How Treadmill Calories Are Calculated

Most treadmill displays overestimate your calorie burn by 15-20%. This calculator uses the MET (Metabolic Equivalent of Task) formula, which is the gold standard in exercise science.

The Formula

The math behind the calculation is: Calories = MET × Weight (kg) × Time (hours).

We automatically adjust the MET value based on your speed and incline:

  • Walking (3 mph): Approx 3.5 METs
  • Jogging (5 mph): Approx 8.0 METs
  • Running (8 mph): Approx 11.5 METs

Why Use This Tool?

Accuracy matters for weight loss. If you overestimate your burn, you might overeat later. This tool provides a conservative, realistic estimate to help you stay in a calorie deficit.
