Understanding how many calories you burn while working can be incredibly useful for managing weight, planning meals, and maintaining overall health. Whether you sit at a desk or perform physically demanding labor, your daily activities consume energy. The Calories Burned at Work Calculator is a free online tool designed to help you estimate exactly how many calories you burn during your work hours — daily, weekly, and monthly.

This calculator is ideal for employees, fitness enthusiasts, health coaches, and anyone curious about their energy expenditure throughout the workday. It’s fast, easy to use, and provides personalized results in seconds.

How the Calories Burned at Work Calculator Works

The calculator estimates the calories burned based on your body weight, work duration, activity level, and number of workdays per week. It uses the Metabolic Equivalent of Task (MET) formula — a standardized method in exercise science to measure energy expenditure for various activity levels.

By selecting your job’s activity intensity, entering your weight and working hours, the tool calculates your total calorie burn per day, week, and month. The results appear after a short progress animation, making it both informative and interactive.

Example Calculation

Let’s say you weigh 70 kg, work 8 hours a day, have a desk job (activity level 1.3), and work 5 days per week.

• Calories per minute: (1.3 × 3.5 × 70) / 200 = 1.6 kcal/min
• Calories per day: 1.6 × (8 × 60) = 768 kcal
• Calories per week: 768 × 5 = 3,840 kcal
• Calories per month: 3,840 × 4 = 15,360 kcal

So, in this example, you burn approximately 768 calories per workday and over 15,000 calories per month just from your job!
