Calories Burned Treadmill Walking: Chart by Weight and Calculator
Last updated
This page provides calorie estimates for treadmill walking based on standard metabolic equivalents. The table calculates your burn using a standard formula based on these equivalents, your body weight, and duration.
These numbers are only estimates for a typical adult. Your actual energy expenditure varies depending on your current fitness level, body composition, walking technique, and how hard you actually work. Even fitness trackers rely on estimates, so use these figures as a helpful baseline rather than an exact measurement.

Calculate your own estimate
The formula. kcal = MET × 3.5 × body weight in kg ÷ 200 × minutes.
Worked example. Walking, treadmill, 3.5 to 3.9 mph (5.6 to 6.3 km/h), 0% grade: 4.8 × 3.5 × 68.0 kg (150 lb) ÷ 200 × 30 min = about 171 kcal.
Which row is you?
The table separates treadmill walking by your speed in miles per hour or kilometers per hour. To find your match, look at the console on your machine and pick the row that aligns with your pace. All options assume a flat surface with a zero percent grade. If you walk at a brisk pace, you will select a row further down the chart. Since the machine dictates your speed, simply read the display and find the closest match to estimate your effort.
What changes the real number
- Your specific body composition, including your ratio of muscle to fat.
- Your walking technique and stride efficiency on the moving belt.
- Your baseline cardiovascular fitness level and how hard you actually work.
- Whether you hold onto the handrails, which reduces your total effort.
Practical tips
- Walk with a natural arm swing instead of gripping the handrails to get a more accurate estimate of your effort.
- Start at a slower pace to warm up your muscles before increasing the belt speed to your target pace.
- Attach the safety clip to your clothing every time you step on the belt to prevent falls.
About these numbers. MET values describe the average energy cost of an activity for adults; your own burn can be noticeably higher or lower. The values include resting energy use, so the extra calories from exercise are a little lower than the total shown. A separate Older Adult Compendium exists for people aged 60 and over.

When to stop and see a doctor
- Sudden chest pain or heavy pressure that spreads to your arms or jaw.
- Severe dizziness, lightheadedness, or feeling like you might pass out.
- Unusual shortness of breath that feels out of proportion to your walking pace.
