Basketball Stats Calculator Guide: Key Metrics Explained (2026)
Quick Answer
The most important basketball stats are points, rebounds, assists, steals, and blocks per game — but advanced metrics tell a deeper story. True Shooting Percentage (TS%) measures shooting efficiency accounting for 3-pointers and free throws. PER (Player Efficiency Rating) summarizes overall contribution in a single number, with 15 being average and 25+ being MVP-level.
Basic Basketball Stats Explained
The box score is basketball's foundation. These counting stats appear in every game summary and form the basis for player evaluation at every level from high school to the NBA.
Points Per Game (PPG)
The most watched number in basketball. PPG = Total Points ÷ Games Played.The NBA scoring champion in 2025–26 averaged over 30 PPG. League average for all players is around 8–9 PPG, but starters average closer to 14–15. The all-time single-season scoring record is Wilt Chamberlain's 50.4 PPG in 1961–62, per Basketball Reference.
Rebounds Per Game (RPG)
RPG = Total Rebounds ÷ Games Played.Rebounds split into offensive (OREB) and defensive (DREB). An average starting center grabs 8–10 per game. Guards typically average 3–5. All-time, Wilt Chamberlain holds the career average record at 22.9 RPG.
Assists Per Game (APG)
APG = Total Assists ÷ Games Played.An assist is credited when a pass directly leads to a made basket. Elite playmakers average 10+ APG. John Stockton holds the career APG record at 10.5. Average NBA starter sits around 3–4 APG.
Steals (SPG) and Blocks (BPG)
Defensive box score stats. SPG = Steals ÷ Games Played; BPG = Blocks ÷ Games Played. A steal of 2.0+ per game is elite; anything above 3.0 BPG leads the league most seasons. According to NBA.com/stats, average starters average approximately 0.8 SPG and 0.5 BPG.
Field Goal Percentage (FG%), 3-Point % (3P%), and Free Throw % (FT%)
Each follows the same formula: Makes ÷ Attempts × 100.NBA averages in 2025–26: FG% ~47%, 3P% ~36%, FT% ~77%. The 50–40–90 club (50% FG, 40% 3P, 90% FT in a season) is one of basketball's most exclusive statistical achievements — fewer than 20 times achieved in NBA history.
Turnovers (TO)
Lower is better. TO Per Game = Total Turnovers ÷ Games Played.High-usage stars often turn the ball over 3–4 times per game. Context matters: a player with 4 APG and 2 TOV is doing better than one with 4 APG and 4 TOV.
Advanced Stats: True Shooting % and Effective FG%
Field goal percentage has a fundamental flaw: it treats every make the same. A 2-point layup counts the same as a 3-point corner jumper, even though the 3-pointer generates 50% more points. Advanced shooting metrics fix that.
Effective Field Goal Percentage (eFG%)
eFG% = (FGM + 0.5 × 3PM) ÷ FGA
This adjusts field goal percentage to give 3-pointers extra credit. A player who hits 45% of his shots exclusively on 3-pointers has an eFG% of 67.5% — far better than the raw 45% suggests.
True Shooting Percentage (TS%)
TS% = Points ÷ (2 × (FGA + 0.44 × FTA))
TS% goes further than eFG% by folding in free throws. The 0.44 factor accounts for the fact that not every trip to the line is a standard 2-shot foul — some result from and-ones or technical fouls. According to ESPN Stats & Info, the NBA league average TS% has consistently hovered around 57–58%. A TS% above 60% places a player among the most efficient scorers in the league.
Why TS% beats FG%: a player who scores 20 PPG on 42% FG while drawing fouls at an elite rate might have a TS% of 60%+. Raw FG% makes him look pedestrian. TS% reveals the truth.
| TS% Range | What It Means |
|---|---|
| Below 50% | Below average efficiency |
| 50–55% | Average to slightly below |
| 55–60% | Good — league average zone |
| 60–65% | Excellent, All-Star level |
| 65%+ | Elite, historically efficient |
PER: Player Efficiency Rating Explained
PER was developed by John Hollinger and popularized by ESPN. It condenses everything a player does — scoring, rebounding, assists, steals, blocks, turnovers, missed shots — into a single per-minute efficiency number, then scales it so the league average is exactly 15.
How PER Is Calculated
The full formula is complex (it weights each stat, adjusts for pace, and normalizes league-wide), but the core concept is simple: positive contributions (points, rebounds, assists, steals, blocks) add to PER, and negative contributions (turnovers, missed shots) subtract. Minutes played create the denominator so players can be compared fairly across different roles.
The formula in simplified form: PER = (Positive stats − Negative stats) ÷ Minutes × Pace adjustment × League normalization factor
PER Benchmarks
| PER | Player Tier |
|---|---|
| Below 10 | Below replacement level |
| 10–14.9 | Rotation player |
| 15.0 | League average |
| 15–20 | Solid starter |
| 20–24.9 | All-Star caliber |
| 25+ | MVP-level |
| 30+ | All-time great season |
All-time PER leaders include Michael Jordan (27.9 career), LeBron James (27.1), and Shaquille O'Neal (26.4). In recent seasons, Nikola Jokic has posted PERs above 31 — the highest single-season marks of the modern era, per Basketball Reference.
PER Limitations
PER has real weaknesses. It undervalues perimeter defense (steals are included, but contested shots and positioning are not). It rewards high-volume scorers even when their efficiency is poor, and it can inflate numbers for players on slower-paced teams. Analysts typically use PER as a starting point rather than a final verdict.
Usage Rate and Plus/Minus
Usage Rate (USG%)
USG% = 100 × ((FGA + 0.44 × FTA + TOV) × (Team MP / 5)) ÷ (MP × (Team FGA + 0.44 × Team FTA + Team TOV))
Usage rate estimates the share of team possessions a player uses while on the floor. The league average is around 20%. High-usage stars like Luka Doncic and Giannis Antetokounmpo routinely exceed 35%, according to FanDuel Research's NBA analytics reports. Usage rate matters for context: a player averaging 25 PPG on 25% usage is more impressive than the same output on 35% usage.
Plus/Minus (+/–)
Raw plus/minus is the simplest impact metric: it counts how many more points your team scored than the opponent while you were on the court. A +8 in 20 minutes means your team outscored the opponent by 8 during your time on the floor.
Raw +/– is noisy — it is heavily influenced by teammates. That's why advanced versions exist:
- Box Plus/Minus (BPM): Uses box score stats to estimate a player's contribution per 100 possessions, relative to league average. Available on Basketball Reference.
- Adjusted Plus/Minus (APM) / RAPM: Uses lineup data to isolate individual impact while controlling for teammates and opponents.
- On/Off Splits: Compare team performance per 100 possessions with the player on versus off the court. A player whose team scores 115 points per 100 possessions with him on the floor and 108 with him off has a net rating of +7 — a strong indicator of real impact per Nylon Calculus analysis.
NBA Stat Benchmarks by Player Level
These thresholds represent typical performance tiers in the NBA. Benchmarks are based on data from Basketball Reference and NBA.com/stats for the 2024–25 season.
| Stat | Average Starter | All-Star Level | MVP Level |
|---|---|---|---|
| PPG | 14–16 | 22–28 | 28+ |
| RPG | 4–6 | 8–11 | 11+ |
| APG | 3–5 | 6–9 | 9+ |
| TS% | 54–58% | 58–63% | 63%+ |
| PER | 15–18 | 20–24 | 25+ |
| USG% | 18–22% | 26–30% | 30%+ |
| Net Rating | 0 to +3 | +4 to +8 | +8+ |
Context always matters. A player averaging 16 PPG with a 62% TS% and strong defensive metrics might be more valuable than a 25 PPG scorer with poor efficiency and a negative +/–. That's why analysts use a basket of metrics rather than any single number.

What is a good PER in basketball?
The NBA average PER is 15.0 by design — John Hollinger calibrated the formula that way. A PER above 20 is considered All-Star level, and 25 or higher is MVP territory. The all-time single-season record belongs to Wilt Chamberlain (31.82 in 1962–63). Active players like Nikola Jokic have averaged PERs above 30 in recent seasons.
What is True Shooting Percentage (TS%)?
True Shooting Percentage measures overall shooting efficiency accounting for 2-pointers, 3-pointers, and free throws. The formula is: TS% = Points ÷ (2 × (FGA + 0.44 × FTA)). The NBA league average is around 57–58%. A TS% above 60% is elite.
What does usage rate mean in basketball?
Usage rate (USG%) estimates the percentage of team possessions a player uses while on the floor — through field goal attempts, free throw attempts, or turnovers. The NBA average is around 20%. Stars like Luka Doncic and Giannis regularly exceed 35%, according to FanDuel Research.
What is plus/minus (+/–) in basketball?
Plus/minus measures the point differential when a player is on the court. If your team outscores the opponent by 8 during your 20 minutes of play, your raw +/– is +8. Box Plus/Minus (BPM) and on/off net rating are more reliable versions that control for teammate and opponent quality.
How is field goal percentage different from True Shooting Percentage?
FG% counts made field goals divided by attempts — it ignores free throws and treats 3-pointers the same as 2-pointers. True Shooting Percentage corrects both flaws. A player who makes 45% of his shots but draws lots of fouls and shoots beyond the arc heavily could have a TS% of 60%+ — a much more accurate picture.
What counting stats matter most in basketball?
Points per game (PPG), rebounds per game (RPG), and assists per game (APG) are the most cited basic stats. Steals (SPG) and blocks (BPG) add defensive context. According to Basketball Reference, average NBA starters post roughly 14.5 PPG, 5.0 RPG, and 3.1 APG per game. For a more complete picture, pair these with TS% and +/–.
