Winning Percentage Calculator
Use this calculator for win rate. With no ties, it is wins over games. With ties counted as half a win, it is (wins + 0.5 × ties) over all games. Excluding ties drops them from the denominator.
How this is calculated
Pick a tie rule first. Half-ties is the usual sports convention. Exclude-ties is wins over decisions only.
half ties: (wins + 0.5 × ties) / (wins + losses + ties) × 100
- 8 wins and 2 losses: 8 / 10 × 100 = 80%.
- 10-6-4 with half ties: (10 + 2) / 20 × 100 = 60%.
- 10-6-4 ignoring ties: 10 / 16 × 100 = 62.5%.
Leave ties at 0 if the sport does not draw. Negative counts are rejected.

Win rate is not a generic part-over-whole unless you already collapsed the record into two numbers.
- X is what percent of Y? Use that if you already have wins and total games as two figures. This tool keeps wins, losses, and ties separate. Open what-percent
