What is a golf handicap?

A golf handicap is a numerical measure of a golfer’s potential ability. It allows players of all skill levels to compete fairly. Under WHS (world handicap system), handicaps are calculated based on the best 8 of your last 20 rounds, adjusting for the difficulty of the course.

  • Lower handicap → more skilled golfer & less strokes given in competition
  • Higher handicap → less skilled golfer & more strokes given in competition

How the WHS (World Handicap System) Works

The WHS is used worldwide, including in the UK, Europe, Australia, and the USA. It combines the best elements of the old USGA and CONGU systems. Formula for Handicap Differential:

(Adjusted Gross Score – Course Rating) × 113 ÷ Slope Rating

Your Handicap Index is the average of the lowest 8 differentials from your last 20 rounds.

The Course Handicap adjusts this index to the difficulty of the course and tees you are playing.

Step by Step Example for Golf Handicap Calculator

Let’s say:

  • Handicap Index: 15.2
  • Course Rating: 71.4
  • Slope Rating: 128
  • Par: 72

Course Handicap = (15.2 × 128 ÷ 113) → 17 strokes

So you’ll receive 17 extra shots during your round.

Tips on Lowering Your Handicap

Improving your handicap takes a mix of practice and smart course management:

  • Focus on short game and putting – they make up the majority of strokes.
  • Track your game with apps to spot weaknesses.
  • Play different courses to gain experience in varied conditions.
  • Stay consistent with pre-shot routines.

The History of the Golf Handicap

The concept of the golf handicap dates back to the late 17th century in Scotland, the birthplace of the modern game. Early systems were informal, with stronger players granting weaker ones a set number of strokes to even the match. By the mid-1800s, golf clubs began recording members’ scores and creating standardised allowances. One of the earliest documented systems appeared in 1893, when the Ladies’ Golf Union in the UK introduced a national handicapping method. Over the 20th century, different regions developed their own formulas – such as the CONGU system in the UK and the USGA Handicap System in America – each calculating handicaps in slightly different ways. This made international competition tricky, as a golfer’s handicap could vary depending on where they played. In 2020, the World Handicap System (WHS) was launched to unify these approaches. Managed jointly by The R&A and the USGA, WHS uses a consistent formula based on recent performance, course difficulty, and slope rating. Today, millions of golfers worldwide rely on handicaps not only for fair competition, but also as a benchmark to track their own improvement over time – continuing a tradition that’s been part of golf for more than 300 years.
