Calories Burned Calculator: estimate activity cost
Reviewed on: 29 August, 2026
MET values compare activity energy across body weight and duration, but are not precise personal readings.
How to use the result
Choose the closest activity and compare durations without treating the output as exact food credit.
How to interpret it
Repeat for different durations and pair it with performance and recovery.
Compare realistic scenarios
Wearables, terrain, pauses, and fitness change real expenditure.
Important context
Use this estimate as context and consult a qualified professional when a health decision matters.
What these items mean
The values and formats used by this tool have a practical meaning beyond the result. This short guide explains what they are, what they are used for, and where they came from.
Health measurements and dates
Inputs such as height, weight, age, heart rate, activity, cycle dates, and pregnancy dates are measurements or estimates used to calculate a reference value. They help with education, planning, and conversations with a qualified professional; they do not diagnose or replace medical advice.
Many formulas were developed by researchers and later adopted as population-level references by health organizations. A reference range is not a personal diagnosis, and individual context matters.
Authoritative resources
For activity and training context, consult WHO’s physical-activity guidance and the CDC’s physical-activity resources.
