How can a gambler calculate the house edge for a casino?

[Julio88]

Calculating the house edge for a casino is a relatively simple process. The house edge is the mathematical advantage that the casino has over the player in any given game. To calculate the house edge for a casino game, simply subtract the expected return from the player from the expected return for the casino. This will give you the house edge in percentage terms.
For example, if a game has an expected return for the player of 90% and an expected return for the casino of 95%, then the house edge would be 5%. This figure is a representation of the casino’s expected profit from that game.

The gambler can compute it by deducting the expected payment percentage from 100%. The house edge would be 5%, for instance, if the projected payout was 95%. The house edge fluctuates from game to game and even from bet to wager within a single game, which is a crucial fact to keep in mind.
