Standard roulette bet types each have a fixed payout ratio set by the game’s own rules — this calculates the winnings for a chosen bet type and amount.
How it works
The bet amount is multiplied by the selected bet type’s payout odds to give the winnings; adding the original bet back gives the total amount returned.
What this does not include
This does not include the probability of winning each bet type — this calculator specifically computes the payout if the bet wins, not the odds of that happening.
How to use this calculator
- Select the bet type and enter the bet amount.
A worked example
A $10 straight-up bet (single number, 35:1 payout): winnings = $350, total returned = $360 (winnings plus the original bet).
A $10 even-money bet (red/black, 1:1 payout): winnings = $10, total returned = $20.
What the variables mean
| Variable | Meaning |
|---|---|
| Bet type | Which roulette bet is being placed, each with its own fixed payout ratio |
| Bet amount | Amount wagered |
Edge cases worth knowing
A higher payout ratio always comes with lower odds of winning. A straight-up bet pays 35:1 precisely because hitting one specific number out of 37 or 38 is far less likely than a roughly 50/50 even-money bet.
Total returned includes the original bet, while payout (winnings) does not — a distinction that matters for calculating actual profit versus total chips received back.
Frequently asked questions
Why does a straight-up bet pay so much more than red/black?
A straight-up bet on a single number has a much lower chance of winning (1 in 37 or 38, depending on the wheel), so the payout is correspondingly higher to balance the odds.
Are these payout odds the same at every casino?
Standard roulette payout odds are essentially universal across casinos, since they’re defined by the game’s own rules rather than set individually by each venue.
What’s the difference between American and European roulette payouts?
The payout odds themselves are identical; the difference between American and European roulette is the number of pockets on the wheel (and therefore the underlying win probability), not the payout ratios.
