Calories Burned Calculator uses the standard MET planning equation with body weight, minutes and session count visible beside the result.
Calories Burned Calculator
Calories Burned Calculator estimates activity energy from body weight, MET value, duration and session count.
Source references
- Mifflin et al. resting metabolic rate equation — BMR equation source
Formula
Calories = MET x 3.5 x body weight kg / 200 x minutes x sessions.
Worked example
80 kg at 6 MET for 45 minutes burns about 378 kcal by the MET equation.
Professional note
Use calories burned as a rough planning number, not a precise food-credit number.
Regional and unit assumptions
Health education estimate using metric inputs. Seek professional advice for medical, eating-disorder, pregnancy, adolescent or clinical needs.
Assumptions and limitations
- MET values are approximate activity averages.
- Fitness, efficiency, terrain and sensors can change real energy use.
- Not medical or training advice.
Methodology & Accuracy
How this calculator is checked
CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.
Formula used
Calories = MET x 3.5 x body weight kg / 200 x minutes x sessions.
Standard or basis
Health education estimate using metric inputs. Seek professional advice for medical, eating-disorder, pregnancy, adolescent or clinical needs.
Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.Master's Tip
Use calories burned as a rough planning number, not a precise food-credit number.

Questions
Is TDEE exact?
No. It estimates average daily energy expenditure. Real expenditure varies by body composition, training, health and tracking accuracy.
What activity factor should I use?
Use a conservative factor first, then adjust after tracking weight and intake over time.
Calculation note
MET calculations make activity comparisons possible by scaling intensity against body weight and duration.
Calories burned needs assumptions beside the result
The calculator keeps the input values, formula trail and limitation note visible so the result can be checked later instead of treated as a magic number.
The printable record is part of the calculator
A useful result is one that can be compared with a statement, plan, workout log, timetable or worksheet after the page is closed.
