How eFG Calculator Works?

The eFG Calculator measures basketball shooting efficiency by adjusting field goal percentage to give additional value to three-point baskets. A made two-point shot counts as one made field goal, while a made three-point shot contributes an extra half field goal because it scores 50% more points than a two-point shot.

eFG%=FGM+0.5×3PMFGA×100

In this formula, FGM is field goals made, 3PM is three-pointers made, and FGA is field goal attempts. The calculator accepts the total number of field goals made, the number of those makes that were three-pointers, and total field goal attempts.

For example, with 8 field goals made, 3 three-pointers made, and 15 field goal attempts:

eFG%=8+(0.5×3)15×100=63.33%

The resulting effective field goal percentage is 63.33%, showing that the player's or team's scoring value per field goal attempt is higher than their ordinary field goal percentage would suggest because three-point makes receive additional credit.

Practical Use Cases

Basketball analysts can use eFG% to compare shooting efficiency across players or teams while accounting for differences in three-point volume. It is especially useful when evaluating scorers whose standard field goal percentages may not fully reflect the value of their outside shooting.

Coaches can review eFG% for individual games, lineups, or full seasons to assess offensive shot-making and identify whether a team is benefiting from efficient three-point production.

Players can use the calculator to evaluate their own shooting performances and understand how making more three-pointers affects overall efficiency, even when their regular field goal percentage remains similar.

Basketball fans and fantasy sports users can use eFG% to compare offensive contributors more fairly than by field goal percentage alone, particularly when comparing players with different shot distributions.

Accuracy and Limitations

The calculator produces an arithmetic eFG percentage from the entered whole-number totals and is accurate when field goals made, three-pointers made, and field goal attempts are recorded correctly. Field goals made should not exceed field goal attempts, three-pointers made should not exceed field goals made, and field goal attempts must be at least 1. eFG% does not account for free throws, turnovers, assists, shot difficulty, opponent defense, game situation, or the difference between two-point shot locations, so it should be used as a shooting-efficiency measure rather than a complete evaluation of offensive performance.

Quick Examples

Example #1: Efficient Team Shooting

Evaluate a team's effective field goal percentage from a typical game shooting line.

Example #2: Player Shooting Performance

Measure an individual player's shooting efficiency when converting several three-point attempts.

Example #3: Low-Volume Three-Point Example

Assess effective shooting efficiency for a player or team taking mostly two-point shots.

Frequently Asked Questions

Effective field goal percentage measures shooting efficiency while recognizing that a three-point basket is worth more than a two-point basket. A higher percentage indicates more efficient scoring from field-goal attempts.

Field goal percentage treats all made baskets equally, while effective field goal percentage gives additional credit for made three-pointers. This makes it more informative when comparing players or teams with different shot selections.

A strong value depends on the league, era, position, and level of competition. In general, percentages above the league average indicate relatively efficient shooting.

Yes. Because made three-pointers receive extra value, effective field goal percentage can be higher than 50% and may exceed 100% in unusual statistical samples.

Yes, but comparisons are most useful when players have similar roles, shot volumes, and competition. The statistic does not account for free throws, turnovers, offensive rebounds, or overall scoring responsibility.
