Roulette Payout Calculator
Find the payout and win chance for a roulette bet.
Each roulette bet has a fixed payout and a win probability set by the wheel.
The math behind it
Profit = bet × payout ratio. On a 37-pocket European wheel, win chance = numbers covered ÷ 37.
Worked example
$10 straight-up win → $350 profit (2.7% chance).
