1. Estimates, not verdicts
Each calculator applies a published, standard formula to the values you enter. A formula is a model: it leaves out things that matter in real life, such as lender fees, taxes, your medical history or local building codes.
2. Financial and tax results
Loan, mortgage, investment, retirement and tax figures are illustrations. Rates, rules and fees differ by lender, country and year. Confirm any decision with a qualified advisor and the official documents of your institution.
3. Health and fitness results
BMI, calorie, body composition, pregnancy and similar results are population-level estimates. They are not a diagnosis. Talk to a doctor or other qualified health professional before acting on them.
4. Engineering, construction and science
Structural, electrical, material and chemistry results are simplified. They do not replace calculations stamped by a licensed professional or the codes that apply where you build.
5. Errors
We work to keep every formula correct, but mistakes happen. Each result shows its formula and inputs so you can check it. If a number looks wrong, tell us at [email protected].
