Whatever kind of bet you throw at it, our bet calculator can more than live up to the task.

A walkthrough guide of using our betting odds calculator

We’ve made sure that the calculator on this page can be accessed from the browser of any modern smartphone or tablet. So once you load it up, you just need to do the following things to see exactly how much you can win from your sports bet:

  1. Select your preferred odds format.
  2. Pick the type of bet you want to calculate.
  3. Type in the odds.
  4. Enter your betting stake.
  5. Once you have done this, the calculator should automatically show you what your potential return could be should you win your bet. Just remember that there may be additional steps to take for some of the more complicated bets such as each-way bets, parlay bets and so on.

    Examples of using this sports betting odds calculator

    Let’s have a quick look at some of the different ways that you could use our betting calculator to bet on your favorite sports. We’ve picked a moneyline bet on football with American odds, a parlay bet on basketball with decimal odds, and an each-way bet on horse racing with fractional odds as examples:

    Calculate a moneyline bet on football with American odds

    So let’s say that you were a fan of the New York Giants and you wanted to bet on your team to beat the Chicago Bears. You wanted to bet $10 and you could fire up our odds calculator that would reveal the potential payouts for betting on each team:

    TeamAmerican moneyline odds to winTotal potential returns
    New York Giants+300$40
    Chicago Bears-150$16.67

    From this, you’d see that the Giants are the underdogs and you’d have a tough time winning this bet, but get potentially more in return. Conversely, a bet on the Bears would be safer, but your returns wouldn’t be quite so impressive.

    Calculating a parlay bet on basketball with decimal odds

    For this parlay bet, you wanted to bet $5 on Oklahoma City Thunder, Los Angeles Lakers and the Houston Rockets each to win their next games in the NBA. You could simply type in the odds for each team into our calculator and see your potential returns:

    TeamOdds to win
    Oklahoma City Thunder1.50
    Los Angeles Lakers2.00
    Houston Rockets2.50

    From this, you would see that you have the potential to win a total return of $30 from your parlay bet. Just remember that parlay betting is hugely risky, and so you should be careful to only play with stakes that you don’t mind losing.

    Calculate an each-way bet on horse racing with fractional odds

    Let’s imagine that you wanted to bet on this year’s Kentucky Derby. You were thinking about backing the favorite, but weren’t totally sure whether it would win the race.

    As such, you decided to make a $10 each-way bet, and you could enter in the regular win fractional odds and the place fractional odds and the calculator would automatically calculate the potential payout for you.

    Just remember that this calculator can perform a range of other more complex bet types that are synonymous with horse racing. So that whether you want to try a Patent, Trixie, Yankee or Heinz, our calculator should more than meet the challenge.

    Expert tips for using this betting odds calculator

    We’ve made sure that our odds calculator is easy to use, but you’ll still need a little experience to make the most out of it. Check out these simple tips to get you started:

This offers you a great way to extend your betting abilities beyond standard single bets, and you could learn the appeal of most complex bet types ranging from Round Robins to Heinz bets and beyond.
