eFG Calculator
Calculate effective field goal percentage for basketball by giving extra value to three-pointers. eFG% is especially useful when comparing shooters, lineups, or teams that take very different mixes of twos and threes.
eFG Tips
Calculate effective field goal percentage for basketball. Use accurate inputs from the athlete, game, workout, course, or equipment being evaluated. The efg result is most useful when you compare it with a previous performance, a realistic target, or another clearly defined scenario.
Quick Guide
- Enter the exact values requested by the efg tool.
- Use the same measurement units for every related input.
- Compare the result with a real performance or target.
- Recalculate when the player, conditions, or training data changes.
eFG Result
Effective field goal percentage calculated from the exact game, round, workout, or performance inputs entered above.
Compare Scenarios
Change one input at a time to see how volume, efficiency, distance, conditions, or mistakes affect the result.
Use the Stat
Turn the number into a clearer player comparison, team review, practice target, or game-decision note.
Effective Field Goal Percentage Formula and Inputs
eFG% = (FGM + 0.5 × 3PM) ÷ FGA.
The efg is most useful when the inputs all describe the same context. Avoid mixing full-season stats with one-game values unless that is the comparison you intentionally want to make.
| Input | How to Use It |
|---|---|
| Field goals made | Enter the value from the same game, season, round, workout, or scenario you are analyzing. |
| Three-pointers made | Enter the value from the same game, season, round, workout, or scenario you are analyzing. |
| Field goal attempts | Enter the value from the same game, season, round, workout, or scenario you are analyzing. |
Worked eFG Example
If a player makes 8 shots, including 4 threes, on 16 attempts, eFG% is (8 + 0.5 × 4) ÷ 16 = 62.5%.
After calculating the first result, change one input at a time. That makes it easier to see whether volume, efficiency, distance, scoring, mistakes, or conditions are driving the number.
How to Interpret the Result
eFG% adjusts field goal percentage for the added value of three-pointers, making it better for comparing shooters with different shot profiles.
A single stat rarely tells the whole story. Use this calculator as a quick measurement, then compare the result with role, opponent, playing time, course difficulty, weather, pace, sample size, and the level of competition.
Common eFG Mistakes
- Using points instead of field goals made.
- Adding all threes instead of half of made threes.
- Including free throws in eFG%.
- Comparing small samples too strongly.
When to Use the eFG Calculator
Use the eFG Calculator when you need to calculate effective field goal percentage for basketball. It is especially helpful for reviewing a box score, comparing scoring efficiency or overall production, evaluating a player performance, or testing how changes in shots, points, rebounds, assists, turnovers, and minutes affect the result. Enter values such as Field goals made, Three-pointers made, Field goal attempts from the same game, round, workout, event, or time period so the result remains meaningful.
eFG Calculator FAQs
What does this calculator measure?
It calculates effective field goal percentage from the sport-specific inputs entered above.
Can I use this for one game and a full season?
Yes, but keep the time period consistent when comparing results. A one-game result can be noisy, while a season result is usually more stable.
Why does context matter?
Sports stats are affected by role, opponent, playing time, conditions, pace, level of competition, and sample size. The number is useful, but it should not be read in isolation.
Should I round the answer?
For display, rounding is fine. For comparisons or follow-up calculations, keep extra decimal places until the final step.
Can this predict future performance?
It can help describe past performance or compare scenarios, but it should not be treated as a guaranteed prediction.
What should I compare this result against?
Compare it with similar players, teams, rounds, workouts, attempts, distances, or game situations rather than unrelated contexts.
