TDEE Calculator
This calculator can be used to estimate your Total Daily Energy Expenditure (TDEE). TDEE is the total number of calories you burn each day, including your basal metabolic rate and physical activity.

Total Daily Energy Expenditure
| Basal Metabolic Rate (BMR) | -- cal |
Daily Calorie Needs by Activity Level
| Sedentary: little or no exercise | -- cal |
| Light: exercise 1-3 times/week | -- cal |
| Moderate: exercise 4-5 times/week | -- cal |
| Active: daily exercise or intense 3-4 times/week | -- cal |
| Very Active: intense exercise 6-7 times/week | -- cal |
| Extra Active: very intense daily exercise | -- cal |
Note: Exercise: 15-30 minutes of elevated heart rate activity. Intense exercise: 45-120 minutes of elevated heart rate activity. Very intense exercise: 2+ hours of elevated heart rate activity.
• Exercise: 15-30 minutes of elevated heart rate activity.
• Intense exercise: 45-120 minutes of elevated heart rate activity.
• Very intense exercise: 2+ hours of elevated heart rate activity.
Most people think that their metabolism is a mystery, do you? They evaluate “calories in versus calories out” but it’s not something done like a school maths. You when you chase fitness only eat what you think is a “healthy” amount, but on scale you see no difference.
Think of your TDEE as your body’s “daily budget.” Just like a bank account tells you how much you can spend based on what’s coming in, your TDEE tells you exactly how much energy your body burns in a 24-hour window. When you know this number, the guesswork finally stops. You use the TDEE calculator below to find your unique number and finally understand what your body actually needs to thrive.
What is TDEE? (The “Fuel Gauge” Explanation)
In the simplest terms, TDEE is the total number of calories you burn every single day. It isn’t just about the hour you spend sweating in the gym; it’s the sum of every little thing your body does, from pumping blood to your heart while you’re dreaming to fidgeting with your pen during a long meeting. Most of us make the mistake of thinking our metabolism is just one big engine. In reality, your Total Daily Energy Expenditure is more like a business with four distinct “departments”:- Basal Metabolic Rate (BMR): This is your “cost of living.” It’s the amount of energy your body uses just to keep the lights on and your organs humming while you lie perfectly still. Even if you stayed in bed watching movies all day, your BMR would still account for about 60-70% of your total burn.
- Thermic Effect of Food (TEF): It is that your body burns caloric fuel to digest the chunks of food as well. So some foods would be digested easily other will be tough.
- Thermic Effect of Activity (TEA): It is when the energy is produced out of activity.
- NEAT (Non-Exercise Activity Thermogenesis): This is the unofficial exercise that you perform, not a heavy workout or cardio but just moving maybe to the gate maybe to pick a child or things like this.
Why the Scale Doesn’t Tell the Whole Story
We often get caught up in our total weight, but as you’ve seen on our body fat calculator page, the “quality” of that weight matters so much more than the number. Your body composition—the balance of muscle versus fat—is a massive driver of your TDEE.The Science: How the Calculator Figures Out Your Budget
Our tool doesn’t just guess or use a random number. It uses established nutritional science, specifically the Mifflin-St Jeor equation, to estimate your daily burn. We take your age, gender, height, and weight and combine them with your activity level to find your “maintenance” calories.The Activity Level Multipliers:
The biggest “variable” in your TDEE is how much you actually move. We use standard physical activity levels (PAL) to adjust your BMR and give you a realistic target:- Sedentary: Little to no exercise (The classic desk-job life).
- Lightly Active: Light exercise or sports 1-3 days a week.
- Moderately Active: Moderate exercise or sports 3-5 days a week.
- Very Active: Hard exercise or sports 6-7 days a week.
- Extra Active: Very hard exercise, a physically demanding job, or training twice a day.
TDEE and Your Goals: Finding Your “Why”
Once you have your TDEE number, you have the “anchor” for whatever goal you’re chasing. It’s not about restriction; it’s about having a strategy that actually works.- For Weight Loss: You want to create a “modest” deficit. Usually, eating about 500 calories below your TDEE is the sweet spot for losing body fat without losing your mind (or your hard-earned muscle).
- For Muscle Gain: You need a “surplus.” To build new muscle mass, your body needs extra energy and the right macronutrients to fuel the construction work.
- For Maintenance: This is the “lifestyle” zone. If you love where you are and just want to feel energetic and strong, you eat at your TDEE level.
Working With Your Type: The Metabolic Connection
Your body type (or somatotype) plays a huge role in how “flexible” your TDEE is in the real world:- Ectomorphs: You often have a naturally high resting metabolic rate. Your body is like a sports car—it burns through fuel incredibly quickly. You might find your TDEE is surprisingly high even when you aren’t doing a ton of exercise.
- Endomorphs: You have a “thrifty” metabolism. Your body is incredibly efficient at storing energy for later. Knowing your TDEE is vital because your “maintenance” level might be a little lower than a generic chart would suggest.
- Mesomorphs: You tend to have a very “responsive” metabolism. Your body uses energy efficiently and responds quickly whenever you change your activity level or your calorie intake.
5 Things That Can Shift Your TDEE (The “Wiggle” Room)
Your TDEE isn’t a fixed number carved in stone. It breathes and changes just like you do. Here is what can cause your daily budget to shift:- Sleep Quality: When you’re sleep-deprived, your hunger hormones go haywire, and your resting metabolic rate can actually dip because your body is trying to “save” energy to get you through the day.
- Stress Levels: High stress leads to high cortisol. While cortisol itself doesn’t stop you from burning calories, it can make your body more likely to hold onto visceral fat and can lower your NEAT because you’re just too exhausted to move.
- Ambient Temperature: Believe it or not, your body burns more energy simply trying to keep you warm in the winter or cool in the summer heat.
- Sarcopenia (Aging): As we get older, we naturally lose some muscle mass. Since muscle drives TDEE, our “budget” tends to shrink as we age—unless we’re proactive about strength training.
- Diet History: If you’ve spent years in extreme calorie deficits, your body may have undergone “metabolic adaptation,” becoming a bit too efficient at surviving on very little.
