Enter your weight, choose your stair activity (slow climb, fast climb, descending, and more), and set your duration to see how many calories you burn on stairs. Results are based on the MET (Metabolic Equivalent of Task) formula used by exercise scientists.

MET stands for Metabolic Equivalent of Task — a measure of how much energy an activity requires relative to rest. A MET of 1 means you're burning roughly 1 kcal per kg of body weight per hour at rest. Stair climbing has a MET between 3.5 and 8.8 depending on speed and load, meaning it burns significantly more calories than sitting still. Using MET makes calorie estimates more accurate across different body weights.
The formula is: Calories = (MET × body weight in kg × 3.5 × duration in minutes) / 200. This is the standard exercise science formula used in research and fitness tools. MET values vary by activity — slow stair climbing uses a MET of about 4.0, while fast stair climbing can reach 8.8.
A 170 lb (77 kg) person climbing stairs at a slow pace for 30 minutes burns approximately 325–400 calories. At a fast pace, that can rise to 700–800 calories for the same duration. The exact number depends on your weight and the intensity of the activity.
Yes — stair climbing is a highly effective calorie-burning exercise that engages large muscle groups including glutes, quads, hamstrings, and calves. Because it's weight-bearing, it also supports bone density. Consistently replacing elevator rides with stair climbing can contribute meaningfully to a calorie deficit over time.
Stair climbing primarily works the quadriceps, hamstrings, glutes, and calves. The core muscles also engage for stability, especially when climbing quickly or carrying a load. Going upstairs places more emphasis on the glutes and quads, while descending engages the quads and knees more heavily.
For most healthy adults, moderate stair climbing every day is safe and beneficial. However, if you're new to exercise or have knee or joint issues, starting with shorter sessions and gradually increasing intensity is advisable. Listen to your body and rest if you experience pain or excessive fatigue.
Experts generally recommend at least 150 minutes of moderate-intensity aerobic activity per week for weight management. Stair climbing qualifies as moderate-to-vigorous activity, so 20–30 minutes per session, 5 days a week, can be an effective routine. Pairing it with a balanced diet will produce the best results.
Yes — carrying a load significantly increases calorie burn because your muscles must work harder to move the additional weight. The heavier the load, the higher the MET value and the more calories you burn per minute. Carrying more than 34 kg upstairs can have a MET above 8, rivaling intense running.
