Calorie Burn Calculator

Estimate calories burned during exercise using MET values.

Calorie burn estimates are approximate and do not replace medical or fitness advice.

Activity-based estimateMetric & imperial supportReviewed for accuracy

Calorie burn calculator

Choose an activity, enter your weight and duration, and estimate calories burned.

Unit system
Calories burned depends strongly on body weight, duration, and intensity.
Activity estimates use typical MET values.
Actual energy use varies by fitness level, technique, terrain, and physiology.

Estimated calories burned

kcal

Based on Running (6 mph), 30 minutes, 70 kg, and a MET value of 9.8.

Calories per minute

12.0 kcal/min

Hourly burn estimate

720 kcal/hr

Intensity / MET

Vigorous · 9.8 MET

Uses standard activity-based calorie estimation. Reviewed for accuracy. Estimate only. Does not replace medical, dietetic, or professional fitness advice.

Personalized interpretation

Based on your inputs, this activity may burn about 360 calories.

That equals roughly 12.0 calories per minute over 30 minutes.

Higher intensity or longer duration increases estimated calorie burn. Actual burn may vary based on fitness level, movement efficiency, terrain, heart rate, and individual physiology.

Do not rely on exercise calories alone for medical or weight-management decisions.

How calorie burn is estimated

Calorie burn estimates energy used during activity.
Body weight is a major input.
Duration increases total calories.
MET values estimate activity intensity.

MET values and activity intensity

MET stands for Metabolic Equivalent of Task. One MET is roughly resting energy use. Higher MET activities generally burn more energy per minute.

Walking

3–5 METs

Light to moderate depending on speed.

Running

8–14 METs

Varies strongly by pace and terrain.

Cycling

4–12 METs

Depends on speed, hills, and resistance.

Swimming

6–10 METs

Technique and effort change burn.

Strength training

3–6 METs

Varies by rest time and load.

Housework

2–4 METs

Usually light to moderate activity.

Exercise duration, body weight, and intensity

Longer duration increases total estimated calories burned.

Higher body weight generally increases estimated burn for the same activity.

Higher intensity increases estimated burn per minute.

Technique, terrain, and fitness level can affect actual output.

Calories burned vs fat loss

Calories burned during exercise are only one part of energy balance. Food intake, resting metabolism, daily activity, sleep, and consistency also matter.

Exercise has benefits beyond calorie burn, including strength, cardiovascular fitness, mood, mobility, and long-term health.

Accuracy limits and tracking context

Calorie burn estimates are best used for comparison and planning. Trends are more useful than single numbers.

Formula explanation

Calories Burned = MET × Body Weight in kg × Duration in hours
Calories Burned = MET × 3.5 × Body Weight in kg ÷ 200 × Duration in minutes

MET represents activity intensity, body weight is converted to kilograms, and duration is the exercise time. Estimates vary because real-world movement, efficiency, and physiology vary.

Example: 70 kg cycling

8 × 3.5 × 70 ÷ 200 × 30 ≈ 294 calories.

Example: 180 lb brisk walking

At 4.3 MET for 45 minutes, estimated burn is about 276 calories.
