Required Daily Calories: 0 calories

Introduction

Understanding your daily calorie needs is essential for maintaining a healthy and balanced diet. The “How To Calculate Required Calories Per Day” calculator is a practical tool that estimates your daily calorie requirements based on your weight, height, age, gender, and activity level. Whether you aim to maintain your current weight, lose weight, or gain muscle, knowing your required calorie intake is a crucial step in your nutritional journey.

Formula

The calculator uses two distinct formulas to calculate daily calorie needs based on gender:

For males: Required Calorie Needs = 66 + (6.23 * weight) + (12.7 * height) – (6.8 * age)

For females: Required Calorie Needs = 655 + (4.35 * weight) + (4.7 * height) – (4.7 * age)

These formulas consider factors such as weight, height, age, and gender to provide a personalized calorie estimate. The calculator then adjusts this estimate based on your selected activity level, using a multiplier to account for daily energy expenditure.

How to Use

Using the calculator is straightforward. Here’s how to do it:

1. Enter your weight in pounds in the “Your Weight” field.
2. Input your height in inches in the “Your Height” field.
3. Add your age in the “Your Age” field.
4. Select your gender from the dropdown menu.
5. Choose your activity level from the “Activity Level” dropdown.
6. Click the “Calculate” button, and the estimated daily required calories will be displayed.

Example

For example, if you are a 35-year-old male who weighs 180 pounds, is 70 inches tall, and maintains a moderately active lifestyle, you can calculate your required daily calories as follows:

Required Calorie Needs = 66 + (6.23 * 180) + (12.7 * 70) – (6.8 * 35) = 2,320.6 calories per day

With a moderately active lifestyle, your daily required calories would be 2,320.6 * 1.55 = 3,592.43 calories per day.
