What This Calories Burned Calculator Estimates

This tool estimates session calorie burn from three inputs: activity MET value, body weight, and duration. It reports both total calories and active calories above resting metabolism.

Formula Used

Calculations follow standard MET energy equations:

Total kcal = MET x body weight (kg) x duration (hours)

Active kcal = (MET - 1) x body weight (kg) x duration (hours)

MET values are representative activity benchmarks and can vary with pace, technique, terrain, and fitness level.

How To Use This for Planning

Use this as your movement-expenditure layer, then align intake targets with your actual training week. For maintenance setup, run the TDEE Calculator. For intake targeting, use the Calorie Deficit Calculator and convert calories into macros in the Macro Calculator.

If your primary movement target is step count, compare this with the Steps to Calories Calculator.
