Calculator results and assumptions

Each calculator applies a formula to the values you type in. Any output is a function of those inputs and of the assumptions stated on the page. Concretely, that means:

• Your inputs drive the answer. We do not check, validate or correct what you enter. A plausible-looking result can still be wrong if a figure was mistyped, entered in the wrong unit, or taken from an outdated statement.
• Assumptions are disclosed, not hidden. Rounding conventions, currency, default rates and the point at which a value is measured are printed with the result. Change an assumption and the correct answer changes with it.
• Rules vary by place and time. Tax, employment, benefits, building and safety rules differ between countries and are revised regularly. A calculator cannot detect which regime applies to you.
• Estimates are not guarantees. Real outcomes include costs, fees, interest, penalties, inflation and human factors that a formula does not model. Treat every figure as an estimate to be verified, not a promise.
• Verify before you commit. Before acting on a result that affects money, health, safety or legal rights, check it against the primary source or a qualified professional.

If you believe a calculator is producing an incorrect result, tell us through the contact page and include the tool, your inputs and the expected result so it can be checked against its source.
