Calories Burned Calculator
Estimate the calories burned by an activity from its intensity, your weight and the duration.
Energy used by exercise
Different activities burn energy at different rates, and heavier bodies burn more for the same activity. This estimates the calories burned from the activity, your weight and how long you did it, giving a sense of the energy cost of exercise.
Choose an activity, enter your weight and time, to estimate calories burned.
Why these are rough estimates
Calorie-burn figures are approximate, and often less than people expect or than fitness trackers claim. The estimate is based on typical energy costs for an activity scaled by body weight, but real burn depends on your fitness, intensity, efficiency and individual metabolism, so two people doing the same workout can burn quite different amounts. It is a useful ballpark for comparing activities and getting a rough sense of energy used, not a precise figure to base eating on. This is general information, not nutrition or medical advice; exercise for health and enjoyment rather than treating calorie numbers as exact, and consult a professional for guidance suited to you.
Calories Burned Calculator FAQ
How accurate are calories-burned estimates?
Approximate — they scale a typical energy cost by body weight, but real burn depends on fitness, intensity and metabolism, so individuals vary.
Why is the estimate lower than my tracker's?
Fitness trackers often overestimate. Any estimate is a ballpark, best used to compare activities rather than as a precise figure to eat back.
Is this nutrition advice?
No — it is general information. Exercise for health and enjoyment rather than treating calorie numbers as exact, and consult a professional if needed.
