How Calorie Calculator works
Daily calorie needs are estimated from the inputs and activity assumptions selected in the calculator. Actual energy needs vary between individuals and over time.
Calculate daily calorie needs and macronutrient splits (Protein, Carbs, Fat) for weight loss, maintenance, or muscle building.

Answers about how the tool works, its limitations, and how your information is handled.
To lose about 0.5 kg (1 lb) per week, aim for a daily deficit of approximately 500 calories below your Total Daily Energy Expenditure (TDEE).
Macros are split using a balanced ratio: 30% Protein (4 kcal/g), 40% Carbohydrates (4 kcal/g), and 30% Fat (9 kcal/g).
TDEE is the total number of calories your body burns in a day, including your basal metabolism plus physical activity and exercise.
No. The result is an informational estimate based on the inputs supported by the calculator. It does not replace advice, diagnosis or treatment from a qualified healthcare professional.
