The eFG calculator will help you find the effective field goal percentage for your performance in a basketball game. Did you or your team score a mix of 3-point and 2-point field goals? The effective field goal percentage considers that the 3-point field goals are more difficult and implements that into the formula.

The metric, effective field goal percentage (or eFG%), is used to rate the performance of basketball players and teams in leagues like the NBA and others around the world. This metric can be for a single game or the whole season by adding the data over the season or a bunch of matches.

It is also helpful to determine a team's performance and is tied to a team's success. Higher eFG% implies the team is highly successful during the match. You can directly enter the data into the calculator or read on to understand how to calculate effective field goal percentage.

## What is efg (effective field goal percentage)?

eFG means the actual percentage of scoring field goals by a player or a team in a single match or season. Considering there are 2-point field goals and 3-point field goals in basketball, the players can score a combination of both. Say, Player A has more 3-point field goals, and Player B has more 2-point field goals. You can estimate the field goal percentage for each type of field goal (FG) using the following equations:

\scriptsize \begin{align*} \text{3-point FG \%} &= \frac{\text{3-point FG}}{\text{3-point FG attempts}} \\ \\ \text{2-point FG \%} &= \frac{\text{2-point FG}}{\text{2-point FG attempts}} \end{align*}

However, they both hold different weightage, values, and difficulty ratings. For instance, a 3-point FG is much harder to score. To consider both types of goals together, you can calculate the effective field goal percentage, which is:

$\quad\scriptsize \text{eFG\%} = \frac{\text{All FG} + 0.5 \times \text{3-point FG}}{\text{FG attempts}}$

where:

• $\small\text{All FG}$ – All field goals scored by the player. It is the sum of 2-point and 3-point field goals scored; and
• $\small\text{FG attempts}$ – Total field goals attempted. It is the sum of 2-point, and 3-point field goals attempted.

The metric for a player would vary depending on the team play and their position. For instance, if a player is more on the offense and plays near the basket, he's more likely to get a higher percentage due to reasonable amounts of dunks, whereas the player away from the basket is more likely to take more 3-point shots which are much more difficult.

## How to calculate effective field goal percentage

To find the effective field goal percentage:

1. Enter the number of 2-point field goals scored.
2. Insert the number of 3-point field goals scored.
3. Fill in the number of 2-point field goals attempts.
4. Enter the number of 3-point field goals attempts.
5. The eFG calculator will return the following output:
• Total field goals scored;
• Total field goal attempts;
• 2-Point field goal percentage;
• 3-Point field goal percentage;
• Effective field goal percentage; and
• Total points scored.

## Example: Using the efg calculator

Estimate the effective field goal percentage for a team whose players have made a total of 300 field goal attempts, scoring 105 2-point field goals and 36 3-point field goals. Take the number of 2-point and 3-point field goal attempts as 245 and 55, respectively.

To find the effective field goal percentage:

1. Enter the number of 2-point field goals as 105.
2. Insert the number of 3-point field goals as 36.
3. Fill in the number of 2-point field goal attempts as 245.
4. Enter the number of 3-point field goal attempts as 55.
5. Using the eFG calculator:

An eFG% of 53 is very good considering the highest eFG% for the NBA 2021-22 season for a team is 56.4%.

## FAQ

### What do you mean by effective field goal percentage?

The effective field goal percentage is a metric used to determine the percentage of field goals scored while considering the difficulty of scoring the 3-point field goals. It is a combined statistic including 2-point and 3-point field goals but with different weightage.

### How do I calculate effective field goal percentage?

To find the effective field goal percentage:

1. Divide the number of 3-point field goals scored by 2.
2. Add the number to the total number of field goals.
3. Divide the sum by total field goal attempts to get the effective field goal percentage.

### What is a good effective field goal percentage?

A good effective field goal percentage varies as per a player's position; a player who plays closer to the basket may score at a rate of about 50% or higher, which is considered a good percentage. However, if a player mostly takes 3-point shots, 40% is still regarded as good given the difficulty of 3-point FG attempts.
