Quick start
- Open the Calories Burned Calculator.
- Choose the activity description that matches pace and effort, not just the broad activity name. Moderate level walking at 2.8-3.4 mph is 3.8 MET; brisk level walking at 3.5-3.9 mph is 4.8 MET in the 2024 Adult Compendium.
- Use the first example, "Brisk level walk: 4.8 MET, 70 kg, 45 active min", if you want to see a filled-out calculation before entering your own values.
- Calculate, read the formula line, then copy the result only after the units and assumptions look right.
Best uses
Start here if one of these sounds like your job. The examples below show which inputs matter most.
- Estimate total session calories for common exercise, sport, home, and garden activities.
- Compare total session calories with active calories above the 1-MET resting baseline.
- Use body weight in kilograms or pounds and a current 2024 Compendium activity value.
- Enter a custom MET when a closer activity description comes from an appropriate Compendium table.
What this calculator is for
The Calories Burned Calculator estimates activity energy from a 2024 Adult Compendium preset or custom MET, body weight in kilograms or pounds, and active time. It is best for transparent comparisons, not measuring exact metabolism.
Use it when you want to: Estimate total session calories for common exercise, sport, home, and garden activities. Compare total session calories with active calories above the 1-MET resting baseline.
Calories burned formula: total session versus active calories
Total session calories = MET x 3.5 x body weight in kg / 200 x active minutes. This is the gross estimate used as the main calculator answer.
Active calories above rest use MET minus 1 in the same equation. The subtraction is a transparent derived comparison because CDC and the Adult Compendium define 1 MET as the resting baseline. It is useful when a watch reports active calories rather than total session calories.
- Pounds to kilograms: pounds x 0.45359237.
- CDC absolute intensity: under 3 MET is light, 3 to 5.9 is moderate, and 6 or more is vigorous.
- Count active minutes, not the full clock time when long rest breaks were part of the session.
What to enter
Good answers start with clean inputs. Before calculating, check the labels, units, and dates so the tool is solving the same problem you actually have.
- Choose the activity description that matches pace and effort, not just the broad activity name. Moderate level walking at 2.8-3.4 mph is 3.8 MET; brisk level walking at 3.5-3.9 mph is 4.8 MET in the 2024 Adult Compendium.
- Enter body weight, choose kilograms or pounds, and enter active minutes. The calculator converts pounds to kilograms before using the formula.
- Use Custom MET only when an appropriate Compendium table or qualified source gives a closer value. Keep custom values from 1 to 25.
Example walkthrough
Try the calculator example: Brisk level walk: 4.8 MET, 70 kg, 45 active min. The example result is About 265 kcal total session; about 209 kcal active above rest.
- For a brisk level walk at 4.8 MET, 70 kg, and 45 active minutes: 4.8 x 3.5 x 70 / 200 x 45 = 264.6, which rounds to 265 total session kcal.
- For active calories above rest, subtract the 1-MET baseline first: 3.8 x 3.5 x 70 / 200 x 45 = 209.475, which rounds to 209 active kcal.
- For 154 lb, the calculator first converts weight to about 69.85 kg. At 3.3 MET for 60 minutes of general house cleaning, the result is about 242 total kcal and 169 active kcal above rest.
Formula and steps
In plain language: Total session calories = MET x 3.5 x body weight in kg / 200 x minutes. Active calories above rest use the same equation with MET minus 1 because 1 MET represents the resting baseline. Pounds are converted to kilograms first. Read the result together with the notes on the page, because health and fitness numbers often need personal context.
Read the formula note when you need to understand where the number came from, especially before comparing results over time.
How to read the answer
Total session calories and active calories above rest answer different questions. Neither is a lab measurement, food target, medical exercise prescription, or promise of exact energy balance.
- The large answer is total session calories, including the resting-energy portion for the same minutes.
- Active calories above rest remove the 1-MET baseline. Compare this line with a wearable only when the device also labels its result as active calories.
- The CDC intensity band describes absolute MET intensity. Relative effort can feel different depending on fitness, age, disability, heat, terrain, illness, and medication.
Common mistakes to avoid
Most bad results come from a small input mistake or from using a rough estimate for a decision it cannot safely answer.
- Do not call 3.8 MET brisk level walking when the current adult table uses 4.8 MET for 3.5-3.9 mph brisk walking.
- Do not enter pounds while kilograms is selected or add a second manual conversion after choosing pounds.
- Do not count long rest breaks as active minutes or pick a higher MET because the workout felt hard.
- Do not compare total session calories with active calories from a watch as if the definitions match.
- Do not use exercise calories as automatic food credit, medical nutrition advice, or an exact weight-change prediction.
What to try next
A related health tool can help check the same topic from another angle, but one number should not replace proper care.
- Use Pace Calculator for running or walking pace.
- Use Target Heart Rate Calculator for a separate exercise-intensity estimate.
- Use Calorie Calculator only for a separate daily-energy estimate; do not add exercise calories twice if its activity factor already includes normal workouts.

FAQ in plain language
When should I use the Calories Burned Calculator?
Use it for simple educational checks, trend tracking, or planning tasks like these: Estimate total session calories for common exercise, sport, home, and garden activities. Compare total session calories with active calories above the 1-MET resting baseline. It can help you understand a number, but it cannot explain your whole health situation.
What do the main Calories Burned Calculator inputs mean?
Choose a 2024 Adult Compendium activity or enter a custom MET from 1 to 25, then enter body weight in kilograms or pounds and active minutes. Match the description closely: moderate walking at 2.8-3.4 mph is 3.8 MET, while brisk walking at 3.5-3.9 mph is 4.8 MET.
What is the Calories Burned Calculator doing with my inputs?
In plain language: Total session calories = MET x 3.5 x body weight in kg / 200 x minutes. Active calories above rest use the same equation with MET minus 1 because 1 MET represents the resting baseline. Pounds are converted to kilograms first. Read the result together with the notes on the page, because health and fitness numbers often need personal context.
How should I read the Calories Burned Calculator result?
Read total session calories as the gross estimate, including the energy your body would have used at rest during those minutes. Active calories above rest subtract a 1-MET baseline. Both are rough activity estimates, not a lab measurement, wearable calibration, diet permission, injury advice, or exact energy-balance number.
What MET values are available in this calories burned calculator?
The activity list includes 20 examples from the 2024 Adult Compendium, including walking by pace, hiking, cycling, weight training, yoga, jogging, running, swimming, cleaning, gardening, soccer, and basketball. Use Custom MET when the Compendium has a closer description for your activity.
What is the difference between total and active calories?
Total session calories use the full MET value and include the resting energy your body would use during the same minutes. Active calories above rest subtract a 1-MET baseline. A watch or exercise machine may show either definition, so check its label before comparing numbers.
Is MET x 3.5 x body weight / 200 a CDC calorie formula?
The CDC explains MET intensity, including 1 MET at rest, 3 to 5.9 MET as moderate, and 6 or more as vigorous. Its cited intensity page does not publish this exact personal calorie equation. This calculator uses the common MET energy estimate and activity values from the 2024 Adult Compendium instead of calling it a CDC calorie formula.
