About TDEE
TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns each day, including BMR and physical activity.
BMR (Basal Metabolic Rate) is the calories your body needs at complete rest.
What is TDEE?
TDEE (Total Daily Energy Expenditure) is the total calories your body burns daily, including BMR and physical activity.
Activity Levels
Choose your activity level accurately for the most precise calorie calculation. Be honest about your daily movement.
Weight Goals
Whether you want to lose, maintain, or gain weight, we'll calculate your exact daily calorie needs.
Understanding Calorie Balance
Weight Loss
To lose weight, consume fewer calories than your TDEE. A 500-calorie daily deficit leads to ~0.5kg (1lb) loss per week.
Weight Maintenance
To maintain weight, match your calorie intake to your TDEE. This keeps your weight stable.
Weight Gain
To gain weight (muscle), consume more calories than your TDEE. A 500-calorie surplus leads to ~0.5kg (1lb) gain per week.

TDEE Calculator: How Many Calories You Really Burn Each Day
What is TDEE? (And Why It's the Only Number You Need)
TDEE stands for Total Daily Energy Expenditure - fancy talk for "all the calories you burn in a day." Every breath you take, every step you walk, every time you digest food, even while you sleep - it all adds up to your TDEE.
Here's the simple version: TDEE is the number on the scale that actually matters. Eat more than your TDEE? You gain weight. Eat less? You lose weight. Eat the same? Your weight stays put. It's that straightforward.
TDEE vs. BMR: What's the Difference?
BMR (Basal Metabolic Rate) is what you'd burn if you stayed in bed all day - just staying alive.
TDEE is BMR + everything else - walking, exercise, digestion, fidgeting.
Example: BMR of 1,600 + 400 daily activity = TDEE of 2,000
Why TDEE is Your Weight Management GPS
- Know your TDEE = Know exactly how much to eat
- Stop guessing if you're eating too much or too little
- Adjust with precision when weight loss stalls
The 4 Things That Make Up Your TDEE
BMR
Basal Metabolic Rate (60-75%)
Calories for basic life support: breathing, heartbeat, brain function, cell repair. You burn this even in a coma.
NEAT
Non-Exercise Activity (15-30%)
All movement that's not exercise: walking to the car, fidgeting, standing, chores, typing. This varies wildly between people.
TEF
Thermic Effect of Food (10%)
Calories burned digesting food. Protein burns the most (20-30%), fat burns the least (0-3%).
EAT
Exercise Activity (5-10%)
Intentional exercise: gym workouts, running, sports. The smallest piece of the pie for most people.
The NEAT Secret: Two people with the same job and exercise routine can have TDEE differences of 500-1,000 calories just from NEAT. The person who paces on phone calls, stands at their desk, and fidgets burns way more than the one who sits perfectly still. Small movements add up big time!
Activity Levels: Pick the Right One (Most People Get This Wrong)
This is where most people mess up their TDEE. They pick "moderate" when they're actually "lightly active." Be honest with yourself - it's better to underestimate and adjust up than overestimate and wonder why you're gaining weight.
Sedentary
Desk job, little to no exercise
Lightly Active
Light exercise 1-3x/week or standing job
Moderately Active
Moderate exercise 3-5x/week
Very Active
Hard exercise 6-7x/week or physical job
Super Active
Athlete training twice/day, very physical job
Reality check: Most people pick "moderate" when they're actually "lightly active." If you're not sure, pick the lower option. You can always eat more if you're losing too fast. You can't undo gaining 5 lbs from overestimating.
Your TDEE-Based Calorie Goals
Weight Loss
Never eat below BMR long-term without medical supervision.
Maintenance
Recalculate every 10 lbs - your TDEE changes as your weight changes.
Weight/Muscle Gain
For muscle gain: Pair surplus with progressive overload training.
The 3,500-calorie rule: One pound of fat ≈ 3,500 calories. A 500-calorie daily deficit = about 1 lb lost per week. This is simplified - actual results vary based on body composition, water retention, and metabolic adaptations.
Macronutrients: What to Eat With Your TDEE
Calories are just the first step. What those calories are made of matters for how you feel, perform, and look.
Weight Loss
2.0-2.4g/kg - preserves muscle
Prioritize fiber, complex carbs
Essential for hormones
Maintenance
1.2-1.6g/kg
Primary energy source
0.8-1.0g/kg
Muscle Gain
1.6-2.2g/kg
Fuel for workouts
Hormone support
Sample TDEE & Macro Targets
8 Things That Change Your TDEE (Some You Can Control)
Muscle Mass
+30-50 kcal per kg of muscle. Biggest controllable factor.
Age
-1-2% per decade after 20 (mostly from muscle loss).
Gender
Men average 10-15% higher TDEE due to more muscle.
Body Size
Larger bodies = more calories, even at rest.
Sleep
Poor sleep drops TDEE 5-10% next day + increases hunger.
Temperature
Cold exposure can increase TDEE 5-15% (shivering/NEAT).
Caffeine
+3-5% TDEE for 2-3 hours after consumption.
Thyroid
Hyper: +30-60%, Hypo: -30-50% TDEE.
How to Find Your REAL TDEE (Not Just an Estimate)
Calculators give you a starting point. Here's how to dial in your exact numbers:
The 4-Week Method
- 1Get estimated TDEE from calculator
- 2Eat that many calories daily for 2 weeks
- 3Track weight weekly (same time/conditions)
- 4If weight stable, that's your maintenance
- 5Adjust ±100-200 based on results
When to Recalculate
- Every 10-15 lbs lost or gained
- When your activity level changes significantly
- After 4-6 weeks of plateau
- After pregnancy or major life changes
Pro Tip: Our calculator saves your results. Use the "Compare" feature to see how your TDEE changes as you progress.
TDEE Myths vs. Facts
Myth: Eating small meals boosts metabolism
Meal frequency doesn't significantly affect TDEE. Total calories matter, not timing.
Fact: TDEE drops as you lose weight
Less body mass = less energy needed. Recalculate every 10-15 lbs lost.
Myth: All calories are equal
Protein burns more calories to digest (20-30%) than carbs (5-10%) or fat (0-3%).
Fact: Muscle increases TDEE 24/7
Each pound of muscle burns 6-10 calories daily at rest. Five pounds = 30-50 calories.
Myth: Metabolism crashes at 30
Age-related decline is mostly from muscle loss. Strength training prevents it.
Fact: NEAT is the biggest variable
NEAT can vary by 2,000 calories between sedentary and active people.
Frequently Asked Questions About TDEE
Q:How accurate are TDEE calculators?
A:They're about 85-95% accurate for most people if you're honest about your activity level. The Mifflin-St Jeor equation (what we use) is the most accurate formula. But they're still estimates - your actual TDEE might be 100-200 calories off. That's why tracking your results and adjusting is important.
Q:Should I eat back exercise calories?
A:Only if you're hungry or under-fueled. Most people choose an activity level that already accounts for exercise (like "moderate" if you exercise 3-5x/week). If you track exercise separately, only eat back 50-75% of estimated calories - fitness trackers often overestimate burn by 20-50%.
Q:Why is my TDEE lower than I expected?
A:Most people overestimate their activity level. If you have a desk job and workout 3x/week, you're probably "lightly active" (1.375), not "moderate" (1.55). Also, smaller bodies, less muscle, and being older all lower TDEE. Use the lower multiplier and adjust up if needed.
Q:How do I find my TDEE without a calculator?
A:Track everything you eat for 2 weeks while weighing yourself daily. If your weight is stable, your average daily calories = your TDEE. If you gained weight, subtract 3,500 calories per pound gained and divide by 14 days. If you lost weight, add that amount. This is the most accurate method.
Q:Does TDEE change during menstrual cycle?
A:Yes, slightly. Some women burn 5-10% more calories during the luteal phase (week before period). You might notice more hunger then - it's normal. Don't stress about it, just listen to your body.
Q:Should I use the same TDEE every day?
A:Your TDEE varies day-to-day based on activity, but you don't need to track it daily. Use your average weekly TDEE as a target. Some people like "calorie cycling" - eating more on workout days and less on rest days - but it's not necessary for results.
Q:Can I increase my TDEE?
A:Yes! Best ways: (1) Build muscle - each pound burns 6-10 extra calories daily (2) Increase NEAT - walk more, stand, fidget (3) Eat enough protein - higher TEF (4) Get good sleep - prevents metabolic slowdown (5) HIIT cardio - can elevate metabolism for hours after.
Q:What's the difference between TDEE and maintenance calories?
A:They're the same thing! Your maintenance calories = your TDEE. It's the number where your weight stays stable. From there, subtract for weight loss, add for weight gain.
