How it works
kcal = walkingMET(speed, incline%) × weight(kg) × hours
Treadmill calories by incline (170 lb, 3.0 mph, 30 min)

Based on 170 lb body weight, 3.0 mph, 30-minute session. Each 2% of incline meaningfully raises calorie burn.
Frequently asked questions
How many calories does a treadmill burn?
A 170 lb person walking at 3.0 mph on a flat treadmill for 30 minutes burns roughly 125–130 calories. Add a 6% incline and that climbs to about 220–225 calories — roughly 75% more for the same speed and time.
Does treadmill incline really burn more calories?
Yes — significantly. The ACSM equation shows that each 1% of grade adds roughly the same metabolic load as a small speed increase. Walking at 3 mph on a 10% incline burns nearly double the calories of flat walking at the same speed.
How is treadmill calorie burn calculated?
This calculator uses the ACSM walking metabolic equation: METs × weight(kg) × hours, where METs = (0.1·v + 1.8·v·grade + 3.5) / 3.5, v in m/min. Speed and incline both raise METs. Note: holding the handrails reduces your real calorie burn below this estimate.
