Calorie Burn Calculator

Our calorie burn calculator helps you estimate the number of calories you burn during various physical activities and exercises. Understanding your calorie expenditure is essential for creating an effective weight loss or fitness plan.

How Calories Are Burned

Calorie burn depends on several factors:

  • Body weight: Heavier individuals burn more calories
  • Activity intensity: Higher intensity = more calories burned
  • Duration: Longer activities burn more total calories
  • Fitness level: Trained individuals may be more efficient (burn slightly fewer calories)
  • Metabolic rate: Individual variations in metabolism

Calorie Burn by Activity (70kg / 154lb Person)

Activity Calories per 30 min Calories per Hour Intensity
Walking (4 km/h) 120 240 Low
Jogging (8 km/h) 300 600 Moderate-High
Running (12 km/h) 450 900 High
Cycling (moderate) 260 520 Moderate
Swimming (laps) 300 600 Moderate-High
Strength Training 180 360 Moderate
HIIT Workout 400 800 Very High
Yoga (Hatha) 120 240 Low-Moderate

MET (Metabolic Equivalent) Values

MET values are used to estimate calorie burn:

Formula: Calories Burned = MET × Weight (kg) × Duration (hours)

Common MET Values

  • Sleeping: 0.9 MET
  • Sitting: 1.0 MET
  • Walking (slow): 2.0 MET
  • Walking (brisk): 3.5 MET
  • Running (8 km/h): 8.0 MET
  • Running (12 km/h): 12.0 MET
  • Cycling (moderate): 6.8 MET
  • Swimming (moderate): 8.0 MET

Example Calorie Burn Calculations

Example 1: 60-Minute Jog

  • Person: 70kg, Activity: Jogging (8 MET)
  • Calculation: 8 × 70 × 1 = 560 calories

Example 2: 45-Minute Strength Training

  • Person: 65kg, Activity: Strength Training (5 MET)
  • Calculation: 5 × 65 × 0.75 = 244 calories

Maximizing Calorie Burn

Strategies for Higher Calorie Expenditure

  • Increase intensity: Add intervals or tempo work
  • Add resistance: Use weights, hills, or resistance bands
  • Extend duration: Longer sessions burn more total calories
  • Build muscle: More muscle = higher resting metabolic rate
  • Stay active throughout day: Increase NEAT (non-exercise activity thermogenesis)

⚠️ Common Mistakes

  • Overestimating burn: Fitness trackers can overestimate by 20-30%
  • "Earning" extra food: Eating back all exercise calories prevents deficit
  • Ignoring diet: You can't out-exercise a bad diet (1 hour run ≈ 1 burger)
  • Only focusing on cardio: Strength training builds muscle, increasing daily burn

Daily Activity Calorie Burn

Beyond structured exercise, daily activities contribute significantly:

Activity Calories per Hour (70kg person)
Sleeping 63
Sitting/Office Work 70-100
Standing 100-130
Light Housework 170-220
Gardening 250-350
Playing with Kids 200-300

Frequently Asked Questions

How many calories do I burn a day?

Total daily calorie burn (TDEE) varies widely: 1,600-2,200 for women and 2,200-3,000 for men, depending on body size, age, and activity level. Use a TDEE calculator for personalized results.

Which exercise burns the most calories?

Running, swimming, and HIIT workouts typically burn the most calories per hour (600-1,000+). However, the "best" exercise is one you'll do consistently.

Should I eat back calories burned from exercise?

If your calorie target already includes your activity level, don't eat back exercise calories. If you calculated based on sedentary TDEE, you can eat back 50-75% of exercise calories.
