About this tool
Step-mill calorie burn from steps per minute, step height and body weight, using the mechanical work of climbing and a 25% efficiency factor.
The Stairmaster Calorie Calculator estimates step-mill energy expenditure from the mechanical work of lifting your body mass — body weight times gravity times climbing speed — divided by the roughly 25 percent gross efficiency of stair climbing, with resting metabolism added back on. Because climbing is almost pure vertical work, that approach responds properly to step rate, step height and handrail use instead of applying one flat MET value to every session. At 70 steps per minute on a standard 8-inch step it reproduces the 9.0 MET figure the Compendium of Physical Activities lists for a stair-treadmill ergometer.

Enter the values you already know.
Fine-tune the options to match your scenario.
Read the result and use it in your planning or reporting.
Uses work done against gravity, so doubling the step rate genuinely doubles the climbing component.
Separates the exercise cost from the resting calories you would have burned anyway.
Applies a documented reduction when you rest or lean on the rails, which consoles ignore.
About 315 kcal for a 70 kg person at 70 steps per minute, of which roughly 280 kcal is above resting metabolism. Body weight drives the result almost linearly, so a 90 kg person at the same settings burns about 405 kcal.
Yes, substantially. Resting your hands on the rails cuts the work by roughly 8 percent, and leaning your weight through them by about 20 percent, because part of your body mass is no longer being lifted by your legs. The machine's own console cannot detect this, which is one reason its calorie figure usually reads high.
At matched effort they are similar, but the step mill reaches a high MET value at a pace most people can sustain — 9 METs at 70 steps per minute — without the joint impact of running. The best choice is the one you will actually do for the full session.
Gym consoles typically report gross calories, often assume a default body weight if you did not enter one, and cannot account for handrail support or your individual efficiency. Treat any calorie readout, including this one, as an estimate with a margin of roughly 10 to 20 percent.
