Calories Burned Calculator
Calories Burned Calculator: Estimate Calories for Any Activity
A calories burned calculator estimates how much energy your body uses during exercise and everyday movement. Choose an activity, enter how long you did it and your body weight, and this free tool shows the total calories burned, the rate per minute and per hour, the net calories above resting, and how the same session compares with walking, cycling and running. With 48 activities from walking and yoga to swimming, sports and jumping rope, it works as a simple exercise calorie calculator for workouts of any length.
Quick answer: a 70 kg person who runs at 8 km/h (5 mph) for 30 minutes burns about 291 calories, or 581 calories per hour. About 256 of those are net calories, the extra energy above what the body would use at rest anyway.
What Is a MET Value?
Each activity in the calculator has a MET value, short for metabolic equivalent. One MET is the energy you use sitting still, and an activity rated at 4 METs uses about four times that. Brisk walking is around 4.3 METs, moderate cycling about 6.8 and running at 8 km/h about 8.3. The values are averages from exercise-science research, so they suit most healthy adults but not every person or every workout.
How Calories Burned Are Calculated
The formula is simple: multiply the MET value by your weight in kilograms and by the time in hours. Pounds are converted to kilograms first.
Because the result depends on body weight, a heavier person burns more calories for the same activity and time. That is why the same 30-minute run is about 249 calories at 60 kg but 332 calories at 80 kg.
Calories Burned in 30 Minutes by Activity
This table shows the estimated calories for six common activities at four body weights. Use it as a quick comparison, or enter your own numbers in the calculator for a personal result.
| Activity (30 minutes) | MET | 60 kg | 70 kg | 80 kg | 90 kg |
|---|---|---|---|---|---|
| Walking, brisk (5.6 km/h, 3.5 mph) | 4.3 | 129 | 151 | 172 | 194 |
| Cycling, moderate (16 to 19 km/h) | 6.8 | 204 | 238 | 272 | 306 |
| Running, 8 km/h (5 mph) | 8.3 | 249 | 291 | 332 | 374 |
| Swimming laps, light to moderate | 5.8 | 174 | 203 | 232 | 261 |
| Weight training, vigorous | 6 | 180 | 210 | 240 | 270 |
| Yoga, hatha | 2.5 | 75 | 88 | 100 | 113 |
Using Your Results
The numbers help you compare workouts and plan sessions, for example choosing between a long walk and a shorter, harder run. To see your daily calorie needs, try the calorie calculator, and the BMR calculator shows what your body uses at rest. If you run, the running calculator turns distance and time into pace and race predictions. Long sessions also call for fluids, and the water intake calculator can help you plan.
Limits of Calorie Estimates
MET-based estimates are averages. Fitness level, body composition, age, terrain, temperature, wind and effort all change the real figure, and wearable devices often show different numbers for the same workout. Treat the result as a reasonable guide rather than an exact measurement, and talk to a doctor or qualified trainer before starting an intense exercise program, especially if you have a health condition.
Who Can Use This Calculator?
Anyone tracking workouts or daily activity, people working on weight goals, runners, cyclists and swimmers, gym users comparing exercises, fitness coaches and personal trainers, and anyone curious about how much energy walking, housework or sport really uses.
