Turn box score lines into a clear impact rating. See missed shots, turnovers, and rebounds. Save a report and share it with coaches.
Fields accept decimals. Minutes is required. Keep attempts consistent with makes.
Use these sample numbers to test the calculator.

| Sample B | 28.5 | 14 | 5 | 12 | 1 | 3 | 4 | 1 | 5 | 3 | 1 | 0 | 2 | 3 |
| Sample C | 18.0 | 9 | 3 | 7 | 0 | 3 | 4 | 0 | 3 | 2 | 0 | 1 | 1 | 1 |
This calculator uses a simplified PER-style efficiency score based on common box score events. It is designed for quick comparisons across games when you have the same stat set available.
Notes: The official Hollinger PER uses league factors, pace, and detailed weights. This tool intentionally keeps inputs simple for everyday stat sheets.
A single game box score contains many signals. This calculator converts those signals into one PER-style number, scaled to 15 minutes, so different playing times remain comparable. For example, two players can both score 18 points, but the one who adds rebounds, assists, steals, and blocks while limiting misses and turnovers will rate higher. Coaches often use one-number summaries for quick review, then drill into details for film.
The score rewards positive events: points, total rebounds (ORB+DRB), assists, steals, and blocks. It subtracts missed field goals (FGA−FGM), missed free throws (FTA−FTM), turnovers, and personal fouls. Minutes are the denominator, so every extra minute without production reduces efficiency. If you track three-pointers, the tool also reports eFG% and True Shooting %, giving a shooting-quality view alongside the impact score.
The impact labels are practical bands for internal comparison. A value near 15 suggests a balanced game at a solid per-minute rate. Scores above 18 typically indicate a strong all-around contribution, while 22+ represents elite box-score dominance. Lower values often reflect high misses, fouls, or turnovers relative to minutes. Use the band as a starting point, not a final verdict, because roles differ by position and system.
For clean comparisons, keep stat sources consistent and avoid mixing league rules. Compare players within the same competition and season window. Use similar minute ranges when possible, and note that end-game fouling or intentional fast pace can inflate certain box events. When a player has zero turnovers, the AST/TOV helper shows a dash to avoid division distortion; review raw turnovers in that case.
After submitting, the result appears above the form for immediate review. Download CSV to build trend lines across games, or export PDF for staff packets and player feedback sessions. Many teams track three checkpoints: pre-game average, last five games, and last ten games. Saving those snapshots alongside notes about opponent strength and injury context makes the efficiency score far more actionable over time. It supports clear weekly reviews.
No. It is a simplified PER-style efficiency score using common box-score inputs. Official PER uses league pace factors and weighted constants. Use this tool for fast, consistent comparisons when full league parameters are unavailable.
Scaling to 15 minutes normalizes performance across different playing times. It keeps the score readable and makes bench and starter games easier to compare on a per-minute basis.
The calculator requires minutes greater than zero because it divides by minutes. Enter actual minutes played, including decimals, to avoid inflated or undefined outputs.
Turnovers and personal fouls are subtracted because they typically reduce possessions or create opponent advantages. If your league records different foul rules, keep comparisons within the same rule set.
It includes steals and blocks, which capture some defensive impact, but it cannot measure positioning, contests, or scheme discipline. Pair the score with film review and role-based expectations.
Yes. Export CSV after each game, then compute rolling averages such as last five and last ten games. Track context notes like opponent strength and minutes restrictions to interpret changes correctly.
