TDEE Calculator: Calculate Your Daily Energy Needs for Weight Loss & Maintenance
Are you trying to manage your weight? Use our free and easy-to-use TDEE Calculator to find out how many calories you need daily to maintain, lose, or gain weight. TDEE (Total Daily Energy Expenditure) is a crucial metric that helps you understand your energy balance by calculating the calories burned throughout the day, factoring in your activity level, metabolism, and more. Knowing your TDEE helps you make informed decisions about your diet and fitness goals. For those tracking broader health metrics, our BMR Calculator is an excellent starting point for understanding baseline energy needs.
How the TDEE Calculator Works
To use the TDEE Calculator, follow these simple steps:
- Input Your Personal Details: Enter your age, gender, weight, height, and activity level.
- Calculate Your TDEE: Based on the data provided, the tool will calculate your TDEE, giving you an estimate of how many calories you burn per day.
- Get Results: The calculator will provide your TDEE, which you can then use to create a diet plan aligned with your fitness goals.
Formula Used to Calculate TDEE
The TDEE formula is derived by calculating your Basal Metabolic Rate (BMR) and multiplying it by an activity factor. Here’s how it works:
TDEE = BMR x Activity Level
Where:
- BMR is your Basal Metabolic Rate, the number of calories your body burns at rest to maintain basic bodily functions (heart rate, respiration, etc.).
- Activity Level is a factor based on your physical activity, ranging from sedentary to highly active.

BMR Formula Examples
Mifflin St-Jeor Equation (common for most people):
For men:
BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age (years) + 5
For women:
BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age (years) − 161
Harris-Benedict Equation (another option):
Similar to Mifflin, but slightly different in calculation specifics. Once your BMR is calculated, it is adjusted based on your activity level to get an estimate of your TDEE.
What Does TDEE Tell You?
TDEE provides an estimate of how many calories your body needs daily to sustain your current weight.
- If you consume fewer calories than your TDEE, you’ll lose weight (create a calorie deficit).
- If you consume more, you’ll gain weight (create a calorie surplus).
- If you match your intake with your TDEE, you’ll maintain your weight.
How to Use Your TDEE
- For Weight Loss: To lose weight, you should aim for a calorie intake below your TDEE. A typical recommendation is a 10-20% reduction in calories for steady weight loss.
- For Weight Gain: If you’re looking to build muscle or gain weight, you’ll need to consume more calories than your TDEE.
- For Maintenance: To maintain your weight, try to consume the same number of calories as your TDEE.
Frequently Asked Questions (FAQ)
What is the difference between TDEE and BMR?
TDEE includes all the energy your body burns in a day, factoring in physical activity, food digestion, and more, while BMR only measures calories burned at rest to maintain vital body functions.
How do I calculate my TDEE for weight loss?
To calculate TDEE for weight loss, use our TDEE Calculator and then subtract 10-20% of your total calorie intake to create a calorie deficit.
What is the best TDEE calculator?
Our TDEE Calculator is accurate and easy to use, offering precise results based on scientific formulas and personal details you provide.
Can I use TDEE to maintain my weight?
Yes, TDEE is a useful tool to determine the exact amount of calories you need daily to keep your current weight. Adjust your calorie intake based on your TDEE to maintain or modify your weight as desired.
How does exercise affect TDEE?
Exercise increases your activity factor, meaning it boosts your TDEE. More physical activity means your body needs more calories to sustain your energy levels.
How does protein impact TDEE?
Protein increases the thermic effect of food (TEF), meaning your body burns more calories during digestion when you eat protein compared to fats or carbs.
Does age affect TDEE?
Yes, as you age, your BMR tends to decrease, which also lowers your TDEE. Therefore, older individuals may need fewer calories to maintain their weight.
Can I calculate my TDEE without a calculator?
Yes, you can use the TDEE formula manually, but our online tool makes the process much quicker and more accurate!
How often should I recalculate my TDEE?
Recalculate your TDEE periodically, especially when your weight, activity level, or fitness goals change.
