Key Takeaways
- The Compendium provides 11 distinct stair climbing MET values ranging from 3.5 (descending) to 12.0 (carrying >74 lb).[1]
- General stair climbing (6.8 MET) estimates approximately 83 kcal in 10 minutes for a 70 kg person.[2]
- Descending stairs (3.5 MET) burns approximately 51% of the calories compared to ascending at general pace (6.8 MET).[1]
- A stair machine (9.0 MET) estimates approximately 32% more calories per minute than general stair climbing (6.8 MET).[3]
- These are informational estimates for personal awareness and journaling. Individual results vary with step height and pace.

| Carrying >74 lb Load | 12 | 116 | 147 | 179 | 210 |
How the Estimate Works
The calculator uses the standard MET formula with climb-type-specific MET values from the Compendium:[1]
Calories = (MET × 3.5 × Wt_kg × Duration_min) ÷ 200
Time-based mode applies the climb MET for the entered duration. Flight-based mode converts flights to approximate duration using ~10 seconds per flight at moderate pace, then applies the MET formula.
Climb Types Explained
General Climbing (6.8 MET)
Normal-pace stair climbing, one step at a time. The standard benchmark for everyday stair use (Compendium code 17133).[1]
Fast Climbing (9.3 MET)
Fast-paced single-step climbing. Vigorous intensity that significantly increases caloric demand (code 17134).[1]
Two Steps at a Time (7.5 MET)
Skipping steps by taking two at a time. Requires more leg power per step but covers ground faster (code 17135).[1]
Descending Stairs (3.5 MET)
Walking down stairs at normal pace. Burns approximately half the calories of ascending. Included for round-trip estimates (code 17136).[1]
Stair Machine (9.0 MET)
Gym stair climber machine at general effort. Continuous stepping without the flat-landing rest of real stairs (code 02065).[1]
Load Carrying (5.5-12.0 MET)
The Compendium provides 5 load brackets from 1-15 lb (5.5 MET) to >74 lb (12.0 MET), reflecting the significant impact of load on stair climbing effort.[1]
Flights, Floors & Steps
A standard flight of stairs typically has 12-20 steps, with 16 being the most common in residential and commercial buildings. Key conversions:
- 1 floor ≈ 1 flight in most buildings (though some tall-ceilinged buildings may have 2 flights per floor)
- 16 steps × 7 inches per step = approximately 9.3 feet of vertical rise per flight
- 10 flights ≈ 160 steps at the default 16 steps/flight setting
The flight-based mode assumes approximately 10 seconds per flight at a moderate climbing pace. Adjust steps-per-flight to match your specific staircase.
