Body Metrics Calculators
Lean Body Mass Calculator
Estimate how much of your body weight is lean tissue and how much is fat mass.
Page structure
Built for a fast answer first, then a calmer second read.
This calculator page is intentionally layered: quick input and output up top, then a deeper pass through formulas, worked examples, FAQs, and related tools.

Lean mass
58.1 kg lean mass
Lean body mass estimates everything except stored fat: muscle, bone, water, organs, and connective tissue.Results explained
- Lean mass helps set protein targets and interpret scale changes.
- If you have body-fat data, that is usually more useful than a height-weight estimate.
- Track changes over time instead of chasing a single “perfect” number.

- Lean mass includes muscle, bone, water, and organs.
Examples
Quick scenario checks
- 80 kg
- 18% body fat

FAQ
Questions worth ranking for
Each calculator page keeps its own compact FAQ block to widen long-tail coverage.
Is lean mass the same as muscle?
No. Lean mass includes more than muscle.
Why is lean body mass useful?
It helps interpret body composition and nutrition targets.
Should I use body-fat-based or formula-based estimates?
Body-fat-driven estimates are usually more informative.
