Calorie Calculator
Calculate daily caloric needs based on age, weight, height, and activity level.
What calorie estimates represent
Calorie calculators use formulas such as Mifflin–St Jeor to estimate baselines from height, weight, age, and activity. These numbers are a planning starting point, not a guarantee of your metabolism, hormone status, or medical conditions. The same food label can be absorbed differently in real life, so use trends over weeks, not a single number.
Use the tool
How to use the output without spiraling
If you are working with a clinician or coach, share the estimate as context. If the tool asks for activity level, be honest, because the multiplier swings the result. If the goal is weight change, small sustainable adjustments and consistency matter more than chasing perfect precision in one TDEE value.
Not medical advice
The numbers are for general information. Any diet change for medical reasons should be supervised by a qualified professional.
