What is a House Edge in Casino Games? Plain English Guide

What is House Edge?

The house edge is the casino's built-in mathematical advantage on every game. It is the percentage of every wager the casino expects to keep over the long term.

Example: A slot machine with a 4% house edge means for every $100 wagered, the casino expects to keep $4 and return $96 to players.

House Edge Formula

House Edge = 100% - RTP

Common House Edges by Game

*Effective house edge after 50% rakeback. Negative = mathematically favorable.

How House Edge Accumulates

The house edge seems small per bet, but it accumulates:

$100/month wagerer at 4% house edge:

$1,000/month wagerer at 4% house edge:

This is why rakeback matters — it directly reduces this accumulated cost.
