Calorie Burn Calculator
Calories are burned when your body uses energy for movement and metabolism. This calculator estimates how many calories you burn during a specific activity using MET values: enter your weight, choose an activity type, and duration. You get total kcal, kJ, calories per hour, and an optional fat-loss equivalent. Results are hidden until you run the calculation.
What Is the Calorie Burn Calculator?
The calorie burn calculator estimates how many calories you burn during a specific activity based on your weight, the type of exercise, and duration. It uses MET (metabolic equivalent of task) values — a standard way to compare energy cost of different activities. You get total kcal, kJ, calories per hour, and an optional fat-loss equivalent. No sign-up or external data required.
How Does the Calorie Burn Calculator Work?
You enter your weight (metric or imperial), choose an activity from the list (e.g. walking, running, cycling, strength training), and duration in minutes. The calculator converts weight to kg and applies the formula: calories = MET × weight (kg) × duration (hours). Each activity has a fixed MET value; duration is converted from minutes to hours for the calculation.
Why Use This Calorie Burn Calculator?
Knowing how many calories you burn per workout helps you plan intake, create a deficit, or fuel properly. This calorie burn calculator gives you a clear number for each session and per hour so you can compare activities. Use it with our TDEE calculator and calorie deficit calculator to see how exercise fits your daily budget.
Who Should Use This Tool?
Anyone who wants to estimate calories burned by activity can use this calorie burn calculator — from casual exercisers to regular gym-goers. It is useful for weight loss planning (how much to eat vs. burn), comparing exercises, and understanding hourly burn rates. Pair it with our calorie calculator and protein calculator for full nutrition and training planning.
How Are Calories Burned?
Your body burns calories all day for basic functions (breathing, circulation, digestion) and for activity. The more intense and longer the activity, the more energy you use. Exercise calorie burn depends on your body weight, the type and intensity of the activity, and duration. This calculator uses MET (metabolic equivalent of task) values to estimate energy expenditure. To see your total daily burn, use our TDEE calculator; for a daily calorie target, try our calorie calculator.
What Is a MET Value?
MET stands for metabolic equivalent of task. One MET is the energy cost of sitting at rest. An activity with 4 METs uses about four times that energy. MET values are standardized so you can compare activities: for example, brisk walking is around 4 METs and running is 8–11 METs depending on speed. The formula used here is: calories burned = MET × weight (kg) × duration (hours). So heavier people burn more calories for the same activity and time, and higher MET activities burn more per minute.
Calories Burned by Activity
Different activities have different MET values. Light walking is around 2.5 METs, brisk walking 4, moderate running 8, fast running 11, cycling about 7.5, strength training 6, swimming 8, and HIIT around 9. The calculator includes these and shows calories burned for your weight and duration. You also see calories per 30 minutes and per hour so you can plan workouts. Combine with our calorie deficit calculator to see how exercise contributes to weight loss.
How Accurate Is This Calculator?
MET-based estimates are reasonable for most people but can vary with fitness, form, and environment. They are best for comparing activities and planning rather than an exact count. Actual burn can be 10–20% higher or lower. Use the result as a guide and track progress over time. For overall daily energy needs, the TDEE calculator and body fat calculator help you understand composition and total expenditure.
How Exercise Helps Weight Loss
Exercise increases the calories you burn and can create or enlarge a calorie deficit when combined with diet. It also helps preserve muscle and improve health. The calculator’s “fat loss equivalent” (calories ÷ 7700) is a rough guide: 1 kg of body fat is about 7700 kcal, so burning 7700 kcal through exercise could theoretically match 1 kg fat loss if diet stays the same. In practice, weight change depends on total intake and expenditure. Use our calorie calculator and protein calculator to set intake and protect muscle while losing fat.
Best Exercises for Burning Calories
Higher MET activities burn more calories per minute: running, HIIT, swimming, and cycling are among the highest. The best exercise for you is one you can do consistently and enjoy. Mix cardio and strength training — strength training builds muscle and can raise resting metabolism. Use this calorie burn calculator to compare activities and see how duration affects total burn, then pair with your macro calculator and calorie deficit calculator for a full plan.
