How this calculator works

Find total daily energy expenditure from BMR and activity level. Estimates only—not a diagnosis or prescription. TDEE = BMR × activity factor (1.2 sedentary → 1.9 very active). Example: BMR 1,780 × 1.55 activity → ~2,759 kcal maintenance.

TDEE = BMR × activity factor (1.2 sedentary → 1.9 very active).

Example: BMR 1,780 × 1.55 activity → ~2,759 kcal maintenance.

When to use this TDEE

Common use cases

  • Find total daily energy expenditure from BMR and activity level.
  • Sanity-check with this case: BMR 1,780 × 1.55 activity → ~2,759 kcal maintenance.
  • The relationship is: TDEE = BMR × activity factor (1.2 sedentary → 1.9 very active).

Localized examples

  • Health, Fitness & Wellness: the example on this page uses the same formula as the widget.

What you get

  • Fields: Sex (0=F, 1=M), Age (years), Weight (lbs), Height (in)
  • TDEE = BMR × activity factor (1.2 sedentary → 1.9 very active).
  • Example on the page: BMR 1,780 × 1.55 activity → ~2,759 kcal maintenance.

How to Calculate TDEE Step-by-Step

  1. 1Enter Sex (0=F, 1=M), Age (years), Weight (lbs), then the remaining fields. Use the values you have, not a catalog average, unless that is all you know.
  2. 2TDEE = BMR × activity factor (1.2 sedentary → 1.9 very active).
  3. 3Worked case: BMR 1,780 × 1.55 activity → ~2,759 kcal maintenance.
  4. 4If this number would change a drug, a diet, or a return-to-play call, take it to a clinician. The page never examined you.

Governing formula

TDEE = BMR × activity factor (1.2 sedentary → 1.9 very active).

BMR 1,780 × 1.55 activity → ~2,759 kcal maintenance.

Example: set Sex (0=F, 1=M) = 1, Age (years) = 30, Weight (lbs) = 180, then read the result.

  • The formula (TDEE = BMR × activity factor (1.2 sedentary → 1.9 very active).) does not see labs, medications, sleep, or injury history. A clinician does.
  • Nothing here is uploaded for the calculation itself.

Very usable on mobile. Would love a save/export option later, but the math feels solid.

Simple inputs, clear outputs. This replaced three bookmarks I used to juggle.
