House Edge Calculator is an independent, free educational site. It explains how the house edge works and what it costs you over time.
What we do
We build simple calculators that turn a game’s house edge into plain dollar figures. For instance, you can see the expected loss for a session before you play.
What we do not do
- We do not run or promote any casino or betting service.
- We do not offer betting tips, systems or predictions.
- We do not accept payment to change any result or figure.
Our approach
We use published house edge figures and standard probability maths. Read the methodology page to see exactly how each result is worked out.
Please gamble responsibly. Read our responsible gambling page for guidance.
