A made three-pointer is worth 50% more than a two, so plain field goal percentage undervalues good three-point shooters. eFG% fixes this: the league average is around 53–55%.
How to use the Effective Field Goal Percentage Calculator
- 2-point field goals made
- 3-point field goals made
- 2-point attempts
- 3-point attempts
Results update as you type, every field has its own unit menu, and everything is calculated in your browser.
How it works
Enter the made and attempted two-point and three-point field goals.
Tips
- Use totals, not per-game averages, for percentages.
- Advanced stats like eFG% and TS% credit three-pointers and free throws properly.
- Compare a player’s numbers with league averages.
- Everything runs in your browser.
Common mistakes to avoid
- Counting free throws as field goals.
- Mixing per-game and season totals.
- Judging shooters from very few attempts.
Inputs explained
| Field | What to enter |
|---|---|
| 2-point field goals made | A number |
| 3-point field goals made | A number |
| 2-point attempts | A number |
| 3-point attempts | A number |
What each result means
- 2-point percentage = [2-point field goals made]÷[2-point attempts]×100
- 3-point percentage = [3-point field goals made]÷[3-point attempts]×100
- Field goal percentage = ([2-point field goals made] + [3-point field goals made])÷([2-point attempts] + [3-point attempts])×100
- Effective field goal percentage = ([2-point field goals made] + 1.5×[3-point field goals made])÷([2-point attempts] + [3-point attempts])×100
- Points from field goals = 2×[2-point field goals made] + 3×[3-point field goals made]
Example values
How the main result changes when 2-point field goals made changes and everything else stays at the example values above:
| 2-point field goals made | Effective field goal percentage (%) |
|---|---|
| 52.5 | 34.92 |
| 78.75 | 43.52 |
| 105 | 52.13 |
| 131.25 | 60.74 |
| 157.5 | 69.34 |
| 210 | 86.56 |
Formula
eFG% = (FGM + 0.5·3PM) ÷ FGA, FGM = 2PM + 3PM, FGA = 2PA + 3PA
Worked example
Inputs — 2-point field goals made: 105; 3-point field goals made: 36; 2-point attempts: 210; 3-point attempts: 95.
Results — 2-point percentage = 50 %; 3-point percentage = 37.89 %; Field goal percentage = 46.23 %; Effective field goal percentage = 52.13 %; Points from field goals = 318.
Key terms
- Field goal
- Any shot other than a free throw.
Frequently asked questions

Above 55% is good for an NBA team; the best shooters exceed 60%.
Why multiply threes by 0.5?
A three is worth 1.5 times a two.

No – use true shooting percentage for that.
How is eFG% related to points per shot?
Points per field goal attempt = 2 × eFG%.
