What is a Golf Handicap Calculator?
A Golf Handicap Calculator is a free tool that helps golfers determine their handicap index based on recent scores and course difficulty ratings. It uses the official USGA handicap system to provide accurate handicap calculations for tournament play and casual golf.
This calculator works for:
- Tournament preparation - Calculate handicap for competitive play
- Course handicapping - Determine strokes received on different courses
- Performance tracking - Monitor improvement over time
- Fair competition - Level the playing field for different skill levels
How Golf Handicap Calculator Works
The calculation uses the USGA Handicap System formula:
Then:
Where:
- Score = Your adjusted gross score for the round
- Course Rating = Expected score for a scratch golfer
- Slope Rating = Relative difficulty for average golfers
- 113 = Standard slope rating for average difficulty

Frequently Asked Questions (FAQ)
Q: What is a golf handicap?
A: A golf handicap is a numerical measure of a golfer's potential ability, calculated from their recent scores. It allows golfers of different skill levels to compete fairly by adjusting the number of strokes given or taken.
Q: How many scores do I need to calculate a handicap?
A: You need at least 5 scores to calculate a basic handicap, but the USGA recommends using 20 scores for the most accurate handicap index. The system uses your best 10 differentials from the most recent 20 scores.
Q: What is a course rating and slope rating?
A: Course rating is the expected score for a scratch golfer under normal conditions. Slope rating measures how much harder the course plays for average golfers compared to scratch golfers. Both are provided by the course and are essential for accurate handicap calculation.
Q: How often should I update my handicap?
A: You should update your handicap after every round you play, but the index is typically recalculated weekly or monthly depending on how often you play. Most golf associations require a minimum number of recent scores for an official handicap.
Q: What does my handicap number mean?
A: Your handicap represents the number of strokes you can expect to take over par on an average course. For example, a 15-handicap golfer would be expected to shoot 87 on a par 72 course (72 + 15 = 87).
Q: Can I have a negative handicap?
A: Yes, a negative handicap (also called a plus handicap) indicates you consistently shoot below par. For example, a -5 handicap means you typically shoot 5 strokes under par. This is rare and usually only achieved by professional or elite amateur golfers.
