American Tennis Betting Odds

Tennis odds are mainly presented in American odds in North America – mainly the United States and Canada, much like how fractional and decimal odds are more predominant in Europe.

American odds are represented by a positive or negative amount, like -150 or +650 to denote the probability of winning a tennis match. The higher the number, the less likely that player will win, and the lower the negative number, the more likely that player is to win.

When it comes to tennis betting odds, the positive number represents how much you would win on a $100 bet on the match underdog, and the negative number would represent how much you’d have to bet to win $100 if you chose the favored player.

When it comes to calculating the probability of winning a tennis match – there really isn’t a rule for American odds, so it’s easier to convert your odds to decimal.

  • For positive odds (underdog tennis betting odds) let’s say +300: 1 + (odds / 100) = 1+(300/100) = 4.0
  • For negative odds (favored player’s odds) -300: 1 – (100 / 300) = 1.333

Now that you have your decimal odds, we can help you calculate your winnings and implied probability.

Decimal Tennis Betting Odds

As we mentioned, decimal tennis betting odds are way more common in Europe – and sometimes even in the United States, some sports bettors do prefer them because they’ve been around longer.

Decimal odds are your odds multiplied by your stake, then subtract your stake.

  • 9.0 odds would be calculated as (9.0 * $10) – $10 = $80 in winnings
  • 1.25 would be (1.25 * $10) = $10 = $2.50

To calculate your implied probability of winning, you essentially divide 1/decimal odds which is 1/ 9.0. This will give you an implied probability of 11.11%. Implied probability is an important part of your tennis betting strategy and will help you improve your chances of winning in the long term.

Fractional Betting Odds

Fractional betting odds will take you right back to elementary school. If you were a math whiz in school, you’re well on your way to understanding fractional tennis betting odds. If you see a fractionated number, like 10/1, this means someone has a ten to one chance of winning the match. This way, you can calculate their probability of winning the match from the fractional odds.

The formula looks like this: B/(A+B) = %

For example, if you see tennis betting odds are set for a match and a player has 9/1 odds to win, there is a 10% chance they will win the match.

  • 1/(9+1) = .10 (10%)

Or, if a player has 1/ 4 odds to win the match, that can be calculated like so – 4/(4+1) = 0.80 (80%) This player is usually favored to win.

So, how much will you win on fractional tennis betting odds? For every value on the right side of the fraction you wager, you will win the left. So 9/1 odds – for each $1 wagered, you will win $9. 1/4 odds – for each $4 wagered you win $1.

Finding the Right Sportsbook for You

Finding the right sportsbooks for you is an essential part of wagering. Just depositing with the first bookmaker you come across is not a smart move, as you never know what other betting markets you may want to play in the future.

We'd strongly advise shopping around the various bookmakers available to players and securing funds with one which offers value. Not only do we expect there to be value in the odds, but the bookmaker should be providing great bonuses and promotions on a regular occasion.

Another thing we should mention sometimes it's better to sign up with various sportsbooks, as bettors will be able to shop around various oddsmakers and find the best value in the market.

Top Online Sportsbooks for Tennis Betting

Now that you have a good grasp on the basics of tennis betting odds, we can start to look at sportsbooks, and which ones we recommend to sports bettors looking to get in on the tennis betting action.

Online sportsbooks are a convenient way to bet on tennis matches online, and many can provide a stellar customer service experience for new to professional sports bettors. Sportsbooks haven’t had the best reputation over the past decade or so, as many think they’re sketchy or untrustworthy, but we would only recommend sportsbooks we use ourselves. The sportsbooks we recommend are thoroughly researched and always have the best odds.

If you want to find the best Wimbledon bonus (in our Wimbledon odds page) or want a great loyalty program, we can help you find a sportsbook that meets your needs. Our online sportsbook reviews outline important criteria we personally look for when choosing an online sportsbook.

Sportsbooks that are secure, with a variety of deposit options and payout methods that boast great bonus options are all key criteria we focus on when reviewing a tennis betting site. Also, if you’re planning to do all of your bettings from a mobile phone you could consider a sportsbook with a mobile app for ease of use.

Most professional sports bettors have multiple accounts at a few online sportsbooks to ensure they’re getting the best tennis odds. Not all sportsbooks offer the same lines, so you can find excellent value by line shopping prior to placing a wager. Signing up at 3 or more online sportsbooks is recommended for sports bettors, regardless of the sport they plan to wager on.

There are always great tennis betting odds available, you just have to do a little research before placing your wagers - just have fun with it and as always, gamble responsibly.
