What is a Roulette Payout Calculator?
A roulette payout calculator helps players understand the potential returns on different types of bets in a roulette game. It calculates how much you would win based on your bet amount and the type of bet placed, while also showing the house edge and expected value.
How Roulette Payouts Work
Roulette offers various betting options with different probabilities of winning and corresponding payouts. The payout ratio is typically expressed as "X to 1," meaning you win X units for every 1 unit wagered (plus your original bet is returned).
For example, a straight-up bet on a single number in American roulette has a probability of winning of 1/38 (2.63%). If you win, the casino pays 35 to 1. However, the mathematically fair payout would be 37 to 1. This difference creates the house edge of approximately 5.26%.
Types of Roulette Bets and Their Payouts
- Straight Up (Single Number): Pays 35 to 1
- Split (2 Numbers): Pays 17 to 1
- Street (3 Numbers): Pays 11 to 1
- Corner (4 Numbers): Pays 8 to 1
- Five Number (0, 00, 1, 2, 3): Pays 6 to 1
- Six Line (6 Numbers): Pays 5 to 1
- Dozen (12 Numbers): Pays 2 to 1
- Column (12 Numbers): Pays 2 to 1
- Even/Odd, Red/Black, High/Low (18 Numbers): Pays 1 to 1
House Edge in Roulette
The house edge is the mathematical advantage that the casino has over players in the long run. In American roulette (with 0 and 00), the house edge is 5.26% for most bets. The five-number bet has a higher house edge of 7.89%, making it the least favorable bet.
European roulette has only one zero, reducing the house edge to 2.7%, which is why it's generally preferred by experienced players when available.
Expected Value
The expected value represents the average amount a player can expect to win or lose per bet if they were to place the same bet numerous times. In roulette, all bets (except the five-number bet) have the same expected value of -5.26% in American roulette and -2.7% in European roulette. This means that, on average, for every $100 wagered, a player can expect to lose $5.26 on an American wheel and $2.70 on a European wheel over the long run.

Roulette Strategies
While no betting strategy can overcome the house edge in the long run, some players use systems like the Martingale (doubling bets after losses) or the D'Alembert (increasing bets by one unit after losses). These strategies can affect your short-term results and risk profile but won't change the fundamental mathematics of the game. The most prudent approach is to play roulette for entertainment value, setting a budget and accepting that the house has a mathematical advantage.

Frequently Asked Questions
The main difference is that American roulette has 38 numbers (1-36, 0, and 00), while European roulette has 37 numbers (1-36 and 0). This seemingly small difference significantly affects the odds - American roulette has a house edge of 5.26% for most bets, while European roulette's house edge is only 2.7%. This means European roulette gives players better odds of winning in the long run.
All roulette bets in European roulette have the same house edge of 2.7%, and in American roulette (except for the five-number bet), all bets have a house edge of 5.26%. The five-number bet in American roulette (betting on 0, 00, 1, 2, and 3) has the worst odds with a house edge of 7.89%. While all standard bets have the same house edge, even-money bets like red/black or odd/even have a higher probability of winning (though with smaller payouts), making them less risky for conservative players.
No betting system can overcome the built-in house edge in roulette in the long run. Strategies like the Martingale (doubling bets after losses) or Fibonacci (following a specific sequence of bets) may appear to work in short sessions, but they all eventually fail because: (1) they don't change the underlying odds of each spin, (2) table betting limits prevent indefinite progression, and (3) they often require a large bankroll to implement. Roulette should be played for entertainment, not as a way to make money consistently.
The Five Number bet (also called the "top line" bet) is a wager on the numbers 0, 00, 1, 2, and 3 in American roulette. It's considered the worst bet in roulette because it has the highest house edge at 7.89%, compared to 5.26% for all other bets on an American wheel. This means you lose money faster with this bet than with any other roulette wager. Experienced players typically avoid this bet entirely.
Roulette payouts are calculated based on the odds of winning and the casino's built-in advantage. For example, a straight-up bet on a single number in American roulette has a 1 in 38 chance of winning (2.63%). A fair payout would be 37:1 (reflecting the true odds), but casinos pay 35:1, creating their advantage. The formula for calculating potential winnings is: Payout = Bet Amount × Payout Ratio. So a $10 bet on a single number would pay $350 in winnings (plus your original $10 back) if successful.
The expected return in roulette is negative, reflecting the house edge. For American roulette, the expected return is -5.26% for most bets, meaning for every $100 wagered, a player can expect to lose $5.26 over the long run. For European roulette, the expected return is -2.7%. The expected value is calculated by multiplying each possible outcome's probability by its payout, then summing these values. This negative expected value is why casinos can consistently profit from roulette over time, regardless of short-term results.
