What is a BMR and TDEE calculator?

A BMR and TDEE calculator is a tool used to estimate your daily calorie needs based on your body data and activity level. BMR represents your basic calorie needs at rest, while TDEE represents your total daily energy expenditure.

What is the difference between BMR and TDEE?

BMR (Basal Metabolic Rate) is the number of calories your body needs to function at rest. TDEE (Total Daily Energy Expenditure) is your BMR multiplied by an activity factor, representing your total daily calorie needs.

How is BMR calculated?

This calculator uses the Mifflin–St Jeor equation, which is one of the most widely accepted formulas for estimating BMR based on age, height, weight, and gender.

How is TDEE calculated?

TDEE is calculated by multiplying your BMR by an activity level factor, such as sedentary, light, moderate, active, or very active.

Can this calculator help with weight loss or weight gain?

Yes. By comparing your daily calorie intake with your TDEE, you can estimate whether you are in a calorie deficit (weight loss), maintenance, or surplus (weight gain).

Is this BMR and TDEE calculator a medical diagnosis?

No. This calculator provides general estimations and is intended for informational purposes only. It should not be considered medical advice.

Is my data stored or sent to a server?

No. All calculations are performed entirely in your browser. No personal data is stored or transmitted.
