TDEE Calculator

Calculate your Total Daily Energy Expenditure to find out how many calories you burn each day.

This calculator provides formula-based estimates for educational purposes only. Results should not replace professional medical advice, diagnosis, or treatment. If symptoms, medications, pregnancy, eating behavior concerns, injury, or chronic health conditions are involved, use the result carefully and consult a qualified healthcare professional. See the Body Tally disclaimer and how the calculators work page for more detail.

How to use this calculator

Enter your age, sex, height, and weight.
Select the activity level that best matches an average week.
Calculate your total daily energy expenditure.
Use the result as an estimate of maintenance calories.

Example

If your BMR is 1,600 calories and your activity multiplier is 1.55, your estimated TDEE is about 2,480 calories per day.

Activity multipliers are broad estimates. Track trends over time if you use TDEE for weight management.

Frequently Asked Questions

What is TDEE?

TDEE (Total Daily Energy Expenditure) is the total number of calories you burn in a day, including your BMR (resting calories) plus calories burned through physical activity and exercise.

How do I choose my activity level?

Sedentary: little or no exercise. Light: exercise 1-3 days/week. Moderate: exercise 3-5 days/week. Active: exercise 6-7 days/week. Very Active: intense exercise daily or physical job. Be honest about your activity to get accurate results.

How can I use TDEE for weight loss?

To lose weight, consume fewer calories than your TDEE. A deficit of 500 calories/day typically results in about 0.5 kg (1 lb) weight loss per week. Avoid extreme deficits and consult a healthcare provider for safe weight loss.

Should I eat my TDEE to maintain weight?

Yes, eating at your TDEE should maintain your current weight. To gain weight, eat above your TDEE. To lose weight, eat below it. Track your progress and adjust as needed.

About This TDEE Calculator

Use the TDEE calculator to estimate total daily energy expenditure, which is the approximate number of calories used across rest, movement, exercise, digestion, and normal daily activity. TDEE helps frame maintenance calorie planning.

Body Tally keeps the calculator near the top of the page and adds this guide so you can understand what the tool does, how the inputs affect the result, and what the result can and cannot tell you. Health and fitness formulas are useful for planning, but they work best when treated as estimates and compared with real trends, symptoms, training history, and professional guidance when appropriate.

How the Math Works

TDEE is commonly estimated by multiplying BMR by an activity factor. Higher activity factors increase the calorie estimate, but activity selection is subjective.

The formulas use simplified inputs so they can be calculated quickly in a browser. They do not know your medical history, medications, hormones, lab results, training recovery, sleep, stress, or diagnosis. Use the answer as a starting point, then refine it with consistent measurements and qualified advice when the decision affects health.

When to Pause and Get Personal Guidance

Calculator results are useful for learning and planning, but they should not be the only basis for decisions when symptoms, medications, chronic conditions, pregnancy, eating disorder history, injury, or major changes in activity are involved.

If the estimate feels surprising, repeat the measurement, check your unit settings, compare one related calculator, and read the matching guide before acting on the number. Body Tally is built to help you ask better questions, not to replace qualified care.
