TDEE & Macro Calculator
If you want to lose fat, gain muscle, or maintain your current weight, knowing how much you should eat every day is essential. But it’s not just about calories — it’s also about getting the right balance of macronutrients (protein, carbohydrates, and fats) to fuel your body effectively.
That’s where the TDEE Macro Calculator comes in.
This easy-to-use tool calculates your Total Daily Energy Expenditure (TDEE) and then gives you a custom macronutrient breakdown based on your fitness goal. It takes into account your age, gender, weight, height, activity level, and goal (maintain, lose, or gain weight) to give you personalized nutrition numbers in seconds.
⚡ What is TDEE?
TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns in a day, including all physical activities and normal bodily functions.
It’s calculated using your Basal Metabolic Rate (BMR) and an activity multiplier based on your lifestyle.
Formula:TDEE = BMR × Activity Level
Knowing your TDEE helps you set a calorie target:
- To maintain weight: Eat around your TDEE
- To lose weight: Eat 10–20% fewer calories than your TDEE
- To gain muscle: Eat 10–20% more calories than your TDEE
🍗 What are Macronutrients?
Macronutrients (macros) are the nutrients your body needs in large amounts:
- Protein – builds and repairs muscles
- Carbohydrates – your main source of energy
- Fats – essential for hormones and brain function
Each macro contributes calories:
- 1 gram protein = 4 calories
- 1 gram carbohydrate = 4 calories
- 1 gram fat = 9 calories
A macro calculator splits your TDEE into these nutrients based on your goal and activity level.
🧮 How to Use the TDEE Macro Calculator
Follow these simple steps to get your personalized numbers:
Step 1: Enter Your Age
- Input your current age in years.
Step 2: Select Your Gender
- Choose Male or Female.
Step 3: Enter Your Weight
- Type your weight in kilograms (kg).
- (To convert from pounds, divide by 2.205)
Step 4: Enter Your Height
- Type your height in centimeters (cm).
- (To convert from inches, multiply by 2.54)
Step 5: Choose Your Activity Level
Select the option that best matches your daily lifestyle:
- Sedentary (1.2): Little or no exercise
- Light (1.375): Light exercise 1–3 days/week
- Moderate (1.55): Moderate exercise 3–5 days/week
- Active (1.725): Hard exercise 6–7 days/week
- Very Active (1.9): Very hard exercise or physical job
Step 6: Select Your Goal
- Maintain weight
- Lose fat
- Build muscle
Step 7: Click “Calculate”
- Instantly get:
- Your BMR
- Your TDEE
- Your daily macronutrient targets (grams of protein, carbs, and fats)
📊 Example Calculation
Let’s walk through an example:
- Age: 28
- Gender: Male
- Weight: 70 kg
- Height: 175 cm
- Activity: Moderate (1.55)
- Goal: Maintain weight
Step 1 – Calculate BMR
Using the Harris-Benedict equation:88.362 + (13.397 × 70) + (4.799 × 175) - (5.677 × 28)
= 1707 calories/day
Step 2 – Calculate TDEE1707 × 1.55 = 2646 calories/day
Step 3 – Calculate Macros (40/30/30 split)
- Protein (30%): 794 cal ÷ 4 = 198g
- Carbs (40%): 1058 cal ÷ 4 = 265g
- Fats (30%): 794 cal ÷ 9 = 88g
✅ Results:
- Calories: 2646 kcal/day
- Protein: 198g
- Carbs: 265g
- Fats: 88g

❓ FAQ – TDEE Macro Calculator
Here are 20 commonly asked questions with answers:
1. What is TDEE?
TDEE stands for Total Daily Energy Expenditure, the number of calories you burn in a day.
2. What is BMR?
BMR is your Basal Metabolic Rate—calories burned at complete rest.
3. What are macronutrients?
Macronutrients are protein, carbohydrates, and fats—the main nutrients your body needs daily.
4. How does this calculator work?
It calculates BMR → TDEE → splits calories into macros based on your goal.
5. How accurate is this tool?
It gives very close estimates. Actual needs may vary slightly between individuals.
6. What units should I use?
Weight in kg and height in cm.
7. How do I choose my activity level?
Pick the option that matches your average weekly exercise.
8. What if I want to lose fat?
Choose “Lose weight”, and the calculator will reduce your calories by ~15–20%.
9. What if I want to gain muscle?
Choose “Build muscle”, and the calculator will add ~10–15% more calories.
10. How are macro ratios decided?
Typically 40% carbs / 30% protein / 30% fats — you can adjust later based on preference.
11. Can I change the macro ratios?
Yes, after getting your numbers you can manually adjust macros as needed.
12. How often should I recalculate?
Every 8–12 weeks or after noticeable weight changes.
13. Is this calculator suitable for beginners?
Absolutely! It’s beginner-friendly and simple to use.

Yes. It helps athletes optimize fuel intake for training and recovery.
17. Does it work for both men and women?
Yes. It adjusts formulas based on gender-specific BMR equations.
18. What if I don’t exercise at all?
Select Sedentary activity level to get an accurate TDEE.
19. Can it help with weight maintenance?
Yes. Choose the “Maintain weight” goal to get maintenance calories and macros.
20. What’s the difference between TDEE and BMR?
BMR is the calories you burn at rest.
