NBA Plus Minus Calculator

Plus-minus per 36 minutes from a player's season or game plus/minus and playing time.

What is plus/minus?

Plus/minus records the point swing while a player is on the floor: if his team outscores opponents by 9 during his minutes, he is +9. Raw totals depend heavily on minutes, teammates and matchups, so normalizing per 36 minutes makes players comparable.

How the calculator works

Enter a total plus/minus (season or game), the minutes behind it and optionally games played. The tool returns per-36 and per-game rates.

Common use cases

  • Contextualizing bench units' impact
  • Spotting lineup quirks behind a star's on/off numbers
  • Debating award candidates with a pace-neutral number

Formula & caveats

Plus/minus is noisy in small samples — single-game values are close to meaningless, and a player's number inherits his teammates'. Multi-season on/off and adjusted variants (RAPM) are the serious tools.

Frequently Asked Questions

What is a good plus/minus per 36?

+3 or better across a season is a clear positive impact; −3 or worse is a liability.

Why is per-36 fairer than totals?

It removes playing-time bias so a sixth man can be compared to a starter.

Can a bad player have a good plus/minus?

Yes — riding a great lineup inflates it. That is why adjusted plus/minus exists.
