Daily Calorie Intake Calculator
When it comes to health and fitness, knowing how many calories you should eat each day is a game changer. Whether your goal is to lose weight, gain muscle, or simply maintain your current body weight, tracking calorie intake ensures you’re fueling your body the right way.
The Daily Calorie Intake Calculator is a free and easy tool designed to help you estimate your daily calorie needs based on your age, gender, height, weight, and activity level. By using this calculator, you’ll know exactly how many calories you should consume to meet your fitness goals.
What is a Daily Calorie Intake Calculator?
The Daily Calorie Intake Calculator is an online tool that uses proven formulas (like the Mifflin-St Jeor equation) to estimate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE).
- BMR = the calories your body burns at rest
- TDEE = your total calories burned daily (including activity)
By calculating these, the tool tells you how many calories you need each day to:
- Maintain your weight
- Lose weight (calorie deficit)
- Gain weight (calorie surplus)
