Pythagorean Wins NHL Calculator

Expected NHL wins from goals scored and allowed using the squared (exponent 2) formula.

What are Pythagorean wins in hockey?

The Bill James concept with hockey's simplest exponent: 2, which makes the formula exactly the Pythagorean theorem shape. Goal differential is a stronger predictor of future points than standings points, especially before Christmas.

How the calculator works

Enter goals for and against; the tool returns expected wins and the implied differential. Expected points ≈ expected wins × 2 for a quick standings translation.

Common use cases

  • Spotting hot-goalie mirages in November
  • Trade deadline buyer/seller reads
  • Goal-differential arguments with receipts

Formula & caveats

Hockey's low scoring makes single-game variance high — expect larger record-vs-differential gaps than in basketball.
