Calorie Calculator
Estimate how many calories you burn in a day. Enter your sex, age, height, weight and activity level to see your BMR, your maintenance calories (TDEE), and target intakes for losing or gaining weight.
Estimates from the Mifflin-St Jeor equation. For general guidance only, not medical advice.
Frequently asked questions
How are my daily calories calculated?+
We estimate your basal metabolic rate (BMR) with the Mifflin-St Jeor equation, then multiply by an activity factor to get your total daily energy expenditure (TDEE) — the calories you burn in a typical day.
How many calories should I eat to lose weight?+
A deficit of about 500 calories a day is a common target for losing roughly 0.5 kg (1 lb) per week. The calculator shows mild and standard weight-loss targets alongside your maintenance level.
Is this medical advice?+
No. These are estimates for general guidance only. Calorie needs vary by individual — consult a doctor or dietitian before starting a weight programme.
