Disclaimer

Results are estimates

Every calculator on this site provides informational, general-purpose estimates — not official or certified figures. Results can be affected by the values you enter, the assumptions behind each formula, rounding, interest rates, units, dates, and other variables. Small changes in any of these can noticeably change a result.

Financial calculators

Financial calculators — loan, mortgage, investment, tax, and similar tools — do not provide financial, tax, investment, lending, or legal advice. Actual loan terms, investment returns, and tax rules depend on your situation, your providers, and current regulations. Consult a qualified professional before making financial decisions.

Health calculators

Health and fitness calculators — BMI, calories, body fat, heart rate, pregnancy, and similar tools — do not provide medical diagnosis or treatment. They use general population formulas and can't account for your individual health conditions. For health decisions, talk to a doctor or other qualified healthcare provider.

Construction calculators

Construction calculators provide material and cost estimates. They don't replace building codes, manufacturer requirements, engineering, safety checks, or the advice of qualified professionals where those are needed. Always verify quantities and specifications before ordering materials or starting work.

Verify important results

For anything that matters — a mortgage application, a medical question, a building project — independently verify the numbers with an authoritative source or a qualified professional before acting on them.

This site-wide disclaimer supplements the calculator-specific disclaimers shown on each calculator page. Where both apply, both do.
