Based on the Metabolic Equivalent of Task (MET) formula.


Understanding Walking Calorie Burn

Walking is one of the most accessible forms of cardiovascular exercise. Whether you are strolling through a park or power walking to a meeting, your body is burning energy. This Walking Calories Calculator helps you estimate the energy expenditure of your walking sessions based on three primary factors: your body mass, the duration of the walk, and the intensity (speed).

How the Calculation Works

This calculator uses the MET (Metabolic Equivalent of Task) method. MET is a ratio that compares your active metabolic rate to your resting metabolic rate. One MET is defined as the energy cost of sitting quietly. As you increase your walking speed, your MET value increases:

  • 2.0 METs: Slow walking on a firm surface.
  • 3.5 METs: Walking at a moderate, steady pace.
  • 4.3 METs: Brisk walking.
  • 5.0 METs: Very brisk walking.

The Formula

Calories = (MET × 3.5 × Weight in kg / 200) × Duration in minutes

Examples of Walking Calorie Burn

Weight Pace Time Burn
150 lbs (68 kg) 3.0 mph 30 mins 125 kcal
200 lbs (91 kg) 3.5 mph 60 mins 410 kcal
180 lbs (82 kg) 4.0 mph 45 mins 310 kcal

Factors Influencing Your Results

While this tool provides a highly accurate estimate, individual results may vary based on:

  • Incline: Walking uphill significantly increases calorie burn compared to flat ground.
  • Surface: Walking on sand or uneven terrain requires more effort than pavement.
  • Age and Muscle Mass: People with higher muscle mass often burn more calories at rest and during activity.
  • Efficiency: As you become a more experienced walker, your body may become more efficient, slightly lowering the burn.
