Calculate your daily calorie needs including BMR and TDEE. Enter age, sex, weight, height, and activity level to get personalised maintenance and goal-based calorie targets.
Open Calorie Calculator → free, no sign-inKnowing your daily calorie needs properly — accounting for your age, weight, height, sex, and how active you actually are — requires two calculations: your Basal Metabolic Rate (the energy you'd burn doing nothing) and your Total Daily Energy Expenditure (what you actually need each day). The Calorie Calculator handles both, with multiple activity levels and goal options, and presents the results in a clear, readable breakdown.
Anyone working on weight management — whether trying to lose, maintain, or gain — who wants accurate targets rather than a generic 2,000-calorie estimate. Useful for athletes fuelling training, coaches setting client targets, or anyone taking a data-driven approach to nutrition.

What is TDEE?
Total Daily Energy Expenditure — the total number of calories you burn in a day, including activity. This is your maintenance calorie level.
What is BMR?
Basal Metabolic Rate — the number of calories your body needs to function at rest. Think of it as the minimum calorie floor.
How much should I eat to lose weight?
A deficit of 500 calories per day below TDEE typically leads to approximately 0.5kg (1lb) of fat loss per week.
Why do the two formulas give different results?
Mifflin-St Jeor and Harris-Benedict use slightly different coefficients. Mifflin-St Jeor is generally considered more accurate for most people.
