Disclaimer

All calculators and guides on CalcTools are provided for general information and education.

Health calculators

Health calculators such as BMI, due date or heart-rate zones use published formulas and reference ranges, mostly from the World Health Organization and similar bodies. They cannot take your full medical history into account and are not a diagnosis. Always talk to a doctor, midwife or other qualified professional about your health.

Money calculators

Financial results are simplified estimates. Real loans, investments and taxes depend on terms, fees and rules that differ by country and provider. They are not financial advice.

Vehicles and technical tools

Automotive and technical calculators follow common formulas and typical values. Always check your owner's manual, the manufacturer's specification or a qualified mechanic or engineer before acting on a result.

Errors

We check every calculator against worked examples, but mistakes can happen. If you think a result is wrong, please tell us at contact@calctools.biz.id.
