Calories Burned Calculator
Estimate how many calories you burn during walking, running, cycling, swimming or weight training based on your body weight and workout duration.
About Calories Burned Calculator
The calories burned calculator estimates the energy you use during five common workouts — walking, running, cycling, swimming and weight training — from your body weight and how long you exercise. Weight matters because moving a heavier body costs more energy per minute.
It uses the standard MET formula: kcal = MET × 3.5 × weight in kg ÷ 200 × minutes. Each activity has a typical MET (metabolic equivalent) value — 3.5 for walking, 9.8 for running, 7.5 for cycling, 8.0 for swimming and 5.0 for weight training — shown with your result along with the burn per minute and per hour.
Use it to compare workouts, plan a calorie deficit or fill gaps when you train without a fitness tracker. It is free, works in metric or imperial units, and runs entirely in your browser.
