Divide the number of wins by the total number of games played
Multiply the result by 100 to get a percentage
Formula: Winning Percentage = (Wins ÷ Total Games) × 100
If needed, include ties by using wins plus half of ties in the numerator
Formula with ties: Winning Percentage = ((Wins + 0.5 × Ties) ÷ Total Games) × 100
Example: 8 wins out of 10 games = (8 ÷ 10) × 100 = 80%
