TDEE Calculator

Enter your age, height, weight, and activity level, and this calculator returns your Basal Metabolic Rate — the calories your body burns at rest — plus your Total Daily Energy Expenditure adjusted for how active you actually are. From there it breaks out three practical targets: a calorie deficit for fat loss, a maintenance figure, and a surplus for building muscle.

It's a useful starting point whether you're questioning why the number on the scale isn't moving or just trying to eat with more intention. The math is based on the Mifflin-St Jeor equation, one of the more reliable formulas in health & fitness tools. If you want to put those numbers to work right away, Calorie Counter lets you log meals and track daily intake against whatever target you land on here.

No account needed — just fill in the four fields and your results appear instantly, making it worth bookmarking for a quick recalculation any time your weight or routine changes.
