Every roulette bet has an exact mathematical payout, a precise win probability, and a house edge that never changes, regardless of what happened on the last spin. This free roulette calculator shows you all three for every bet type, across all three major variants played at Canadian online casinos.

The expected loss panel below calculates your projected session cost based on stake, spin rate, and hours of play. The comparison panel shows the same bet across all three variants side by side so you can see exactly what each wheel costs you.
How to Use This Roulette Calculator
Our Maple Casino roulette calculator is one of many helpful online casino tools we offer. It has four inputs that update in real time as you type. You can use it as a roulette payout calculator to check what a winning bet would return, a roulette odds calculator to compare bet probabilities, or a roulette winnings calculator to see the difference between total return and net profit. To use it, simply:
- Select your roulette variant. Using the three tabs at the top to select your preferred variant. European and French both use a 37-pocket single-zero wheel. Here, the difference is the La Partage rule on French tables, which halves the house edge on even-money bets. American uses a 38-pocket double-zero wheel.
- Enter your stake. In the field provided, insert the amount you would like to bet. This calculator handles any stake from $0.10 to $10,000.
- Choose your bet type from the grid. All standard inside and outside bets are covered, plus the Five-Number bet (American only). The currently selected bet is highlighted in red.
- Use the Expected Loss Calculator below the results. Enter your typical spins per hour and planned session length. Our tool calculates your mathematical expected loss for that session based on the current bet’s house edge.
The comparison panel below the results always shows the same selected bet across all three variants simultaneously. This is the most direct way to see why variant selection matters more than bet selection.

The Three Roulette Variants Available at Canadian Online Casinos
You’ll run into three roulette variants at Canadian online casinos, and telling them apart is the single most useful thing you can do before placing a bet. For the full details behind why, see our roulette strategy guide.
European Roulette — The Canadian default
A 37-pocket wheel (1–36 plus a single green zero) with a 2.70% house edge. This is the default at most licensed Canadian platforms. If you haven’t checked which variant you’re on, you’re probably already playing it. When our team checks a new casino, European is usually what loads first. The American version only shows up as a secondary option, if at all.
French Roulette with La Partage — The best odds available
This online casino game features the same wheel as the European, but the La Partage rule returns half your stake on even-money bets (Red/Black, Odd/Even, High/Low) when the ball lands on zero. This cuts the house edge to 1.35%, the lowest available on any standard table. It’s worth the extra few seconds to check the game rules for a La Partage or En Prison label before you sit down. Use the comparison panel above to see exactly what that edge difference is worth on your stake.
American Roulette — The one to avoid
The extra 00 pocket pushes the house edge of this particular variant to 5.26%, and as high as 7.89% on the Five-Number bet (the worst bet on the table). The payouts look the same as European, but you’re being paid 37-pocket odds on a 38-pocket wheel. If European or French is available on the same platform – which it almost always is in Canada – there’s no situation where American is the better pick.
Roulette variant comparison — house edge at a glance
| Variant | House Edge (standard bets) | House Edge (even-money bets) |
| French (La Partage) | 2.70% | 1.35% (Best available) |
| European | 2.70% | 2.70% |
| American | 5.26% | 5.26% |
| American (Five-Number bet) | 7.89% | n/a — (Best to avoid entirely) |
All the figures listed here apply to a standard, properly licensed RNG or live dealer roulette table. The house edge is fixed and cannot be changed by betting patterns, strategy systems, or previous outcomes.
What is the difference between payout and profit in roulette?
Payout is the total amount returned to you after a winning bet, including your original stake. Profit is the amount you win after subtracting your stake.
For example, a $10 straight-up roulette bet at 35:1 would return $360 in total: $350 in profit plus your original $10 stake. This calculator separates payout and profit so the result is easier to understand.
How We Developed This Roulette Calculator
We didn’t build this roulette calculator from a spreadsheet alone. It came out of independent testing, repeated play, and dozens of small details you only notice when you’ve spent real time at the tables.
Our reviewers tested roulette games across a range of sites and providers. We looked at how the games behave in real sessions. From discussing how quickly a bankroll can move, how table limits affect bet choices, how different roulette variants change the risk, all to how easy it is for players to understand what they are putting on the line. We considered it all.
To Maple Casino, this Canadian testing perspective matters. The result is a tool shaped by real roulette sessions, not just generic odds. It is designed to help Canadian players compare bets, understand potential outcomes, and make more informed decisions before they spin.
How to Use the Expected Loss Calculator
The expected loss calculator is the most practically useful feature on this page for anyone playing roulette at a Canadian online casino or visiting a land-based casino.
It answers the question every player should ask before sitting down: given my stake, how often I plan to bet, and how long I plan to play, and what is this session expected to cost me mathematically?
The calculation is: Stake × Spins per Hour × Hours × House Edge = Expected Loss. Do keep in mind that the result is a theoretical long-run average, not a guaranteed outcome for any given session. Short sessions produce highly variable results. But over many sessions, actual results cluster around this figure.
| Example session | Expected loss calculation |
| $25 stake x 40 spins/hr x 2 hrs x European (2.70%) | = $54.00 expected loss |
| $25 stake x 40 spins/hr x 2 hrs x French even-money (1.35%) | = $27.00 expected loss |
| $25 stake x 40 spins/hr x 2 hrs x American (5.26%) | = $105.20 expected loss |
| $10 stake x 30 spins/hr x 1 hr x European (2.70%) | = $8.10 expected loss |
| $50 stake x 50 spins/hr x 3 hrs x American (5.26%) | = $394.50 expected loss |
Use the expected loss figure as a session budget anchor, not as a guarantee. If you’re comfortable treating $54 as an entertainment cost for a two-hour session, European roulette at $25/spin is calibrated to that. If that figure is uncomfortable, reduce the stake or session length until it’s in a range you’re comfortable with. Our responsible gambling page covers session management in more detail.
Roulette at Canadian Online Casinos in 2026
Canadian roulette players have more choice than ever, but the basics still come down to the same question: what are you risking, and what can the bet realistically return?
That is why this calculator focuses on standard roulette math, first and foremost. Whether you are playing a $1 inside number, spreading $25 across red and a dozen, or comparing European and American wheels before a live dealer session – this tool shows the odds, payouts, and potential returns before you commit your bankroll.
The Canadian context matters too. Many online roulette players here play in CAD, use shorter mobile sessions, and move between regular RNG tables and live dealer games. Roulette is part of a much bigger Canadian online casino habit, which makes understanding the numbers behind each spin even more important.
Live Dealer Roulette and Lightning Roulette in Canada
Live dealer roulette is one of the fastest-growing segments in Canadian online gambling. Evolution Gaming (which supplies live tables to virtually every major operator in Canada) runs live European, French, and American roulette, plus specialist variants.
Lightning Roulette deserves specific mention because it changes the base maths in a way that isn’t always obvious. Standard straight-up bets on Lightning Roulette pay 29:1 rather than 35:1. The reduced payout funds the RNG multipliers (50x to 500x) that appear on randomly selected numbers each round. The overall RTP of Lightning Roulette is approximately 97.30%, compared to 97.30% for standard European roulette. The RTPs are essentially equivalent, but the payout structure is dramatically different.
This calculator covers standard roulette maths (the Lightning Roulette straight-up payout of 29:1 is not reflected here). If you are specifically calculating Lightning Roulette returns, use 29 as your straight-up payout ratio rather than 35.
Five Roulette Decisions Our Reviewers Pay Attention To
Roulette is a game of chance, and no betting system or calculator can remove the house edge or guarantee a profit. That said, some choices do affect the expected cost of play. When our reviewers tested roulette games in order to develop this roulette payout calculator, these are the five practical factors they prioritized.
1. Choose European or French roulette when available
The wheel format matters. European and French roulette use a single zero, while American roulette adds a double zero. That extra pocket increases the house edge, which means the expected cost per dollar wagered is higher over time. For players comparing tables, the single-zero versions are generally the more favourable option. Don’t believe us? Input the same values in the Roulette calculator and switch between formats. The math speaks for itself.
2. Understand when La Partage applies on French roulette
French roulette can offer one of the lowest standard house edges in the game, but only on specific bet types. The La Partage rule usually applies to even-money bets such as Red/Black, Odd/Even, and High/Low. If the ball lands on zero, the player receives half of the even-money stake back. Our reviewers check whether this rule is clearly available before treating a French roulette table as more player-friendly. Don’t worry, our online roulette calculator takes this into account.
3. Set a session budget before playing
This roulette bet calculator is most useful before a session starts. It can help you estimate how much you are putting at risk based on your stake size, bet type, and planned number of spins. Our reviewers treat this as a bankroll-awareness tool, not a prediction tool. If the expected cost does not fit within a your entertainment budget, the safer move is to reduce the stake, shorten the session, or not play.
4. Do not rely on betting systems to change the odds
Systems such as Martingale, Fibonacci, D’Alembert, and Labouchere can change the pattern of wins and losses, but they do not change the odds of the wheel. Each spin is independent, and the house edge remains built into the game. Our reviewers do not treat betting systems as roulette strategies, they treat them as staking patterns that can increase risk, especially when table limits or bankroll limits are reached.
Responsible Roulette Play Starts With Knowing the Numbers
This roulette calculator is designed to help you understand risk before a session starts. It can show potential payouts, win probabilities, house edge, and estimated session cost, but it cannot predict results or reduce the randomness of the game.
Set a budget before you play, only gamble with money you can afford to lose, and avoid increasing your stake to recover losses. If roulette stops feeling like entertainment, take a break. Players in Canada can also use safer-play resources such as the Canadian Centre on Substance Use and Addiction’s Lower-Risk Gambling Guidelines if you want practical guidance on keeping gambling within lower-risk limits.

Roulette Odds Calculator FAQ
This roulette calculator helps you estimate the numbers behind a roulette bet before you place it. Enter your stake, choose a variant, and select a bet type to see the potential payout, profit, win probability, and house edge.
Start by entering the amount you want to bet. Then choose the roulette version you are calculating for, such as European, American, or French roulette with La Partage. After that, select the bet type: straight-up, split, street, corner, dozen, column, red/black, odd/even, high/low, or another standard roulette wager. The calculator will show what the bet pays if it wins, how much profit you would make, and the probability of that result based on the wheel you selected.
Yes, but only in a mathematical sense. The calculator shows the probability of a selected bet winning based on the number of pockets covered on the wheel.
For example, a straight-up bet covers one number. On a European wheel, that means 1 winning pocket out of 37. On an American wheel, it is 1 out of 38 because of the added double zero. The calculator uses those wheel odds to show the chance of each bet type winning. See our RTP and house edge guide for a more detailed breakdown of how these numbers work in practice.
Yes. The calculator can be used for standard online roulette games available to Canadian players, including European, American, and French roulette. It is especially useful for comparing bets before playing with Canadian dollars, because you can enter your own stake and see the estimated payout, profit, and expected cost. The calculator is designed for standard roulette rules. Some live dealer or multiplier games may use modified payouts, so always check the paytable inside the game before relying on the result.
No. This roulette win calculator does not predict outcomes, track live spin data, or identify “due” numbers. Roulette is a random game, and each spin is independent. The calculator is designed to show the fixed maths behind a bet: how much it can pay, how likely it is to win, and what the house edge is. It cannot tell you where the ball will land next.
It works for live dealer roulette when the table uses standard European, American, or French roulette payouts. Many live dealer roulette games follow standard payout rules, so the calculator can help estimate returns before you play. For modified games, such as Lightning Roulette or other multiplier versions, payouts may differ from standard roulette. In those cases, use the calculator as a general reference and check the game’s own paytable for exact returns.
Yes. A roulette probability calculator focuses on the likelihood of a bet winning, while a roulette payout calculator focuses on what the bet pays. This tool combines both. It shows the win probability, payout, profit, and house edge in one place so you do not have to calculate each figure separately.
A roulette wheel odds calculator compares your bet against the structure of the wheel. European and French roulette wheels have 37 pockets: numbers 1–36 plus a single zero. American roulette has 38 pockets because it includes both 0 and 00.
That extra pocket changes the odds and increases the house edge. This calculator adjusts the probability and expected return based on the wheel type you choose.
The roulette variant changes the number of pockets on the wheel and, in some cases, the rules applied to certain bets. European roulette has one zero, American roulette has one zero and one double zero, and French roulette may include La Partage on even-money bets. Because the number of possible outcomes changes, the calculator adjusts the win probability and house edge for the variant you select.
Even-money bets such as red/black, odd/even, and high/low cover the most numbers, so they have the highest win probability among standard roulette bets. They usually pay 1:1 because the chance of winning is higher than inside bets such as straight-up numbers or splits. A higher chance of winning does not mean the bet removes the house edge. The calculator shows both the probability and payout so you can see the trade-off clearly.
