# Sports Betting Odds Calculator

Our betting odds calculator is perfect for showing you how to calculate potential winnings for all types of sports bets. It indicates how much you'd win based on the odds and total wagered. That way, you’ll know the exact amount you'd win before placing any picks from your favorite sportsbook.

e.g. 100

e.g. -110

e.g. 2.0

e.g. 1/1

e.g. 50%

## Why are Betting Odds Important?

Before making any bet it's important to know what you're risking and the expected payout on that wager.

You might be able to guess what the payout could be based on the odds but in case you can't do the math (or don't want to) our betting odds calculator can do the work for you.

## How to Use Our Betting Odds Calculator

Step 1:
Enter your odds. Our calculator supports all major formats:

Most betting sites offer each odds option. It’s entirely up to you which type you prefer. We use the American style here.

Step 2:
Enter the amount of money you wish to bet. Our calculator will take care of the rest. You’ll see how much money you’ll win, and the total payout you’d receive. We set the bet amount to \$100, but you can enter any amount you want as long as your bankroll can handle it.

## Format Definitions: Odds and Probabilities

There are three methods of stating odds that most bookmakers and websites support. But there's also a fourth- implied probability - that is also useful when evaluating a bet or checking how likely an outcome is.

### American Odds

Positive Figures (+): The odds state the winnings on a \$100 bet. Ex: American odds of +120 would win \$120 on a \$100 bet.

Negative Figures (-): The odds indicate how much must be bet to win \$100 profit. Ex: American odds of -120 would win \$100 on a \$120 bet.

### Decimal Odds

Decimals quote the potential return if the bet succeeds, relative to the stake. If \$10 is bet at odds of 4, the total returned is \$40 (\$10 x 4) and the potential profit is \$30 (\$10 x 4 minus the \$10 stake).

### Fractional Odds

Used mostly in the United Kingdom and Ireland, fractions quote the potential profit if the bet succeeds, relative to the stake. If \$10 is bet at odds of 3/1, the potential profit is \$30 (\$10 x 3) and the total returned is \$40 (\$30 plus the \$10 stake).

### Implied Probability

Odds can be converted into probability. A 4/1 bet is expected to win one in every five attempts, therefore the probability is 20%.

### Using Moneyline Odds

The moneyline is one of the most common bets. This is a straight-up bet. All you need to do is pick the winning team.

Let’s say you want to bet on an NBA game. The odds would look something like this:

Boston vs New York: Moneyline
TeamOdds
Boston CelticsEVEN
New York Knicks-120

## Totals

Totals or OVER/UNDER betting is when you wager on the combined score of the two teams competing in any given game, and whether the total will be OVER or UNDER the sportsbook’s prediction.

The amount that is set by the oddsmakers is based on how they foresee a game unfolding from a scoring perspective.

At betting sites, Totals bets would look something like this:

Boston vs New York: Total
OptionOdds
OVER 104.5-110
UNDER 104.5-110

You would type -110 in the American Odds section to see how much you’d win based on the amount wagered. If you believe the combined score for both teams will be 105 points or more, you would bet the OVER. If you think the combined score for both teams will be 104 points or less, you would bet the UNDER.

### Point Spreads: Which Team Will Cover?

The odds would look like so:

Boston vs New York: Point Spread
OptionOdds
Boston +3.5-115
New York -3.5-105

Prop betting is a wager based on occurrences or non-occurrences during a game or season. These incidents may not correlate with the outcome of a game or even the final score unlike point spreads, totals or straight-up bets.

Props are what we call novelty bets because they can consist of individual player or team milestones, and will appear like so at betting sites:

James Harden - Total Points Scored (30.5)
OptionOdds
OVER 30.5 Points-115
UNDER 30.5 Points-115

In this player prop, you’re betting on the number of points that James Harden will score in a game. You can bet OVER or UNDER the oddsmaker’s line of 30.5 points for The Beard.

If you bet OVER 30.5 and Harden scores 31 or more points, then your bet wins. If he doesn’t, it loses.

If you bet UNDER 30.5 and Harden scores 30 points or less, your bet wins. If he scores more, your bet loses.

### Futures

The futures wager is ideal if you’re looking to make long-term bets. For example, in the NBA a future bet would be who you believe is going to hoist the Larry O’Brien Championship Trophy. With our sports betting calculator, you enter their odds in the American Odds section to see the potential payout.

Los Angeles Lakers +200
Milwaukee Bucks+225
Los Angeles Clippers+300
Boston Celtics+1500
Houston Rockets+1500
Toronto Raptors+1600
Denver Nuggets +2200

Our odds calculator can compute just about everything, including live betting. Live betting lets you wager while the game is going on, for instance to bet on who will score next. However, parlays (more than one bet on a ticket) have a separate betting calculator for more intricate wagers, which allows you to input the odds for each leg of your parlay to quickly calculate the payout of your bet.
