The Calorie Calculator estimates your Total Daily Energy Expenditure (TDEE) — the total number of calories your body burns in a day based on your age, weight, height and activity level. This is your starting point for weight loss, gain or maintenance.
Frequently Asked Questions
How many calories should I eat per day?
It varies by person. The calculator uses the Mifflin-St Jeor equation — the most accurate formula for most people. Results typically range from 1,500 to 3,000 calories depending on size and activity.
What is TDEE?
Total Daily Energy Expenditure — all calories your body burns including basic functions (BMR), digestion, and physical activity.
How many calories do I need to lose weight?
A deficit of 500 calories per day leads to roughly 0.5kg (1 lb) of weight loss per week. Avoid going below 1,200 calories (women) or 1,500 calories (men) without medical supervision.
What is BMR?
Basal Metabolic Rate — the calories your body burns at complete rest just to keep you alive. It accounts for about 60–70% of your TDEE.
