**Introduction**

Determining your daily calorie intake is a crucial step in managing your weight and overall health. Whether you’re looking to maintain your current weight, lose a few pounds, or gain some muscle, knowing the right number of calories to consume is essential. This article provides a calculator to estimate how many calories you should eat per day and explains the factors involved in this calculation.

**Formula**

Calculating the calories you should eat per day involves the Harris-Benedict Equation, which takes into account your weight, height, age, gender, and activity level. The formula may look like this:

Calories Per Day = BMR (Basal Metabolic Rate) x Activity Level

BMR is calculated based on your gender using the following formulas:

- For Males: 88.362 + (13.397 * weight in kg) + (4.799 * height in cm) – (5.677 * age in years)
- For Females: 447.593 + (9.247 * weight in kg) + (3.098 * height in cm) – (4.330 * age in years)

Activity Level is determined by your lifestyle and exercise habits, with options ranging from sedentary to super active.

**How to Use**

Using the “How Many Calories Should I Eat Per Day Calculator” is simple. Enter your weight in kilograms, height in centimeters, age in years, select your gender, and choose your activity level from the drop-down menu. Click the “Calculate” button, and the calculator will provide an estimate of the calories you should eat per day.

**Example**

For example, a 30-year-old male who weighs 75 kg, is 175 cm tall, and has a moderately active lifestyle, may need approximately 2,593 calories per day to maintain his current weight (note that this is a simplified example).
