ERA checklist

  • Use earned runs, not total runs, for ERA.
  • Exclude scrimmages or unofficial outings with the Include switch.
  • Change game length for youth, amateur, or 7-inning formats.
  • Use the next outing plan to see how many ER can be allowed while staying under the target.

How baseball ERA is calculated

ERA uses earned runs only. The calculator converts baseball inning notation into outs, totals included outings, and applies earned runs x game length divided by innings pitched.

Usage notes

  • ERA = earned runs x game length / innings pitched.
  • 6.1 means 6 innings plus 1 out, not 6.1 decimal innings.
  • Allowed ER = floor(target ERA x projected IP / game length - current earned runs).

Frequently asked questions

Should I enter unearned runs?expand_more

Enter them only for reference. ERA calculations use earned runs, while total runs are shown separately for context.

Can I use this for 7 inning games?expand_more

Yes. Change ERA game length to 7 or 6 when your league uses a shorter official game length.
