Calorie Deficit Calculator
Calculate an estimated calorie target from TDEE and a daily or percentage deficit.
Estimated result
Check the entered values.
The energy equivalent is theoretical; actual weight does not change linearly or predictably.
Adjusting maintenance
The target subtracts an amount or percentage from TDEE and shows weekly deficit plus a theoretical energy equivalent.
Not a weight prediction
Metabolic adaptation, adherence, and activity changes prevent calories from becoming a linear promise.
Frequently asked questions
Does weekly deficit guarantee weight loss?
No. It is a mathematical equivalent, not an individual prediction.
Is personal data sent to a server?
No. Calculations run locally in your browser and these values are not stored by default.
Can I use the result as medical advice?
No. It is an educational reference and does not replace individual assessment.
