About the Calories Burned Calculator
What is the Calories Burned Calculator?
A calories burned calculator uses the metabolic equivalent (MET) of an activity to estimate how many calories you burn in a session.
Why use this calculator?
Understanding exercise energy expenditure makes goals concrete: a session\u2019s hard work gets translated into numbers you can compare with your diet.
How to use it
- Enter your weight.
- Choose the activity closest to your session.
- Enter the duration in minutes.
- Read your estimated burn and the comparison table.
Formula
Calories = MET × 3.5 × weight(kg) ÷ 200 × minutes.
Estimates are generalized; intensity, terrain and your efficiency change the actual burn.
Frequently Asked Questions
Why is my tracker so different from this?
Watches estimate from heart rate and movement algorithms, which often overstate. Use this steady formula for a more conservative baseline.
Should I eat back exercise calories?
Most people should not count on them. The formula above is a guide, not a license to indulge.
Is this a medical diagnosis?
No. This tool provides general wellness information only. It is not a substitute for evaluation by a qualified healthcare professional.
Why do results differ from my doctor's measurements?
Clinical measurements use calibrated equipment and professional technique. Home estimates rely on formulas and self-reported values, so small differences are normal.
How often should I recalculate?
Recheck after meaningful changes such as weight gain or loss, a new workout routine, or every few months to track trends over time.
Do these formulas apply to everyone?
Most population formulas are less accurate for athletes, pregnant people, very young children and the elderly. Use them as a general guide.
Is this calculator free to use?
Yes. Every calculator on this site is completely free, with no hidden fees, no subscriptions and no limits on how many times you can use it.
How accurate are the results?
We use standard, widely accepted formulas and calculate in your browser using double-precision arithmetic. Results are rounded for readability, so treat them as reliable estimates rather than a guarantee. Real-world factors can vary the true figure.
