About UtilityInstant and our methods
UtilityInstant offers free tools for calculations, conversions and comparisons, without an account. We aim to show both the result and the assumptions behind it so you can judge whether they fit your situation.
How results are calculated
Each tool applies the formulas and options described on its page. Simulations use your assumptions: they do not predict interest rates, investment returns or actual travel times. External references are linked where applicable. Automated tests check calculations and boundary cases; they are not certification or independent professional review.
Use and limitations
Results are estimates or transformations of your input. Health tools do not diagnose, finance tools do not replace a contract, and logistics tools do not certify regulatory compliance. Check units, rounding and assumptions before using a result to make a decision.
Report an error or contact us
Email the project contact with the tool, language, expected result and what happened. Use fictional data to reproduce the issue; do not send passwords, private documents or medical information. We do not provide emergency services or individual professional advice.
Privacy and funding
The project plans to fund free access through advertising. Ads are labelled and do not change calculations. See the privacy policy for local storage, analytics and the external services used by the route map.
