What this calculator does
The Calories Burned Climbing Stairs Calculator estimates how much energy you expend walking or running up stairs. It uses the standard MET (Metabolic Equivalent of Task) method, which links the intensity of an activity, your body weight, and the time spent to total calories burned. Stair climbing is a vigorous, high-impact cardio activity, so it burns calories quickly compared with flat walking.
How to use it
Enter your body weight in kilograms, the number of minutes you spent climbing, and choose an intensity level. The MET value represents how hard the activity is: a slow, leisurely climb is about 4.0, general stair climbing is about 8.0, and running quickly up stairs can reach 15.0. The tool returns your total calories burned plus a per-minute breakdown.
The formula explained
The calculation is $$\text{kcal} = \frac{\text{MET} \times 3.5 \times \text{kg}}{200} \times \text{minutes}$$. The constant 3.5 ml/kg/min is resting oxygen consumption (one MET). Multiplying by your weight and the MET value, then dividing by 200, converts oxygen use into calories per minute. Multiplying by your total minutes gives the calories burned for the whole session.
Worked example
Suppose a 70 kg person climbs stairs at a general pace (MET 8) for 10 minutes. Per minute: $$8 \times 3.5 \times 70 \div 200 = 9.8 \text{ kcal/min}.$$ Over 10 minutes that's \(9.8 \times 10 = \)98 kcal.
FAQ
Is this accurate? MET-based estimates are good general approximations but don't account for fitness, body composition, or stair steepness, so treat results as a guide.
What MET should I pick? Use 4.0 for a relaxed climb, 8.0 for normal steady climbing, and 15.0 for fast or running ascents.
Does this work for a stair machine? Yes — choose the intensity that matches your effort; a hard stepper session is roughly MET 8–9.
