Free Health Calculators

Health numbers are only useful when you know what they mean and where they come from. These calculators follow standard formulas from public health authorities, state every assumption, and compute everything locally in your browser — your measurements never leave your device and are never stored.

Popular tools

BMI Calculator Stable Calculate your Body Mass Index from metric or imperial measurements, with the WHO classification and a healthy weight range.

About this category

Health Calculators on Toolivaro follow the same standard as every other page on the site: each tool shows its formula or method, its assumptions, a worked example, and its limitations, and every result is computed locally in your browser.

All tools are reviewed on a regular schedule. If a calculation looks wrong to you, use the correction link at the bottom of the tool page — corrections are reviewed by a human and the reviewed date is updated when changes land.
