Formula Used

This page estimates Player Efficiency Rating using a Hollinger-style unadjusted PER structure, then applies a pace correction. It is a practical calculator for game and season analysis, not an official league service.

Estimated workflow:

uPER = weighted positive actions − weighted negative actions, all divided by minutes played.

Pace adjustment = league pace ÷ team pace.

Adjusted PER = uPER × pace adjustment.

Estimated PER = adjusted PER × (15 ÷ league average uPER baseline).

Positive actions include made shots, assists, rebounds, steals, and blocks. Negative actions include missed shots, missed free throws, turnovers, and personal fouls.

How to Use This Calculator

  2. Fill in team field goals, assists, pace, and rebound context.
  3. Use the default league values or replace them season by season.
  4. Press Calculate PER to show the result above the form.
  5. Review estimated PER, uPER, efficiency percentages, per-36 rates, and Game Score.
  6. Use the chart and export buttons for reporting or sharing.

FAQs

1. What does PER measure?

PER summarizes a player’s box score impact into one pace-adjusted number. It rewards efficient scoring, playmaking, rebounding, steals, and blocks while penalizing missed shots, turnovers, and fouls.

2. Is this the official league PER value?

No. This is an estimated calculator based on a Hollinger-style framework. It is useful for analysis and comparisons, but official published values may differ because of league-wide calibration details.

3. Why does team pace matter?

Players on faster teams naturally produce more counting stats. Pace adjustment helps compare players more fairly by accounting for possessions available during their minutes.

4. Why are league inputs editable?

League environments change over time. Free throw rates, pace, and rebound distribution vary by season, so editable league fields make the estimate more adaptable and realistic.

5. Can I use season totals instead of one game?

Yes. You can enter totals from a season, month, or playoff series. Keep the team and league context aligned with the same sample for cleaner comparisons.

6. What is the difference between uPER and adjusted PER?

uPER is the raw per-minute efficiency estimate. Adjusted PER applies a pace multiplier so players from different team environments can be compared more evenly.

7. Why include Game Score and per-36 stats too?

They add context. PER is broad, while Game Score highlights single-game productivity and per-36 rates show output normalized to playing time.

8. When should I avoid relying on PER alone?

Avoid using PER alone when evaluating defense, spacing, role difficulty, screening, or matchup impact. Combine it with film, lineup data, and possession-based metrics.
