Maintenance Calories: estimate Calories to Maintain Weight
Estimate maintenance calories from a known TDEE or profile and show the activity assumptions used.
Inputs this tool uses
- Age
- Sex used by the formula
- Height
- Weight
- Activity level
What you get
Estimated daily maintenance energy from Mifflin–St Jeor BMR × activity factor.
How to use the Maintenance Calories Calculator
- Enter age, sex used by the formula, height and the other fields relevant to this calculation.
- Select any method, activity level or option shown on this page, then choose Calculate.
- Read the main result together with the supporting values, method, assumptions and limitations below before using the estimate.
How this calculation works
TDEE multiplies an estimated resting-energy value by a transparent activity factor. Activity factors are heuristics, not measurements.
Example calculation
The sample values loaded into the calculator produce 2250 kcal/day. This example exists to show how the output is structured; replace the sample values with your own inputs for your calculation.
Assumptions and limitations
- Energy and nutrient outputs are estimates or general reference values, not individualized treatment targets.
- Adult calorie-goal tools should not be used for children, pregnancy or medical nutrition therapy unless the page explicitly supports that life stage.
