SnapCalDaily calorie needs calculator
This calculator uses the National Academies’ 2023 adult EER equations to estimate daily energy needed to maintain weight. Inputs are calculated only in your browser and are not uploaded.
Who it is for
Adults age 19 and over who are not pregnant or breastfeeding. Population equations cannot replace indirect calorimetry or an individual medical assessment.
How to use the result
EER is a starting estimate for energy balance. Actual needs change with activity, body composition, illness, medication and environment; use a consistent weight trend to refine the estimate.
