What Is Effective Field Goal Percentage?

Effective field goal percentage (eFG%) is an advanced basketball metric that adjusts the standard field goal percentage to account for the extra value of three‑point shots. Because a three‑pointer is more difficult to convert than a two‑pointer, eFG% gives additional weight to makes from beyond the arc, offering a more accurate picture of shooting efficiency. The eFG Calculator — a free online Effective Field Goal Percentage Calculator — automates this computation, making it a handy Basketball Shooting Efficiency Calculator for coaches, analysts, and fans who track NBA stats or evaluate team performance.

The Formula Behind eFG%

The calculation is simple:

$$\text{eFG\%} = \frac{\text{Total Field Goals Made} + 0.5 \times \text{Three-Point Field Goals Made}}{\text{Total Field Goal Attempts}} \times 100\%$$

• Total Field Goals Made = number of 2‑point makes + number of 3‑point makes.
• Three-Point Field Goals Made = only the makes from beyond the arc.
• Total Field Goal Attempts = all 2‑point and 3‑point attempts combined.

The 0.5 multiplier reflects that a three‑point shot is worth 50 % more than a two‑point shot, normalizing scoring efficiency across different shot types. Unlike a basic Field Goal Percentage Calculator, this metric rewards players who successfully take the harder shot.

How to Use the eFG Calculator

The tool needs just four numbers:

1. 2‑point field goals made
2. 3‑point field goals made
3. 2‑point field goal attempts
4. 3‑point field goal attempts

After entering them, you get a full breakdown:

• Total field goals made
• Total field goal attempts
• 2‑point field goal percentage
• 3‑point field goal percentage
• Effective field goal percentage (eFG%)
• Total points scored

This Basketball eFG Calculator is especially useful when you need to compare players or teams with different shot distributions.

Worked Example

A team attempts 300 field goals: 245 two‑point attempts and 55 three‑point attempts. They make 105 two‑pointers and 36 three‑pointers.

Metric	Value
Total field goals made	141
Total FG attempts	300
2‑point FG%	42.86 %
3‑point FG%	65.45 %
eFG%	53 %
Total points scored	318

An eFG% of 53 % indicates well‑above‑average efficiency. For perspective, the highest team eFG% in the NBA during the 2021‑22 season was 56.4 % (Utah Jazz).

What Is a Good eFG%?

The threshold depends on a player’s position and shot selection:

• Players who operate near the basket (centers, forwards) often post eFG% of 50 % or higher — that’s considered strong.
• Perimeter‑oriented players who take many three‑pointers are efficient with an eFG% around 40 % or above, given the difficulty of the shot.

Team‑wide eFG% tends to be slightly lower. In the 2021‑22 NBA season, the top five teams by eFG% were:

Rank	Team	eFG%
1	Utah Jazz	56.4 %
2	Golden State Warriors	55.4 %
3	Charlotte Hornets	54.2 %
4	Chicago Bulls	54.1 %
5	Phoenix Suns	53.9 %

These figures show how the metric ranks shooting efficiency across the league.

Why Use an eFG Calculator?

Manually computing eFG% is straightforward, but a dedicated tool eliminates errors and speeds up analysis — whether you’re reviewing a single game or an entire season. As a Basketball Shooting Efficiency Calculator, it gives you a single, weighted number that better reflects true scoring ability than raw field goal percentage.
