The roulette payout and odds calculator instantly shows your potential profit, winning probability, and wheel coverage before you risk a single dollar. The European roulette is selected by default.
Place bets on the interactive board, pick a chip value from $1 to $500, and hit Calculate. Works for European, American, and Triple 0 wheels.
The roulette payout & odds calculator walks you through a simple setup process before showing your results.
After clicking Calculate, the roulette payout and odds calculator generates four panels, each covering a different angle of your betting strategy:
Please Note
The calculator uses true mathematical probabilities based on the wheel type you selected. European odds differ from American odds because of the extra zero pocket.
Once the roulette payout and odds calculator runs, an “Edit Bets” button appears. Click it, and the board stays loaded with your previous bets, on top of which you can add new ones. Two controls become available: Restart and Undo.
Restart (labelled with an X icon) clears everything: all bets, all results, all panels. The board returns to its initial state.
Undo removes your last single action. It stays greyed out when you first enter edit mode and only activates after you’ve added a new action. It applies only to actions taken since the last Calculate. You can’t undo bets from a previous calculation.
The result panels stay visible as a snapshot of your last calculation until you hit Calculate again.
Switching the wheel variant works the same way: the board updates immediately, and all odds, probabilities, and expected values recalculate based on the new pocket count.
Recommendation
Always practice your betting strategy on European roulette first. The lower house edge means your bankroll lasts longer across the same number of spins.
The roulette payout and odds calculator gives you a full picture of any betting strategy before a single chip hits the table. Run different combinations, switch wheel variants, and compare how inside bets stack up against outside bets on coverage and potential profit.
You can test inside bets like straight-ups and splits against outside bets like dozens and columns. Compare how much coverage you get versus potential profit. Run calculations for different chip values to see how bet sizing affects your overall strategy.
Once you know your numbers, a few other tools are worth adding to your practice routine:
This chart displays the numbers currently covered by your bets. Orange-highlighted sections indicate active bets. Greater orange coverage means a higher chance of hitting a winning number.
This table displays the payout, odds, expected value and profit for every single bet on your layout if that bet hits.
Bet: The specific wager you placed (for example, Straight on 7 or Split on 2–5).
Amount: How much you staked on that particular bet.
Odds: The statistical likelihood of a hit. If the odds are 1 in 37, you can expect this outcome to appear about once in 37 spins over time.
Payout: The standard roulette payout ratio for that type of bet.
Expected Value (EV): The average result of this bet in the long run, based on the house edge and your stake. Negative values represent an expected loss.
Profit: The net amount you would gain if this bet wins, not counting your original stake.
