Calculator Inputs
Tip: Enter either totals (FGM/FGA) or the 2P/3P split. The calculator can fill in missing totals when possible.

Formula Used
- FG% = (FGM ÷ FGA) × 100
- 2P% = (2PM ÷ 2PA) × 100
- 3P% = (3PM ÷ 3PA) × 100
- eFG% = ((FGM + 0.5×3PM) ÷ FGA) × 100
- 3PA Rate = (3PA ÷ FGA) × 100
- Points/Shot = Points ÷ FGA
- FG% = (FGM ÷ FGA) × 100
- XP% = (XPM ÷ XPA) × 100
- Range FG% = (Made ÷ Attempts) × 100
- Longest is a user-entered benchmark value
How to Use This Calculator

Baseline Field Goal Percentage
Field goal percentage (FG%) is the core efficiency signal: made shots divided by attempts. In many basketball settings, 45% is a solid baseline, 50% is strong, and 55% usually reflects high-quality looks at the rim. Guards often sit near 43–48%, while interior finishers can reach 55–65%. Log FGM and FGA per game, then compare week-to-week changes to confirm whether practice is transferring to games.
Volume and Stability
Percentages can swing when attempts are low. A 4-for-6 night (66.7%) looks elite, but it is only six shots; 9-for-18 (50.0%) is often more representative. Track attempts alongside FG% and watch for stability once a player reaches roughly 80–120 shots in a sample window. Use a rolling 10-game average plus the season number so one outlier does not drive decisions. Per‑36 rates help normalize pace when minutes vary.
Shot Value and eFG%
Two players can share the same FG% but create different scoring value. Effective field goal percentage (eFG%) adds a 0.5 bonus to made threes because they are worth an extra point. Example: 8/16 with four threes gives eFG% = (8 + 0.5×4)/16 = 62.5%, not 50.0%. Pair eFG% with three‑point attempt rate to balance spacing and efficiency, and use points per shot to summarize scoring impact per attempt.
Range Splits for Kicking
For football kicking, overall FG% is meaningful, but distance splits explain reliability. Many teams expect around 85–95% from 0–39 yards, 70–85% from 40–49, and 55–75% from 50+. Enter made and attempted by range to spot where mechanics break down. Extra-point percentage is typically higher, so a drop there can highlight timing or snap/hold issues.
Reporting and Coaching Workflow
Use notes to capture context like fatigue, defensive pressure, wind, or late‑clock attempts. Export CSV for season tracking and PDF for quick sharing with coaches. Review results monthly and raise difficulty only when efficiency stays steady at target volumes, such as keeping eFG% above 52% while increasing three‑point rate by 3–5 points. Convert the same targets into drills, then re-enter the session totals to verify progress. This feedback loop keeps selection, confidence, and effort aligned daily.
FAQs
1. What does field goal percentage measure?
It measures scoring efficiency by dividing made field goals by attempted field goals, then multiplying by 100. Higher values usually indicate better shot selection, touch, or kicking consistency.
2. Why is eFG% included for basketball?
eFG% adjusts for shot value by giving extra credit to made three‑pointers. It helps compare players who take different mixes of twos and threes using a single efficiency number.
3. What happens if attempts are zero?
The calculator shows a dash instead of a percentage when attempts are missing or zero. This prevents misleading results and reminds you to enter valid attempt totals.
4. Do I need to enter 2P and 3P splits?
No. Totals are enough for overall FG%. Splits unlock 2P%, 3P%, eFG%, and three‑point attempt rate, which are useful for coaching shot distribution.
5. How are per‑36 rates calculated?
If minutes are entered, the tool scales makes and attempts to a 36‑minute pace: stat per 36 = (stat ÷ minutes) × 36. It supports fair comparisons across changing playing time.
6. Can I use this for football kickers?
Yes. Select football mode to calculate FG%, extra‑point percentage, and optional distance‑range percentages. Use range splits to identify where accuracy drops as distance increases.
