Free calories burned calculator for 100+ activities using 2024 Compendium MET values, with examples, walking pad numbers and why fitness watches often differ.
Key takeaways
- The 2024 Adult Compendium lists 1,114 activities for ages 19 to 59, most with lab-measured MET values.[1]
- One MET is about 1 calorie per kilogram of body weight per hour.[3]
- None of seven popular wrist devices estimated calories burned with an error below 20% in a lab study.[4]
- 150 to 250 minutes a week of moderate activity brings only modest weight loss on its own; combining activity with eating changes does more.[5]
In short: This calories burned calculator estimates the energy you use in more than 100 activities, from walking and swimming to gardening and dancing. It multiplies the activity’s MET value from the Compendium of Physical Activities by your weight and the time you spend. Heavier bodies and harder efforts burn more. The result is a fair average for adults, not an exact count for you.

How this works
Each activity has a MET value (metabolic equivalent): how many times more energy it uses than sitting still. 1 MET is about 1 calorie per kilogram of body weight per hour.
Calories burned = MET × weight in kg × hours. "Above resting" subtracts the 1 MET you would burn anyway.
Limits
- MET values are averages for adults; fitness, technique, terrain, heat and effort change the real number.
- Fitness watches and gym machines often show higher numbers than these estimates.
- Exercise helps most with keeping weight off and with health; on its own it usually causes a modest loss.

Where the numbers come from
The Compendium of Physical Activities is the reference researchers use to put an energy cost on everyday activities. It was first published in 1993 and has been updated three times. The latest edition, the 2024 Adult Compendium, lists 1,114 activities for adults aged 19 to 59, most of them with values measured in the lab rather than estimated; a separate Older Adult Compendium covers people 60 and over. One MET equals about 1 calorie per kilogram of body weight per hour, the energy of sitting quietly, so an activity of 4 METs uses about four times that.

Examples: 30 minutes of common activities
MET values from the 2024 Adult Compendium; totals include resting energy and are rounded.
| Activity (Compendium code) | MET | 155 lb (70 kg) | 200 lb (91 kg) |
|---|---|---|---|
| Hatha yoga (02150) | 2.3 | about 81 cal | about 104 cal |
| Weight training, 8-15 reps (02054) | 3.5 | about 123 cal | about 159 cal |
| Walking, 2.8-3.4 mph (17190) | 3.8 | about 134 cal | about 172 cal |
| Gardening, moderate effort (08245) | 3.8 | about 134 cal | about 172 cal |
| Walking, 3.5-3.9 mph, brisk (17200) | 4.8 | about 169 cal | about 218 cal |
| Elliptical, moderate effort (02048) | 5.0 | about 176 cal | about 227 cal |
| Swimming laps, freestyle, slow (18240) | 5.8 | about 204 cal | about 263 cal |
| Cycling, 12-13.9 mph (01030) | 8.0 | about 281 cal | about 363 cal |
| Running, 6-6.3 mph (12050) | 9.3 | about 327 cal | about 422 cal |
Small activities add up too. For a 155-pound person, a 30-minute brisk walk (4.8 METs), 20 minutes of gardening (3.8) and 10 minutes of climbing stairs at a slow pace (4.5) together use roughly 310 calories, about 240 of them above what sitting would have used.
Walking pads and treadmill desks
Slow walking while you work adds up over a day. The 2024 Compendium gives 2.0 METs for a treadmill desk at 1 mph or less and 2.8 METs at 1 to 2 mph; a regular treadmill at 2.5 to 2.9 mph is 3.5 METs and 3.0 to 3.4 mph is 3.8. For comparison, sitting at a computer and typing at a standing desk are both 1.3 METs, so standing alone burns little extra; it is the walking that counts. An hour at 1 to 2 mph comes to roughly 200 calories for a 155-pound person. Our guide to walking pads compares models, and the walking guide has a plan to build up.
| Item | Value |
|---|---|
| Sitting, computer work | 1.3 |
| Standing desk, typing | 1.3 |
| Treadmill desk, 1 mph or less | 2 |
| Treadmill desk, 1-2 mph | 2.8 |
| Treadmill, 2.5-2.9 mph | 3.5 |
| Treadmill, 3.0-3.4 mph | 3.8 |
1 MET is about the energy of sitting quietly; standing adds little, walking adds more.

Why your watch may show a different number
Fitness watches and gym machines estimate calories from heart rate and movement, and they are often off. In a Stanford study of seven popular wrist devices tested against lab measurements, none estimated energy use with an error below 20%, even though most measured heart rate well. Errors were larger for walking. Use any device’s calorie number to compare your own days, not as a figure to eat back.
Exercise and weight loss: what to expect
Activity is great for health, mood and keeping weight off, but on its own it usually brings modest weight loss. The American College of Sports Medicine found that 150 to 250 minutes a week of moderate activity produces only modest loss, with more activity, or activity combined with eating changes, doing more. The U.S. Physical Activity Guidelines recommend at least 150 to 300 minutes of moderate activity a week plus strength work on two or more days. Pick activities you enjoy, because the one you keep doing burns the most over a year. Our exercise hub covers options for every fitness level, including strength training.
Using the result in your plan
Your daily activity level already feeds into the calorie calculator and the TDEE calculator, so you do not need to add exercise twice. Use this tool to compare activities, to see what a new habit adds, or to understand why a plateau happened when your routine changed.

Frequently asked questions
How many calories does walking burn?
It depends on speed and your weight. At 2.8 to 3.4 mph (3.8 METs), a 155-pound person burns about 134 calories in 30 minutes, and a 200-pound person about 172.
Does the calculator include the calories I would burn anyway?
The main result is the total for the activity, including resting energy. The "above resting" figure subtracts the 1 MET you would use sitting still, which is the extra the activity adds.
Are MET values accurate for older adults?
The 2024 Adult Compendium is built for ages 19 to 59. A separate Older Adult Compendium covers people 60 and over, and values can differ.
Should I eat back the calories I burn?
If you used an activity level in a calorie calculator, your usual exercise is already counted. Extra exercise can be partly eaten back while you watch your weight trend.
