Estimate treadmill calories from your weight, session duration and an activity category. This calculator uses a fixed intensity estimate; it does not accept your exact belt speed or incline.
Use the treadmill setting
Select “Treadmill, brisk or incline”, enter kilograms and active minutes, and leave steps at zero. That category uses 5.5 MET. Record belt speed and incline separately if you want to compare sessions.
Worked example: 75 kg for 30 minutes
The calculation is 5.5 × 3.5 × 75 ÷ 200 × 30 = about 217 kcal. This is estimated total energy during that half hour, including resting energy. Subtracting a conventional 1 MET resting allowance gives about 177 active kcal; watches may report that different measure.
Why your machine may disagree
One fixed category cannot represent both gentle flat walking and a steep climb. Holding your weight on the handrails also changes the effort. Compare duration, speed, incline and perceived effort before comparing calorie totals. For a speed-specific estimate, consult the Compendium activity table rather than treating 5.5 MET as a measured value.
Compendium of Physical Activities: METs
Estimate: kcal/min = MET × 3.5 × kg ÷ 200. When steps are entered and duration is blank, this tool assumes 100 steps per minute. MET values are population averages. Incline, terrain, wind, fitness, technique, handrail use and individual physiology change actual energy use. Not medical or nutrition advice.
Schatting: MET × 3,5 × kg ÷ 200. MET-waarden zijn gemiddelden en geen directe meting of medisch advies.
