eFG Calculator (Basketball)

Enter your field goals made (2-point and 3-point) and total field goal attempts to calculate your Effective Field Goal Percentage (eFG%). This basketball stat adjusts for the extra value of three-pointers, giving a truer picture of shooting efficiency than standard FG% alone.

Total number of 2-point field goals successfully made.

Total number of 3-point field goals successfully made.

Total number of field goal attempts (all 2-point and 3-point shots attempted).

Frequently Asked Questions

What is Effective Field Goal Percentage (eFG%)?

Effective Field Goal Percentage (eFG%) is a basketball statistic that adjusts a player's or team's shooting percentage to account for the extra value of 3-point shots. Because a made 3-pointer is worth 50% more than a made 2-pointer, eFG% gives 3-pointers additional weight in the formula, providing a more accurate measure of shooting efficiency than standard FG%.

How do I calculate Effective Field Goal Percentage?

The eFG% formula is: eFG% = (All FG Made + 0.5 × 3-Point FG Made) / Total FG Attempts. You add half of your 3-point makes to your total field goals made, then divide by total attempts. This gives the 0.5 bonus credit to each 3-pointer made, reflecting its extra scoring value.

What is the difference between eFG% and standard FG%?

Standard FG% treats every made shot the same regardless of whether it was a 2-pointer or 3-pointer. eFG% corrects this by applying a 1.5× multiplier to 3-point makes in the numerator. A player who makes lots of 3-pointers may have a lower standard FG% but a higher eFG%, which more truthfully reflects their scoring contribution.

What is considered a good Effective Field Goal Percentage?

In the NBA, an eFG% above 55% is generally considered very good, and elite shooters or efficient teams often post eFG% values above 58–60%. The league average typically sits around 52–54%. For youth or amateur basketball, any eFG% above 50% indicates solid shooting efficiency.

Can eFG% be used for an entire team, not just individual players?

Yes. eFG% works equally well as a team-level metric. Simply sum up all 2-point FGM, 3-point FGM, and total FGA across the team for a given game or season, then apply the same formula. Teams with higher eFG% consistently tend to win more games, making it a strong predictor of team success.

Why does the eFG% formula multiply 3-point makes by 0.5?

The 0.5 multiplier gives 3-pointers a 50% bonus credit in the numerator. Since a 3-point shot is worth 1.5 times a 2-point shot, adding 0.5 to each 3-pointer made (rather than 1) accounts for this extra value without double-counting the made field goal already included in the total. The result scales eFG% comparably to standard FG% but adjusted for shot quality.

Does eFG% account for free throws?

No. eFG% only considers field goal attempts — it does not include free throws. If you want a metric that also factors in free throw efficiency and turnovers, you would use True Shooting Percentage (TS%), which is another advanced basketball statistic. eFG% is specifically focused on shot-selection and shooting efficiency from the field.

Can I use this calculator for a full season's stats?

Absolutely. Just enter the cumulative season totals for 2-point FGM, 3-point FGM, and total FGA across all games played. The formula works the same way whether you're analyzing a single game or an entire season, making it useful for evaluating long-term shooting trends.
