How to use the TDEE Calculator
- Select the requested method and measurement system where available.
- Enter measurements using the units shown in each label.
- Select Calculate or press Enter.
- Review the method, source, assumptions, limitations, and visible safety note.
Worked example
An estimated BMR of 1,600 kcal/day multiplied by 1.55 gives an estimated TDEE of 2,480 kcal/day.
Understanding the result
TDEE and maintenance energy are broad planning estimates, not wearable measurements or exact intake prescriptions.
Assumptions
- Body values represent the adult user.
- The selected activity multiplier is representative.
Limitations
- Activity categories are broad.
- The equation is for adults and does not cover pregnancy, breastfeeding, growth, or clinical nutrition.
Sources and method references
- Mifflin–St Jeor resting-energy equation (1990). Population equation; measured resting expenditure can differ.
Frequently asked questions
How is TDEE different from BMR?
The result is an educational estimate based on the selected method and entered assumptions. Individual measurements, needs, and outcomes vary.
Does CalculatorCheck store inputs from the TDEE Calculator?
