Target Body Fat Weight Calculator
Estimate how much weight you need to adjust to reach your target body fat percentage, assuming your current lean body mass is fully preserved.
Goal Weight

Calculation Logic:Since your lean mass is 65.6 kg, reaching 15% fat mass implies that your lean mass accounts for 85% of your total target body weight.
About Body Fat Percentages & Formulas
Body fat percentage represents the total mass of fat divided by total body mass. This tool utilizes three standard estimation methods:
- U.S. Navy Tape Method: Uses neck and waist circumference (plus hip for females) relative to height. A highly accessible standard.
- BMI-based Estimator: Uses age, gender, and BMI (weight/height) for a quick backup estimate.
- Jackson-Pollock 3-Site Caliper: Measures skinfold pinch thickness at three distinct sites. Highly accurate for lean/athletic statures.
