Why We Built This

Golf handicap calculators online range from confusing to outdated to hidden behind paywalls. When the World Handicap System launched, it unified the rules globally — but finding a clean, reliable tool to actually run the calculation was surprisingly hard.

Handicap.golf exists to fix that. One tool, the correct WHS formula, free to use, with no registration required for the basic calculator. We also provide plain-English guides explaining exactly how the system works — because understanding your handicap makes the game more enjoyable.

Our Commitment to Accuracy

Every calculation on this site uses the publicly documented World Handicap System formula. We are not affiliated with the R&A, USGA, England Golf, Scottish Golf or any national golf union. Our tool provides estimates for guidance — your official Handicap Index must be issued and maintained by a recognised golf club or national governing body.

We update our formulas whenever WHS guidelines change. Our 2026 calculations reflect the latest England Golf and R&A guidance.

Free to Use, Supported by Ads

Handicap.golf is completely free to use. We keep the lights on through Google AdSense advertising. We do not sell your data, show intrusive pop-ups, or put any calculations behind a paywall. The ads are clearly labelled and relevant to golfers.
