TDEE = BMR × activity factor (1.2 sedentary → 1.9 very active).
Find total daily energy expenditure from BMR and activity level. Estimates only—not a diagnosis or prescription.
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). Scenario: BMR 1,780 × 1.55 activity → ~2,759 kcal maintenance.
TDEE = BMR × activity factor (1.2 sedentary → 1.9 very active).
Scenario: 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 scenario: 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).
- Scenario on the page: BMR 1,780 × 1.55 activity → ~2,759 kcal maintenance.
How to Calculate TDEE
- 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.
- 2TDEE = BMR × activity factor (1.2 sedentary → 1.9 very active).
- 3Scenario: BMR 1,780 × 1.55 activity → ~2,759 kcal maintenance.
- 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.
