Welcome to the world of roulette, where fortune and strategy collide to create an unparalleled casino experience. Whether you’re a well-seasoned player or you’re just starting out, you’ll know that success in roulette calls for more than a little luck. That’s where a roulette calculator comes in. 

In this guide, we’ll take a closer look at what a roulette calculator is, where you can find one and how you can calculate the best odds. By the time you’re finished reading, you’ll be equipped with everything you need to excel playing live or online roulette at a casino. 

What Is a Roulette Calculator?

Today, there are endless tools out there claiming to improve the experience and outcome of online casino games, so what makes a roulette calculator any different? 

Unlike other tools that offer a wide range of general functions that provide general results, the roulette calculator specializes in precise calculations and insights specifically tailored to the game of roulette.

Essentially, it uses complex mathematical algorithms to analyze the odds of different betting strategies and scenarios in real-time. This arms the player with data that will help them make smarter betting choices. Because of this, they can maximize the potential of each spin and reduce the risk of losing large amounts of money.

By using a roulette calculator, seasoned players and newcomers alike can elevate their gameplay to new heights, optimizing their chances of winning big.

Where To Find a Roulette Calculator

Now that you know what a roulette calculator is and why it’s advantageous to have 

one on your side when playing, the next step is finding the calculator for you. So, where exactly can you find this game-optimizing tool?

Look Online

There are many websites that offer roulette calculators. Some of these calculators are free to use, while others ask for a small subscription fee. Sites where you can play at a casino online and that offer live dealer casino games very often have built-in calculators that help you calculate the odds of each of your bets.

In Casinos

Some casinos offer roulette calculators to their players, usually located at the roulette tables.

Using software

For a more personalized approach, you could download software to use live or offline. This kind of software is available from third-party websites and downloadable on your mobile device or computer. 

Which factors should you consider when choosing a calculator?


The calculator should be reliable, accurate and from a reputable source. It should also be completely up-to-date with the latest strategies and odds calculations.

Ease of Use

The calculator should offer a smooth, simple experience for the player and be easy to navigate and understand.


The calculator should have the features you actually need, such as the ability to calculate the odds, payouts and any expected returns.

It’s important to remember that no roulette calculator can guarantee a win. Roulette is a game of chance, so there’s always the possibility of losing.

Fun fact: Interestingly enough, roulette is not the only game to boast its own calculator. Variety games, like jackpot slots, have their own calculators and strategy guides to aid players in making the best possible decisions when playing.

How to Calculate Roulette Odds

To improve your chances of success, understanding how the odds work in roulette is crucial. The first thing to know is that roulette can be played in different ways, from classic European and American versions to more modern adaptations, which often include fun bonus features. Each bet made in the game has varying odds based on its number of potential outcomes.

You’ll then need to familiarize yourself with the different betting options, such as the popular but risky straight-up bet (betting on a single number,) split bets (betting on two adjacent numbers,) corner bets (betting on four numbers forming a square) and red/black bets. From there, you can assess the probability of each of your bets.

For instance, a straight-up bet on a single number in European roulette has a 1 in 37 chance of winning, which translates to odds of 35:1. Betting on black or red gives you nearly a 50/50 chance with odds of 1:1.

After you’ve done those sums, you can begin to calculate your payout. What you need to know here is that each bet type has a corresponding payout ratio. For instance, a straight-up bet typically pays out at 35:1, meaning if you win, you’ll receive 35 times your initial bet.

Or, you could save your time and effort by using a roulette calculator, eliminating the need for any manual calculations and allowing you to fully focus on enjoying the game. Simply enter your desired bet and amount. Then, allow the calculator to work out the probability of your winning and the potential payout.

Tip: Consider using the concept of units in roulette. This represents the amount you’ve wagered per spin. Giving a unit value to each bet will help you make smarter betting decisions and manage your bankroll more effectively.
