Calorie Burn by Activity Calculator – Complete Guide
Knowing how many calories you burn with different activities can help you plan workouts, balance food intake and set realistic weight management goals. But exercise machines, fitness trackers and online charts often give slightly different numbers, which can be confusing.
The Calorie Burn by Activity Calculator on MyTimeCalculator uses standard MET values and your body weight to estimate calories burned for a wide range of activities. You can compare exercises, log multiple sessions across the day and see how your choices add up to real energy expenditure.
1. What Is a MET and Why It Matters
MET stands for Metabolic Equivalent of Task. It is a simple way to describe how much energy an activity uses compared with resting. By definition:
- 1 MET ≈ energy cost of sitting quietly.
- Activities with 3–6 METs are considered moderate intensity.
- Activities with more than 6 METs are considered vigorous intensity.
For example, slow walking might be around 2.5–3 METs, brisk walking around 4–5 METs, and running at a steady pace may range from 8 METs to 12 METs or more depending on speed. The higher the MET value, the more calories you burn per minute at a given body weight.
2. How the Calorie Burn Formula Works
The calculator uses a standard formula that combines MET, body weight and time:
Once calories per minute are known, total calories burned in a session is:
This approach is widely used in exercise physiology and is the basis for many charts and device estimates. The main inputs you control are:
- Your body weight.
- The activity (which sets the MET value).
- The duration of the activity.
3. How to Use the Calorie Burn by Activity Calculator
- Enter your weight and select the unit. You can work in kilograms or pounds. The calculator automatically converts pounds to kilograms internally.
- Choose an activity. Pick the option that most closely matches what you are doing, such as walking, running, cycling, swimming, strength training, sports or household tasks.
- Set the duration in minutes. Use the actual time you spend actively doing the movement, not including long breaks.
- Optional: Override with a custom MET. If you know a specific MET value from a research source, you can type it in the custom MET field. Otherwise, leave it blank to use the preset.
- Click “Calculate Calories Burned & Add to Log”. The calculator estimates calories burned for that session and adds it to your daily activity log.
- Repeat for other activities. Add as many different entries as you like during the day to see how your total calorie burn from movement accumulates.
4. Understanding the Results
The results section gives you several useful numbers:
- Calories burned (session): The estimated energy expenditure for the specific activity and duration you entered.
- Calories per hour: A normalized rate that lets you compare how “expensive” different activities are if you did each one for the same amount of time.
- MET value used: The MET from the preset database or your custom MET override.
- Daily total (all logged activities): The running sum of calories burned from every activity you have added to the log during the session.
- Equivalent brisk walking: A rough comparison showing how many minutes of typical brisk walking would burn around the same number of calories as your logged activities.
The activity log table also shows each individual entry, including the activity name, duration, MET and calories burned. This makes it easy to spot which movements contribute the most to your daily energy expenditure.
5. Typical MET Ranges for Common Activities
Different activities have different MET ranges depending on intensity. The calculator includes a variety of presets such as:
- Walking: From easy strolling to brisk walking at 4–5 METs.
- Running and jogging: From easy jogging to faster running, often 7–12+ METs.
- Cycling: Leisure cycling, moderate commuting or vigorous spinning classes.
- Gym and fitness: Strength training, circuit training, HIIT-style workouts.
- Sports: Basketball, football/soccer, tennis, badminton and similar games.
- Swimming: Easy laps, moderate front crawl, vigorous training sets.
- Home and daily life: Housework, yard work, carrying loads and more.
If you are not sure which exact option to choose, it is usually fine to select the closest match by intensity (easy, moderate or vigorous). The goal is a reasonable estimate, not a perfect measurement.
6. Using Calorie Burn Estimates for Weight Management
In simple terms, weight change over time is strongly influenced by your overall energy balance:
The calculator helps you understand the “calories burned” sideated to physical activity. To get a fuller picture, you can combine it with:
- Your estimated basal metabolic rate (BMR).
- Your total daily energy expenditure (TDEE).
- Your typical food intake over a day or week.
Rather than chasing perfect accuracy, it is more helpful to look at trends. If you consistently add more movement and keep food intake steady, a modest calorie deficit can accumulate over weeks into meaningful changes. Likewise, understanding how much exercise is needed to offset certain treats can support more deliberate choices.
7. Limitations and Practical Tips
Any calorie burn calculator based on METs and body weight has limitations:
- Individual differences: Fitness level, body composition and genetics all influence how efficiently your body uses energy.
- Intensity variation: Two people “jogging” may be running at very different speeds and effort levels, even if they pick the same preset.
- Short bursts: Very short or stop-and-go activities are harder to estimate precisely.
To get the most value from the tool:
- Use realistic durations that match actual time spent moving.
- Update your body weight periodically if it changes significantly.
- Look at averages across several days instead of a single workout.
- Combine these estimates with how you feel, your performance and long-term trends in weight or measurements.

Frequently Asked Questions
Quick answers to common questions MET values, calories burned estimates and how to use this calculator in everyday training and weight management.
The calculator uses standard MET values and your body weight to estimate energy expenditure. This method is widely used and gives reasonable averages for many people, but it cannot capture individual differences in fitness, technique or metabolism. The numbers are best treated as useful estimates rather than exact measurements. For precise assessments, laboratory testing with gas analysis is required, which is not practical for everyday use.
If your exact activity is not available, choose the closest match by movement pattern and intensity level. For example, if you are hiking uphill with a backpack, you might select a vigorous walking or hiking preset. You can also use the custom MET field if you know a more specific MET value from a trustworthy reference source. Either way, the goal is to get a realistic ballpark rather than a perfect match.
No, the calculator does not use heart rate, VO2max or fitness level directly. Ities on MET values, which are average estimates for a typical adult performing the activity at a given intensity. Fitter individuals may burn slightly fewer calories at the same pace because their bodies can be more efficient, while those less accustomed to the activity may burn slightly more. Over time, you can adjust your expectations based on experience and other measurements such as body weight trends.
Yes, the calculator can be a helpful part of planning. By estimating calories burned from activity, you can combine these values with your estimated daily calorie needs and typical food intake to design a modest calorie deficit. However, any weight loss plan should consider your overall health, sleep, stress and nutrition quality, not just exercise calories. If you have medical conditions or specific goals, it is wise to discuss your plans with a qualified health professional or registered dietitian.
Different devices and apps may use slightly different formulas, MET values and assumptions your body weight or fitness level. Some treadmills and bikes assume a default weight if you do not enter your own. Others may blend heart rate data with speed and incline. The important point is to pick one method, use it consistently and focus on trends over time. This calculator gives transparent, MET-based estimates you can compare across activities on a level playing field.
No. The log is stored only in your current browser session. It resets when you refresh, close the tab or clear the log manually. If you want to track activity over longer periods, you can copy the results into a spreadsheet, notebook or dedicated fitness app after each day and use the calculator as a quick, flexible estimating tool.
