Calculate Your Personalized Daily Calorie Target
Stop guessing your calorie needs. This science-based calculator determines your optimal daily calorie intake using research-backed formulas—no tracking or logging required.

Science-Backed Methodology:
• Our calculator uses the Cunningham formula (1991) combined with individualized factors:
- FFM-Based BMR – More accurate than simple age/weight formulas
- Gender-Specific Activity Levels – Separate PAL values for men and women

- Flexible Goal Setting – Calculate for maintenance, deficit, or surplus
Perfect For:
• Athletes planning nutrition periodization
• Fitness enthusiasts starting a cut or bulk
• Anyone who wants to understand their calorie needs
• Coaches calculating client targets
How It Works:
• Enter your body weight and body fat percentage

Advanced Features:
• Separate calculations for rest days and training days
• Adaptive thermogenesis adjustment for lean individuals
