Golf Handicap Calculator

About Golf Handicap Calculator

Golf Handicap Calculator computes Score Differential, Handicap Index, Course Handicap, and Playing Handicap using the World Handicap System formulas.

Use this golf handicap calculator to see a round's Score Differential the moment you type in a score, then your Handicap Index, Course Handicap, and Playing Handicap for the tee you entered - with the formulas shown on screen so you can check the math.

HANDICAP
- Enter adjusted gross score, course rating, slope rating, and par
- See this round's Score Differential update live as you type
- See Handicap Index, Course Handicap, and Playing Handicap computed from your saved scoring record and the entered tee
- Opens with a standard par-72 tee prefilled, so a single score produces a result with no setup
- Save the computed round to your scoring record; saving the first round starts the record, and later rounds unlock with a short rewarded ad

SCORES
- View your Handicap Index and how many rounds it was built from
- See which of your saved rounds are the ones actually counted toward the current index
- Add a round directly, or delete any saved round
- Handicap Index and adding a round are always available; viewing the round-by-round history unlocks with a short rewarded ad

COURSES
- Save a course and tee as a named preset: course rating, slope rating, and par
- Load a saved preset onto the Handicap tab in one tap
- Delete any saved preset
- The first saved course needs no ad; saving more unlocks with a short rewarded ad

WHAT IT CALCULATES
This app implements the WHS Rule 5.1 Score Differential formula, the full Rule 5.2a table for a Handicap Index built from fewer than 20 scores (not just the "best 8 of 20" shorthand), and the Rule 6.1/6.2 Course Handicap and Playing Handicap formulas including the Course Rating minus par term added in the January 2024 revision.

This is an unofficial calculator, not an official handicap of record. An official Handicap Index is issued only by an authorised golf association through its licensed handicap system, and only scores posted through an authorised system count toward one. Figures shown here are estimates for personal, informational use only.

BUILT FOR THE COURSE
- Fast entry with minimal taps
- Works offline at the course
- No account required
- Your scoring record and saved courses stay on your device

This app is ad-supported. Calculating a differential and adding a round are always available; saving beyond the first round or course, and viewing your round history, unlocks with a short rewarded ad.
