A golf handicap is a number that represents how well you play relative to the course's difficulty. It exists so golfers of different skill levels can compete fairly against each other.
If you've ever heard someone say "I'm a 15 handicap" or seen tournament results adjusted for handicap, this is what they're talking about.
What the Number Means
A handicap index is a number, usually between 0 and 54, that estimates how many strokes above par you typically shoot, adjusted for course difficulty.
A scratch golfer (handicap 0) plays roughly at par. A 20-handicap golfer typically shoots about 20 over par. A lower number means a better player.
The handicap isn't your average score. It's based on your best recent rounds, not all of them. The idea is to reflect your potential, not your worst days.

How It's Calculated (Plain Language)
The official system is called the World Handicap System (WHS), adopted globally since 2020. Here's the simplified version:
- You play rounds and post your scores
- Each score is converted to a "Score Differential," which adjusts for the difficulty of the course you played (using Course Rating and Slope Rating)
- Your handicap index is based on the best 8 of your last 20 differentials
- The index updates automatically as you post more rounds
You don't need to do the math yourself. The system does it. What matters is that you post your scores consistently.

How to Get a Handicap
You need two things: a way to post scores, and enough rounds to generate an index.
Through your golf club. If you belong to a club (or can join one as a social member), most clubs manage handicaps through their own system and sync with the national golf association. This is the most common route. Ask your club's pro shop or membership office how to get set up.
Through the NGAP (no club needed). If you don't belong to a club, the National Golf Association of the Philippines (NGAP) offers individual WHS membership. You can sign up directly through their individual membership page for a one-time fee of ₱500. Once confirmed, you get access to the same WHS features that club-affiliated members use, including the ability to post scores and maintain an official handicap index.
The Back Nine is not affiliated with the NGAP. We're linking to their page because it's the most accessible path to an official handicap for golfers who aren't members of a club.
To establish an index under the WHS, you need a minimum of 54 holes of posted scores (typically 3 rounds of 18 holes). Your index becomes more accurate as you post more rounds.
How You Use It in a Round
Before you play, your handicap index is converted to a "Course Handicap" for the specific course and tees you're playing. This accounts for the course's difficulty.
For example, a 15-handicap index might translate to a 17-course handicap at a harder course, or a 13-course handicap at an easier one.
In a handicap-adjusted competition, your course handicap is subtracted from your gross score to give your net score. That net score is what you compete on.
Gross vs. Net Score
Different gross scores, same net score. That's the point of a handicap.
What Is System 36
System 36 is a simplified handicap method widely used in the Philippines for casual tournaments and company outings. It's not part of the official WHS, but it's deeply embedded in Philippine golf culture.
Here's how it works:
- Every player starts with a handicap of 36
- You play 18 holes and record your gross score
- Subtract par (usually 72) from your gross score. The difference is how many strokes over par you played
- Your System 36 handicap for the next round is calculated based on that performance
- The system adjusts after each round, moving your handicap up or down
The formula varies slightly depending on who's running the tournament, but the core idea is the same: it gives every player a working handicap quickly, without requiring 20 rounds of history.

System 36 vs. WHS
System 36 is fast and practical. It gives everyone a number in one round. But it's less accurate than the WHS because it uses fewer data points and doesn't account for course difficulty.
For casual events and corporate tournaments, System 36 works fine. For official competitions and tracking your long-term progress, the WHS is the standard.
Many Filipino golfers use both: System 36 for weekly outings and WHS for their real index.
Where to Start Posting Scores
The first step is simply playing and keeping an honest scorecard. If you're looking for courses to get your first rounds in, you can browse fees and locations on our course directory.
Your handicap will only be as accurate as the scores you post. Count every stroke, every penalty, every round. The number is for you.
