TDEE Calculator

Estimate total daily energy expenditure from body measurements and a selected activity level.

Working with TDEE Calculator

TDEE combines an estimated basal energy requirement with an activity factor. Use the result as a starting estimate for understanding energy needs, then review how the selected activity level changes it. It is not a direct measurement of your metabolism.

How to use TDEE Calculator

  1. Enter age, height, weight, and the available formula inputs.
  2. Choose an activity level and review the assumptions.
  3. Compare the basal and total daily estimates in the results.

TDEE Calculator example

Keep the body measurements fixed and compare two activity selections to see how strongly that assumption affects the daily estimate.

What to expect from the result

Prediction equations and activity factors have individual error. This adult planning tool is not a clinical assessment or a dietary prescription, particularly during pregnancy, growth, or illness.
