Calories Burned Climbing stairs at 85 kg — 748 kcal per Hour
Climbing stairs at 85 kg (176-198 lb) burns about 748 kcal per hour. That figure comes from the activity's MET value of 8.8 in the 2011 Compendium of Physical Activities, multiplied by body weight: 8.8 x 85 kg x 1 hour = 748 kcal. This page works the numbers out in full - for 15, 30, 45, 60 and 90 minutes, across all four weight bands, and against four comparable activities at the same weight - so you can plan sessions with real figures instead of guessing.
Climbing stairs at a fast pace is one of the most intense activities you can do without any equipment: 8.8 METs puts it above most running speeds. Every step lifts your whole body weight against gravity, and there is no coasting — the effort is continuous from the first step to the last.
Stair climbing suits time-poor exercisers — a stairwell is everywhere — and it builds leg strength and stamina fast. It is demanding, so beginners should start with short bouts. The headline number to remember is 748 kcal per hour at 85 kg, or about 374 kcal for a 30-minute session. Everything below is an estimate: MET values are population averages, and your own burn will vary with fitness, technique and conditions. That does not make the numbers useless — it makes them a planning tool, and a good one, as long as you treat them as approximate.
Calculate your own numbers
Use the calorie calculator to work out your own burn for climbing stairs at your exact weight and session length. Enter your weight, pick the activity and set the duration, and the tool applies the same MET formula shown below. You can also try the calorie calculator to see how this session fits into your total daily energy use.

The formula, shown and cited
The standard way to estimate the energy cost of an activity is the MET formula from the Compendium of Physical Activities (Ainsworth et al., Medicine & Science in Sports & Exercise, 2011; 43(8): 1575-1581):
Calories (kcal) = MET x body weight (kg) x duration (hours)
One MET is the energy you use sitting quietly at rest - about 1 kcal per kilogram of body weight per hour. An activity rated at 8.8 METs therefore uses 8.8 times as much energy as resting. The Compendium's MET values come from published studies that measured oxygen use during each activity, so they are measured averages, not guesses. The data file records this as stair climbing at a fast pace (8.8).
Worked through for this page:
- MET for climbing stairs: 8.8
- Body weight: 85 kg (the midpoint of the 80-90 kg band, 176-198 lb)
- Duration: 1 hour
- Calculation: 8.8 x 85 x 1 = 748 kcal
For a 30-minute session the same calculation is 8.8 x 85 x 0.5 = 374 kcal. Nothing else is hidden in the maths - if your weight or duration changes, only those two numbers change.
Your numbers at 85 kg
| Duration | Calculation | Calories burned |
|---|---|---|
| 15 minutes | 8.8 x 85 x 0.25 | 187 kcal |
| 30 minutes | 8.8 x 85 x 0.5 | 374 kcal |
| 45 minutes | 8.8 x 85 x 0.75 | 561 kcal |
| 60 minutes | 8.8 x 85 x 1 | 748 kcal |
| 90 minutes | 8.8 x 85 x 1.5 | 1122 kcal |
That is about 12.5 kcal per minute of climbing stairs at this weight. A short session still counts: even 15 minutes burns 187 kcal, and three 15-minute sessions across a day add up to the same 561 kcal as one 45-minute session.
How the burn changes with body weight
The MET value stays the same - it describes the activity, not the person - but the calorie total scales with weight, because a heavier body costs more energy to move:
| Body weight | Calories per hour | Calories per 30 minutes |
|---|---|---|
| 55 kg | 484 kcal | 242 kcal |
| 65 kg | 572 kcal | 286 kcal |
| 75 kg | 660 kcal | 330 kcal |
| 85 kg | 748 kcal | 374 kcal |
Two people doing the same activity for the same time can therefore burn quite different amounts, and that is expected - it is physics, not a mistake in the formula. If your weight sits between two rows, your figure sits between the two values.
How climbing stairs compares
Here is climbing stairs against four other activities at the same 85 kg, all using the same MET formula:
| Activity | MET | Calories per hour at 85 kg |
|---|---|---|
| climbing stairs | 8.8 | 748 kcal |
| running at 6 mph | 9.8 | 833 kcal |
| hiking with a backpack | 7.3 | 620 kcal |
| walking uphill | 6 | 510 kcal |
| running at 5 mph | 8.3 | 706 kcal |
Use this table to choose, not to judge. A higher number means a harder session, not a better one: the activity you enjoy and repeat three times a week beats the activity that burns more per hour but that you quit after a fortnight. Mixing intensities across the week - one harder session, two easier ones - is usually more sustainable than doing the hardest activity every time.
Fitting climbing stairs into your week
| Sessions per week | 30 minutes each | 60 minutes each |
|---|---|---|
| 2 sessions | 748 kcal | 1496 kcal |
| 3 sessions | 1122 kcal | 2244 kcal |
| 5 sessions | 1870 kcal | 3740 kcal |
At 8.8 METs, climbing stairs is vigorous-intensity activity, so it counts double toward the widely used adult activity target: 75 minutes of vigorous activity a week is the equivalent of 150 minutes of moderate activity. Three 15-minute stair sessions a week give you 45 vigorous minutes, and burn about 561 kcal a week at 85 kg. Because it is so intense, short bouts spread across the week work better than one long session — ten minutes here and there adds up fast at this burn rate.
How to use the result
Use the whole foot on each step, keep your chest up, and hold the rail lightly for balance rather than pulling yourself up with your arms. Start with short bouts — five minutes of climbing, then walk back down slowly to recover — and build toward continuous 10- to 15-minute sessions. If your building has several floors, one climb to the top and a lift back down is a practical interval session. Wear shoes with grip: stair treads can be slippery, especially outdoors in wet weather. If your knees complain, slow the pace and shorten the sessions rather than stopping altogether; the descent is usually what bothers knees most, so take the lift down when you can. Use the numbers on this page to set realistic expectations rather than to chase a daily total. If you are tracking food as well, add the session's calories to your total daily energy expenditure for that day, and remember that the figure is an estimate with roughly 10-20% uncertainty. Do not eat back every calorie the calculator shows: activity trackers and MET estimates both tend to overstate slightly, and a small margin keeps a weight-loss plan on track. If you are aiming to lose weight, keep the deficit modest - 300-500 kcal a day is a common, sustainable range - and keep your total intake above the safety floors of 1,200 kcal a day for women and 1,500 kcal a day for men unless a healthcare professional advises otherwise.
What the number does NOT tell you
The MET formula is honest about what it measures and silent about the rest. The 8.8 figure is for stair climbing at a fast pace, so a slow climb costs less, and the formula has no way of knowing your speed. It does not account for your fitness level: a fit person burns fewer calories doing the same climb than an unfit person, because their body is more efficient. It does not account for body composition, it does not include the afterburn that follows hard sessions, it does not measure strength, flexibility or balance gained, and it says nothing about how the activity affects your appetite, sleep or mood. It also cannot tell you whether stair climbing is safe for you: if you have a heart condition, joint problems, asthma or any other health concern, check with a healthcare professional before starting a new, intense activity. Use the calorie figure as a planning estimate, and judge the activity by how you feel doing it and whether you keep doing it.
Frequently asked questions
How many calories do I burn climbing stairs for 30 minutes at 85 kg?
About 374 kcal. The maths is 8.8 METs x 85 kg x 0.5 hours = 374 kcal. That is an estimate from the Compendium average for a fast pace — your real burn depends on your fitness, your pace and the stairs. If you weigh more or less than 85 kg, use the weight table above to read your own figure.
Is 10 minutes of stair climbing enough exercise?
Ten minutes burns about 125 kcal at 85 kg, and three 10-minute bouts across a day add up to the same 374 kcal as one 30-minute session. Short bouts count in full toward your weekly activity total, so ten minutes is a genuinely useful session — especially at 8.8 METs, where ten minutes is already vigorous activity.
How does climbing stairs compare with running?
At 85 kg, climbing stairs burns about 748 kcal per hour, more than running at 5 mph (about 706 kcal) and close to running at 6 mph. The difference is impact and practicality: stairs need no running shoes, no route and no warm-up run, and you can do them in an office building. Running covers more distance, stairs build more climbing strength.
Is climbing stairs good for weight loss?
It can help, but only as part of an overall calorie deficit. At 85 kg, an hour of climbing stairs burns about 748 kcal, which is a useful contribution — roughly the energy in a full meal — but weight loss still comes from the total balance of food and activity across the week, not from one session. Aim for a gradual loss of 0.5-1% of body weight per week, and never drop below 1,200 kcal a day (women) or 1,500 kcal a day (men) without medical supervision.
Is climbing stairs bad for your knees?
Going up is usually well tolerated; coming down loads the knees more, because each step brakes your body weight. If your knees are sensitive, climb at a steady pace, take the lift down, keep sessions short to begin with, and build up gradually. Sharp or persistent knee pain is a reason to see a clinician rather than push through it.
Estimates only, not medical advice. Minimum safe intakes: 1,200 kcal/day women, 1,500 kcal/day men - consult a healthcare professional before a very-low-calorie diet.
