Disclaimer
Every calculator on TeeboxMath is an estimate for your own information. It is not an official Handicap Index, not a course handicap issued by a club, and not a substitute for the scoring record kept by an authorized golf association.
The handicap tools are not affiliated with, endorsed by, or produced by the USGA, The R&A, or GHIN. Those names are used only to say what this site is not, and to describe the published method the arithmetic follows. They are not part of the name or the logo.
Some rules are not applied, because a website does not have the data. The playing conditions calculation is the main one. The official expected-score table for nine-hole rounds is not published, so the nine-hole tool uses an approximation that matches the one numeric example the USGA has printed, and it says so on the page. Soft and hard caps run only if you supply a low index. Committee adjustments are not applied.
Distance charts scale published averages. They are not a launch-monitor fitting. The membership page is arithmetic about green fees and dues. It is not financial advice, and it is not a recommendation to join or leave a club.
Nothing on this site is coaching advice that tells you how to swing, and nothing is medical or injury advice. If a number looks wrong, check the inputs on the scorecard before you trust it. TeeboxMath is operated by Inner North Wealth Pty Ltd (ABN 34 679 895 802), Australia.
