How the Roulette Calculator works

Before we go into how to use the calculator, there is an expectation that if you’re reading this, you already know how to play roulette on a basic level. If not, please check out our guide on how to play roulette first. 

Now, when it comes to using the roulette payout calculator, it couldn’t be easier. It’s simply a case of choosing the bet options you want and then letting the calculator do the maths. Let’s go through it step-by-step:

1. Select Roulette Type

The first option is to choose between European or American Roulette. It is essential that you choose one or the other as this has a significant impact on roulette odds.

European Roulette, broadly speaking, is better for the player as it only contains one ‘0’ on the roulette wheel. American Roulette contains both ‘0’ and ‘00’ meaning there are more pockets for the ball to fall in. The extra zero on the American Roulette table increases house edge and lowers the players expected value from each bet as follows:

  • European Roulette House Edge: 2.7%
  • American Roulette House Edge: 5.26%

Most online casinos offer both European Roulette and American Roulette games, so you can play either. Just remember to select the correct one at the top of the roulette payout calculator so that the sums are correct.

2. Select Roulette Bet

The roulette calculator will offer you a drop-down menu of all the main roulette bets you can place. There are 17 bet options to choose from covering all the key bets such as:

  • Single number
  • Even bets – Red/Black, Odd/Even, High/Low
  • Selected numbers – Split, Street, Corner, Double Street, Columns and Thirds

Simply select the option that you want the roulette payout calculator to work out. The type of bet you choose determines the roulette payout ratio. The more specific bets give a higher payout than those covering more numbers (see table below).  The beauty of the free roulette calculator is that you can use it over and over again choosing different bets for comparison.

3. Select Roulette Stake

The bet amount on the free online roulette calculator is an open field, meaning you can just type in the bet size of your choice. The beauty of this iconic casino game is that you can easily find both low stakes roulette and high stakes roulette in most online casinos. That means that bet limits in real money roulette stretch from as low as 1p to as high as £20,000 per spin.

On the roulette calculator, just select the bet amount you’re most comfortable with or play about with different sizes. It will help you to determine the risk associated with each bet, the expected loss and the potential payout so it’s ideal for working out your overall roulette bankroll.

4. Roulette Odds

Once you have made your three selections – roulette type, roulette bet and roulette stake – the calculator will do the work.

The roulette odds field in the calculator is shown in two ways:

  • Odds of Winning
  • Odds of Winning (%)

The first field shows you the actual odds while the second one shows the odds as a percentage. They are both the same odds just displayed in different forms.

The stake level you set will not affect the odds in any way. The roulette odds are calculated purely on the roulette type and the roulette bet you choose as this determines your mathematical chance of winning.

5. Roulette Payout / Expected Return

The final section of the roulette payout calculator displays the overall outcome from the bet choices you have selected. The two fields are as follows:

Payout – This is the actual roulette payout amount you will receive from a winning bet. It includes the win amount and the initial stake. For example, if you place a winning £10 bet on red, you will receive £10 back so the total payout is £20.  

Expected Return – This is a statistical representation of what you would be expected to win or lose on each of these bets if you placed them over and over again. Remember, every casino game has a built in house edge, so bets automatically come with a negative expected value over a long period of time. 

Roulette Bets and Payouts

Now we’ve covered how to use the free online roulette calculator, let’s briefly summarise the different types of bets, the level of risk and the payout ratio.

Roulette BetBet TypeRisk LevelPayout

Split (Two Numbers)Inside BetHigh Risk17:1

Feel free to test out these bets in the roulette calculator, try out different scenarios and find the risk level that most suits you.

Roulette Odds Explained

The roulette odds presented in the calculator are simply a mathematical formula based on the probability of winning. If we take the example of betting on one number on a European Roulette game, that means we have a one in 37 chance of winning. 

If we divide the number of winning scenarios (1) by the total number of outcomes (37) then we get our probability of winning (0.027). If we multiply that by 100 we get our percentage odds (2.7%).

Roulette Odds

If we do the same for betting on a column of 12 numbers:

Roulette Odds

That means we have a 2.7% chance of winning when we bet on a single number and a 32.43% chance of winning when we bet on a column. Of course, you don’t need to do the maths, as the roulette payout calculator already does that for you. 

Roulette House Edge Explained

When it comes to roulette house edge, there is a common misconception that betting on an evens bet such as red/black or odd/even gives a 50/50 chance of winning. However, this is inaccurate.

If we apply the above formula, then betting on red covers 18 numbers on the board:

Roulette House Edge European

Betting on red, therefore, gives a 48.65% chance of winning, not 50%. Meanwhile the casino has a 51.35% chance of winning as it could land on black or the green ‘0’.

The difference between these two numbers (51.35% and 48.65%) is 2.70% which is the House Edge for European Roulette. 

If we then apply the same mathematics to American Roulette, where there is a higher number of outcomes (38) with the double zero:

Roulette House Edge American

The player has a 47.37% chance of winning and the casino has a 52.63% chance of winning. The difference between these two numbers is 5.26% which is the house edge for American Roulette. 

You can see both of these scenarios within the roulette payout calculator and it is all calculated for you so you don’t have to worry about it. 

Roulette Calculator Tip

The Roulette Calculator works out all of the odds, expected return and payouts so you don’t have to do any of the maths! Just select your chosen bets and the let the free roulette calculator do the work.
