Introduction
Fitness will begin by understanding the composition of your body and body fat percentage will help you have a more definite view than weight alone. A Percentage Body Fat Calculator is a calculation tool based on measurements of skinfolds to determine the amount of fat that is consumed through the calculation of the percentage body fat, so that people can custom-tailor their diet, exercise programs, or fitness programs. It is a tool based on the proven techniques to give practical information to sportsmen, amateurs, or any other person who tracks progress.
It is usually used together with a body fat percentage estimator by gym-goers and health trackers looking to compare it over time. It is a simple skinfold calculator of any caliper which includes such sites as chest and thigh. It will be handy with body composition analysis or a fat percentage tool particularly where scales have failed. These insights drive changes towards sustainability in the routine centered in wellness.
How to Use Percentage Body fat Calculator
The Percentage Body Fat Calculator will help you through the inputs and give you the reading with the calipers and come up with an accurate estimate. Without haste gather up a skinfold caliper and follow the steps:

- Enter Age: Enter the number of years in the field.
- Enter Weight: Enter your present weight in kilograms (kg).
- Enter Chest: Measure and enter into the computer the skinfold at the chest in millimeters (mm).
- Enter Abdomen: Enter, in mm, the abdomen skinfold.
- Enter Thigh: Introduce the Thigh skinfold figure in mm.
- Enter Triceps: Type triceps skinfold mm.
- Enter Axilla: Enter the skinfold of the axilla (underarm) in mm.
- Enter Subscapula: Enter the subscapula (below shoulder blade) in mm.
- Enter Suprailiac: Valve in mm Add suprailiac skinfold (above hip bone).
- Click Calculate: To see your body fat percentage, press the blue button that has the Calculate printed on it.
- Click Reset: To restart all over again, press the reset button.
Formula and Calculation Method
This Percentage Body Fat Calculator employs the Jackson-Pollock 7-site skinfold method to first calculate body density (BD), then derives percentage body fat (%BF) via the Siri equation: %BF = (495 / BD) – 450.
Sum the seven skinfold measurements (S) in mm.
For men: BD = 1.112 – (0.00043499 × S) + (0.00000055 × S²) – (0.00028826 × age).
For women: BD = 1.097 – (0.00046971 × S) + (0.00000056 × S²) – (0.00012828 × age).
Weight informs overall composition but isn’t in the core %BF formula.
Example: A 30-year-old man with S = 100 mm. BD = 1.112 – (0.00043499 × 100) + (0.00000055 × 10,000) – (0.00028826 × 30) ≈ 1.065. %BF = (495 / 1.065) – 450 ≈ 14.6%. This indicates a lean, athletic range.

FAQs
What skinfold sites does it measure?
- It uses seven: chest, abdomen, thigh, triceps, axilla, subscapula, and suprailiac for comprehensive coverage.
How accurate is the Jackson-Pollock method?
- It offers 3-4% error margins, comparable to DEXA scans when measurements are precise.
Do I need a caliper tool?
- Yes, a reliable skinfold caliper ensures mm accuracy; pinch perpendicular to the site.
What if my weight changes but skinfolds don’t?
- Recalculate periodically—%BF reflects fat shifts better than weight alone.
Is it suitable for all ages?
- Best for adults 18+; consult pros for youth or advanced needs.
