The EFG (Effective Field Goal Percentage) calculator is used to measure a basketball player’s shooting efficiency by adjusting for the added value of 3-point field goals. Unlike traditional field goal percentage, which treats all field goals equally, effective field goal percentage gives extra weight to 3-pointers because they score more points. This provides a clearer understanding of how effective a player really is when taking shots.
This calculator is especially useful for analysts, coaches, and fans who want to compare players fairly, regardless of whether they attempt more 2-point or 3-point shots. It helps make data-driven decisions for player selection, game strategy, and performance evaluation.
Formula of EFG (Effective Field Goal %) Calculator
eFG% = (FGM + 0.5 * 3PM) / FGA
Where:
FGM = Field Goals Made
3PM = 3-Point Field Goals Made
FGA = Field Goal Attempts
This formula works by giving half an extra weight to 3-point field goals to adjust for their increased value over regular 2-point shots.
Commonly Referenced Values and Quick Conversion Table
Here is a helpful table showing common combinations of shots and how they translate into effective field goal percentages. This makes it easy to understand results without manually calculating each time.
| Field Goals Made (FGM) | 3-Point Made (3PM) | Field Goal Attempts (FGA) | Effective Field Goal % |
|---|---|---|---|
| 4 | 0 | 10 | 0.400 |
| 4 | 2 | 10 | 0.500 |
| 5 | 3 | 10 | 0.650 |
| 6 | 4 | 12 | 0.750 |
| 7 | 5 | 14 | 0.821 |
This table is useful for players, coaches, or anyone evaluating performance. Instead of doing math during or after games, users can quickly look up results and understand efficiency.
Example of EFG (Effective Field Goal %) Calculator
Suppose a player makes 6 field goals out of 15 attempts, including 3 three-point shots. We apply the formula:
eFG% = (6 + 0.5 * 3) / 15
eFG% = 7.5 / 15 = 0.5
So the player’s effective field goal percentage is 50%. Even though they only made 6 out of 15 shots (40%), their eFG% improves because of the extra points gained from 3-pointers.
Most Common FAQs
Field goal percentage (FG%) only considers how many shots are made out of total attempts, treating all shots the same. Effective field goal percentage (eFG%) adjusts for 3-point shots, giving a clearer picture of scoring efficiency.
It helps measure the real value a player brings with their shooting. Since 3-point shots are worth more, eFG% makes sure this extra value is counted. It’s important for judging player performance and for making coaching decisions.
No, effective field goal percentage is a ratio of made shots (with adjustments) to attempts, so it is usually expressed as a number between 0 and 1, or between 0% and 100%.
