Stair Climbing Calories Formula

The stair climbing calories calculator uses a different formula depending on the mode you choose.

Flights climbed

Calories = Weight_kg * Flights * 0.116

Individual steps climbed

Calories = Weight_kg * Steps * 0.0097

Stairmaster or timed stair climbing

Calories = MET * Weight_kg * (Minutes / 60)

Unit conversion

Weight_kg = Weight_lb * 0.45359237
  • Calories: estimated energy burned, in kilocalories.
  • Weight_kg: your body weight in kilograms.
  • Weight_lb: your body weight in pounds.
  • Flights: number of flights climbed. The calculator treats 1 flight as about 10 feet of rise, or about 12 steps.
  • Steps: number of individual stairs climbed.
  • MET: exercise intensity value. Higher MET means harder effort.
  • Minutes: time spent climbing stairs or using a Stairmaster.

Use Flights mode when you know how many floors or flights you climbed. Use Steps mode when you counted individual stairs. Use Stairmaster mode when you know the workout time and intensity.

The calculator also shows kilojoules and a body fat equivalent. These are estimates based on:

kJ = Calories * 4.184
Body_fat_g = Calories / 7.7

Typical Stair Climbing Values

Input type Typical assumption Used for
1 flight About 10 ft or 3 m of vertical rise Flights mode
1 flight About 12 individual steps Comparing flights to steps
1 step About 0.25 m of vertical rise Steps mode
Stair activity MET value How to interpret it
Slow stair walking 4 Easy effort
Brisk stair climbing 6 Moderate to hard effort
Hard Stairmaster workout 8.8 Vigorous effort
Running up stairs 15 Very hard effort

Stair Climbing Calories Examples

Example 1: Calories burned climbing flights

You weigh 160 lb and climb 10 flights.

First convert pounds to kilograms:

Weight_kg = 160 * 0.45359237 = 72.57

Then calculate calories:

Calories = 72.57 * 10 * 0.116 = 84.2

You burned about 84.2 kcal.

Example 2: Calories burned on a Stairmaster

You weigh 70 kg and climb for 20 minutes at a brisk 6 MET pace.

Calories = 6 * 70 * (20 / 60) = 140

You burned about 140 kcal.

Stair Climbing Calories FAQ

How many calories do you burn climbing one flight of stairs?

It depends on your weight. Using the calculator formula, one flight burns:

Calories per flight = Weight_kg * 0.116

For a 70 kg person, that is about 8.1 kcal per flight. For a 90 kg person, it is about 10.4 kcal per flight.

Why does body weight change the result?

Stair climbing lifts your body upward against gravity. A heavier body requires more energy to move up the same height. That is why the formulas multiply by body weight in kilograms.

Are calories from a Stairmaster the same as calories from real stairs?

They are close estimates, but not identical. Real stairs depend on step height, pace, balance, and whether you use the handrail. A Stairmaster estimate depends on time and MET intensity. If you use the handrails heavily, the actual calories burned may be lower than the displayed estimate.
