Calories Burned Climbing 100 Stairs

Stairs are tiny hills you can reach every day. The burn comes from lifting your body against gravity. Two things drive the number: your body weight and the direction of travel. Up costs far more energy than down. Pace and technique nudge the total too, though the per-step cost doesn’t swing wildly for short bouts.

To anchor the math, researchers measured the energy of real stair climbing in a lab. Their results boil down to a simple rule of thumb: about 0.15 kilocalories per step going up and 0.05 per step going down for a 70-kilogram body. You can scale that by weight. If you weigh less, the figure drops in the same proportion; if you weigh more, it rises in the same proportion. A classic per-step study also reported the combined cost of going up one step and down one step at roughly 0.20 kilocalories for the same body mass.

What 100 Stairs Looks Like In Calories

Use the chart below to find a quick estimate. The totals use the per-step method above and round to one decimal place. “Up” means 100 steps climbed. “Down” means 100 steps descended. Many people do both on a staircase, so you’ll also see how to pair them in the paragraph that follows.

Body Weight	100 Up (kcal)	100 Down (kcal)
50 kg	10.7	3.6
55 kg	11.8	3.9
60 kg	12.9	4.3
65 kg	13.9	4.6
70 kg	15.0	5.0
75 kg	16.1	5.4
80 kg	17.1	5.7
90 kg	19.3	6.4
100 kg	21.4	7.1
110 kg	23.6	7.9

If you climb 100 and walk back down the same 100, total burn for a 70-kilogram person lands near 20 kilocalories. Lighter bodies land lower; heavier bodies land higher. A backpack adds weight and nudges the number upward. A handrail lightens the workload a touch.

How Pace Fits In

Any short climb will take only a minute or two. Cadence (steps per minute) is a handy way to picture pace. Research on stair sessions places common training ranges around 60–120 steps per minute. That’s a slow steady climb up to a breathy power effort. The intensity label you see on charts—called METs—lines up with that change in pace.

The Compendium of Physical Activities lists stair climbing around 4.0 MET at a slow pace, about 6.8 MET for a general climb, and about 8.8 MET for a fast climb. MET means “how many times above resting.” One MET is roughly one kilocalorie per kilogram per hour. So, a 70-kilogram person working at 6.8 MET for one hour expends about 476 kilocalories. For a tiny bout like 100 steps, you’re only using a slice of that hour, which is why short bursts feel tough yet don’t rack up big time-based totals unless you string sets together.

To keep the math tidy, this guide leans on the per-step method for 100-step estimates and on METs when you plan time-based sessions. Both come from the same physiology—oxygen use and body mass—and they agree nicely once you match pace and time.

Taking 100 Stairs: Calories Burned With And Without The Descent

Say your stairwell has eight or nine steps per flight. That’s around twelve flights to reach 100 steps up. If you turn around and walk back down those same steps, you’ll rack up two hundred total steps. Using the lab-tested per-step rule, the combined up-and-down pass comes out near 20 kilocalories for a 70-kilogram person, near 23 for 80 kilograms, and near 29 for 100 kilograms. Small tweaks change the math: two-at-a-time strides raise intensity; skipping the rail keeps more of your body weight on each step.

How To Estimate Your Own Burn

Per-Step Method

Use these two lines:

Up Steps

Calories ≈ 0.15 × (your weight in kg ÷ 70) × number of steps up

Down Steps

Calories ≈ 0.05 × (your weight in kg ÷ 70) × number of steps down

Add the two parts for a total. This method shines for short bouts because it ties directly to steps, not minutes. It also adjusts cleanly for a backpack: add the pack’s weight to your body weight in the formula. If your stairs mix in short ramps or platforms, just count the steps you take; the math remains straightforward.

Worked Example

You weigh 75 kilograms. You climb 100 and walk down 100. Up = 0.15 × (75 ÷ 70) × 100 ≈ 16.1 kcal. Down = 0.05 × (75 ÷ 70) × 100 ≈ 5.4 kcal. Total ≈ 21.5 kilocalories.

Why Up Beats Down

Going up is a lift against gravity, so your muscles must raise your center of mass on each step. Going down is mostly controlled lowering. The energy gap shows up in lab data and in real stairwell sessions. That gap is also why stairs feel like leg day when you live on the fifth floor. If your knees get cranky on the descent, slow the rhythm and touch the rail to soften impacts.

Where MET Charts Still Help

Planning a session by minutes instead of step counts? MET charts give you a quick way to forecast calories for longer blocks. Multiply MET × body weight × hours. Then pick an intensity that fits your plan. If you’re stacking short bursts through the day, a cadence near 60–90 steps per minute feels doable for most people once they warm up. For a bigger cardio block, you might use a steady climb for 10–20 minutes and match it against the Harvard 30-minute list to sanity-check your numbers.

Here’s a quick MET math sketch for a 70-kilogram person: 6.8 MET × 70 kg × (15 minutes ÷ 60) ≈ 119 kilocalories for a quarter-hour of steady stairs. Double the time for roughly double the burn. Those numbers sit nicely beside the per-step method if you like to count flights rather than steps during longer efforts.

Pace And Time Guide For 100 Steps

Here’s a simple pace guide you can tape near your workstation or stick on your phone. The times assume a steady rhythm with short landings. Your staircase and footwork may vary a little.

Pace & MET	Cadence	Time For 100 Steps
Slow (4.0 MET)	~60 spm	~1 min 40 sec
Steady (6.8 MET)	~90 spm	~1 min 7 sec
Fast (8.8 MET)	~120+ spm	~50–55 sec

Stair Details That Change The Math

Step Height

Most steps range between 15–20 cm (about 6–8 inches). Taller steps raise your body a bit more each time, so the per-step cost creeps up. Across just 100 steps, the swing stays modest. Over long climbs—say hundreds of steps—the taller design will add up.

Flight Length

Short flights force frequent turnarounds. That can slow cadence and slightly reduce total work per minute. Long flights feel smoother and make it easier to settle into a rhythm. Both still count toward your daily activity target.

Two-At-A-Time Bursts

Big steps demand more force from the hips and quads. Use them in short bursts. If your knee grumbles, go back to single steps and use the rail for a while.

Load And Shoes

A small backpack bumps body mass and burn. Grippy shoes keep traction when stair treads are dusty or wet, which makes each step feel safer and snappier.

Stairs Versus Quick Alternatives

Stairs pack a punch because they fold resistance into cardio. A two-minute stair pass at a steady pace can match the calorie burn of a brisk one-third-mile walk for many bodies. If your building lacks stairs, steep hill repeats feel similar. To round out weekly activity, the CDC adult activity guidance suggests 150 minutes of moderate cardio a week plus two days of strength work. Short stair bites add toward that weekly target and give your legs a strength boost at the same time.

Mini Workout Ideas With 100 Steps

Office Ladder

Every hour, climb 25 up and walk back down. Four rounds bring you to 100 up and 100 down without breaking your day.

Errand Booster

When you park or hop off the bus, add a quick 50 up. Repeat on the way home. If time is tight, do two fast rounds of 25.

Stair Sandwich

Before a strength session, use 100 up as a warm-up. After the last set, finish with an easy 100 down to cool off.

Common Missteps To Avoid

Half-Foot Landings

Hanging heels off the edge stresses the calves and Achilles. Place the whole forefoot on the tread when space allows.

Rushing The Descent

Most slips happen on the way down. Keep your eyes on the treads, plant softly, and use the rail in busy stairwells.

Holding Your Breath

A steady rhythm helps. Try an inhale for two steps and an exhale for two steps on easy climbs. Switch to one-one during short hard pushes.

When To Keep It Easy

If you’re new to stairs, pick a mild pace and shorter sets on day one. If you’re feeling joint pain, dizziness, or chest tightness, switch to gentle walks and talk with a clinician before you ramp things up. Comfort beats bravado on stairwells.

Bottom Line

For 100 steps, the math stays simple: about 15 kilocalories up and about 5 kilocalories down at 70 kilograms, scaled by your weight. That’s quick, clear, and handy for daily tracking. Build from there, stay safe on the descent, and let the sessions add up daily.
