Calories Burned Calculator for Any Activity
This calories burned calculator estimates how many calories you burn during exercise or everyday activity. Enter your weight, pick an activity, and set the duration to see your calorie burn instantly. It works for 60+ activities across cardio, cycling, swimming, strength, sports, and more.
Each estimate uses the MET (Metabolic Equivalent of Task) values from the 2024 Compendium of Physical Activities, applied with the formula Calories = MET × Weight (kg) × Duration (hours). You can also stack several activities into one workout session and watch the running total, making it handy for tracking a full gym visit or a mixed-cardio day.
How to Calculate Calories Burned
Enter your weight
Type your body weight in the Weight field. Use the kg / lbs toggle to switch units — your weight and unit are saved automatically for your next visit.
Select an activity
Open the Activity dropdown to browse 60+ exercises grouped into 8 categories, or use the search box to find one fast by typing its name.
Set the duration
Enter how long you did the activity in minutes, or tap a quick preset — 15, 30, 45, or 60 minutes.
Read your results
See total calories burned, the activity's MET value, its intensity level, the calories-per-minute rate, and how the burn compares to common foods — all updating in real time.
Build a session (optional)
Tap Add to Session to log the activity, then add more to see total calories across the whole workout. Remove single entries or clear the session anytime.

Frequently Asked Questions
How are calories burned calculated?
The calculator uses the MET formula: Calories = MET × Weight (kg) × Duration (hours). Each activity has a MET value — the energy cost relative to rest — so multiplying it by your weight and how long you exercised gives an estimate of the calories you burned.
How many calories does walking, running, or cycling burn?
It depends on your weight and pace. Moderate walking has a MET of about 3.3, running at 6 mph is around 9.8, and moderate cycling is roughly 6.8. Select the specific pace from the activity list and set your duration, and the calculator returns the exact estimate for you.
Does body weight affect calories burned?
Yes. Calorie burn is directly proportional to body weight. A heavier person expends more energy doing the same activity at the same intensity, because it takes more energy to move a larger body mass. That is why the calculator asks for your weight.
How accurate is this calories burned calculator?
Estimates are based on MET values from the 2024 Compendium of Physical Activities and are generally accurate within about ±15–20%. Real-world burn varies with fitness level, body composition, age, and environmental conditions, so treat the result as a close estimate rather than an exact measurement.
Can I track multiple activities in one session?
Yes. After each calculation, tap Add to Session to build a multi-activity workout log. The session shows every activity with its duration, MET value, and calories, plus a running total. You can remove a single entry or clear the whole session.
Why isn't my exact activity in the list?
The calculator covers 60+ of the most common activities. If yours isn't listed, pick the closest match by similar intensity and movement pattern. The search box helps you spot related options quickly.
Is my data stored or shared?
No. All calculations happen entirely in your browser. Only your weight and unit preference are saved to your browser's local storage for convenience — no data is sent to any server.
