Disclaimer

Everything on 1plus1 is published for information. A calculator applies a formula to the numbers you give it; it does not know your situation, your contract, your jurisdiction or your health.

Results are estimates, not offers. Real loan, savings, tax and investment figures depend on fees, compounding conventions, payment dates, local rules and eligibility criteria that vary between institutions and countries. Always confirm with the institution concerned or with a qualified adviser before committing.

Health indicators are population estimates. They cannot diagnose, screen or replace an examination. If a result concerns you, or contradicts what you have been told by a professional, trust the professional and speak to them.

Material and dimension estimates do not replace a structural study, a building code, or the instructions of a manufacturer. Always allow for the tolerances and safety factors your project requires.

If you find a result that looks wrong, tell us — with the values you entered and the source you compared against. Corrections are a priority.
