About the TDEE Calculator
TDEE estimates the calories you burn in a day, combining your resting metabolism (BMR) with an activity factor. It's the baseline for maintaining weight — a general estimate, not medical advice.
How it’s calculated
TDEE = BMR (Mifflin–St Jeor) × an activity multiplier from 1.2 (sedentary) to 1.9 (very active).
Example calculation
A BMR of about 1,699 at a moderate activity level (×1.55) gives a TDEE near 2,633 calories per day.
Frequently asked questions
How do I pick an activity level?
Match it to a typical week — most people who exercise a few times a week fall in the 'lightly' to 'moderately' active range. When unsure, choose the lower level and adjust based on real results.
Will eating my TDEE keep my weight stable?
Roughly — it's an estimate. Track your weight over a few weeks and adjust intake up or down if the trend isn't what you expect.
