How ERA Is Calculated

Formula

ERA = (Earned Runs / Innings Pitched) x 9

ERA normalizes to a 9-inning game so you can compare pitchers with different workloads.

Benchmarks

  • Below 3.00: Excellent (ace-level)
  • 3.00-3.50: Very good
  • 3.50-4.00: Above average
  • 4.00-4.50: Average
  • Above 5.00: Below average

    • Exemple Résolu

    A pitcher allowed 30 earned runs in 100 innings.

    1. ERA = (30 / 100) * 9 = 0.30 * 9 = 2.70
    2. This is an excellent ERA
