A Calorie Calculator is a free online tool that helps you estimate your daily calorie requirements quickly and accurately. Whether your goal is to lose weight, gain muscle, or maintain your current weight, our Calorie Calculator provides personalized results based on your age, gender, weight, height, and activity level.
What is a Calorie Calculator?
A Calorie Calculator calculates the number of calories your body needs each day to maintain its current weight, taking into account your basal metabolic rate (BMR) and activity level. It helps you plan meals, track nutrition, and achieve your fitness goals effectively.
How Does the Calorie Calculator Work?
Our Calorie Calculator uses standard formulas like the Mifflin-St Jeor Equation to estimate your Basal Metabolic Rate (BMR) and total calorie needs:
For Men: BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age (years) + 5
For Women: BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age (years) − 161
Your total daily calorie requirement is then calculated by multiplying BMR with an activity factor based on your lifestyle: sedentary, lightly active, moderately active, very active, or extra active.
