HOW IS A GOLF HANDICAP CALCULATEDPlay

Golf Handicap: How it's calculated

Your handicap is calculated by using well-known, public information regarding the difficulty of different golf courses throughout the world. Our calculation of your handicap uses your score from 9 or 18 holes on a golf course, the Course Rating™ for the tees at the course you’ve played, and Slope Rating®  for the tees at the course you’ve played. These ratings are often included on your scorecard or on a golf course’s website and our App also contains a database of such information.

The 18Birdies App will calculate your handicap using the following formula:

Step 1:  Handicap = (Score - Course Rating™ x (113/SLOPE®)

Step 2: Calculation of your average best Step 1 scores using the formula set out in the below table:

Example:  Let’s say you play 2 rounds of Golf at Pebble Beach on Monday and Tuesday, a round at Spanish Bay on Wednesday, then head over to Spyglass Hill on Thursday to play 36 holes, and you finish off this once in a lifetime week of golf at Poppy Hills for 18 holes.

Your Step 1 scores for these rounds would be as follows:

Pebble Beach score of 78:    (78 - 75.5) X (113/145) = 1.95

Pebble Beach score of 82: (82 - 75.5) X (113/145) = 5.07

Spanish Bay score of 76: (76 - 74.0) X (113/140) = 1.61

Spyglass Hill score of 80: (80 - 75.5) X (113/144) = 3.53

Spyglass Hill score of 77: (77 - 75.5) X (113/144) = 1.18

Poppy Hills score of 79: (79 - 74.4) X (113/144) = 3.61

Step 2: Referring to the chart above, we would take the lowest Step 1 scores from only two rounds (Spanish Bay and Spyglass Hill) and average them together like so:  

(1.18 + 1.61) / 2 = 1.4

Your handicap would be 1.4 with the 6 rounds entered. You might be headed to the tour here soon if you keep using the 18Birdies App.  Nice work.

How many rounds should I enter before my handicap starts to become precise?

Your 18Birdies Handicap will use your latest 20 eligible rounds, and of those 20 rounds will use the lowest 8 rounds towards the calculation.  We suggest entering at least 10 of your latest rounds to start to see a more precise representation of your 18Birdies Handicap.

What if I play only 9 holes? Will the App use my 9-hole scores to calculate my handicap?

Yes.  In contrast to some other handicap products on the market, the 18Birdies App will calculate a handicap based on a 9-hole round by doubling the 9-hole round score to determine an 18-hole score that will count towards your handicap.

Every time you enter a score for a 9-hole or 18-hole round of golf into 18Birdies, you will get an automatic update to your handicap.

Do I have to record every round I play towards my 18Birdies Handicap?

It’s entirely up to you to determine what rounds you want to include or exclude towards your handicap. Although ideally to get the most accurate representation of your game you would want to enter all scores you play.

Are rounds from Par 3 courses included?

No.  When entering scores from Par 3 courses / executive courses, or any course with an 18-hole par of less than 69, these scores will not be counted towards your handicap.  If you play an individual 9 hole round with par of 34 or less (that isn’t part of a full 18-hole round with par of 69 or higher), that 9 hole round won’t be included in your handicap calculation.

What is the maximum handicap? Minimum?

There is no maximum handicap when you use the 18Birdies App.  There is also no set minimum handicap, it is 100% based on the scores you enter so it can be as high or low as your scores determine.

Am I able to get a handicap if I live outside the United States? 

Yes, although depending on where you live, some international courses may not be eligible to count towards your handicap.

Can I enter a score from my old scorecards to get a handicap?

Yes! Absolutely.
