How Many Calories Does Running on a Treadmill Burn?
Discover how many calories you burn running on a treadmill at different speeds. Learn the science behind treadmill calories burned and use our calculator for exact results.
If you've ever wondered how many calories does running on a treadmill burn, you're not alone. It's one of the most common questions for anyone looking to lose weight or track their fitness progress. The short answer? A 70 kg (154 lb) person burns approximately 317 calories jogging at 8 km/h (5 mph) for 30 minutes—but your actual burn depends on several factors.

The Formula Behind Treadmill Calorie Burn
Understanding how treadmill calories burned are calculated helps you optimize your workouts. Our calculator uses the ACSM (American College of Sports Medicine) metabolic equations, which estimate your oxygen use from speed and incline:
- Running: VO2 = 0.2 × S + 0.9 × S × G + 3.5
- Walking: VO2 = 0.1 × S + 1.8 × S × G + 3.5
- Calories per minute = VO2 × Weight (kg) ÷ 1000 × 5
S is speed in metres per minute (km/h × 16.67) and G the incline as a fraction (5% = 0.05). The MET value, how much energy an activity requires compared to resting, is VO2 ÷ 3.5. Running costs about twice as much per unit of speed as walking, which is why jogging burns so much more than a brisk walk.
Calories Burned at Different Speeds
Here's a breakdown of calories burned running on treadmill at various speeds for a 70 kg (154 lb) person during a 30-minute workout at 0% incline:
| Speed | Activity | MET | Calories (30 min) |
|---|---|---|---|
| 5 km/h (3.1 mph) | Walking | 3.4 | ~124 kcal |
| 6 km/h (3.7 mph) | Brisk Walking | 3.9 | ~142 kcal |
| 8 km/h (5 mph) | Jogging | 8.6 | ~317 kcal |
| 10 km/h (6.2 mph) | Running | 10.5 | ~387 kcal |
| 12 km/h (7.5 mph) | Fast Running | 12.4 | ~457 kcal |
As you can see, the difference between walking and running is substantial. Calories burned jogging treadmill workouts at 8 km/h burn nearly twice as many calories as walking at 5 km/h.
Heart Rate and Calorie Burn
Your heart rate is directly connected to how many calories you burn. Higher MET activities require your heart to pump more blood and oxygen to your muscles, which is why heart rate monitors can estimate calorie burn.
Here's how heart rate zones typically correlate with treadmill exercise:
- Zone 1 (50-60% max HR): Light walking, MET 2-3
- Zone 2 (60-70% max HR): Brisk walking to light jog, MET 4-6
- Zone 3 (70-80% max HR): Jogging to moderate running, MET 6-9
- Zone 4 (80-90% max HR): Fast running, MET 9-12
- Zone 5 (90-100% max HR): Sprint intervals, MET 12+
While our treadmill calorie calculator doesn't require heart rate input, it uses MET values that correspond to typical heart rate responses at each speed.
Factors That Affect Your Burn
Several factors influence how many calories you burn on a treadmill:
Body Weight
Heavier individuals burn more calories doing the same activity. A 90 kg person burns approximately 29% more calories than a 70 kg person at the same speed and duration.
Incline
Adding incline significantly increases calorie burn. The ACSM running equation adds 0.9 × speed × grade to your oxygen cost. For example:
- 0% incline at 8 km/h: MET 8.6
- 5% incline at 8 km/h: MET 10.3 (+20% more calories)
- 10% incline at 8 km/h: MET 12.0 (+40% more calories)

Duration
Longer workouts burn more total calories, but the rate remains consistent. A 60-minute jog burns exactly twice as many calories as a 30-minute jog at the same intensity.
Fitness Level
More fit individuals may burn slightly fewer calories at the same workload because their bodies have become more efficient. However, this difference is relatively small and shouldn't discourage you from exercising.
Calorie Burn Comparison Chart
Use this quick reference chart for treadmill calories burned at common speeds and weights (30 minutes, 0% incline):
| Speed | 60 kg (132 lb) | 70 kg (154 lb) | 80 kg (176 lb) | 90 kg (198 lb) |
|---|---|---|---|---|
| 5 km/h (Walking) | 107 kcal | 124 kcal | 142 kcal | 160 kcal |
| 8 km/h (Jogging) | 272 kcal | 317 kcal | 362 kcal | 407 kcal |
| 10 km/h (Running) | 332 kcal | 387 kcal | 442 kcal | 497 kcal |
| 12 km/h (Fast) | 392 kcal | 457 kcal | 522 kcal | 587 kcal |

How to Maximize Your Treadmill Calorie Burn
If your goal is to burn more calories during your treadmill sessions, consider these strategies:
1. Add Incline Training
Walking or running at an incline dramatically increases calorie burn without requiring faster speeds. This is especially useful for those with joint concerns who want to avoid high-impact running. A 10% incline adds about 40% to your calorie burn when running and more than doubles it when walking.
2. Try Interval Training
Alternating between high and low intensities keeps your heart rate elevated and can increase total calorie burn compared to steady-state cardio. Try 1-minute sprints followed by 2-minute recovery jogs.
3. Increase Duration Gradually
If you're currently doing 20-minute sessions, work your way up to 30, then 45 minutes. Every additional minute adds to your total burn.
4. Don't Hold the Handrails
Holding onto the treadmill handrails reduces your calorie burn by up to 20-25% because it supports your body weight and reduces the effort required.
5. Swing Your Arms
Natural arm movement engages more muscles and slightly increases energy expenditure compared to keeping your arms still.
Conclusion
The number of calories burned running on a treadmill varies based on your speed, weight, incline, and workout duration. Using the ACSM equations, you can expect to burn anywhere from about 125 calories for a light 30-minute walk to over 500 calories for an intense running session.
