This benchmark analysis utilizes your gender, age, weight, height, neck, and waist measurements, Measurements can be taken in either U.S. units (pounds and inches) or metric units (kilograms and centimeters). With these parameters inputted, you can determine your body fat percentage effectively.

Understanding the Results

Your calculated body fat percentage provides significant insight into your body composition. For instance, a body fat percentage of 15.3% typically indicates a fit individual, while values around 25% categorize someone as obese. It's crucial to aim for a range that aligns with your fitness goals; for example, athletes generally may target a body fat percentage of around 6% to 11%. Additionally understanding your lean body mass—such as if you have 23.2 lbs of fat mass—can offer guidance on the fat you may need to lose to reach your ideal body fat percentage.

Body Fat Calculator

Body fat percentage

Body fat percentage is a key indicator of health, representing the proportion of fat your body holds compared to your total body weight. It includes both essential fat, which is necessary for bodily functions, and storage fat.
Why is Body Fat Percentage Important?
Health Risk Assessment: High body fat can increase the risk of chronic diseases like heart disease, diabetes, and certain cancers.
Fitness Progress: It's a more accurate measure of fitness than weight alone, as it differentiates between fat and muscle mass.
Body Composition: Understanding your body fat helps you tailor your diet and exercise to achieve a healthier body composition.
The U.S. Navy Body Fat Calculation Method
The U.S. Navy method is a simple and widely used way to estimate body fat percentage using basic body measurements. While not as precise as clinical methods like DEXA scans, it provides a good estimate you can do at home.
What You'll Need:
Measuring tape
Calculator
Measurements Required:
Men: Neck circumference, waist circumference, height.
Women: Neck circumference, waist circumference, hip circumference, height.
Steps for Men:
Measure Neck: Measure around your neck just below the larynx, keeping the tape horizontal.
Measure Waist: Measure your waist at the navel (belly button), ensuring you're relaxed and not holding your breath.
Measure Height: Stand tall and measure your height.
Formula for Men:
Body Fat % = 495 / (1.0324 - 0.19077 * log10(waist - neck) + 0.15456 * log10(height)) - 450
Steps for Women:
Measure Neck: Measure around your neck just below the larynx, keeping the tape horizontal.
Measure Waist: Measure your waist at the smallest point, usually above the navel.
Measure Hips: Measure around the widest part of your hips.
Measure Height: Stand tall and measure your height.
Formula for Women:
Body Fat % = 495 / (1.29579 - 0.35004 * log10(waist + hip - neck) + 0.22100 * log10(height)) - 450
Example Calculation (for a hypothetical man):
Waist: 34 inches
Neck: 15 inches
Height: 70 inches
Body Fat % = 495 / (1.0324 - 0.19077 * log10(34 - 15) + 0.15456 * log10(70)) - 450
Body Fat % = 495 / (1.0324 - 0.19077 * log10(19) + 0.15456 * log10(70)) - 450
Body Fat % = 495 / (1.0324 - 0.19077 * 1.27875 + 0.15456 * 1.84510) - 450
Body Fat % = 495 / (1.0324 - 0.24395 + 0.28522) - 450
Body Fat % = 495 / 1.07367 - 450
Body Fat % = 461.02 - 450
Body Fat % = 11.02%
So, for this hypothetical man, the body fat percentage is approximately 11.02%.
