Craps expected loss per hour depends on total money wagered, the house edge of each bet, and how fast the table moves. A $15 pass line player loses much less in expectation than a player making $15 line bets plus repeated field, hardway, and proposition bets every few rolls.
Quick Facts
- Expected loss is not based only on table minimum.
- Total action means all money wagered, not just the first bet.
- Low house edge can still produce real losses when action is high.
- One-roll bets can increase hourly cost quickly.
- Odds bets have 0% house edge but add volatility.
- Table speed changes the number of decisions per hour.
- Use rounded estimates, not false precision.
Plain Talk
Players often ask, “How much does craps cost per hour?” The honest answer is: count every bet, multiply it by its house edge, and factor in how often those bets are made.
A player betting $15 pass line only has a small expected loss per resolved pass-line cycle. A player betting $15 pass line, $30 odds, $18 each on 6 and 8, plus $5 hardways and field bets has a very different cost profile.
The Wizard of Odds craps basics explains house edge as expected loss compared with the initial wager, and the Wizard craps house-edge appendix discusses the difficulty of measuring edge in craps because many bets stay up across multiple rolls. That distinction is exactly why hourly cost must include total action.
How It Works
You estimate expected loss per hour in four steps:
- List each type of bet you make.
- Estimate how much you wager per hour on that bet.
- Multiply that action by the house edge.
- Add the expected losses together.
| Bet type | Example hourly action | House edge | Expected hourly loss |
|---|---|---|---|
| Pass line | $450 | 1.41% | $6.35 |
| Odds bet | $900 | 0.00% | $0.00 |
| Place 6/8 | $720 | 1.52% | $10.94 |
| Field, triple 12 | $300 | 2.78% | $8.34 |
| Hardways | $150 | ~9% to 11% | about $14 to $17 |
This is why “I only play low-edge craps” can be misleading. If the player adds enough extra bets, the hourly expected loss rises even when the main bet is sensible.
Craps Table Example
Player A plays simply:
- $15 pass line.
- $30 odds after a point.
- No center bets.
- No field.
- No place bets.
Player B plays actively:
- $15 pass line.
- $30 odds.
- $18 place 6.
- $18 place 8.
- $5 field several times per shooter.
- $5 hard 6 and hard 8 when the table feels hot.
Player B may say, “I am still a pass line player.” But the casino records the action, not the self-description. The expected loss comes from every chip that goes to work.
From the Casino Side:
Casinos rate craps players by average bet and time, but the real value of the player is tied to theoretical loss. The floor does not need the player to lose every session. The operation needs enough rated action over enough time.
A boxman or floor supervisor sees more than the pass line. They see odds, place bets, center action, buys, lays, late bets, and pressing behavior. A player who starts with a $15 line bet can become a much higher theoretical-value customer by spreading chips across the layout.
Surveillance cares less about expected loss and more about game protection, but high-action players create more payout events, more chip movement, and more chances for error.
Common Mistakes
- Estimating cost from the table minimum only.
- Ignoring one-roll bets because they are “only $5.”
- Counting odds bets as expected loss even though they are paid at true odds.
- Forgetting that odds bets still increase bankroll swings.
- Using exact-looking hourly estimates from rough assumptions.
- Ignoring table speed.
- Thinking comps are free money instead of a rebate on expected loss.
Hard Truth
The table minimum is not your cost. Your cost is every chip you put into action multiplied by the edge attached to that chip.
FAQ
How do I estimate craps expected loss per hour?
Multiply each bet’s total hourly action by its house edge, then add the results.
Do odds bets increase expected loss?
No. Odds bets have 0% house edge when paid at true odds, but they increase variance and bankroll swings.
Is pass line with odds cheap to play?
It can be lower-cost than many alternatives, but the cost depends on how much total action you add around it.
Why do small prop bets matter?
Because they resolve quickly and often have high house edges. Repeated $5 bets can add up fast.
Can I calculate exact loss per hour?
Only with exact bet frequency and table speed. Most practical estimates use reasonable ranges.
Do comps cover expected loss?
Usually no. Comps are generally a fraction of theoretical loss, not a full refund.
Is a slow table better for the bankroll?
Usually yes, if bet size stays the same. Fewer decisions per hour means fewer opportunities for the edge to work.
Deeper Insight
Expected loss per hour is where craps becomes honest. House edge percentages can sound small. Hourly action turns them into money.
A 1.41% edge sounds tiny. But if a player makes $600 of pass-line action in a long session, the expected loss on that action is about $8.46. Add $1,200 in place-bet action at 1.52%, and that adds another $18.24. Add $300 in hardways at roughly 10%, and that adds about $30.
The biggest leak is not always the main bet. It is often the extra action around the main bet.
Regulated pay schedules, such as those listed in Massachusetts table-game rules, show the formal payout side. The player still has to translate payouts into actual session behavior.
Formula / Calculation
Expected Loss = Total Amount Wagered × House Edge
Expected Loss Per Hour = Hourly Action × House Edge
For multiple bets:
Total Expected Loss Per Hour = Bet A Loss + Bet B Loss + Bet C Loss + …
Example:
- $500 pass-line action × 1.41% = $7.05
- $800 place 6/8 action × 1.52% = $12.16
- $200 field action × 2.78% = $5.56
- $100 hardway action × 10% = $10.00
Total expected hourly loss = $34.77
Formula Explanation in Plain English
Expected loss is the average cost of action. If you put $1,000 through a bet with a 2% house edge, the long-term cost is about $20. You may win today or lose much more today, but the math prices the action at $20.
