Season Win Percentage Calculator

Calculate your team's season win percentage based on wins, losses, and optional ties (ties count as half a win).

Your win percentage will appear here.

Formula

Win Percentage = (Wins + 0.5 × Ties) / (Wins + Losses + Ties) × 100

Ties are counted as half a win and half a loss, which is the standard convention used by most professional sports leagues (NFL, NHL, MLS, etc.). If your league does not use ties, simply leave the Ties field blank or enter 0.

Assumptions & References

  • Overtime losses (OTL) used in some leagues (e.g., NHL) are not included here; add them to Losses if applicable.
  • Reference: The Sporting News Official Rules of Baseball; NFL Operations standings methodology; NHL Official Rules, Rule 84.
