Handicap Calculation Formula

The formula to calculate the Golf Handicap Index is:

Handicap Index = (Average of Best Scores × 113) / Slope Rating

Where:

  • Average of Best Scores is the average of the lowest 10 scores out of the last 20 rounds played.
  • The Slope Rating is a measure of the difficulty of a golf course for a bogey golfer compared to a par golfer.
  • The Course Rating is the expected score for a scratch golfer on that course.

What is a Golf Handicap?

A golf handicap is a numerical measure of a golfer's potential ability. It is used to adjust a player's score to allow fair competition against players of different skill levels. The lower the handicap, the better the player. A golfer’s handicap is calculated based on recent scores relative to the course rating and slope, which accounts for the difficulty of a golf course.

Why Use a Golf Handicap Calculator?

How to Use the Golf Handicap Calculator

  1. Step 1: Input your score for a round of golf.
  2. Step 2: Enter the Course Rating (par of the course).
  3. Step 3: Enter the Slope Rating of the course (typically between 55 and 155, with 113 being average).
  4. Step 4: Repeat this process for multiple rounds (at least 3, ideally 20).
  5. Step 5: The calculator will compute your handicap index.

Golf Handicap Formula

Handicap Differential for a round is calculated using:

Handicap Differential = (Score - Course Rating) × 113 / Slope Rating

Then, your Handicap Index is the average of the lowest Handicap Differentials from your most recent scores (e.g., lowest 8 of your last 20 rounds), multiplied by 0.96.

Example Calculation:

Score: 85
Course Rating: 72.0
Slope Rating: 120

Handicap Differential = (85 - 72.0) × 113 / 120 = 13 × 113 / 120 ≈ 12.24

How Handicap Index Becomes Course Handicap

Your Handicap Index is used to calculate your Course Handicap for a specific course using the formula:

Course Handicap = Handicap Index × (Slope Rating / 113)

This adjusts your handicap for the course’s difficulty.
