Holding the rails?
Lowers real burn—this assumes normal arm swing.

About this calculator
How to use Treadmill Calorie Calculator, plus the formulas and logic behind the results.
Tool description
Incline and speed raise oxygen cost on a treadmill. This uses a VO2-based estimate converted to MET and calories.
How to use
- Set treadmill to average speed/incline used.
- Log duration and body weight.
- Calculate kcal.
- Compare sessions with same inputs.
Formulas & reference
VO2 from speed + incline (ACSM-style)MET = VO2 ÷ 3.5Calories = MET × kg × hours
Incline tips
- 1–3% mimics outdoor air resistance for runners
- Steep incline walking burns more per mph
- 0% still burns at any speed > walk
- Cool down 3–5 min after hard inclines
Calculation logic
Horizontal and vertical speed components estimate VO2, convert to MET, multiply by mass and time.
Handrails, holding on, and motor assist on some machines reduce actual effort.
Treadmill Calorie Calculator FAQ
Common questions about this calculator and how to use the results.
Run vs walk?
Same formula if you enter actual speed; running speeds raise VO2 sharply.
KPH treadmill?
Convert: mph = kph ÷ 1.609344.
Machine calorie display?
Often optimistic; this is another estimate to compare trends.
Weight vest?
Add vest weight to body weight for better estimate.
12% incline?
Enter exact %—steep hills dramatically raise burn.
