How roulette payouts work

Roulette payouts are not estimated — they are fixed ratios set by the rules of the game and identical at every legitimate casino. When a bet wins, the profit is simply your stake multiplied by the payout ratio, and the dealer also returns your original chips. So the two formulas that drive this calculator are:

  • Profit (winnings) = stake × payout ratio
  • Total return = stake × (payout ratio + 1) — your winnings plus the stake you get back

For example, a $10 straight-up bet pays 35:1, so the profit is 10 × 35 = $350 and the total handed back is 10 × 36 = $360. A $10 even-money bet on red pays 1:1, so profit is $10 and total return is $20.

The standard payout table

Every "inside" and "outside" bet covers a fixed number of the wheel's numbers, and its payout is set so that it would be a fair (break-even) bet if the wheel had no zero. Those zero pockets are exactly where the house makes its money.

  • Straight-up (1 number): 35:1
  • Split (2 numbers): 17:1
  • Street (3 numbers): 11:1
  • Corner / Square (4 numbers): 8:1
  • Five-number / basket (0-00-1-2-3, American only): 6:1
  • Six line (6 numbers): 5:1
  • Column or Dozen (12 numbers): 2:1
  • Even-money — Red/Black, Odd/Even, High (19–36)/Low (1–18) (18 numbers): 1:1

Win probability and the house edge

The payout ratio is the same on both wheels, but your chance of winning is not. A European (single-zero) wheel has 37 pockets; an American (double-zero) wheel has 38. The probability a bet wins is simply the count of numbers it covers divided by the total pockets. A straight-up bet wins 1 time in 37 on the European wheel (2.70%) and 1 time in 38 on the American wheel (2.63%).

Because winning bets are paid at the "no-zero" fair ratio while the zeros still exist, the casino keeps a long-run edge. The expected value per $1 staked is −1/37 = −2.70% on a European wheel and −2/38 = −5.26% on an American wheel, and this house edge is the same for nearly every bet type. The lone exception is the American five-number bet, whose edge is 7.89% — the worst wager on the table.

Frequently Asked Questions

How much does a straight-up bet pay?
A single-number (straight-up) bet pays 35 to 1. A winning $10 straight-up bet earns $350 in winnings, and you also get your $10 stake back, for $360 total. The ratio is identical on European and American wheels — only the odds of hitting differ (1 in 37 versus 1 in 38).
Why is the European wheel better than the American wheel?
Both wheels pay the same ratios, but the American wheel adds a second zero (00), making 38 pockets instead of 37. That extra pocket doubles the house edge from 2.70% to 5.26% on almost every bet. If you have the choice, always play a single-zero (European) wheel.
Is there a bet with no house edge?
No. Every standard roulette bet carries the same house edge on a given wheel (2.70% European, 5.26% American), because winning payouts ignore the zero pockets. Some European tables soften this on even-money bets with "La Partage" or "En Prison" rules, which halve the edge to about 1.35%, but this calculator uses the standard full-edge figures.
Does the total return include my original bet?
Yes. "Profit if you win" is just your winnings (stake × ratio). "Total return" adds your stake back on top, because the dealer leaves your original chips on the table when you win. A $20 even-money win returns $40 total: $20 profit plus your $20 stake.
