Roulette Payout Formula Explained
The roulette payout formula is simple:
Payout = Stake × Payout Ratio
For example, if you bet $25 on a split (which pays 17:1), your payout is $25 × 17 = $425. This is your winnings only.
Total Return = Stake + Payout
Your total return includes both your payout and your original stake. In the example above, your total return is $25 + $425 = $450.
Profit = Payout
Your profit is the payout amount, which excludes the returned stake. In this case, your profit is $425.
Payouts for Each Roulette Bet Type
| Bet Type | Payout Ratio | Numbers Covered |
|---|---|---|
| Straight Up | 35:1 | 1 |
| Split | 17:1 | 2 |
| Street | 11:1 | 3 |
| Corner | 8:1 | 4 |
| Six Line | 5:1 | 6 |
| Red / Black | 1:1 | 18 |
| Even / Odd | 1:1 | 18 |
| High / Low | 1:1 | 18 |
| Dozens | 2:1 | 12 |
| Columns | 2:1 | 12 |

European vs American Roulette Calculator Differences
The payout ratios are identical in both European and American roulette. However, the probability of winning and house edge differ.
European roulette has 37 total pockets (numbers 1-36 plus a single zero). The house edge is 2.70% on all bets.
American roulette has 38 total pockets (numbers 1-36 plus both a single zero and a double zero). The house edge is 5.26% on all standard bets.
The extra pocket in American roulette reduces your winning probability on every bet type. For instance, a red/black bet wins 48.65% of the time on a European wheel but only 47.37% on an American wheel.
For a complete breakdown of the differences, see American vs European roulette.
Probability of Winning Each Bet
Probability is calculated as:
Probability = (Numbers Covered ÷ Total Pockets) × 100
In European roulette (37 pockets):
- Straight up: 1/37 = 2.70%
- Red/Black: 18/37 = 48.65%
- Dozens: 12/37 = 32.43%
In American roulette (38 pockets):
- Straight up: 1/38 = 2.63%
- Red/Black: 18/38 = 47.37%
- Dozens: 12/38 = 31.58%
Higher probabilities mean more frequent wins, but lower payout ratios. Lower probabilities mean less frequent wins, but higher payout ratios.
House Edge and Expected Loss
The house edge represents the casino's mathematical advantage, expressed as a percentage of your total wagers over time.
For European roulette, the house edge is 2.70%. This means that for every $100 wagered, you can expect to lose $2.70 on average in the long run.
For American roulette, the house edge is 5.26%. For every $100 wagered, you can expect to lose $5.26 on average.
The house edge applies equally to all standard roulette bets. A straight up bet and a red/black bet both have the same house edge on the same wheel type.

Common Calculation Mistakes Players Make
Confusing profit with total return. Profit is your winnings only. Total return includes your original stake. A $10 bet at 8:1 gives you $80 profit and $90 total return.
Thinking higher payouts mean better bets. Higher payout ratios simply compensate for lower probabilities. All standard roulette bets have the same house edge.
Not accounting for the extra zero in American roulette. While payout ratios stay the same, your win probability drops on every bet due to the extra pocket.
Believing betting systems change payout calculations. No betting pattern or progression system changes the fixed payout ratios or house edge. Each spin is independent.
