tool.calories-burned-total Calculator
Estimates total daily caloric expenditure (TDEE) from basal metabolic rate and activity level, and calculates calories burned in a specific exercise session. TDEE is the starting point for both fat loss (deficit) and muscle gain (surplus) nutrition planning.
Inputs
Bmr
Calories burned at complete rest just to keep organs functioning — roughly 60–70% of total daily expenditure.
Activity Factor
A multiplier applied in the calculation.
Exercise Kcal
Reference formula or conversion factor shown for context.
Days
Reference formula or conversion factor shown for context.
Results
TDEE (kcal/day)
Reference formula or conversion factor shown for context.
with exercise (kcal/day)
Reference formula or conversion factor shown for context.
weekly total (kcal)
The combined total across all inputs and components.
BMR
Reference formula or conversion factor shown for context.
activity factor
Rate of radioactive decay events per second (becquerels or curies). Decreases exponentially with time.
