Frequently asked questions
Plain-language answers about when to use the tool, what it does with your inputs, what to double-check, and how privacy works.
When should I use the Golf Handicap Calculator?
Use it when your task matches one of these common needs: Estimate a round score differential from adjusted score, rating, slope, and PCC. Estimate course handicap from Handicap Index and tee ratings. It works best when you already know the values, dates, units, or settings the page asks for.
What is the Golf Handicap Calculator doing with my inputs?
In plain language: Score differential uses (113 / slope rating) x (adjusted gross score - course rating - PCC). Course handicap uses Handicap Index x (slope / 113) + (course rating - par). The examples on the page are there so you can compare your inputs with a filled-out calculation before copying the answer.
What should I double-check before trusting the answer?
This is not an official Handicap Index. Official records may include caps, exceptional-score reductions, 9-hole rules, and committee adjustments. Also check that you used the right unit, date, scale, or mode because small input changes can change the result.
Does the site save what I enter?
No. The calculator runs in your browser tab. Your recent answers stay only on the page while you use it, and they are not sent to a server.
