TDEE Calculator is the fastest and most accurate free tool to find out exactly how many calories your body burns every single day — based on your age, weight, height, and activity level. Whether your goal is weight loss, muscle gain, or simply maintaining a healthy lifestyle, knowing your Total Daily Energy Expenditure (TDEE) is the foundation of every successful nutrition plan.

Without knowing your TDEE, you are essentially guessing how much to eat — and guessing leads to frustration, plateaus, and wasted effort. Our TDEE Calculator removes all the guesswork and gives you a precise, science-backed calorie number in under 30 seconds.

What Is a TDEE Calculator?

A TDEE Calculator is a digital tool that estimates the total number of calories your body uses in a single day. TDEE stands for Total Daily Energy Expenditure — a number that accounts for everything your body does, from breathing and digesting food to walking, exercising, and even sleeping.

Unlike a basic calorie counter, a TDEE Calculator factors in your unique body metrics and daily activity level to give you a personalised calorie target — not a generic number copied from a government chart.

According to research published on PubMed, the Mifflin-St Jeor equation used in our calculator is the most scientifically validated formula for estimating daily energy needs in adults.

How Does the TDEE Calculator Work?

Our TDEE Calculator uses a two-step process to calculate your daily calorie needs:

Step 1 — Calculate your BMR (Basal Metabolic Rate) Your BMR is the number of calories your body burns at complete rest — just to keep your heart beating, lungs breathing, and organs functioning. We calculate this using the Mifflin-St Jeor equation, which is considered the gold standard by nutrition scientists worldwide.

Step 2 — Multiply by Your Activity Level Your BMR is then multiplied by an activity factor that reflects how much you move throughout the day. This gives you your final TDEE — your true daily calorie burn.
