# What is your Handicap

And more importantly how is handicap index determined

If a golfer were to shoot 20 consecutive rounds of even par on a par 72 golf course with a course rating of 69.6 and a slope of 123 would his handicap index be  0?

The answer is no, his handicap index would be 2.1.

So, what about if another golfer who also played 20 round of golf on the same course and shot 1o rounds at even par, and the remaining 10 rounds were scattered between 73 and 82.  What would his handicap index be?

It would also be 2.1.

Why is that you ask?  Well, it’s because for handicap purposes the accepted practice is to use the best 10 out of your last 20 rounds for handicap calculation purposes and the best 10 rounds out of their last 20 were the same for both golfers.

So if the 10 scores used for handicap calculation purposes  were all even par why is the handicap index not 0?

The answer is that a formula laid out the Golf Canada is applied and that formula stipulates that the course rating and not the par for the course be used to calculate the handicap index.  In the case of the above two examples it would work like this:

The differential between the score shot and the course rating is calculated for each round used for handicap purposes.  In this case the differential for each round was the gross score minus the course rating (72-69.6=2.4) as the scores were all the same.

In real life the calculation would be done for each round, they would then be added up and divided by 10 to obtain an average.  That number is then multiplied by 113 which is the slope rating assigned to golf courses that are of average difficulty (113 x 2.4=271.2)  This product is then divided by the slope rating for the course in question 271.2/123=2.2

The last step in applying the formula is to multiply 2.2 by .96 which yields a handicap index of 2.1

The good thing for golfers is that you don’t need to do any of these calculations.  All you need to do is to enter your score into the computer and the handicap software looks after the rest.

So, if your handicap index is 2.1, the average of your best 10  out of your last  20 games playing off the white and red tees at The  Wildewood Club should be 72.

Great blog site Menno!

As for this article, you provide an informative overview of the handicap calculation. Thanks!

Thanks Manny. The handicap system actually flatters golfers, largely based on the fact that it reflects the best 10 scores out of the last 20. If it was based on our last 10 scores, period, and not throwing out the higher rounds most of us would have higher handicaps.
