Expected Win Rate

In the context of casinos and online gambling venues, the expected win rate is a term used to indicate the percentage of the total money a player is expected to win or lose over a given period of time. This term is most often used in slots and video poker.

For instance, let’s say you play 10 games with a bet of $100 with a 1.030 edge. In this case, the expected win rate would be $30 dollars (calculations: $100 x 10 x 0.30=$30).

Now let’s take a look at a real-world example — a slot machine with a 99.5% payout ratio (0.950 edge). If you were to make 100 spins at $10 a spin, you would win back $950 of the $1,000 you have bet. This puts your expected win rate at -$50 (0.950).
