Pick a game and bet, enter your stake and how fast you play, and see the house edge and the expected long-run cost. It covers everything from the best bets in the house to the worst — every craps bet included.
This app's liberal rules push the edge down to ~0.26%.
This is the expected long-run cost, not a guarantee. The math is bet × hands × hours × edge— the average you'd lose over a very large number of hands. Any single session can swing well above or below it. For entertainment only.
The house edge is the share of each bet the casino keeps on average. A 1% edge on a $25 bet costs 25 cents per hand in the long run — small per hand, but it compounds with every wager. That is why pace (hands per hour) and time matter as much as bet size.

Expected cost = bet size × hands (or spins/rolls) per hour × hours played × house edge. It is the average amount you would lose over a very large number of hands — not a prediction of any single session.
Every edge is taken from this site's own odds and simulation figures — for example blackjack about 0.5% (0.26% under our liberal rules), baccarat Banker 1.06%, European roulette 2.70%, and the free Odds bet in craps at 0%.
No. The house edge is a long-run average. Over a single session your results will swing above or below it, sometimes far. The calculator estimates the expected long-run cost, not a guaranteed loss.
