What is TDEE and why is it important?

TDEE (Total Daily Energy Expenditure) is the total number of calories you burn in a day, including your basal metabolic rate, daily activities, exercise, and the thermic effect of food. Knowing your TDEE is crucial for setting accurate nutrition goals: eat at TDEE to maintain weight, below TDEE to lose weight, or above TDEE to gain weight. It's the foundation of effective diet planning.

How do I choose the right activity multiplier?

Be honest and slightly conservative when selecting your activity level. Sedentary means desk job with little exercise; lightly active includes walking and light exercise 1-3 days/week; moderately active means moderate exercise 3-5 days/week; very active involves intense exercise 6-7 days/week; extremely active is for athletes training multiple times daily or people with very physical jobs. Most people overestimate their activity level, so when in doubt, choose the lower option.

How often should I recalculate my TDEE?

Recalculate your TDEE every 10-15 pounds of weight change, when your activity level significantly changes, or every 3-4 months during a diet or bulk. Your TDEE decreases as you lose weight and increases as you gain weight or muscle. Regular recalculation ensures your calorie targets remain accurate and you continue making progress toward your goals.

Can I trust my TDEE calculation?

TDEE calculations are estimates with a margin of error of 10-20%. Use the calculated TDEE as a starting point, then track your weight and adjust your calorie intake based on actual results. If you're not losing weight after 2-3 weeks at a supposed deficit, reduce calories by 100-200. If losing too fast (more than 1% body weight per week), increase slightly. Your real-world results are the ultimate truth.

How to Use This Calculator

Enter Your Physical Stats

Input your age, gender, height, and current weight accurately. These variables are used to calculate your basal metabolic rate (BMR), which is the foundation of your TDEE.

Select Your Activity Level

Choose the activity multiplier that best represents your typical week. Include both structured exercise and general daily movement. Be conservative in your estimate to avoid overestimating your calorie needs.

View Your Total Expenditure

Your TDEE represents your maintenance calories—the amount you need to eat to maintain your current weight. This number includes all calories burned from basic metabolism, daily activities, and exercise combined.
