Craps RTP means return to player: the long-run percentage of wagered money a bet is expected to return before real-session variance. If a craps bet has a 1.41% house edge, its RTP is about 98.59%. High RTP is better than low RTP, but it does not mean the bet is safe, profitable, or low-risk tonight.
Quick Facts
- RTP stands for return to player.
- RTP and house edge are opposites: 98.59% RTP means 1.41% house edge.
- Pass Line RTP is about 98.59%.
- Don’t Pass RTP is about 98.64% when 12 pushes.
- Odds bets have 100% RTP because they are paid at true odds.
- Proposition bets often have much lower RTP.
- RTP is long-run math, not a session forecast.
Plain Talk
RTP is the cleanest way to say, “How much of the wager is priced to come back to players over the long run?”
A 98.59% RTP does not mean you get back $98.59 from every $100 session. It means that across a very large number of resolved bets, the math prices the average return at roughly $98.59 per $100 wagered.
That missing $1.41 is the house edge.
This page is about RTP as a math label. For the full bet menu, start with the craps guide. For probability by bet type, use craps odds. For casino advantage, read craps house edge.
The Wizard of Odds craps basics lists common craps house edges, while its craps appendix breaks down probability and expected return. For dice probability background, Wolfram MathWorld on dice is useful because craps math begins with the 36 two-dice combinations.
How It Works
RTP is calculated from house edge.
| Bet | Approx. House Edge | Approx. RTP | What It Means |
|---|---|---|---|
| Odds Bet | 0.00% | 100.00% | Paid at true odds |
| Don’t Pass | 1.36% | 98.64% | Slightly better than Pass Line |
| Pass Line | 1.41% | 98.59% | Standard low-edge line bet |
| Come | 1.41% | 98.59% | Same math as Pass Line after a point exists |
| Place 6 or 8 | 1.52% | 98.48% | Good-value Place bet |
| Place 5 or 9 | 4.00% | 96.00% | Noticeably more expensive |
| Any Seven | 16.67% | 83.33% | Very costly one-roll bet |
RTP makes bet comparison easier because it turns house edge into a return number.
But do not let the percentage fool you. A bet with strong RTP can still swing hard. Craps is not a steady drip-return machine. It is dice, pace, bankroll, table minimums, and player behavior.
RTP on Odds Bets
Odds bets are the special case. They pay true odds:
| Point | True Odds Payout | Why |
|---|---|---|
| 4 or 10 | 2 to 1 | Six ways to roll 7, three ways to roll 4 or 10 |
| 5 or 9 | 3 to 2 | Six ways to roll 7, four ways to roll 5 or 9 |
| 6 or 8 | 6 to 5 | Six ways to roll 7, five ways to roll 6 or 8 |
Because the payout matches the risk, the odds portion has 100% RTP.
That does not make the full hand risk-free. It only means the casino is not taking mathematical edge on that added odds portion.
Craps Table Example
You play a $10 Pass Line bet and take $20 odds after the point becomes 6.
The Pass Line portion has about 98.59% RTP. The $20 odds portion has 100% RTP.
If the 6 rolls before 7, the Pass Line wins $10 and the odds pay $24 because odds behind 6 pay 6 to 5. If 7 rolls first, both the $10 line bet and $20 odds bet lose.
The combined wager has a lower blended house edge than a flat $10 Pass Line bet alone, but the total money at risk is now $30. RTP improved. Variance increased.
That is the trade.
From the Casino Side:
Casino managers do not think of RTP as a promise to one player. They think in terms of hold, volume, table speed, average bet, and mix of wagers.
A table full of players making Pass Line with odds may have strong RTP from the player’s view, but the casino still earns through total action, mistakes, side bets, proposition bets, and long operating time. One player might leave ahead. The table may even lose money for a shift. The game survives because the average over time favors the house.
Surveillance does not care that a bet has 98.59% RTP. Surveillance cares whether the bet was booked properly, paid correctly, and protected from late action.
The floor cares about rating. A player betting $10 flat with $50 odds may create more visible action, but the odds portion is often rated differently because it has no house edge.
Common Mistakes
- Thinking RTP predicts what happens during one session.
- Believing 100% RTP on odds means the entire craps hand is break-even.
- Comparing RTP without comparing bet speed.
- Ignoring total action.
- Treating a high-RTP bet as bankroll-safe.
- Forgetting that proposition bets can drain money quickly despite small chip sizes.
- Confusing RTP with “chance of winning.”
Hard Truth
RTP tells you the price of the bet, not the mood of the dice. A 98.59% bet can still take your full buy-in if you bet too much, too fast, for too long.
FAQ
What does RTP mean in craps?
RTP means return to player. It is the long-run percentage of wagered money a bet is expected to return.
How do you calculate craps RTP?
Subtract the house edge from 100%. A 1.41% house edge means about 98.59% RTP.
Which craps bet has the highest RTP?
The odds bet has 100% RTP because it is paid at true odds. Among common edge bets, Don’t Pass is slightly better than Pass Line.
Does 100% RTP mean I cannot lose?
No. It means the payout has no built-in house edge. You can still lose the bet, and odds bets can be large.
Is RTP the same as probability of winning?
No. RTP combines probability and payout. A bet can win often and still have poor RTP if the payout is short.
Why do casinos offer high-RTP bets?
Because high RTP does not remove all casino profit. Players add odds, make side bets, increase action, play longer, and make mistakes.
Should beginners choose only high-RTP bets?
Usually yes as a cost-control rule, but bankroll size and total action still matter.
Deeper Insight
RTP is most useful when comparing bets with different payouts.
Pass Line and Any Seven are both simple to understand. One is a low-edge contract-style bet. The other is a one-roll proposition bet with a heavy casino advantage. RTP exposes that difference without needing to tell a long story.
But RTP has limits.
First, RTP is long-run. It does not smooth out short sessions.
Second, RTP does not show variance. A 100% RTP odds bet behind the 4 can still lose two-thirds of the time once the point is 4, because 7 has six combinations and 4 has three. The payout is fair, but the hit rate is not high.
Third, RTP can be diluted or improved by combining bets. Pass Line plus odds lowers the blended edge because some of the money is placed on a 0% edge odds bet. That is good math. It also puts more dollars at risk per decision.
That is why why low house edge does not mean safe matters. Low price is not the same as low volatility.
Formula / Calculation
RTP = 100% - House Edge
Expected Loss = Total Amount Wagered × House Edge
House Edge = -Player EV / Initial StakeExamples:
Pass Line RTP = 100% - 1.41% = 98.59%
Don't Pass RTP = 100% - 1.36% = 98.64%
Any Seven RTP = 100% - 16.67% = 83.33%For $500 of total resolved action:
$500 × 1.41% ≈ $7.05 expected loss
$500 × 16.67% ≈ $83.35 expected lossFormula Explanation in Plain English
RTP is the amount the bet is priced to return over a huge sample. House edge is the amount the casino is priced to keep. If the house edge goes up, RTP goes down. If you bet more total money, the expected dollar loss rises even if the percentage looks small.
