What’s your handicap?

We golfers treat this question with great seriousness but we often misinterpret what the answer means.

Let’s get a few things straight.

It’s Not Your Scoring Average

Having a handicap index of 10 doesn’t mean you average 10-over par for 18 holes. The calculations are more nuanced than that. We’ll get into some of the basics below, but for now, think of your handicap as a measure of what you’re capable of shooting, not what you’re expected to shoot in any given round. Your average score is higher than your handicap.

It Requires Some Number Crunching

But you don’t have to do the math. There’s something called the GHIN system — a proprietary platform created by the USGA — that will do it for you. Your only task is to enter your scores.

How It’s Calculated

You can establish a handicap with as few as three 18-hole scores (with such a small sample size, a modified formula is used). Once you’ve entered 20 scores, your handicap index is derived by taking the average of your 8 best score differentials — that is, your 8 best scores as measured in relation to the difficulty of the course (which, in turn, is measured by the Course Rating and Slope Rating).

It’s Not the Same as Your Course Index

Your handicap index is one thing. It doesn’t tell you how many strokes you’ll be getting in a round. That number is called your course handicap, which is your handicap index adjusted (by way of the Slope Rating) to the difficulty of the course you’re playing.

How Often You Should Shoot Your Handicap

It’s not your average score. It’s a gauge of your potential. So, how often should you reach it? Different stat gurus have arrived at different answers. But there is general agreement that you should shoot your handicap around 20 to 25 percent of the time. Meaning, once in every 4 to 5 rounds.

And If You Don’t?

Are you sure you’ve been keeping tallies and entering every score? You might be either a sandbagger (someone who is better than their handicap) or a vanity capper (someone too proud to accept reality).
