Formula explanation
How this calculator works
Core formula
TDEE = BMR * activity multiplierBasal metabolic rate is estimated with the Mifflin-St Jeor equation, then scaled by your activity level to estimate total daily energy expenditure.
- BMR is the energy your body uses at rest.
- TDEE is the better maintenance target because it includes activity.

FAQ
Key questions answered
What does this resting metabolic rate calculator estimate?
This resting metabolic rate calculator estimates basal calorie burn from the body, activity, or training inputs shown on the page.
How does the resting metabolic rate calculator work?
The calculator applies the formula tied to this page and then highlights the fitness metric that searchers usually care about first, such as calories, protein, pace, or body composition.
Which inputs matter most for a realistic result?
Body size, age, activity level, and training assumptions usually matter most. If those assumptions drift from reality, the result is still directionally helpful but less precise.
Should I treat this fitness result as exact?
No. These equations are best used as planning tools. They help you start with a defensible target, then adjust based on real performance, recovery, and body-composition feedback.
