Using an odds calculator may seem excessive to some beginners, but in reality, it’s commonplace for many online sportsbook users. A betting odds calculator allows users to input their stake & odds format they desire (American, Decimal, or Fractional) and quickly calculates the potential return of bets made.

A bet calculator is ideal for providing an accurate idea of the bettors’ potential winnings for all types of sports wagers, including standard single bets, using the three different odd types. The calculator will show bettors how much they can win based on the odds and total sum wagered.

It’s a great tool to use, as it gives bettors an exact amount they can win before even placing a bet. In this article, we will delve deep into how to use a betting calculator and show bettors how to get all the data they need to make the best value wagers today!

Betting Odds Calculator

Using a sports betting calculator is a basic betting procedure, with bettors of all abilities using them these days. There are some basic steps bettors should take if they’re going to start using an odds payout calculator, which look like this:

– Enter the odds using one of the various formats; American Odds (-400), Decimal Odds (1.25), Fractional Odds (1/4), Implied Probability (80%). Bettors will often have to go with whatever odds format is on offer from their sportsbooks provider. It’s commonplace for providers to offer all three, but it really depends where you are in the world.

– Enter the stake. The calculator will handle the rest for you. It will inform the bettor of how much they’ll win, including details of the total potential payout. Normally these calculators are set to a value of $100, but this figure can, of course, be changed.

There are three methods of defining the odds that are frequent among bookmakers. Implied probability is also used when evaluating a bet or checking the likelihood of the estimated outcome.

What are American Odds?

American odds are the default odds used by sportsbooks based in the states. The odds bettors will see use a ‘-’ sign to represent the favorite and a ‘+’ sign to show the underdog/s. All bets are based on winning $100.

An example of this would be if a bettor puts $100 on the Mavs to win the NBA Finals. If the odds are -140 for the Mavs against the Suns, that means Dallas is the slight favorite. A bettor would need to stake $140 to win $100 on the packers. If you look at underdog odds, the ‘+’ sign represents the profit you can make for every $100 wagered. Just to say, if you’re unfamiliar with any of the betting language being used here, take a look at our complete glossary of betting terms.

What are Decimal Odds?

Outside of the U.S., the vast majority of online sportsbooks and land-based betting facilities use Decimal odds. Decimal odds show the amount that a bettor can win for every $1 staked. The number indicates the total return for the better, not just the profit as is seen in the other two odd formats.

Here’s an example: The Stars are 1.714 in decimal odds (-140 in American). For every $1 wagered, the bettor profits 71.4 cents, plus the original stake of $1. The Oilers have odds of 2.2 in decimal odds (+120 in American), which means every $1 bet would profit $1.20 plus the original $1 stake.

What are Fractional Odds?

Finally, we come to Fractional odds, which are typically used in the UK and Ireland. It’s uncommon for bettors to use fractional odds for sports betting, other than in racebooks, where it’s frequently used, because making conversions in your head is tough.

As we mentioned, the calculation is a little more difficult. Multiply your bet by the top number, then divide the figure by the bottom number. As such, a $10 bet at 5/2 odds is (10×5) / 2, which pays out at $25. A $10 bet at ⅖ odds is (10×2), which pays out $4.

Implied Odds

Another common thing to see when using an odds payout calculator is an implied odds option. This means, the odds correlate to the probability of a certain team winning, or outcome happening. Using the example from before, a -140 favorite has roughly a 58.3% chance of winning, while a +120 underdog has a 45.4% chance of success.

In each circumstance, you’ll notice the figures total more than 100%. That’s what is known as vigorish (vig, juice), which is the sportsbooks cut. A betting calculator can also assess the value of a bet by calculating the vig.
