Your Total Daily Energy Expenditure is the number you need before making any informed decision about food and weight. Enter your details below and we’ll calculate it using the Mifflin-St Jeor equation — the most accurate formula available for most people.
Your Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a day — including everything from breathing to exercise. It’s the number you need to know before making any informed decisions about food and weight.

What is TDEE?
Total Daily Energy Expenditure is the total calories you burn each day. It combines your Basal Metabolic Rate (what you burn at rest) with calories burned through activity.
What is BMR?
Basal Metabolic Rate is the minimum calories your body needs to function at complete rest — breathing, circulation, cell repair. It’s roughly 60-70% of your TDEE.
Which formula do we use?
The Mifflin-St Jeor equation, published in 1990. Studies consistently show it’s the most accurate formula for estimating BMR in most adults — more reliable than Harris-Benedict.
How accurate is this?
TDEE calculators are estimates — individual metabolism varies. Treat this as a starting point, track your actual results for 2-3 weeks, and adjust from there. Your body will tell you the truth.
