About TDEE Calculator
Most people pick a calorie target by guessing, copying a friend, or following a random number from the internet. That usually leads to slow progress, frustration, or eating too little. Our TDEE Calculator is designed to fix that. At TDEEsCalculator.com, we provide a free TDEE calculator with simple explanations to help you estimate your daily calorie needs, understand your maintenance calories, and choose a calorie target that fits your body and fitness goals. Whether you want to lose weight, maintain your current weight, or build muscle, our Total Daily Energy Expenditure (TDEE) calculator helps you make more informed decisions about your daily calorie intake.
Who We Are
TDEE Calculator is an independent educational website dedicated to helping people understand their daily calorie needs. We provide a free TDEE Calculator and easy-to-follow guides about total daily energy expenditure, metabolism, maintenance calories, and healthy weight management. Our goal is simple: to make calorie calculations and nutrition information easier to understand, so you can estimate your daily energy needs and make informed decisions about your fitness goals, whether you want to lose weight, maintain your weight, or build muscle.
Our Mission
Our mission is to help everyone understand their daily calorie needs through a free and easy-to-use TDEE Calculator. We believe people should be able to estimate how many calories their body burns each day without paying for an app, creating an account, or reading complicated science papers. By providing a simple Total Daily Energy Expenditure calculator and clear educational resources, we aim to make it easier to understand maintenance calories, set realistic weight goals, and make informed decisions about healthy weight management.

What Our TDEE Calculator Does
Our calculator is designed to be fast, free and easy to use. In a few seconds it can:
- estimate your BMR from your age, sex, height and weight
- apply an activity multiplier to estimate your TDEE
- show your approximate maintenance calories
- help you see how a calorie deficit or calorie surplus may compare with your maintenance level
- give you a starting point for planning macronutrients such as protein, carbohydrates and fats
You do not need to create an account, and the process takes only a minute.
How We Calculate Your Results
We rely on well-known, published equations that are widely used in nutrition education and research.
Step 1: Estimating BMR
Depending on the calculator you choose, BMR may be estimated with commonly used equations such as:
- Mifflin-St Jeor equation: a popular modern formula based on weight, height, age and sex.
- Revised Harris-Benedict equation: one of the older, widely recognized prediction formulas.
- Katch-McArdle formula: uses lean body mass, which can be useful if you know your body fat percentage.
Our Commitment to Responsible Health Information
Nutrition is personal, and what works for one person may not suit another. We therefore encourage safe, gradual and sustainable habits. We do not promote crash diets, extreme calorie restriction or rapid weight change.
Please remember that our content is for education only and is not medical advice. If you are pregnant, breastfeeding, under 18, living with a medical condition, taking regular medication, or have ever had an eating disorder, speak with a doctor or registered dietitian before changing your diet or exercise routine.

TDEE vs BMR: What Is the Difference?
Many people confuse these two terms. BMR is the energy your body would use if you rested all day. TDEE includes BMR plus digestion and all of your movement. This means your TDEE is always higher than your BMR.
A common mistake is eating at BMR level and calling it a “maintenance” diet. Because BMR leaves out daily activity, eating only that amount can be too low for many people. Our calculator shows both numbers so you can see the difference clearly.
Understanding Your Calorie Goal
Once you know your maintenance calories, you can think about your goal in a simple way:
- Maintain weight: eat close to your TDEE.
- Lose weight gradually: eat a modest calorie deficit below your TDEE. Small, steady deficits are generally easier to follow than extreme ones.
- Build muscle or gain weight: eat a small calorie surplus above your TDEE, combined with regular strength training.
We never encourage aggressive cuts or crash diets. Slow, consistent progress is safer and easier to maintain than quick changes that are hard to keep up. Please read our Medical Disclaimer before making changes to your diet.
Macronutrients Made Simple
Calories tell you how much to eat. Macronutrients describe what that energy is made of:
- Protein: supports muscle repair, helps with fullness and is important when training or eating in a calorie deficit.
- Carbohydrates: the body’s main and most convenient energy source, especially for active people.
- Fats: needed for hormones, absorption of certain vitamins and long-term health.
Your total calorie target and your macro split work together. Our guides explain these basics in plain language so you can plan balanced meals without confusion.
Our Editorial Standards
- Accuracy first: we base our content on published formulas and recognized nutrition concepts.
- Original writing: our guides are written for this website.
- Plain language: we explain technical terms like BMR, TDEE and BmI in simple words.
- Regular updates: we review and improve our pages over time.
- No miracle claims: we do not promote extreme diets or guaranteed results.
How to Get the Most Accurate Result
A few simple habits can make your TDEE estimate more useful:
- Enter honest numbers. Use your current weight and height, not your goal weight.
- Choose your activity level carefully. Think about an average week, not your best week.
- Weigh yourself under similar conditions. Same time of day, similar clothing, ideally a few times a week.
- Look at weekly averages. Daily weight changes from water, salt and digestion are normal.
- Adjust slowly. Change your intake in small steps and give each change a couple of weeks.
- Recalculate when life changes. If your weight, job or training changes, run the TDEE calculator again.
