BMR / TDEE Calculator
Estimate your Basal Metabolic Rate and Total Daily Energy Expenditure (daily calorie needs).
Get personalized daily calorie targets for maintenance, loss, or gain.
Daily calorie target based on BMR (Mifflin-St Jeor) and activity. Choose maintain, lose, or gain for a suggested intake.
TDEE (maintenance): 2556 cal/day
Suggested intake (Maintain): 2556 cal/day
A daily calorie intake calculator gives you a target number of calories per day based on your BMR and activity level. Maintenance intake matches your TDEE; to lose weight, a common approach is to eat about 500 calories less per day (roughly 0.5 kg per week); to gain, eat about 300 more. This tool uses the Mifflin-St Jeor equation and lets you choose a goal (maintain, lose, gain) for a suggested intake. It is for education only—individual needs vary; consult a dietitian for a personalized plan.
