How to Use an Odds Calculator

No matter the type of bet you’re making, our calculator has you covered. First, you’ll need to enter your odds. The calculator offers four options: American (-500), Decimal (1.20), Fractional (1/5) and Implied (83.3%). The majority of betting sites offer each odds type, so it’s up to you to decide which you like best. Here at Odds Shark, we use the American style.

Next, enter the budgeted amount you want to bet with and our calculator will determine how much money you’ll win, and the total payout you’d receive. We have it set to $100, but you can input any amount you wish. Just make sure your bankroll can handle it.

Sports Betting Odds Calculator: Using Moneyline Odds

One of the most common bets is the moneyline. This is a straight-up (SU) bet where you would simply pick a winner. Let’s say you want to make a college basketball wager on March Madness.

The odds would look something like this:

Duke vs Syracuse: Moneyline
If you want to lay down $50 on the Syracuse to win, you would input -120 in the American Odds section and 50 in the Bet Amount ($) section. You’ll see that you’d get a payout of $91.67 – your original $50 comes back along with your winnings of $41.67.

On the other hand, if you take that same $50 and put it on the Duke, you would input +100 (EVEN) in the American Odds area and 50 in the Bet Amount ($) space. Your payout would be $100 – you get your $50 back, coupled with your winnings of $50.

Totals, Point Spreads and Prop Odds

Besides SU bets, you can use our calculator tool for other gambling options.

Totals bets will be listed like this at the sportsbook:

Duke vs Syracuse: Total
OVER 54.5-110
UNDER 54.5-110

In this case you would use the -110 to see how much you’d win based on the amount wagered.

For point spread bets, the odds would look like so:

Duke vs Syracuse: Point Spread
Duke +1.5-115
Syracuse -1.5-105
Here, you’d use -115 if you believe Duke will cover, or -105 for the Syracuse to cover.

Props will appear like so at the betting site:

Which team will Win the National Title?
Kansas +600
San Diego State+1250
Louisville +1600

For this scenario, you would pick the team you believe is going to win the entire March Madness Tournament, and input their odds.

You can also use this calculating tool for live betting and futures bets. Parlays are more intricate bets. We have a separate betting calculator for those.
