How Is My Golf Handicap Calculated?

How Is My Golf Handicap Calculated?

We have had many Grinters asking the same questions over a long period of time. For example, “Why is my Golf Handicap so low if my Score Average is around 88?”. So, here you go, this is short and sweet what you need to know about the Handicap System.

To begin, you should know that the Handicap Index is intended to represent a golfer’s potential ability.  Therefore, it is not calculated using the Score Average. The Handicap is calculated using the Handicap Differentials of your best rounds.

The Handicap Differential is:

(ESC Score – Course Rating ) *113 / Slope Rating

So, the more Scores you have uploaded to your TheGrint Account, the more accurate your Handicap Index will be. And once you have 20 or more Scores uploaded, the Handicap will use only the Lowest 10 Handicap Differentials out of your last 20 Scores you uploaded. After those Differentials are calculated you average them and then Multiply them by 96% (.96)

And there is your Golf Handicap Index!

Just in case you don’t know what ESC is, the USGA establishes a maximum score per Hole, so the Total Score after applying those Maximums is your ESC (at the bottom of the blog we show you the ESC “Equitable Stroke Control” Guidelines).

What if you have less than 20 Rounds uploaded?

Well, the USGA has a Table that shows the amount of Differentials are used depending on the amount of Rounds you have posted (see below):

And how do you know the ESC Score? You have to use the below table to limit the max score allowed per hole.

But remember, we do all those calculations automatically. All you have to do is upload your Scores to your TheGrint Account. We do the rest.

To show you an example, we will use Mr. Bob Grint’s scoring record! The easiest way for you to see the Scores that are being used to calculate your Handicap is to go to the Trends Section on the Website and see the Green Bars (those are the lowest Handicap Differentials out of all of your latest Scores).

This is Bob’s Trends Section:

His Handicap Index is 2.0 (pretty good, right?).

Also, you have the Handicap Card, which highlights the Scores that are taken into consideration towards the Handicap with an asterisk (*); it doesn’t show the Handicap Differential, but it does show the Scores (see below):

At the end, you don’t have to know all this, we do the work for you anyway… so, all you have to do is upload your Scores or send them to us through the SPS Service and we will upload them for you (learn more about the SPS Service here).

Any questions, you can e-mail us to contactus@thegrint.com, we will help you out as fast as we can.

Enjoy your Golf!

    I use the Grint App on my iPhone. Is there a way to enter more information than just the ESC score and post? I would like to also enter in greens in regulation and putts.

    • TheGrinter says:

      Hi Steven, good afternoon. Sure. You can upload your Score, plus Stats and Putts.

      Here are the Steps to upload a Scores plus the meaning of the Abbreviations:

      To upload a Score hole-by-hole using the App, follow these steps:

      1. Login
      2. Select Play (on the Top)
      3. Then select GPS, Track & Play
      4. Then choose the option you prefer to search for the Course you played or going to play.
      5. Then Select the Date, Tees and Stats you want to Track at the bottom. Make sure you select Round = Front 9 or Back 9 if you play 9-holes.
      6. Then swipe the screen to the Left until you get to the 1st Hole.
      7. Tap on the Grey Circle to Add the Score (putts, stats and penalties if you want as well). Then swipe to the Left to continue to the 2nd Hole.

      To upload a Total Score using the App, follow these steps:

      1. Login
      2. Select Play (on the Top)
      3. Tap on Post Total Score
      4. Fill out all the information including your Score
      5. Tap and Hold on “Post”

      These are the Steps to upload the Score and Stats through the Website:

      To upload the Score Hole-by-hole through the Website (computer), as well as the stats, follow these steps:

      1. Login.
      2. Click on Scores (on the Top Menu).
      3. Then click on “Add Score” (on the Right hand side).
      4. Then type the name of the Course, make sure you have the Date when you played, not when you are uploading the Score (this way your Handicap will be more accurate).
      5. Then select a Tee and upload the Score (also the Putts, Stats, and Tee Accuracy if you want on the boxes below). Make sure you select Round: Front 9 or Back 9.
      6. Then click Submit.

      To Track the Putts, Penalties and Fairway Accuracy through the Website (computer):

      1. Login
      2. Click on Scores
      3. Click on Add Score (On the Right hand side).
      4. Fill in all the information (Score, Putts, Penalties and the Fairway Accuracy). At the bottom when you are on the Penalties or Fairway Accuracy boxes, you will see the Legend on what to write depending on what you had on that hole. For example, if you went in the Water on the 2nd Hole, you will type a “w”. If you went in the Water and then the Sand Trap next to the Green you will type “ws”.

      After you submit all the information, Click on Submit at the Bottom.

      To upload a Score through the SPS Service, through the App (Scorecard Picture Service), follow these steps: This is a Pro Feature.

      We will receive your Scorecards and upload your Score as soon as we receive it.

      Click here to see how to write down your Score and Stats when you use the SPS Service.

      The meanings of the Acronyms for the Penalties we have are:

      S = Greenside Sand
      F = Fairway Sand
      W = Water Hazard
      O = Out of Bounds
      D = Drop Shot
      SS means that you hit the Greenside Sand twice.
      FF means that you hit the Fairway Sand twice.
      DD means that you had to drop the ball twice (because of unplayable or anything like that).
      FS means that you hit the Fairway Sand and then the Greenside Bunker.

      OS means that you hit it Out of Bounds and then you hit it into the Greenside Bunker.

      And so forth.

      Let us know if you have any questions.

      Regards,

    I am unable to access my “handicap card”. What do I have to click-on in order to access it?

    Also, if I wish to email a current “handicap card” to a fellow player how do I do it?

  3. Ron Reinders says:

    Great job guys and gals . much appreciated.

  4. Carol says:

    Thanks for the explenation.

  5. Mohammad Az says:

    How can we get other scoring types like stableford? Is there any?

    • TheGrinter says:

      Hi Mohammad, good morning,

      You can use the Games Feature to play Stableford or any other type of Game.

      You would keep your Gross (normal) Score, as well as the Stableford.

      You can read how the Games Feature work on the Blog about the Games Feature.

      Contact us through contactus@thegrint.com if you have any questions.

  6. Kyle Walsdorf says:

    If you are just getting started using the Grint, when do you start to apply your ESC scores if you haven’t established a Handicap Index? Without a Handicap Inex, you can’t calculate your Course Handicap, meaning you can’t figure out your ESC because you don’t know how many strokes you are allowed per hole. Please help!

    • TheGrinter says:

      Hi Kyle – Thanks for your question. It is actually a good one, and that is why we ask for your approximate handicap when you registered. We use that as the starting handicap which we will use for ESC purposes. If you did not enter a starting handicap we assume 36 as default, until you enter your first score.

      We hope that helps. Please email us at contactus@thegrint.com if you have any additional questions.

  7. Scott LaCourde says:

    Is there a way to post combined nine hole scores to make a 18-hole handicap (like a manual entry that we can combine scores and post)? This is how the USGA records scores for handicapping (Section 5-2c and d). Looks like the Grint keeps these separate and posts 9 and 19 hole scores to create individual handicaps. How is that useful, as a 9-hole index is not used for any USGA golf far as I know.

    • TheGrinter says:

      Hi Scott, good morning,

      Thank you for contacting us.

      We apologize for the late response.

      We actually do have the Combined Scores Tool. The Combined tool is available on the Website. Go to Scores, then click on Add Score. Then click on Combined 9 Scores.

      There you will be able to upload the Front 9 and Back 9 for your New Combined 18-hole Score.

      Let us know if you have any questions.

      Regards.
