How It Works
How It Works
The TDEE (Total Daily Energy Expenditure) calculator estimates how many calories your body needs each day to maintain your current weight. It first calculates your Basal Metabolic Rate (BMR), which is the number of calories your body uses at rest to keep you alive.
Then, it multiplies that number by your activity level. This adjustment accounts for the calories you burn through daily movement and exercise, giving you a more realistic daily calorie estimate.
- Uses your weight, height, and age to estimate calories burned at rest
- Adds 5 in the formula as part of the standard BMR calculation
- Multiplies the result by your selected activity level
- Higher activity levels increase your total calorie needs
Understanding the Results
Your result shows the approximate number of calories you need per day to maintain your current weight. If you consistently eat around this amount, your weight should stay relatively stable.
To lose weight, you would typically eat fewer calories than your TDEE. To gain weight, you would eat more. The result is an estimate, so small adjustments may be needed based on real-world progress.
- Result = daily calories needed to maintain weight
- Eat less than this number to lose weight
- Eat more than this number to gain weight
- Use it as a starting point and adjust if needed
Frequently Asked Questions
What is TDEE and why is it important?
TDEE stands for Total Daily Energy Expenditure. It represents the total number of calories your body burns in a day, including basic bodily functions and physical activity. Knowing your TDEE helps you plan calorie intake for weight loss, maintenance, or muscle gain.
When should I use a TDEE calculator?
You should use a TDEE calculator when setting nutrition or fitness goals, such as losing fat, building muscle, or maintaining your current weight. It gives you a starting point for how many calories you need daily. You can then adjust your intake based on your progress over time.
How do I choose the correct activity level?
Select the activity level that best matches your average weekly exercise routine. For example, choose "Sedentary" if you rarely exercise and have a desk job, or "Moderately active" if you work out 3–5 days per week. Be honest about your activity to get the most accurate estimate.
Is this TDEE calculation accurate for everyone?
This calculator provides an estimate based on a standard metabolic formula. Individual factors like body composition, genetics, and medical conditions can affect your true calorie needs. Use the result as a guideline and adjust based on real-world results.
How can I use my TDEE to lose or gain weight?
To lose weight, consume 300–500 fewer calories than your TDEE per day. To gain weight or build muscle, aim for a 200–500 calorie surplus. Monitor your progress weekly and adjust your intake if your weight change is too fast or too slow.
Should I recalculate my TDEE over time?
Yes, you should recalculate your TDEE whenever your weight, activity level, or age changes significantly. Even a 5–10 kg weight change can meaningfully affect your calorie needs. Rechecking every few months helps keep your nutrition plan accurate.
