This calories burned calculator estimates how much energy a specific workout or activity costs you, based on your body weight, the activity you choose, and how long you do it. Instead of guessing at a round number after a walk or a gym session, you enter your details once and get a per-session estimate, an hourly rate, and a weekly total if you repeat the activity regularly.
How to use this calories burned calculator
- Under “Your activity,” choose your unit system by toggling between Metric (kg) and Imperial (lb).
- Enter your weight in the “Your weight (kg)” field (or the pound equivalent if you switched units).
- Open the activity dropdown and pick your exercise. Activities are grouped into Walking & Running, Cycling, Gym & Training, Sports, and Everyday, or you can select Custom to enter your own MET value.
- Enter the length of your session in the “Duration (minutes)” field.
- Enter “Sessions per week” if you want a weekly total in addition to the single-session result.
- Select “Calculate calories burned” to generate the results.
- Review the output: calories burned per session, per-minute and hourly burn rates, weekly total, body fat equivalent, MET intensity value, steps equivalent, and food equivalents.
- Use “PDF report,” “Share,” or “Copy report” if you want to save or send the result.
What this calories burned calculator does
This tool is built specifically for activity-based energy expenditure, not for estimating your total daily calorie needs or setting a diet target. It answers one question: for this activity, at this duration, and at your body weight, how many calories did you likely burn? Each activity in the dropdown carries a MET value, a standardized measure of how intense that activity is relative to sitting still. Walking casually sits at 3.5 MET, brisk walking at 4.3 MET, hiking at 6.0 MET, and running ranges from 8.3 to 11.5 MET depending on speed. Cycling ranges from 4.0 MET at a leisure pace up to 10.0 MET for vigorous riding, with a stationary bike option at 6.8 MET. Gym and training activities span weightlifting (3.5 to 6.0 MET), HIIT (8.0 MET), elliptical (5.0 MET), rowing (7.0 MET), jump rope (11.0 MET), aerobics (7.3 MET), yoga (2.5 MET), and pilates (3.0 MET). Sports options include swimming (5.8 to 9.8 MET), basketball (6.5 MET), football or soccer (7.0 MET), tennis (7.3 MET), badminton (5.5 MET), cricket (4.8 MET), and dancing (5.5 MET). Everyday activities like stair climbing (4.0 to 8.8 MET), housework (3.3 MET), and gardening (3.8 MET) are also included, so the calculator covers more than structured workouts.
The MET-based formula behind the numbers
Every result from this calories burned calculator comes from the standard MET formula, which multiplies activity intensity by body mass and time spent.
Calories = MET x Weight (kg) x Duration (hours)
A heavier body burns more for the same activity because it takes more energy to move more mass. A longer duration scales the result linearly, so doubling your time roughly doubles your calorie estimate at a steady pace. Intensity is where the activity choice matters most: brisk walking at 4.3 MET burns noticeably less than running at 8 km/h (around 8.3 MET), even over the same 30 minutes and at the same body weight. The page itself gives worked examples at 70 kg: 30 minutes of brisk walking comes out to roughly 158 kcal, 30 minutes of running at 8 km/h comes out to roughly 305 kcal, and 30 minutes of swimming comes out to roughly 213 kcal. These examples show how much the activity selection changes the outcome even when weight and duration are held constant.

If your activity is not listed, the Custom option lets you enter a MET value from another reference source and still get a session and weekly estimate from this calories burned calculator.
Why weekly totals and other outputs matter
Entering “Sessions per week” extends a single-session estimate into a weekly total, useful if you repeat the same workout on a schedule. The additional outputs, steps equivalent, body fat equivalent, and food equivalents, translate the raw kcal figure into more relatable terms so you can see roughly how a session compares to a known quantity of food or movement.
A note on accuracy
MET values represent population averages, so the numbers from this calories burned calculator will not match everyone exactly. Actual burn depends on fitness level, exercise technique, terrain, and effort, and wearable fitness trackers can differ from lab measurements by 20 percent or more in either direction. Treat the results as a reasonable estimate for planning and tracking trends over time, not as an exact physiological measurement. This calculator is for general fitness information only and is not medical advice; consult a healthcare professional for guidance specific to your health.
Frequently asked questions
How accurate is this calories burned calculator?
It is accurate to the extent that MET values are accurate for the general population. Since MET values are averages, individual results vary with fitness level, technique, and terrain, and can differ from what a fitness tracker reports by 20 percent or more.
Do I need to know my activity’s MET value?
No. The dropdown already assigns a MET value to each listed activity across Walking & Running, Cycling, Gym & Training, Sports, and Everyday categories. You only need to know your weight and how long you did the activity. If your activity is not listed, use the Custom option to enter your own MET value.
What is the difference between this and a calorie deficit or surplus calculator?
This calories burned calculator is limited to estimating energy expended during a specific exercise or activity session, based on MET value, weight, and duration. It does not calculate your total daily calorie needs or a target for weight loss or weight gain, which is what a calorie deficit or surplus calculator is built for.
Does the calculator account for intensity within an activity?
Yes, several activities list multiple entries for different intensity levels, such as casual versus brisk walking, or leisure versus vigorous cycling. Selecting the option that matches your actual effort level gives a more useful result from this calories burned calculator.
