TDEE Calculator is a free online tool that helps you estimate how many calories your body burns each day. Our goal is simple: give you a clear, accurate starting number for your calorie intake, without sign-ups, apps or paywalls.
What we do
Your Total Daily Energy Expenditure (TDEE) is the total number of calories you burn in a day, including your basal metabolic rate (BMR), daily activity and exercise. Knowing this number makes it much easier to plan for weight loss, maintenance or muscle gain.
- We calculate BMR with the Mifflin-St Jeor equation, which research has found to be among the most accurate for most adults.
- We apply standard activity multipliers to estimate your TDEE.
- We show calorie targets for losing, maintaining and gaining weight.
How we create our content
Our guides explain the science behind calories, metabolism and activity in plain language. We base them on published research and widely accepted nutrition guidelines, and we review them regularly to keep them accurate.
