Payouts and odds
Roulette Payouts and Odds for Every Bet
The payout is your profit on a winning bet; your stake comes back on top. Covering more numbers wins more often but pays less, and on a standard wheel every bet ends up with the same house edge, with one exception.
| Bet | Covers | Pays | Wins on a single-zero wheel | Wins on a double-zero wheel | House edge |
|---|---|---|---|---|---|
| StraightAny single number, including 0 or 00. | 1 number | 35 to 1 | 2.7% (1 in 37) | 2.6% (1 in 38) | 2.70% / 5.26% |
| SplitOn the line between two numbers. | 2 numbers | 17 to 1 | 5.4% (1 in 18.5) | 5.3% (1 in 19) | 2.70% / 5.26% |
| StreetA row of three, such as 13, 14, 15. | 3 numbers | 11 to 1 | 8.1% (1 in 12.3) | 7.9% (1 in 12.7) | 2.70% / 5.26% |
| Trio0, 1, 2 or 0, 2, 3 (00, 2, 3 on a double-zero table). | 3 numbers | 11 to 1 | 8.1% (1 in 12.3) | 7.9% (1 in 12.7) | 2.70% / 5.26% |
| CornerWhere four numbers meet. | 4 numbers | 8 to 1 | 10.8% (1 in 9.3) | 10.5% (1 in 9.5) | 2.70% / 5.26% |
| First four0, 1, 2, 3. Single-zero tables only. | 4 numbers | 8 to 1 | 10.8% (1 in 9.3) | – | 2.70% |
| Five-number0, 00, 1, 2, 3. Double-zero tables only. | 5 numbers | 6 to 1 | – | 13.2% (1 in 7.6) | 7.89% |
| Six lineTwo streets side by side. | 6 numbers | 5 to 1 | 16.2% (1 in 6.2) | 15.8% (1 in 6.3) | 2.70% / 5.26% |
| Dozen or column1 to 12, 13 to 24, 25 to 36, or a column of 12. | 12 numbers | 2 to 1 | 32.4% (1 in 3.1) | 31.6% (1 in 3.2) | 2.70% / 5.26% |
| Red, black, odd, even, 1–18, 19–36Zero loses these, except under La Partage. | 18 numbers | 1 to 1 | 48.6% (1 in 2.1) | 47.4% (1 in 2.1) | 2.70% / 5.26% |
House edge shown as single zero / double zero. On a French table, La Partage returns half of an even-money bet when zero lands, which cuts the edge on those bets to 1.35%. Odds are covered pockets divided by total pockets. Why the second zero nearly doubles the edge: European vs American roulette. All the French rules are in our French roulette guide, and a third zero takes every bet to 7.69%: see triple zero roulette.
Worked examples
What a $2.50 Bet Pays
Same stake, three placements. Where the chip sits decides how many numbers it covers and what it pays.
Straight on 17
- Profit if it wins
- $87.50
- Back in your hand
- $90
Only 17 wins. The $87.50 is profit and the other $2.50 is your stake coming back.
Split on 17 and 20
- Profit if it wins
- $42.50
- Back in your hand
- $45
Either 17 or 20 wins. The $2.50 covers both numbers, not $2.50 on each.
Corner on 17, 18, 20, 21
- Profit if it wins
- $20
- Back in your hand
- $22.50
Any of the four wins. The $22.50 coming back includes your $2.50 stake.
A winning bet can still lose you money
Put $10 on 17 and $1 on red: $11 on the table. If red 9 lands, the red bet wins $1 but the $10 on 17 is gone, so the spin costs you $9. On 18 of 37 numbers this layout pays something and still leaves you down.
Call bets
French Call Bets, Priced Up
Call bets cover a slice of the wheel rather than a block of the table. Online, you'll usually find them on a racetrack beside the layout. Here's what each one costs with $1 chips, and how often it pays.
Tiers du Cylindre

Popular Roulette Systems, Run Through the Calculator
James Bond, two dozens and the 3/2 system all win more often than red or black, and all three cost exactly the same on average. A layout can win most spins and still lose money, because the losing spins are bigger. The five-number bet is here as a warning.
| Layout | Stake | Wins | Best spin | Worst spin | Average cost a spin | Try it |
|---|---|---|---|---|---|---|
| James BondA $200 split across 19 to 36, the six line 13 to 18 and zero. It wins on 25 numbers, but 1 to 12 costs the full $200. | $200Single zero | 67.6% | +$160 | −$200 | $5.412.70% | |
| Two dozensTwo dozens cover 24 numbers. You win $10 about two spins in three and lose $20 the rest of the time. | $20Single zero | 64.9% | +$10 | −$20 | $0.542.70% | |
| 3/2 system$15 on red and $10 on the second column, which has 8 black numbers. Most wins are just $5. | $25Single zero | 70.3% | +$35 | −$25 | $0.682.70% | |
| Five-number betThe only bet with a different house edge on a standard table: 7.89%, against 5.26% for everything else. | $5Double zero | 13.2% | +$30 | −$5 | $0.397.89% |
Loading a system uses your current chip value, so the stake scales with it. Progressions such as the Martingale change the stake after each spin rather than the layout; our roulette strategies guide covers them.
The wheel
Why the Wheel Changes the Cost
The payouts are the same on every wheel. What changes is how many pockets there are, and that's where the house edge comes from.
European
2.70%
37 pockets with one zero. $100 of bets costs $2.70 on average, whichever bets you choose.
American
5.26%
38 pockets with 0 and 00. The same $100 costs $5.26, and the five-number bet costs $7.89.
French
1.35%
The European wheel plus La Partage: half your even-money stake back on zero. Other bets stay at 2.70%.

The math
How the Calculator Works
Every pocket on the wheel is equally likely, so the calculator works out what your layout pays on each one and adds them up. No guessing and no simulated spins, except for the many-spin range.
- Profit on a winning bet
- Stake × payout. A $5 split pays $5 × 17 = $85.
- Result on a number
- Everything your winning bets return, stakes included, minus everything on the table.
- Chance of finishing ahead
- Numbers with a positive result ÷ pockets on the wheel (37 or 38).
- Average cost per spin
- The average result across every pocket, which always comes to the house edge × your total stake.
- House edge
- 1 − (numbers covered ÷ pockets) × (payout + 1). For a straight on a single-zero wheel: 1 − 36/37 = 2.70%.
Roulette Calculator FAQs
How do I use the roulette calculator?
Pick a chip and tap the table to place it: a number, a line between numbers for a split, a corner where four numbers meet, or any outside bet. The calculator shows what every number would pay you, your chance of finishing the spin ahead, the average cost per spin and which live tables take your total stake.
Does a 35 to 1 payout include my stake?
No. 35 to 1 means 35 dollars of profit for every dollar staked, and the winning stake comes back on top. A $1 straight bet that hits returns $36 in total.
Can a winning bet still lose me money?
Yes, when you have several bets on the table. Put $10 on 17 and $1 on red, and if red 9 lands the red bet pays $1 but the $10 on 17 is gone, so the spin costs you $9. The calculator marks these numbers in amber.
Which roulette bet has the best odds?
On a standard single-zero wheel every bet has the same 2.70% house edge, so none is better value. Red or black wins most often, at 48.65% of spins. French roulette with La Partage cuts the edge on even-money bets to 1.35%, and the five-number bet on a double-zero table is the worst at 7.89%.
Does covering more numbers improve my odds?
It raises how often you win, not what the game costs you. Covering 30 numbers wins on most spins, but the losing spins cost more than the winning ones pay, so the average loss stays at the house edge.
How much does a Voisins du Zéro bet cost?
Nine chips: two on the trio 0, 2, 3, two on the corner 25, 26, 28, 29 and one each on five splits. It covers 17 numbers, wins on 45.9% of spins and costs 2.70% of what you bet on average, like every other bet on a single-zero wheel.
Does the calculator work for live roulette?
Yes, for live tables with standard payouts. Multiplier games such as Lightning-style roulette pay less on a normal number to fund the multipliers, so they need their own math.
Can the calculator predict the next spin?
No. Every spin is independent, and past results don't change the next one. The calculator tells you what a layout pays and how often, not where the ball will land.
