EFG (Effective Field Goal %) Calculator

What is Effective Field Goal Percentage (EFG) and Why Should You Care?

Ever wonder if there's a better way to measure a basketball player's shooting efficiency than just looking at their traditional field goal percentage (FG%)? Enter Effective Field Goal Percentage (EFG)! This stat takes into account not just the number of shots made, but also the added value of 3-point shots compared to 2-point shots. Essentially, it gives a more accurate picture of a player's scoring prowess.

So why should you care? Well, EFG can help you analyze player performance more effectively. For fans and analysts, it provides a deeper understanding of a player's shooting efficiency. For coaches and players, it offers insights into areas for improvement or strengths to capitalize on. In a nutshell, EFG is a smarter metric for anyone serious about basketball analytics.

How to Calculate Effective Field Goal Percentage (EFG)

Calculating EFG is simpler than you might think. Here's the formula you'll need:

\[ EFG = \frac{(\text{2-Point Field Goals Made} + 1.5 * \text{3-Point Field Goals Made})}{\text{Field Goal Attempts}} * 100 \]

Where:

  • 2-Point Field Goals Made: The number of 2-point shots made by the player.
  • 3-Point Field Goals Made: The number of 3-point shots made by the player.
  • Field Goal Attempts: The total number of shots the player has attempted.

Simple, right? Let's see this formula in action.

Calculation Example

Let's dive into an example to make this more concrete. Imagine a player who has made 50 2-point field goals and 30 3-point field goals. Suppose this player has attempted a total of 220 shots.

Plugging these numbers into our formula:

\[ EFG = \frac{(50 + 1.5 * 30)}{220} * 100 \]

First, calculate the weighted field goals:

\[ 50 + 1.5 * 30 = 50 + 45 = 95 \]

Then, divide by the total number of attempts:

\[ \frac{95}{220} = 0.4318 \]

Finally, multiply by 100 to get the percentage:

\[ 0.4318 * 100 = 43.18% \]

So, the Effective Field Goal Percentage (EFG) for this player is 43.18%. Not too shabby!

Why EFG is More Insightful than FG%

You might be wondering, why go through this trouble when traditional FG% is so straightforward? Traditional FG% simply considers the number of shots made over the total shots taken, without factoring in the extra value of a 3-point shot. EFG%, on the other hand, gives a weighted measure that better reflects shooting efficiency by considering the 1.5x value of 3-point shots. So, if you want a true reflection of shooting performance, EFG% is the way to go.

Factors Affecting EFG%

Several elements can influence a player's EFG%, such as:

  • Shooting Ability: Natural talent or developed skill in shooting.
  • Shot Selection: Choosing high-percentage shots.
  • Defensive Pressure: How well the opposing team defends.
  • Offensive System: The team’s strategy and playmaking.

In essence, a player's EFG% isn't just about their shooting; it's about the context in which they shoot.

EFG% for Teams

Did you know? EFG% can also be applied to entire teams to gauge their shooting efficiency. If a team collectively has a high EFG%, it indicates good shot selection and effective offensive strategies.


Boom! Now you're ready to evaluate players like a pro. So next time you watch a game or dive into stats, you'll have a richer understanding of what makes a player or team truly effective on the court. Game on!
