ACSM (auto walk/run)
Walk equation ≤ 4.5 mph, run equation above
The incline row shows extra calories from grade versus the same speed on flat ground.
A treadmill burns the same calories as overground walking or running at the same speed and grade. Incline adds a large share without extra speed.
This calculator picks the ACSM walking or running equation automatically by speed and shows the incline contribution.
How to calculate treadmill calories
To calculate treadmill calories, set speed and incline; the calculator applies the correct ACSM equation and isolates the incline's effect. Machine displays often overstate the burn.
Worked example: 3.5 mph at 3% incline for 45 minutes at 70 kg burns about 280 calories.
Frequently asked questions
No, most read 15–30% high because they ignore your true weight and efficiency. An equation-based estimate is closer.
Yes. A 5–10% incline can add 30–50% to the calorie burn at the same speed.
No, if you want the calorie estimate to hold. Holding on offloads work and lowers the real burn below the display.
