How to Calculate Calories Burned on a StairMaster

The StairMaster burns roughly 8 to 12 calories per minute for most people at a moderate-to-vigorous pace, which is about 250 to 300 calories in 30 minutes or 500 to 700 in an hour. Your exact number depends on your body weight, the level you set, and how long you climb. Use the formula and charts below to calculate StairMaster calories burned for any time, weight, or intensity.

Quick Answer

For a 155-pound person at a moderate pace, the StairMaster burns about 98 calories in 10 minutes, 148 in 15 minutes, 295 in 30 minutes, and 590 in an hour. Heavier bodies and higher levels burn more, lighter bodies and easier levels burn less. Every figure on this page is an estimate within about 15 to 20 percent, since no machine or formula measures your burn exactly.

How to Calculate StairMaster Calories Burned

Calories burned on a StairMaster are calculated with MET values, where a MET measures how much energy an activity uses compared to sitting still. The formula gives calories per minute:

Calories per minute = (MET x body weight in kg x 3.5) / 200

The StairMaster's MET value depends on effort. The 2024 Adult Compendium of Physical Activities rates a stair-treadmill ergometer at about 9 METs, a vigorous intensity for most adults. Use this scale:

• Light effort (low levels): 6 to 7 METs
• Moderate effort (mid levels): 7 to 8 METs
• Vigorous effort (high levels): 9 to 11 METs

Worked example. A 155-pound person (70 kg) at a moderate pace (8 METs) burns (8 x 70 x 3.5) / 200 = about 9.8 calories per minute, or roughly 295 calories in 30 minutes.

StairMaster Calories Burned by Time and Weight

The chart below estimates calories burned at a moderate-to-vigorous pace (about 8 METs). Find your weight across the top and your time down the side. Lighter effort burns roughly 20 percent less; higher levels burn more.

To estimate a time not listed, multiply the per-minute rate for your weight (about 7.9 calories at 125 lbs, 9.8 at 155 lbs, 11.8 at 185 lbs) by your minutes.

StairMaster Calories Burned by Level

Higher StairMaster levels burn more calories because they raise your steps per minute, which raises intensity. The level sets your pace, and pace drives the burn. As a rough guide against the moderate baseline in the chart above:

• Low levels (about 1 to 5): light effort, roughly 15 to 20 percent fewer calories than the chart.
• Mid levels (about 6 to 12): moderate to vigorous, close to the chart figures.
• High levels (about 13 to 20): vigorous, roughly 20 to 40 percent more than the chart.

So a 155-pound person at level 7 for 10 minutes burns roughly 90 to 110 calories, while the same person at level 15 for 10 minutes may burn 120 to 140. The machine's own calorie readout uses your level and weight, but it tends to run high, so treat it as a ceiling rather than a precise count.

Steps, Floors, and Calories

On most StairMaster machines, about 10 steps equals 1 floor, so 100 floors is roughly 1,000 steps. How many calories that burns depends on your pace, not the floor count alone. At a typical 65 to 80 steps per minute, climbing 100 floors takes most people about 13 to 20 minutes and burns roughly 130 to 250 calories, scaling with body weight. For a quick per-step estimate, an average adult burns about 0.10 to 0.15 calories per step climbed.

StairMaster vs Other Cardio (30 Minutes, 155 lbs)

Running usually burns slightly more per minute, but the StairMaster delivers strong cardio with less joint impact and more glute and quad engagement.

Burning More Across the Whole Day

A StairMaster session burns real calories, but it is a small slice of your day, and for anyone who sits at a desk for hours the rest of the day matters just as much. Most of the difference in daily burn between active and sedentary people comes from everyday movement, not workouts. Standing and moving during the workday adds to it modestly: a Mayo Clinic meta-analysis found standing burns about 0.15 calories more per minute than sitting, roughly 54 extra calories over a six-hour day. It will not replace a StairMaster workout, but a standing desk that makes it easy to break up sitting, or simple active sitting habits, keeps that movement going after you step off the machine.

Frequently Asked Questions

How many calories does the StairMaster burn?

The StairMaster burns about 8 to 12 calories per minute for most people at a moderate-to-vigorous pace. That is roughly 250 to 300 calories in 30 minutes and 500 to 700 in an hour for a 155-pound person. Body weight and level move the number up or down.

How many calories does 10 minutes on the StairMaster burn?

Ten minutes on the StairMaster burns about 80 to 120 calories at a moderate pace, or roughly 98 for a 155-pound person. Heavier bodies and higher levels burn toward the top of that range, lighter bodies toward the bottom.

How many calories does 15 minutes on the StairMaster burn?

Fifteen minutes on the StairMaster burns about 120 to 175 calories at a moderate pace, around 148 for a 155-pound person. Raising the level increases the burn by roughly 20 to 40 percent.

How many calories does 20 minutes on the StairMaster burn?

Twenty minutes on the StairMaster burns about 160 to 235 calories at a moderate pace, roughly 197 for a 155-pound person. Add more at higher levels or greater body weight.

How many calories does 30 minutes on the StairMaster burn?

Thirty minutes on the StairMaster burns about 250 to 300 calories at a moderate pace for a 155-pound person, more for heavier bodies or higher levels. Treat it as an estimate within 15 to 20 percent.

How many calories does an hour on the StairMaster burn?

An hour on the StairMaster burns roughly 500 to 700 calories at a moderate pace for a 155-pound person, and 800 or more for heavier users at high levels. Few people sustain an hour, so most sessions land well under this.

How many calories does 100 floors on the StairMaster burn?

Climbing 100 floors, about 1,000 steps, burns roughly 130 to 250 calories depending on your weight and pace. It usually takes 13 to 20 minutes, and the calorie total tracks the time and effort more than the floor count itself.

Does the StairMaster burn belly fat?

The StairMaster helps reduce overall body fat but cannot target belly fat specifically. Spot reduction is a myth; fat loss happens across the whole body and depends on your total calorie balance over time, not on one machine.

Is the StairMaster calorie readout accurate?

The StairMaster's on-screen calorie count is a rough estimate and usually runs high, because it does not know your exact body composition. Entering your correct weight helps, but treat the number as a ceiling and expect your real burn to be somewhat lower.

Final Thoughts

Calculating StairMaster calories burned comes down to one formula, your body weight, and how hard you climb. The charts above give a realistic estimate for any time and level, and the FAQ answers the most common time-based questions directly. Enter your real weight, treat the machine's readout as a high estimate, and remember that a single session is one part of your daily movement rather than the whole picture.
