Fill in field goals made, attempts, and threes made. Add optional details for deeper insights and export-ready reporting.
Calculator inputs
Fields marked with * are required.Example dataset
| Player | FGM | FGA | 3PM | eFG% | Notes |
|---|---|---|---|---|---|
| Example Guard | 9 | 18 | 3 | 58.33% | Solid game with efficient threes. |
| Example Wing | 7 | 16 | 1 | 46.88% | Lower value due to fewer threes. |
| Example Center | 8 | 12 | 0 | 66.67% | High efficiency near the rim. |
These examples illustrate how three-point makes raise eFG% versus identical FG%.
Formula used
Effective Field Goal Percentage (eFG%) adjusts field goal percentage by giving extra credit for made three-pointers.
- FGM is total field goals made (2s + 3s).
- 3PM is three-pointers made.
- FGA is total field goal attempts.
- Because a three is worth one extra point, it counts as 1.5 makes in this efficiency view.
How to use this calculator
- Enter FGM, FGA, and 3PM.
- Add 3PA if you want your 3P% displayed.
- Optionally enter points and free throws for TS%.
- Press Calculate eFG% to view results above.

Use it to compare shooters with different three-point volume. It is better than FG% for valuing threes without requiring free throws.
Ensure 3PM is not greater than FGM. If you enter 2PM/2PA and 3PA, they should match totals for clean reporting.
Shooting value beyond FG%
Effective field goal percentage (eFG%) upgrades basic field goal percentage by treating every made three as one-and-a-half makes. Because a three is worth one extra point, eFG% converts shot selection into scoring value without needing free-throw inputs. In a typical game, two players can post the same 50% FG%, yet the player with more made threes produces more points per attempt. Tracking eFG% highlights that gap in a single number and helps explain why offenses prioritize spacing.
Interpreting eFG% ranges
Across many professional and collegiate contexts, 45% to 50% is usually below-average efficiency, 50% to 55% is around average, and 55% to 60% is strong for primary scorers. Values above 60% often indicate elite shot quality, hot shooting, or a rim-and-corner profile. Consider sample size; a one-game spike can regress quickly. When reviewing a series, look for stable trends rather than one outlier night.
Volume, role, and shot profile
A spot-up wing may reach a high eFG% on lower-difficulty looks, while a lead creator often trades efficiency for shot creation. Use this calculator with context: three-point attempt rate, two-point location mix, and late-clock attempts. High rim frequency raises eFG%, midrange volume often lowers it, and pull-up threes create volatility. Pair eFG% with points per 36 minutes to separate “efficient but low volume” from “efficient and high impact.”
Team and lineup applications
For team analysis, enter team totals to compare games, quarters, or specific lineups. eFG% is especially useful for evaluating spacing-driven offense because it rewards threes without requiring free-throw data. Combine eFG% with turnover rate and offensive rebounding to estimate overall scoring efficiency per possession. If a lineup improves eFG% while keeping turnovers flat, it is usually generating cleaner looks through pace, movement, or better shot distribution.
Data hygiene for clean reporting
Accurate inputs matter. Keep three-pointers made less than or equal to total field goals made, and ensure attempts are realistic for the minutes played. If you record 2PA and 3PA, their sum should equal total FGA to avoid mismatched splits. Track the same definitions every game, especially for “team totals” versus “player totals.” Consistent logging makes exports reliable for coaches, analysts, and performance reports.
FAQs
1) What does eFG% measure?
It measures shooting efficiency while giving extra credit to made three-pointers. It answers how valuable a player’s field-goal attempts were, based on points from twos and threes, without including free throws.
2) Why is eFG% better than FG% for comparisons?
FG% treats every made shot the same, but a made three is worth more than a made two. eFG% corrects this by weighting made threes, making cross-player and cross-team comparisons more accurate.
3) Can I calculate team eFG% with this tool?
Yes. Enter team totals for FGM, FGA, and 3PM from a box score. The result gives a team-level snapshot of shot value and helps compare games, lineups, or stretches of play.
4) What inputs are required?
Only FGM, FGA, and 3PM are required. Optional fields like 3PA, 2PM/2PA, points, and free throws add context such as 3P%, 2P%, and an optional true shooting estimate.
5) Why do I see an error about mismatched 2PA and 3PA?
If you enter the optional breakdown, the calculator expects 2PA + 3PA to equal total FGA, and 2PM + 3PM to equal total FGM. This prevents split totals from contradicting the headline inputs.
6) How should I use eFG% alongside other metrics?
Use eFG% with turnover rate, offensive rebounds, and free-throw rate to understand overall scoring efficiency. For players, pair it with usage and minutes to separate “efficient on few shots” from “efficient at scale.”
