HTML Website GeneratorEstimate your daily calorie needs based on your body measurements, activity level, and fitness goals.
These results are estimates, not exact measurements. Your actual calorie needs may vary depending on muscle mass, daily movement, metabolic differences, and individual health factors.
Your daily calorie needs represent the amount of energy your body uses to support essential functions, everyday movement, exercise, and recovery. Understanding your estimated calorie needs can help you create a practical nutrition plan for maintaining your weight, losing body fat, or building muscle.
| Term | What It Means |
|---|---|
| Basal Metabolic Rate (BMR) | Estimated calories your body needs at rest to maintain essential functions. |
| Total Daily Energy Expenditure (TDEE) | Estimated total calories burned throughout a typical day, including activity. |
| Calorie Deficit | Consuming fewer calories than your body uses over time. |
| Calorie Surplus | Consuming more calories than your body uses over time. |
This calculator uses the Mifflin-St Jeor equation to estimate your basal metabolic rate. The equation considers your body weight, height, age, and the sex-based constant used by the formula.
Your estimated BMR is then multiplied by an activity factor to calculate Total Daily Energy Expenditure (TDEE). The selected nutrition goal adjusts that estimate to provide a starting daily calorie target.
If your goal is to build muscle, a moderate calorie surplus may help support training and recovery. Consistent resistance training, sufficient protein, and adequate rest also play important roles. More calories alone do not guarantee more muscle growth.
Use your calculated target as a starting point. Monitor your weight trends, training performance, and recovery over several weeks, then adjust your calorie intake based on your progress.
Choose U.S. customary units to enter your height in feet and inches and your weight in pounds. Prefer metric measurements? Switch to centimeters and kilograms at any time. Your measurements are automatically converted, while the calculator uses the same underlying calorie equation.
