Divide the number of games won by the number of total games played. For instance, if you won seven of the last 10 games: 7/10 = 0.7
Multiply this number by 100 to find the percentage of your win rate. For the example: 0.7 x 100 = 50 percent win rate.
Subtract the number of games won from the total games played to find the number of games lost. For the example: 10 -- 7 = 3 games lost.
Find the loss percentage by dividing the number of games lost by the total played and multiplying the result by 100. For the example: 3/10 = 0.3 x 100 = 30 percent loss rate.
