PIE
Player Impact Estimate. An all-in-one efficiency number that measures a player's share of everything positive that happened in the games he played.
What PIE measures
Basketball produces many stats that each measure one thing well. PIE folds them into a single number by asking: of every positive action across the games this player appeared in, what share came from him? It is an all-in-one answer to the efficiency question, close in spirit to the EuroLeague's own PIR.
How PIE is calculated
PIE = (PTS + FGM + FTM − FGA − FTA + DREB + 0.5 × OREB + AST + STL + 0.5 × BLK − PF − TO) ÷ the same total for every player in those games
The denominator is the sum of everyone's positive actions across the games the player appeared in, so PIE is a share of activity, not an absolute score.
PIE: Player Impact Estimate / PTS: Points / REB: Rebounds / AST: Assists / STL: Steals / BLK: Blocks / TOV: Turnovers / PF: Personal Fouls
The catch
PIE rewards volume as much as quality
A player who does many things adequately in 30 minutes can out-score a specialist who does one thing brilliantly in 18. PIE adds positive actions up without weighing when they happened. A rebound in garbage time counts the same as a stop with the game on the line.
It is a EuroLeague-shaped number, so keep the comparison local
PIE and PIR are built for EuroLeague data. PER, Win Shares and BPM use different formulas and baselines. A PIE figure tells you nothing directly about what a player's NBA numbers would be. Compare within the league.
Team quality bends individual PIE
A star on a weak team can post a lower PIE than a good player on a great one, simply because the great team wins more and produces bigger game totals to take a share of. PIE is a share of the whole, and the whole is larger in blowouts.
Seen in a game
Vezenkov's 2025–26 season shows why a number like PIE rewards doing many things well over dominating one column. He led the league in PIR at 22.0, not on volume scoring alone but by pairing 18.8 points with 6.2 rebounds and real efficiency, on a team that also passed the ball best in the league. Nadir Hifi of Paris scored nearly as much, 18.9 a game, but posted a PIR of 17.6. The gap is the point: these metrics dock inefficiency and reward the player who contributes across the board.
Common questions
- What is PIE in basketball?
PIE stands for Player Impact Estimate. It is an all-in-one efficiency number that measures a player's share of everything positive that happened in the games he played — scoring, rebounding, assists, steals and blocks, minus the misses and turnovers.
- How is PIE calculated?
PIE adds up a player's positive box-score actions (points, made shots and free throws, rebounds, assists, steals, blocks) and subtracts the negatives (missed shots, turnovers, fouls), then divides by the same total for every player in those games. The result is that player's percentage share of all positive activity.
- What is a good PIE?
A typical starter sits around 10 percent. Above 12 percent is good, and above 15 percent is genuinely elite — the range of players like Sasha Vezenkov, Vasilije Micic and Nikola Mirotic in their best EuroLeague seasons.
- Is PIE the same as PIR?
No. PIE is an NBA-style share-of-activity metric. PIR (Performance Index Rating) is the EuroLeague's own official index, a plus-minus of a player's positive and negative box-score actions in a single number. They measure a similar idea in different ways, so compare each only within its own league.
