What is Effective Field Goal Percentage?

Effective Field Goal Percentage (eFG%) is an advanced basketball statistic that measures shooting efficiency while accounting for the fact that three-point field goals are worth 50% more than two-point field goals. It provides a more accurate picture of a player's shooting value than traditional field goal percentage.

Regular FG% treats all made shots equally: going 5-for-10 on two-pointers (10 points) looks the same as going 5-for-10 on three-pointers (15 points)—both show 50% FG%. eFG% corrects this by giving three-pointers a 1.5× weight, so the three-point shooter's eFG% becomes 75% while the two-point shooter stays at 50%.

This metric is crucial in modern basketball where three-point shooting has become increasingly important. NBA teams and analysts use eFG% to evaluate shooting performance, compare players, and inform strategic decisions about shot selection. A league-average eFG% in the NBA is typically around 53-54%.

How eFG% is Calculated

The Formula

eFG% = (FGM + 0.5 × 3PM) / FGA × 100
• FGM = Field Goals Made (all shots made)
• 3PM = Three-Pointers Made
• FGA = Field Goals Attempted (all shots)

Why 0.5?

The 0.5 multiplier represents the 50% bonus value of a three-pointer compared to a two-pointer. Each made three-pointer counts as 1.5 made shots in the calculation:

• Two-pointer value: 2 points2 / 2 = 1.0×
• Three-pointer value: 3 points3 / 2 = 1.5×
So we add the extra 0.5 to each three-pointer made: 1.0 (for making the shot) + 0.5 (bonus) = 1.5

Example Calculation

A player shoots 12-for-20 with 5 three-pointers made:

Given:
FGM = 12 (total shots made)
FGA = 20 (total shots attempted)
3PM = 5 (three-pointers made)
This means 7 two-pointers made (12 - 5 = 7)
Points:
(7 × 2) + (5 × 3) = 14 + 15 = 29 points
Regular FG%:
12 / 20 = 0.600 = 60.0%
eFG%:
(12 + 0.5 × 5) / 20
= (12 + 2.5) / 20
= 14.5 / 20 = 0.725 = 72.5%
Analysis:

eFG% = 72.5% (Elite efficiency!)

The +12.5% boost from 60.0% FG% to 72.5% eFG% reflects the true value of making 5 three-pointers. This player scored 29 points on 20 shots (1.45 points per attempt), which eFG% captures better than raw FG%.

Frequently Asked Questions

Is eFG% better than regular FG%?

Yes, for evaluating shooting efficiency. eFG% accounts for three-pointers being worth more, giving a truer picture of scoring value. A player shooting 45% on all threes (1.35 points/shot) is more efficient than one shooting 50% on all twos (1.00 points/shot), and eFG% reflects this.

Does eFG% include free throws?

No, eFG% only measures field goal shooting. For a complete shooting metric that includes free throws, use True Shooting Percentage (TS%), which accounts for points from FGs, 3PTs, and FTs.

What's a good eFG% in the NBA?

NBA league average is ~53-54%. Above 57% is very good, 60%+ is elite. The best shooters and interior scorers reach 62-65%. Centers who only take layups/dunks can exceed 70%, while high-volume three-point shooters at 55%+ are elite.

Can eFG% be over 100%?

No. The maximum eFG% is 150%, achieved by making 100% of attempts with all shots being three-pointers: (FGM + 0.5×FGM)/FGA = 1.5×100% = 150%. In practice, elite players rarely exceed 70%.

Why not just use points per shot?

eFG% is used because it's scaled similarly to regular FG%, making it intuitive for comparison. Both range from 0-100%+ with ~50% being average. Points per shot (0-3 scale) works too but is less familiar to basketball audiences.

Does shot difficulty matter for eFG%?

eFG% doesn't account for shot difficulty, defensive pressure, or shot creation ability. A player hitting wide-open threes has the same eFG% as one hitting contested shots. Context matters when comparing players with similar eFG%.

How does volume affect eFG%?

Higher volume (more shots) usually decreases eFG% because players take more difficult shots. A role player shooting 5 open threes per game at 65% eFG% isn't comparable to a star taking 20 contested shots at 55% eFG%. Elite scorers maintain high eFG% despite volume.

Should teams only take threes and layups?

This is the 'Moreyball' strategy popularized by analytics. Threes (3 points) and layups (high % twos) have better expected value than mid-range shots. However, some mid-range shots are still valuable for spacing, clock management, and exploiting defensive weaknesses.
