Craps odds calculator

Pick any bet on the layout and any amount. This works out exactly what it pays, how often it wins, what the house keeps, and what it costs you in real money — using the same payout and rounding rules a live table uses.

Every bet, ranked, at this amount

Same wager on every spot, sorted from cheapest to most expensive. This is the whole game in one table: the top rows are where the money should go, and the bottom rows are where the table wants it to go.

Average cost is the amount you lose per bet on average, over the long run. It is not what happens on any one roll — any single bet either wins or loses. The horn and C & E split into equal parts, so they are ranked here at the nearest amount that divides evenly — betting an amount that doesn't split strands part of your chip and makes them far more expensive than the row shows.

How these numbers are worked out

Nothing here is looked up from a chart. Every figure is calculated from the 36 ways two dice can land, the payout the bet actually returns, and the rounding a real table applies.

Take place the 6. The 6 rolls five ways, the 7 rolls six ways, and nothing else matters to this bet, so it wins five times for every six it loses — a 45.5% win chance. It pays 7 to 6. Bet $6 and you collect $7; bet $10 and you collect $11, because the payout floors to the whole dollar exactly like a live table. Over 11 resolutions of a $6 bet you win $35 and lose $36, so the house keeps $1 of every $66 wagered: 1.52%.

The same arithmetic runs on every bet in the list. The 36 combinations explains the underlying probability, and the house edge on every bet walks through the ranked table in prose.

Three things this calculator makes obvious

Free odds are the only bet with no house edge. Set the bet to pass line odds and the edge reads 0.00%, because odds pay true odds — the casino takes nothing. That is why every serious craps strategy is built around betting small on the line and large behind it.

Buy bets change with the amount. Move a buy bet between $5, $20 and $30 and watch the edge swing. The commission is 5% of your bet with a $1 minimum, taken only when you win, so a $5 buy pays that same $1 — a 20% commission — while a $30 buy pays $1 on six times the money. Small buys are a trap; the buy and lay guide has the full breakdown.

The center of the table is where bankrolls go to die. Any seven costs 16.67% per bet, more than ten times the pass line. It is a fine dollar to throw once for the fun of it and a catastrophic way to bet all night. Every prop, ranked covers why they are priced the way they are.
