How Do You Calculate Win in Roulette?

To calculate win in roulette, first find the probability of each type of bet. The probability of a bet is the number of ways to win divided by the total number of possible outcomes. For example, the probability of winning a bet on red is 18/38 because there are 18 ways to win (by hitting red) and 38 possible outcomes (18 red, 18 black, and 2 green). Once you have the probability of each bet, multiply it by the amount you bet to find your expected value for that bet. For example, if you bet $10 on red and the probability of winning is 18/38, then your expected value is $10 * (18/38) = $4.76.

PRO TIP:When playing roulette, it is important to understand the odds of winning and the house edge. The house edge is generally around 5.26%, meaning that for every dollar you wager, you can expect to lose around five cents on average. To calculate your expected winnings, multiply your total stake by the probability of winning (e.g. if you had a $10 bet and the odds of winning were 1 in 37, you would win $10 x (1/37) = approx. 27 cents).

Finally, subtract your expected value from the amount you actually won to find your net winnings. For example, if you won $5 on your bet but your expected value was $4.76, then your net winnings would be $5 – $4.76 = $0.24.
