How Many Calories Do You Need Per Day?
Formula
Your daily calorie needs depend on your Basal Metabolic Rate (BMR) and activity level. This calculator uses the Mifflin-St Jeor equation, considered the most accurate BMR formula, and multiplies it by an activity factor to estimate your Total Daily Energy Expenditure (TDEE).
To lose weight, eat about 500 calories below maintenance for roughly 1 pound of loss per week. To gain weight, add 500 calories above maintenance. Always consult a healthcare provider before starting a new diet plan.
Common use cases:
- Weight management planning
- Meal prep and diet design
- Fitness goal setting
