Fill in the fields above, then press Calculate.

A golf handicap calculator computes your USGA Handicap Index from recent scores, letting you track improvement and compete fairly across different courses.

Enter your recent golf scores as comma-separated values (at least 5, ideally 20), along with the course rating and slope rating. The calculator computes your handicap index using the USGA differential method.

Examples

20 scores averaging ~89

With course rating 72.0 and slope 113, differentials average around 17.0 for the best 8, yielding a handicap index of approximately 17.0.

Frequently Asked Questions

How many scores do I need?
A minimum of 5 scores is required. The USGA uses up to 20 of your most recent scores. With 20 scores, the best 8 differentials are used for the calculation.
What are course rating and slope rating?
Course rating is the expected score for a scratch golfer on that course. Slope rating (55-155, with 113 as standard) measures the relative difficulty for a bogey golfer versus a scratch golfer. Both are printed on your scorecard.

Quick Tips

  • •Enter at least 20 scores for the most accurate handicap; fewer scores use fewer differentials and may skew results.
  • •Update your course rating and slope rating each time you play a different course.
  • •Track your handicap trend over time to measure the effectiveness of your practice routine.
