Roulette Payout Calculator: Winnings, Win Chance and Expected Loss
Quick answer
A winning roulette bet returns your stake times (payout + 1): 10 USDT on red returns 20 USDT, and 10 USDT on a single number returns 360 USDT. On a single-zero wheel red wins 48.65% of spins, and every standard bet has the same 2.70% house edge, so the expected loss on 10 USDT is about 0.27 USDT.
| Total returned on a win | stake × (payout + 1) |
|---|---|
| Win chance | numbers covered ÷ pockets on the wheel |
| House edge, European (37 pockets) | 2.70% on every standard bet |
| House edge, American (38 pockets) | 5.26%; five-number bet 7.89% |
| House edge, triple zero (39 pockets) | 7.69% |
Use this roulette payout calculator to see exactly what a bet pays, how often it wins and what it costs you on average. Choose the wheel, add up to three bets with their stakes, and the calculator works out the payout, win chance and expected value of each, plus the house edge of the whole combination.
The default is 10 USDT on red at a single-zero wheel. A win returns 20 USDT (10 profit plus your stake), it happens 48.65% of the time, and the expected value is a loss of about 0.27 USDT per spin.
How this is calculated
Roulette payouts are quoted as "X to 1": you win X times your stake and keep the stake, so the total returned is stake × (X + 1). The win chance is the count of numbers the bet covers divided by the number of pockets.
returned = stake × (payout + 1) win chance p = numbers ÷ pockets expected value = stake × (p × (payout + 1) − 1)House edge of a combination = −(sum of expected values) ÷ total stake.
Worked example: 10 USDT on red plus 5 USDT on a single number, European wheel.
- Red: p = 18 ÷ 37 = 48.65%. EV = 10 × (0.4865 × 2 − 1) = −0.270 USDT
- Single number: p = 1 ÷ 37 = 2.70%. EV = 5 × (36 ÷ 37 − 1) = −0.135 USDT
- Total stake 15 USDT, expected loss 0.405 USDT, house edge 0.405 ÷ 15 = 2.70%
Expected values simply add up, so the combination has the same 2.70% edge whether or not the bets overlap. What overlap changes is how often you win something on a spin, which this calculator doesn't model because it doesn't know which numbers you picked.
Roulette payouts and win chances by wheel
Every bet type, with the win chance on each wheel from our exact roulette calculations:
| Bet | Numbers | Payout | European | American | Triple zero |
|---|---|---|---|---|---|
| Straight up | 1 | 35 to 1 | 2.70% | 2.63% | 2.56% |
| Split | 2 | 17 to 1 | 5.41% | 5.26% | 5.13% |
| Street | 3 | 11 to 1 | 8.11% | 7.89% | 7.69% |
| Corner | 4 | 8 to 1 | 10.81% | 10.53% | 10.26% |
| Six line | 6 | 5 to 1 | 16.22% | 15.79% | 15.38% |
| Dozen / column | 12 | 2 to 1 | 32.43% | 31.58% | 30.77% |
| Red/black, odd/even, high/low | 18 | 1 to 1 | 48.65% | 47.37% | 46.15% |
| Five-number (0,00,1,2,3) | 5 | 6 to 1 | – | 13.16% | – |
| Wheel | House edge (standard bets) | Expected loss per 10 USDT bet | Per 1,000 USDT wagered |
|---|---|---|---|
| European (single zero) | 2.70% | 0.27 USDT | 27.0 USDT |
| American (double zero) | 5.26% | 0.53 USDT | 52.6 USDT |
| Triple zero | 7.69% | 0.77 USDT | 76.9 USDT |
The extra zeros are the whole story. Payouts stay the same while the pockets go from 37 to 39, so the edge climbs from 2.70% to 7.69%. The American five-number bet is worse still, at 7.89%. Our American vs European roulette comparison and triple zero roulette guide go deeper.
Choosing between bets
Since the edge is fixed by the wheel, the real choice is about volatility: how bumpy the results are.
- Even-money bets win almost half the time and pay 1 to 1. Your balance moves slowly.
- Dozens and columns win about a third of the time at 2 to 1.
- Single numbers win once in 37 spins on average at 35 to 1. Long losing runs are normal: our chance calculator shows a single number misses all of 37 spins about 36% of the time.
Our roulette risk and reward guide measures how much each bet swings, and the American roulette wheel guide explains the layout. If you'd rather play a game where you set the win chance yourself at a 1% edge, compare crypto dice. All roulette guides are in our roulette hub.

Frequently asked questions
How much does roulette pay on a single number?
A straight-up bet on one number pays 35 to 1. A 10 USDT bet that wins returns 360 USDT: 350 USDT profit plus your 10 USDT stake. The win chance is 1 in 37 on a single-zero wheel (2.70%), 1 in 38 on an American wheel and 1 in 39 on a triple-zero wheel.
What is the payout for red or black in roulette?
Red, black, odd, even, high and low all pay 1 to 1, so a 10 USDT winning bet returns 20 USDT. They cover 18 numbers, so the win chance is 18/37 (48.65%) on a single-zero wheel, 18/38 (47.37%) on a double-zero wheel and 18/39 (46.15%) on a triple-zero wheel.
Which roulette bet has the best odds?
Even-money bets have the highest win chance, but on any one wheel every standard bet has the same house edge. On a single-zero wheel that's 2.70% whether you bet red or a single number. The one exception is the American five-number bet (0, 00, 1, 2, 3), which has a higher edge of 7.89%.
Does betting on several numbers reduce the house edge?
No. The expected loss of a combination is the sum of the expected losses of each bet, so spreading chips around keeps the same edge as the wheel. Covering more numbers raises your chance of winning something on a spin, but the payouts shrink to match. The calculator shows the combined edge for any mix.
