How to Use TDEE Calculator

Enter your age, gender, height, weight, and activity level. The calculator uses the Mifflin-St Jeor equation to estimate your Basal Metabolic Rate (BMR), then multiplies it by your activity factor to calculate your Total Daily Energy Expenditure (TDEE). This tells you roughly how many calories you burn per day, which is the starting point for any weight management or fitness goal.

Frequently Asked Questions

What is TDEE?+
TDEE stands for Total Daily Energy Expenditure — the total number of calories your body burns in a day, including your basal metabolic rate (BMR), physical activity, and the thermic effect of food.
How accurate is this calculator?+
TDEE calculators provide a solid estimate (within 10-15% for most people), but individual variation exists. Use the result as a starting point and adjust based on real-world results over 2-4 weeks.
Should I eat at my TDEE to lose weight?+
To lose weight, eat 300-500 calories below your TDEE. To gain weight, eat 300-500 above it. Eating exactly at your TDEE should maintain your current weight.
Which formula do you use?+
We use the Mifflin-St Jeor equation, which research shows is the most accurate for estimating BMR in most populations.
