Calories Burned Walking on a Treadmill (With Chart)

How many calories you burn walking on a treadmill depends mainly on your body weight, your speed and the incline. The table below gives realistic estimates for a 30-minute session, so you can plan workouts around your goals.

Calories burned in 30 minutes on a treadmill

Estimates use standard walking and running MET values from the Compendium of Physical Activities (calories per minute = MET × 3.5 × body weight in kg ÷ 200). Your actual burn varies with fitness, age and how much you hold the handrails.

What affects how many calories you burn

• Body weight: moving a heavier body takes more energy.
• Speed: going from 2.5 to 3.5 mph raises the burn by around 40%.
• Incline: the biggest lever for walkers. A moderate incline can nearly double the burn of flat walking at the same speed. See our incline treadmill guide.
• Handrails: holding on supports part of your weight and reduces the calories burned.
• Consistency: four 30-minute walks a week add up to far more than one long session.

Is the treadmill console calorie count accurate?

Treadmill consoles often overestimate, especially if you have not entered your weight. Treat the number as a rough guide and use the same machine and settings to compare workouts over time. A chest-strap heart rate monitor gives a better estimate.

Easy ways to burn more calories walking

1. Add 3–5% incline before increasing speed.
2. Try intervals: 2 minutes brisk, 1 minute easy, repeated.
3. Swing your arms naturally and let go of the rails.
4. Add one longer walk each week.
5. Build up to longer incline walks of 20–30 minutes once you are comfortable.

For full plans, see our treadmill workouts guide. If you walk more than you run, our walking treadmill guide explains which features matter.

Frequently asked questions

How many calories does walking 1 mile on a treadmill burn?

Roughly 80–120 calories for most adults on a flat belt, depending on weight. Heavier walkers and walkers on an incline burn more.

Is walking on a treadmill good for weight loss?

Yes, when it is combined with a sensible diet. Brisk or incline walking is easy to stick to and gentle on the joints.

Does walking on an incline burn more calories than running?

Steep incline walking can match easy jogging for calories, with less impact. Running at higher speeds still burns more per minute.
