Body Fat Percentage Calculator
Measure your body composition accurately with our U.S. Navy method body fat calculator. Get precise results for body fat percentage, BMI, lean mass, and more.
Understanding Body Fat Percentage
Body fat percentage is a key indicator of health and fitness that measures the proportion of fat in your body compared to your total weight. Unlike BMI, it distinguishes between fat mass and lean mass, providing a more accurate assessment of your body composition.
Why Measure Body Fat Percentage?
- Health Assessment: High body fat increases risk of heart disease, diabetes, and other conditions
- Fitness Tracking: More accurate than weight alone for measuring progress
- Performance Optimization: Athletes use it to reach peak performance levels
- Goal Setting: Helps establish realistic fitness and weight loss targets
About the U.S. Navy Method
This calculator uses the U.S. Navy’s body fat formula, which has been scientifically validated as accurate within 1-3% of more complex methods like DEXA scans when measurements are taken properly. The method uses circumference measurements and height to estimate body fat percentage.
How to Get Accurate Measurements
- Measure in the morning before eating
- Use a flexible, non-stretch tape measure
- For waist: Measure at navel (men) or narrowest point (women)
- For neck: Measure below the larynx (Adam’s apple) with tape sloping downward
- Take multiple measurements for consistency
Body Fat Categories
For Men: Essential (2-5%), Athletes (6-13%), Fitness (14-17%), Average (18-24%), Obese (25%+)
For Women: Essential (10-13%), Athletes (14-20%), Fitness (21-24%), Average (25-31%), Obese (32%+)

What is Body Fat Percentage?
Your body fat percentage is the proportion of fat your body contains compared to your total body weight. It includes both essential body fat, which is necessary for normal bodily functions, and stored fat. The stored fat is often what people aim to reduce for better health and fitness.
Calculating body fat percentage helps you understand how much of your body is fat mass compared to lean mass (muscles, bones, water, etc.). This metric is more useful than just tracking weight because two people may weigh the same but have different body fat percentages, indicating different levels of fitness and health.
Why Tracking Your Body Fat is Important
Tracking your body fat provides a more complete picture of your health than merely stepping on a scale. For example:
Health Risks: Higher body fat percentages, especially when classified as obese, are linked to various health issues like heart disease, diabetes, and hypertension.
Fitness Monitoring: As you work out and build muscle, your body weight may stay the same, but your body fat percentage can decrease, which indicates progress.
Setting Realistic Goals: Knowing your body fat percentage allows you to set more precise goals. Instead of just aiming to lose weight, you can focus on losing fat while maintaining or gaining lean muscle mass.
How the Body Fat Calculator Works
Our Body Fat Calculator uses the U.S. Navy Method to estimate your body fat percentage based on key measurements:
- Height
- Weight
- Neck circumference
- Waist circumference
- (For females) Hip circumference
The calculator takes these inputs, applies formulas specifically designed for men and women, and delivers an estimate of your body fat percentage, body fat mass, and lean body mass.
Additionally, our tool calculates your Body Mass Index (BMI), another popular metric to assess body composition, and provides an estimate of how much fat you need to lose to reach an ideal body fat percentage based on age and gender.
How to Use the Body Fat Calculator: Step-by-Step Instructions
Using the Body Fat Calculator is straightforward and doesn’t require any advanced knowledge. Follow these steps to get an accurate estimate of your body fat percentage.
Step 1: Select Your Units (US or Metric)
Our calculator allows you to use either US units (pounds, feet, inches) or Metric units (kilograms, centimeters).
If you are familiar with the imperial system (used mostly in the U.S.), select US Units.
If you prefer the metric system, select Metric Units. This setting will automatically adjust the placeholders for entering weight, height, and other measurements to reflect your choice.
Step 2: Select Your Gender
Choose your gender in the dropdown list. The formulas for calculating body fat differ for men and women due to differences in fat distribution.
Step 3: Enter Your Age
Input your age. Age plays a crucial role in determining ideal body fat levels, as our body composition tends to change as we grow older.
Step 4: Input Your Weight
Depending on your choice of unit:
US Units: Enter your weight in pounds (lbs).
Metric Units: Enter your weight in kilograms (kg). Make sure to use a scale to get the most accurate result.
Step 5: Measure and Enter Your Height
For accurate body fat calculation, your height is essential. If you’re using:
US Units: Input your height in feet and inches.
Metric Units: Enter your height in centimeters.
Step 6: Measure and Enter Neck, Waist, and (for females) Hip Circumference
Neck Circumference: Measure around the largest part of your neck.
Waist Circumference: Measure around the smallest part of your waist for males, and around the largest part of your waist for females.
Hip Circumference (Females): Measure around the widest part of your hips.
Once you’ve entered these measurements, click Calculate to generate your body fat percentage and related metrics.
Interpreting Your Results
After you’ve entered all the required information, the Body Fat Calculator will display a series of results. Here’s how to interpret each of them:
Body Fat Percentage
This is your total body fat percentage based on the measurements provided. It tells you what percentage of your body is made up of fat. The ideal body fat percentage varies depending on your gender and age.
Men: Ideal body fat is typically between 8-20% depending on age.
Women: Ideal body fat is typically between 18-30% depending on age.
Body Fat Mass
This metric tells you the actual mass of fat in your body. For example, if you weigh 70 kg and have 20% body fat, your body fat mass is 14 kg.
Lean Body Mass
Your lean body mass is everything in your body that isn’t fat, such as muscles, bones, organs, and water. This is calculated by subtracting your body fat mass from your total body weight.
Ideal Body Fat Percentage
The calculator provides an estimate of your ideal body fat percentage based on age and gender. This helps you understand what body fat percentage is healthy for you.
BMI Calculation
Body Mass Index (BMI) is a rough estimate of whether your weight is healthy relative to your height. A BMI over 25 is generally considered overweight, while a BMI over 30 is classified as obese. However, BMI doesn’t take muscle mass into account, so it’s less accurate than body fat percentage.
Fat to Lose
This section gives you an estimate of how much body fat you need to lose to reach the ideal body fat percentage. It provides a clear target, helping you focus on fat loss rather than just weight loss.
Tips for Accurate Measurements
To get the most accurate results from the Body Fat Calculator, follow these tips:
- Use a Reliable Scale: Make sure your weight is up-to-date by using a reliable scale.
- Measure Height and Circumference Carefully: For best results, use a tape measure and measure around your neck, waist, and hips accurately. Avoid loose clothing while measuring, and take measurements in the morning for consistency.
- Reassess Regularly: Body fat percentage can fluctuate, so it’s good practice to track it regularly, especially if you’re working toward a fitness goal.
Conclusion: Achieve Your Fitness Goals
Understanding your body fat percentage is essential for tracking your health and fitness progress. Unlike weight, which can be misleading due to muscle mass and other factors, body fat percentage offers a more accurate picture of your health.
Our Body Fat Calculator is a simple yet powerful tool that helps you determine where you stand in terms of body composition.
