TDEE Calculator
If you’ve ever wondered how many calories you burn in a day, you’re not alone. Knowing this number is essential whether you want to lose weight, build muscle, or simply maintain your current weight.
Our TTDE Calculator is a simple, accurate, and fast way to figure out your Total Daily Energy Expenditure (TDEE or TTDE) and Basal Metabolic Rate (BMR). It helps you understand how much energy your body uses each day so you can create the perfect meal and fitness plan for your goals.
⚡ What is TTDE?
TTDE (Total Daily Energy Expenditure) is the total number of calories your body burns each day. It includes:
- 🫁 Your BMR (Basal Metabolic Rate) — the calories you burn at rest
- 💪 Calories burned during physical activities like walking, exercising, or working
The formula is simple:
TTDE = BMR × Activity Level
Where:
- BMR is calculated from your age, gender, weight, and height
- Activity level is a multiplier that represents how active you are daily
🧮 How to Use the TTDE Calculator
Using the TTDE Calculator is quick and easy. Follow these steps:
Step 1: Enter Your Age
- Type your age in years.
- This helps adjust your metabolic estimate.
Step 2: Select Your Gender
- Choose Male or Female from the dropdown menu.
- Men and women have slightly different BMR formulas.
Step 3: Enter Your Weight
- Input your weight in kilograms (kg).
- (If you know your weight in pounds, divide by 2.205 to get kg.)
Step 4: Enter Your Height
- Input your height in centimeters (cm).
- (If you know it in inches, multiply by 2.54 to get cm.)
Step 5: Choose Your Activity Level
- Sedentary (1.2): Little or no exercise
- Light (1.375): Light exercise 1–3 times per week
- Moderate (1.55): Moderate exercise 3–5 times per week
- Active (1.725): Hard exercise 6–7 times per week
- Very Active (1.9): Physical job or intense exercise
Step 6: Click “Calculate”
- The calculator will display:
- Your BMR (Basal Metabolic Rate)
- Your TTDE (Total Daily Energy Expenditure) in calories/day
Step 7: Copy or Reset
- Use the Copy Result button to copy your results.
- Click Reset to start again.
📊 Example Calculation
Here’s an example to help you understand the process:
- Age: 25
- Gender: Female
- Weight: 60 kg
- Height: 165 cm
- Activity Level: Light (1.375)
Step 1 – Calculate BMR (female formula):447.593 + (9.247 × 60) + (3.098 × 165) - (4.330 × 25)
= 447.593 + 554.82 + 511.17 – 108.25
= 1405.3 calories/day
Step 2 – Calculate TTDE:1405.3 × 1.375 = 1932.3 calories/day
✅ This means she needs about 1932 calories/day to maintain her current weight with light activity.
