Craps is one of the most popular casino dice games, but its many betting options can make the odds difficult to understand. Different craps bets have very different probabilities, payouts, and house edges. A bet that looks attractive because it offers a large potential payout may have a much lower chance of winning than a simpler wager.

Our Craps Odds Calculator is designed to make these differences easier to understand. Select a craps bet, enter your wager amount, and the calculator provides the corresponding winning combinations, losing combinations, win probability, lose probability, house edge, potential profit, and potential return.

The tool covers several common craps wagers, including Pass Line, Don't Pass, Come, Don't Come, Field, Any Craps, Hardways, Yo, Any 7, Boxcars, and Snake Eyes. This makes it useful for players who want to compare different bets before deciding how to approach a craps game.

Understanding the numbers behind craps does not guarantee a winning result. Casino games involve risk, and the house edge means that, over the long run, the mathematical expectation favors the casino. Use probability information as a way to understand the game rather than as a promise of profit.

What Is a Craps Odds Calculator?

A craps odds calculator is a tool that estimates the mathematical characteristics of selected craps bets. It uses probability information associated with different wagers to show how frequently a particular outcome can occur based on the dice combinations represented by the bet.

The calculator lets you select from 14 betting options:

• Pass Line
• Don't Pass
• Come
• Don't Come
• Field
• Any Craps
• Hard 6
• Hard 8
• Hard 4
• Hard 10
• Yo (11)
• Any 7
• Boxcars (12)
• Snake Eyes (2)

After you enter your bet amount, the tool calculates several important figures. These include the number of winning and losing combinations used by the calculator, the probability of winning, probability of losing, house edge, potential profit, and potential return.

This information can help you compare bets according to both risk and potential payout.

How to Use the Craps Odds Calculator

Using the calculator is straightforward.

Step 1: Select a Craps Bet

Start by choosing the wager you want to examine from the dropdown menu.

For example, you can select Pass Line if you want to examine one of the standard craps bets, or choose Any 7 if you want to examine a single-roll proposition bet.

Step 2: Enter Your Bet Amount

Enter the amount you are considering wagering.

For example, if you plan to wager $25, enter:

$25

The calculator requires a positive bet amount before it can produce the results.

Step 3: Click Calculate

Select the Calculate button.

The calculator will display the selected bet and its associated figures.

Step 4: Review the Results

The result section provides:

Result	What It Means

Understanding Craps Dice Combinations

Craps uses two standard six-sided dice. When two dice are rolled, there are 36 equally likely combinations.

The possible totals range from 2 through 12.

Some totals have more combinations than others.

Dice Total	Number of Combinations	Probability
2	1	2.778%
3	2	5.556%
4	3	8.333%
5	4	11.111%
6	5	13.889%
7	6	16.667%
8	5	13.889%
9	4	11.111%
10	3	8.333%
11	2	5.556%
12	1	2.778%
Total	36	100%

This distribution is one of the most important concepts in craps.

For example, a 7 can be rolled in six ways:

• 1 + 6
• 2 + 5
• 3 + 4
• 4 + 3
• 5 + 2
• 6 + 1

By comparison, a 2 can occur only as 1 + 1.

That is why Any 7 and Snake Eyes have dramatically different probabilities.

---

Craps Odds Formula Explained

At its simplest, the probability of an outcome can be calculated using:

[
Probability = \frac{Number\ of\ Favorable\ Outcomes}{Total\ Number\ of\ Possible\ Outcomes}
]

With two six-sided dice, there are 36 possible combinations.

For a single-roll wager on 7, there are six winning combinations:

[
Probability = \frac{6}{36}
]

[
Probability = 16.667%
]

This explains why the calculator reports a 16.667% win probability for Any 7.

For Snake Eyes, there is only one winning combination:

[
Probability = \frac{1}{36}
]

[
Probability = 2.778%
]

The same basic probability applies to Boxcars, which is the name commonly used for rolling a 12.

---

Understanding Winning and Losing Combinations

The calculator displays winning and losing combinations for each selected bet.

For example, Any 7 has:

• 6 winning combinations
• 30 losing combinations

There are 36 possible two-dice combinations in total.

Therefore:

[
6 + 30 = 36
]

The win probability is:

[
6 \div 36 \times 100 = 16.667%
]

The lose probability is:

[
30 \div 36 \times 100 = 83.333%
]

This illustrates an important principle: a bet can offer a relatively attractive payout while still having a low probability of winning.

---

What Is the House Edge?

The house edge is the mathematical advantage that the casino has over a player on a particular wager over a large number of plays.

It is generally expressed as a percentage.

For example, if a wager has a 5% house edge, the mathematical expectation is that the casino retains approximately $5 for every $100 wagered over a sufficiently large sample, assuming the stated rules and payout structure remain unchanged.

The house edge should not be interpreted as saying that you will automatically lose exactly that percentage during a short session. Individual results can vary considerably.

A player may win several consecutive bets, lose several bets, or experience a mixture of results. The house edge describes the long-term mathematical expectation, not the result of one roll or one session.

Craps Bets Included in the Calculator

Pass Line

The Pass Line is one of the fundamental craps bets.

According to the calculator's data, it uses:

• 244 winning combinations
• 251 losing combinations
• 49.293% win probability
• 50.707% lose probability
• 1.414% house edge
• 1:1 payout

Pass Line bets are popular partly because they have a relatively low house edge compared with many proposition bets.

Don't Pass

The Don't Pass wager takes the opposite general position from the Pass Line.

The calculator reports:

• 251 winning combinations
• 244 losing combinations
• 47.929% win probability
• 52.071% lose probability
• 1.364% house edge
• 1:1 payout

The probability figures are influenced by the special treatment of certain outcomes in the craps rules.

Come

A Come bet is similar in many ways to a Pass Line bet but is placed after the point phase has begun.

The calculator reports the same basic figures as the Pass Line option:

• 244 winning combinations
• 251 losing combinations
• 49.293% win probability
• 1.414% house edge
• 1:1 payout

Don't Come

Don't Come is the corresponding opposite-style wager to Come.

The calculator lists:

• 251 winning combinations
• 244 losing combinations
• 47.929% win probability
• 1.364% house edge
• 1:1 payout

---

Proposition Bets and Their Probabilities

Some craps bets are often called proposition bets. They can offer much larger payouts, but their probabilities are generally much lower.

Any Craps

Any Craps wins when the roll is 2, 3, or 12.

The calculator reports:

• 4 winning combinations
• 32 losing combinations
• 11.111% win probability
• 11.111% house edge
• 7:1 payout

Hard 6 and Hard 8

A hardway occurs when the total is made using matching dice.

A Hard 6 is specifically:

3 + 3

A Hard 8 is:

4 + 4

Each has one winning combination out of 36.

The calculator reports a 2.778% win probability for each and a 9:1 payout.

Hard 4 and Hard 10

Hard 4 occurs as:

2 + 2

Hard 10 occurs as:

5 + 5

Again, each has one winning combination out of 36.

The calculator lists a 2.778% win probability and a 7:1 payout for these wagers.

Yo (11)

A Yo bet is a wager on rolling 11.

There are two combinations:

• 5 + 6
• 6 + 5

Therefore:

[
2 \div 36 \times 100 = 5.556%
]

The calculator reports a 15:1 payout.

Any 7

Seven has six possible combinations, making it the most common total when two dice are rolled.

The calculator reports:

• 6 winning combinations
• 30 losing combinations
• 16.667% win probability
• 16.667% house edge
• 4:1 payout

Boxcars

Boxcars is another name for a roll of 12.

There is only one way to roll it:

6 + 6

The calculator reports:

• 1 winning combination
• 35 losing combinations
• 2.778% win probability
• 30:1 payout

Snake Eyes

Snake Eyes refers to rolling two ones:

1 + 1

Like Boxcars, there is one winning combination out of 36.

The calculator reports a 2.778% probability and a 30:1 payout.

---

Example 1: Calculating a $25 Pass Line Bet

Suppose you want to examine a $25 Pass Line bet.

Enter:

• Bet: Pass Line
• Amount: $25

The calculator reports a 1:1 payout.

Potential profit:

[
$25 \times 1 = $25
]

Potential return:

[
$25 + $25 = $50
]

The potential profit is therefore $25, while the potential return is $50, which includes your original $25 stake.

The calculator also displays the associated probability and house edge for the Pass Line wager.

---

Example 2: Calculating a $10 Any 7 Bet

Now consider a $10 Any 7 wager.

Enter:

• Bet: Any 7
• Amount: $10

The calculator lists a 4:1 payout.

Potential profit:

[
$10 \times 4 = $40
]

Potential return:

[
$10 + $40 = $50
]

The calculator therefore shows a potential profit of $40 and a potential return of $50.

However, the probability of winning is only 16.667%, while the probability of losing is 83.333%. This demonstrates why payout size alone should not be used to judge whether a wager is favorable.

---

Example 3: Comparing Snake Eyes and Any 7

Suppose you are comparing two $10 bets.

Snake Eyes

The calculator reports:

• Win probability: 2.778%
• Payout: 30:1
• Potential profit: $300
• Potential return: $310

Any 7

The calculator reports:

• Win probability: 16.667%
• Payout: 4:1
• Potential profit: $40
• Potential return: $50

Snake Eyes offers a much larger potential profit, but its probability of winning is substantially lower.

This is an important lesson when comparing craps wagers: potential payout and probability are two different measurements.

---

Probability vs. Payout: Why Both Matter

A common mistake among inexperienced players is to focus exclusively on the payout.

A 30:1 payout may appear much more attractive than a 1:1 payout. However, a wager paying 30:1 can have a very low chance of winning.

Conversely, a lower-paying wager can have a much higher probability of winning.

For example:

Bet	Win Probability	Listed Payout
Pass Line	49.293%	1:1
Any 7	16.667%	4:1
Yo	5.556%	15:1
Snake Eyes	2.778%	30:1
Boxcars	2.778%	30:1

This comparison shows why understanding both probability and payout is essential.

---

Potential Profit vs. Potential Return

These two calculator results are different.

Potential Profit represents the amount won in addition to the original stake.

Potential Return includes both the original wager and the profit.

For example, with a $20 bet and a 4:1 payout:

[
Profit = $20 \times 4 = $80
]

Then:

[
Return = $20 + $80 = $100
]

So the player receives a total of $100 if the wager wins under that payout.

The original $20 is part of the return but is not considered profit.

---

Understanding the House Edge Comparison

The calculator's listed house-edge figures vary significantly among the available bets.

Bet	House Edge Shown
Pass Line	1.414%
Don't Pass	1.364%
Come	1.414%
Don't Come	1.364%
Field	5.556%
Any Craps	11.111%
Hard 6	9.091%
Hard 8	9.091%
Hard 4	11.111%
Hard 10	11.111%
Yo	11.111%
Any 7	16.667%
Boxcars	13.889%
Snake Eyes	13.889%

These figures illustrate why different bets should not be treated as equally favorable from a mathematical perspective.

The relatively low house-edge figures associated with Pass Line, Don't Pass, Come, and Don't Come stand in sharp contrast to many proposition bets.

Tips for Understanding Craps Odds

Learn the Difference Between Bet Types

Craps has many wagers with different rules. Understanding the bet before placing it is more important than simply looking at its payout.

Look at the House Edge

When comparing wagers, the house edge provides useful information about the long-term mathematical disadvantage associated with a bet.

Don't Confuse Probability With Certainty

A 49% probability does not mean you will win approximately half of your next few bets. Probability becomes more meaningful over a large number of trials.

Don't Chase Losses

A losing result does not mean that the next roll is "due" to win. Each dice outcome follows the rules of the game, and previous losses do not create a guaranteed future result.

Set a Budget

Decide how much you are comfortable losing before playing. Never treat gambling as a guaranteed income source or use essential living expenses as a gambling bankroll.

Treat Large Payouts Carefully

High payouts can be appealing, but they often come with substantially lower winning probabilities and higher house edges.

---

Responsible Gambling Reminder

The Craps Odds Calculator is an educational and planning tool. It can help explain probabilities, payouts, and house edge, but it cannot predict the next dice roll or guarantee a profitable outcome.

Casino games are based on chance. Even a bet with a relatively favorable mathematical profile can lose repeatedly in the short term. Likewise, a high-risk wager can occasionally produce a large win.

If you choose to gamble, consider setting strict financial and time limits before you begin. Avoid chasing losses, never gamble money needed for essential expenses, and remember that a calculator cannot change the underlying probabilities of the game.

4. What is the probability of rolling a 7?

There are six combinations that produce a total of 7 out of 36 possible combinations. Therefore, the probability is:

[
6 \div 36 \times 100 = 16.667%
]

5. What does Snake Eyes mean in craps?

Snake Eyes means rolling two ones, producing a total of 2. There is only one combination that produces this result: 1 + 1. The calculator reports a 2.778% probability for Snake Eyes.

6. What are Boxcars in craps?

Boxcars is the common craps term for rolling a total of 12, which occurs when both dice show six. It has one combination out of 36 and therefore a 2.778% probability.

7. Does a higher payout mean a better craps bet?

No. A higher payout does not automatically mean a better mathematical wager. Higher-paying bets often have lower winning probabilities and higher house edges. Both probability and house edge should be considered.

8. What is the difference between potential profit and potential return?

Potential profit is the amount won above the original wager. Potential return is the original wager plus that profit. For example, a $10 bet with a $40 profit has a $50 total return.

9. Can this calculator predict the next craps roll?

No. The calculator provides mathematical probabilities and payout information. It cannot predict which number will appear on the next roll.

10. Does the calculator guarantee that I will make money?

No. There is no guarantee of profit. Gambling outcomes are uncertain, and the house edge represents a mathematical advantage for the casino over the long term. Use the calculator to understand the numbers rather than as a prediction or guarantee.

Conclusion

The Craps Odds Calculator provides a convenient way to compare common craps wagers by showing their winning combinations, losing combinations, probabilities, house edges, and potential payouts. Instead of looking only at how much a bet can pay, you can consider how frequently the underlying outcome occurs and what mathematical disadvantage is associated with the wager.

Understanding the relationship between dice combinations, probability, payout, and house edge is essential for making sense of craps. Pass Line and Don't Pass bets, for example, have very different characteristics from proposition wagers such as Snake Eyes, Boxcars, Any 7, and the Hardways.

Most importantly, remember that probability describes mathematical possibilities rather than guaranteed short-term results. Use this calculator as an educational resource to understand craps odds, keep gambling within a predetermined budget, and never rely on casino games as a source of guaranteed income.
