Whether you are a beginner learning craps rules or an experienced player analyzing betting strategies, this calculator provides valuable insights into the mathematics behind the game.
What Is a Craps Odds Calculator?
A Craps Odds Calculator is a probability-based tool that estimates the possible outcome of craps bets. It uses the mathematical probabilities associated with different craps wagers to calculate the likelihood of winning and the expected financial results.
In craps, not all bets have the same risk level. Some bets provide better odds for players, while others give the casino a larger advantage.
For example:
- Pass Line bets have a relatively low house edge.
- Don't Pass bets slightly favor the player compared with many other wagers.
- Field bets usually have a higher casino advantage.
By using this calculator, players can compare different bets and understand how probability impacts their potential results.
How to Use the Craps Odds Calculator
Using the Craps Odds Calculator is simple. Follow these steps:
Step 1: Enter Your Bet Amount
Enter the amount of money you plan to wager.
For example:
- $10
- $25
- $50
- $100
The calculator uses this amount to estimate your expected return and possible profit or loss.
Step 2: Select Your Craps Bet Type
Choose the type of craps bet you want to analyze.
Available options include:
Pass Line Bet
The Pass Line bet is one of the most popular craps bets. It is made before the come-out roll and wins if the shooter establishes and completes a point successfully.
Typical house edge:
1.41%
Don't Pass Bet
The Don't Pass bet is sometimes called a "wrong bet" because it bets against the shooter.
This wager generally has a slightly lower house edge than the Pass Line bet.
Typical house edge:
1.36%
Come Bet
The Come bet works similarly to a Pass Line bet but is placed after the point has been established.
Typical house edge:
1.41%
Don't Come Bet
The Don't Come bet works like a Don't Pass bet but is placed after the come-out roll.
Typical house edge:
1.36%
Field Bet
A Field bet is a one-roll wager predicting that the next roll will result in certain numbers.
Although simple, it usually has a higher casino advantage.
Typical house edge:
5.56%
Step 3: Enter Number of Rolls
The number of rolls helps estimate the long-term betting scenario.
For example:
- 50 rolls
- 100 rolls
- 500 rolls
A larger number of rolls gives a better idea of long-term probability trends.
Step 4: Click Calculate
After entering your information, the calculator provides:
- Winning percentage
- Losing percentage
- House edge
- Expected return
- Expected profit or loss
These results help you understand the possible outcome of your selected bet.
Understanding Craps Odds Results
The calculator provides several important measurements.
Winning Probability
Winning probability shows the estimated chance that your selected bet will win.
For example:
If a bet has a winning probability of 49.29%, it means that approximately 49 out of every 100 similar bets may result in a win.
However, probability does not guarantee individual results because dice outcomes are random.
Losing Probability
Losing probability represents the estimated chance of losing the selected wager.
The formula is:
Losing Probability = 100% - Winning Probability
Example:
If winning probability is 49.29%:
100% - 49.29%
= 50.71%
The losing probability is approximately 50.71%.
House Edge
The house edge represents the mathematical advantage the casino has over the player.
For example:
A 1.41% house edge means that over a large number of bets, the casino expects to keep approximately $1.41 for every $100 wagered.
A lower house edge generally means better odds for players.
Expected Return
Expected return estimates the average amount returned from a wager based on probability.
Formula:
Expected Return = Bet Amount × Winning Probability
Example:
If you bet $100 and your winning probability is 49.29%:
Expected Return:
$100 × 0.4929
= $49.29
This does not mean you will receive exactly $49.29 after one bet. It represents the mathematical expectation.
Expected Profit or Loss
Expected profit or loss shows the estimated financial result after considering probability.
Formula:
Expected Profit/Loss = Expected Return - Bet Amount
Example:
Bet amount:
$100
Expected return:
$98.59
Expected result:
$98.59 - $100
= -$1.41
This means the expected long-term loss is approximately $1.41 per $100 wagered.
Craps Odds Calculator Formula Explained
The calculator uses probability formulas based on standard craps mathematics.
Winning Probability Formula
The basic formula is:
Winning Probability (%) = Winning Outcomes ÷ Total Possible Outcomes × 100
Dice have:
6 × 6 = 36 possible combinations
Different combinations create different probabilities for winning or losing.
For example:
- Rolling a 7 or 11 on the come-out roll helps Pass Line bets win.
- Rolling 2, 3, or 12 causes immediate losses.
House Edge Formula
The house edge is calculated using:
House Edge (%) = Casino Expected Advantage ÷ Total Bet Amount × 100
A lower house edge indicates a smaller mathematical disadvantage.
Expected Value Formula
The expected value formula is:
Expected Value = (Probability of Winning × Winning Amount) - (Probability of Losing × Losing Amount)
This helps determine whether a wager is favorable or unfavorable over time.
Practical Example Using the Craps Odds Calculator
Suppose a player enters:
- Bet Amount: $50
- Bet Type: Pass Line Bet
- Number of Rolls: 100
The calculator estimates:
Winning Probability
49.29%
Losing Probability
50.71%
House Edge
1.41%
Expected Return
$24.65
Expected Profit/Loss
Approximately negative due to the casino advantage.
This example shows that even popular bets with low house edges still provide a mathematical advantage to the casino.

Tips for Making Better Craps Decisions
Choose Lower House Edge Bets
Generally, bets with lower house edges provide better long-term chances.
Examples:
- Pass Line bets
- Don't Pass bets
Avoid High House Edge Bets
Some exciting bets may have attractive payouts but come with higher casino advantages.
Always check the mathematical risk before betting.
Set a Budget
Decide your maximum spending limit before playing.
A calculator can show expected outcomes, but it cannot remove randomness.
Understand Probability vs Luck
A player can win a high-risk bet or lose a low-risk bet because each dice roll is independent.
Probability describes long-term patterns, not guaranteed results.
