories burned, the MET value used, and the step-by-step math so you can understand exactly how the estimate was derived. This transparency helps you trust the number and adjust your expectations based on your own effort.
How It Works
This calculator uses the standard metabolic equivalent (MET) method, which is widely used in exercise science to estimate energy expenditure. One MET is the energy cost of sitting quietly, roughly 1 kcal per kilogram of body weight per hour. The formula is:
Calories per minute = MET × 3.5 × (weight in kg) ÷ 200
For ironing, the Compendium of Physical Activities assigns MET values of approximately 2.3 for light effort, 2.8 for moderate effort, and 3.3 for vigorous effort. These values reflect the average energy cost of the activity for a typical adult. The calculator multiplies the per-minute burn by your session length to get the total.
Because the MET values are averages, your actual burn can vary based on factors like your muscle mass, how quickly you move the iron, whether you're standing or sitting, and even the temperature of the room. Still, the estimate is a reliable baseline for tracking daily activity.
Worked Examples
Example 1: A 70 kg person does 15 minutes of moderate ironing. MET = 2.8. Calories per minute = 2.8 × 3.5 × 70 ÷ 200 = 3.43 kcal/min. Total = 3.43 × 15 = 51.5 kcal.
Example 2: A 155 lb (70.3 kg) person does 30 minutes of vigorous ironing. MET = 3.3. Calories per minute = 3.3 × 3.5 × 70.3 ÷ 200 = 4.06 kcal/min. Total = 4.06 × 30 = 121.8 kcal.
Example 3: A 50 kg person does 15 minutes of light ironing. MET = 2.3. Calories per minute = 2.3 × 3.5 × 50 ÷ 200 = 2.01 kcal/min. Total = 2.01 × 15 = 30.2 kcal.
Tips & Best Practices
- Be honest about your effort level. If you're ironing slowly while watching TV, choose light. If you're moving quickly and purposefully, choose vigorous.
- Use a kitchen scale or bathroom scale to get an accurate weight. Even a 5 kg difference can change your estimate by several calories.
- Ironing is a low-intensity activity, so don't expect dramatic calorie burns. Instead, think of it as part of your daily non-exercise activity thermogenesis (NEAT).
- To increase the burn, stand rather than sit, use a taller ironing board, and keep a steady rhythm. You can also add arm movements or do small calf raises while ironing.
- Track your total daily steps and other chores to see how household tasks contribute to your overall energy expenditure.
Factors Affecting Accuracy
The MET values are based on averages from research studies, but individual differences matter. Your age, gender, body composition, and fitness level all influence how many calories you actually burn. A person with more muscle mass will burn slightly more, while someone who is very efficient at ironing may burn less because they use less energy per motion.
Also, the calculator assumes you are actively ironing for the entire duration. If you pause frequently to adjust clothes or take breaks, your actual burn will be lower. For the most accurate estimate, use a heart rate monitor or a fitness tracker that accounts for your personal physiology, but for most purposes, this MET-based calculation is perfectly adequate.
Frequently Asked Questions
Is ironing really exercise?
Ironing is considered a light-intensity daily activity, not formal exercise. It raises your heart rate slightly and burns a modest number of calories, but it won't improve cardiovascular fitness on its own. However, accumulating many such activities throughout the day can contribute to your overall energy balance and help you stay active.
How many calories do I burn ironing for 30 minutes?
For a 70 kg person, moderate ironing burns about 3.43 kcal/min, so 30 minutes would burn roughly 103 kcal. Use the calculator with a duration of 30 to get a personalized number.
Can I lose weight by ironing?
Weight loss requires a calorie deficit, and ironing alone burns too few calories to create a significant deficit. But every bit helps. If you iron for 30 minutes daily, that's about 700–800 kcal per week, which could contribute to a small weekly deficit when combined with other healthy habits.
What is the MET value for ironing?
The Compendium of Physical Activities lists ironing at 2.3 METs for light effort, 2.8 for moderate, and 3.3 for vigorous. These are the values used in this calculator.
