About this calculator
About the Calories Burned Calculator
Understanding how many calories you burn during exercise and daily activities is essential for managing your weight, planning your nutrition, and tracking fitness progress. Our calories burned calculator uses MET values (Metabolic Equivalents of Task) — the scientific standard used by exercise physiologists and the World Health Organization — to provide accurate estimates for over 500 different activities.
Unlike generic estimates that assume everyone burns the same number of calories, our calculator factors in your body weight, the specific activity, and its intensity level. A 200-pound person burns significantly more calories walking a mile than a 120-pound person, and our calculator accounts for this difference precisely.
What Are MET Values?
A MET value represents the ratio of your working metabolic rate to your resting metabolic rate. One MET is defined as the energy you burn at rest — approximately 1 calorie per kilogram of body weight per hour.
| Activity | MET Value | Description |
|---|---|---|
| Sitting quietly | 1.0 | Baseline resting metabolism |
| Walking slowly (2 mph) | 2.0 | Light strolling |
| Walking briskly (3.5 mph) | 4.3 | Purposeful walking |
| Light cycling | 6.0 | Leisurely bike ride |
| Jogging (5 mph) | 8.0 | Moderate running pace |
| Swimming laps | 8.0 | Moderate effort |
| Running (6 mph) | 9.8 | 10-minute mile pace |
| High-intensity interval training | 11.0 | HIIT workouts |
| Jumping rope | 12.3 | Vigorous skipping |
| Sprinting | 15.0 | Maximum effort running |
Formula: Calories burned per minute = (MET × 3.5 × weight in kg) ÷ 200
Understanding the Afterburn Effect (EPOC)
After intense exercise, your body continues burning extra calories at an elevated rate for hours. This is called Excess Post-exercise Oxygen Consumption (EPOC).
| Activity Type | EPOC Duration | Extra Calories Burned |
|---|---|---|
| Low-intensity steady state (LISS) | 0-30 minutes | Minimal |
| Moderate-intensity cardio | 30-60 minutes | 5-10% of workout burn |
| High-intensity interval training (HIIT) | 2-24 hours | 10-15% of workout burn |
| Heavy resistance training | 24-48 hours | 10-15% of workout burn |
Example: A 60-minute HIIT session that burns 600 calories during the workout may burn an additional 60-90 calories over the next several hours through EPOC.
How the Calculator Works
Calculation Method
This calculator uses the MET (Metabolic Equivalent) Formula:
Calories Burned = (MET × 3.5 × Weight in kg) ÷ 200 × Duration in minutes
Where:
- MET = The metabolic equivalent for your selected activity
- 3.5 = The oxygen consumption at rest (constant)
- Weight in kg = Your body weight converted to kilograms
- Duration = The number of minutes spent performing the activity
- 200 = A constant conversion factor
Step 1: Select Your Activity
Choose from hundreds of activities organized by category:
- Cardio and running
- Cycling and spinning
- Swimming and water sports
- Strength training and CrossFit
- Yoga and Pilates
- Sports (basketball, tennis, soccer, golf)
- Outdoor activities (hiking, skiing, rock climbing)
- Household chores and gardening
- Occupational activities
Step 2: Enter Your Weight
Calories burned are directly proportional to body weight. Heavier individuals burn more calories performing the same activity because their bodies require more energy to move.
Step 3: Enter Duration
Input the number of minutes you performed the activity. The calculator multiplies the per-minute burn rate by your total time.
Step 4: View Your Results
The calculator instantly shows your estimated calories burned based on the MET value for your selected activity, your body weight, and workout duration.
Formula
Calories Burned = MET × Weight (kg) × Duration (hours)
MET (Metabolic Equivalent) varies by activity:
- Walking (3.5 mph): 3.5 MET
- Running (6 mph): 9.8 MET
- Cycling (12-13 mph): 8.0 MET
- Swimming: 8.0-10.0 MET

Best for Beginners
If you are new to exercise, consistency matters more than intensity. Walking, light cycling, and swimming are sustainable activities that burn meaningful calories without excessive strain.
Best for Time-Constrained People
HIIT workouts provide maximum calorie burn in minimal time. A 20-minute HIIT session can burn as many calories as 40 minutes of moderate steady-state cardio, plus additional EPOC benefits.
Common Mistakes When Estimating Calorie Burn
Trusting Gym Machine Displays
Treadmills, ellipticals, and bikes often overestimate calorie burn by 15-30%. They rarely account for individual factors like fitness level, body composition, and efficiency.
Ignoring Rest Periods
If you do 60 minutes at the gym but rest 2 minutes between every set, your actual active time may be only 40 minutes. Log only the time you are actively exercising.
Overestimating Intensity
That "brisk walk" might actually be a leisurely stroll. Be honest about your effort level for accurate estimates.
Counting Daily Steps as Exercise
Steps taken throughout the day are already included in your TDEE activity multiplier. Counting them again as "exercise" leads to double-counting calories.
Using Calorie Burn Data for Weight Management
Creating a Calorie Deficit
To lose one pound of fat per week, you need a 500-calorie daily deficit. You can achieve this through:
- Diet alone: Eat 500 calories below TDEE
- Exercise alone: Burn 500 extra calories daily
- Combined approach: Eat 250 fewer calories + burn 250 extra calories
Fueling Your Workouts
If you are eating at maintenance or in a surplus:
- Before cardio (1-2 hours): Light meal with carbs and moderate protein
- Before strength training (1-2 hours): Meal with protein and complex carbs
- After any workout (within 2 hours): 20-40 grams of protein plus carbs
Step-by-Step Example
Example Calories Burned
- Activity: Running at 8 mph (11.5 MET)
- Body Weight: 70 kg
- Duration: 1 hour
- Calories Burned = 11.5 × 70 × 1 = 805 calories
Frequently Asked Questions
How accurate are calorie burn calculators?
Calculators using MET values are accurate within 10-15% for most people. The biggest variables are individual fitness level (fitter people burn fewer calories doing the same activity) and body composition.
Do I burn more calories if I am unfit?
Paradoxically, yes. Less fit individuals often burn more calories performing the same activity because their bodies are less efficient. As you get fitter, your calorie burn for the same workout may decrease slightly.
Does sweating more mean I burned more calories?
No. Sweating is your body's cooling mechanism and depends on temperature, humidity, and genetics. You can burn significant calories without sweating much (swimming, cold-weather walking).
Should I eat back the calories I burn?
If your goal is weight loss and you already calculated a calorie target, eating back all exercise calories can cancel your deficit. A conservative approach is to eat back 50% of estimated exercise calories or none at all.
What burns more calories: cardio or weights?
Cardio typically burns more calories per minute during the activity. However, weight training increases muscle mass, which raises your resting metabolic rate over time. For long-term weight management, both are important.
Why do different sources give different calorie burn estimates? Exercise calorie burn varies by fitness level, intensity, body composition, and individual metabolism. Estimates can vary by ±20-30%. Use as a general guide rather than precise measurement.

Frequently Asked Questions
How does the calories burned calculator estimate energy expenditure?
The calculator uses MET (Metabolic Equivalent of Task) values — a standardized measure of the energy cost of an activity relative to rest. It multiplies the MET value for your chosen activity by your weight in kilograms and the duration in hours to estimate calories burned. Heavier individuals burn more calories performing the same activity for the same duration.
What activities can I select in this calculator?
The calculator covers a wide range of activities including aerobic exercise (running, cycling, swimming), strength training, sports, daily activities (walking, cleaning, gardening), and more. Each activity has an assigned MET value based on research from the Compendium of Physical Activities.
Why does my weight affect how many calories I burn?
Physical work requires moving your body mass against gravity and friction. A heavier person must expend more energy to perform the same movement — whether walking, running, or cycling. This is why the calculator requires your weight as a key input. Calorie estimates will be higher for heavier individuals and lower for lighter ones, even with identical activity and duration.
How accurate are calorie burn estimates from this calculator?
MET-based calculations are a population-level estimate and vary by individual. Fitness level, exercise efficiency, terrain, temperature, and individual metabolic variation all affect actual calorie burn. Wearable fitness trackers and heart rate monitors can improve personalization, but even those carry a margin of error. Use this estimate as a directional guide rather than an exact figure.
Should I eat back the calories I burn during exercise?
Whether to eat back exercise calories depends on your goal — weight loss, maintenance, or muscle gain. Most nutrition strategies already factor in a moderate activity level through TDEE estimates, so fully replacing all burned calories may reduce your deficit. Working with a registered dietitian or sports nutritionist can help you set the right calorie target for your specific goals.
