Key Takeaways
- Treadmill elevation gain = distance × grade percentage. A 5% grade over 3 miles equals approximately 792 ft of vertical gain.
- Incline running increases calorie burn by approximately 3–5% per 1% of grade above flat.[1]
- The solve-for mode lets you calculate any one of {elevation, distance, grade} given the other two values.[2]
How the Calculation Works
The fundamental relationship is:
elevation(m) = distance(km) × 1000 × (grade% ÷ 100)
The calculator can solve for any of the three variables. Grade in degrees is derived as: degrees = arctan(grade% ÷ 100).

Limitations and Important Notes
- The extra calorie burn estimate (≈4% per 1% grade) is an approximation from treadmill research and may vary based on speed and individual biomechanics.[3]
- Treadmill incline accuracy varies by machine quality and calibration.
