Sports betting can seem intimidating when you’re first starting out. Decimal odds, Moneylines, fractions – it’s enough to make your head spin! But understanding sportsbook odds is the key to placing smart bets and enjoying the thrill of the game.
If you’ve been scratching your head trying to figure out how odds work, this guide has got you covered. We’ll break it all down step-by-step, including the different types of odds, how to read them, and even how to calculate payouts.
What Are Sportsbook Odds?
At their core, sportsbook odds tell you two key things:
- How likely an event is to happen, and,
- How much you stand to win if you bet on that event.
For example, if the Boston Celtics are heavily favored to win, the odds will reflect both their high probability of winning and the lower payout you’ll receive for betting on them. On the flip side, betting on an underdog (a team less likely to win) carries greater risk but offers a higher payout if they pull off an upset.
Learning how to “read” these odds will give you a clearer picture of where to place your bets. And trust me, once you’ve got it down, it’s not as complicated as it seems.
Types of Odds
Different sportsbooks display odds in varying formats depending on their location or audience preference. Here are the three most common types of odds and how to read them:
1. Moneyline Odds (American Odds)
Moneyline odds, popular in the U.S., are expressed as either positive (+) or negative (-) numbers.
- Positive odds (e.g., +200) show how much profit you’d make on a $100 bet. A +200 means you’d win $200 for every $100 wagered, plus your original $100 back.
- Negative odds (e.g., -150) show how much you’d need to stake to win $100 profit. A -150 means you’d need to bet $150 to win $100 plus your initial $150 back.
Example:
If FanDuel Sportsbook offers +300 odds on Pelicans (underdog) and -150 for Boston (favorite):
- Bet $100 on the underdog -> win $300 profit if the Pelicans win,
- Bet $150 on the favorite -> win $100 profit if Boston wins.
2. Decimal Odds
Decimal odds are commonly used in Europe and Australia. These are straightforward because they directly represent your total payout (not just the profit) for every $1 wagered.
Example: Odds of 3.50 mean that for every dollar you bet, you get $3.50 back (your $1 stake + $2.50 profit).
Decimal odds make it super easy to calculate payouts. All you need to do is multiply your wager by the odds.
Formula:
Potential Payout = Wager x Odds
3. Fractional Odds
Fractional odds (most common in the UK and horse racing) are written as fractions like 5/1 or 10/3.
- The first number (numerator) is the profit you’ll earn for every unit staked (denominator),
- Odds of 5/1 mean that for every $1 wagered, you’ll make a $5 profit, plus your original $1 back ($6 total).
Example: If you bet $10 on 5/1 odds, you’ll win $50 profit + your $10 stake = $60 total payout.
How to Read and Interpret Odds
Once you know the basics, reading odds becomes a matter of understanding probability. Sportsbook odds also provide implied probability, which is the likelihood an event will happen.
Here’s the formula for converting odds into implied probability for Moneyline and Decimal odds:
For Decimal Odds:
Implied Probability (%) = (1 / Decimal Odds) x 100
For example, decimal odds of 2.50 mean:
(1 / 2.50) x 100 = 40%
For Moneyline Odds:
- For positive odds:
Implied Probability = 100 / (Odds + 100) x 100
- For negative odds:
Implied Probability = |Odds| / (|Odds| + 100) x 100
Example:
For +150 odds, (100 / (150 + 100)) x 100 = 40% chance.
For -150 odds, (150 / (150 + 100)) x 100 = 60% chance.
Interpreting odds helps you understand how much confidence the sportsbook has in a particular outcome. Always remember, though, that these are estimates, not guarantees.
Calculating Potential Payouts
To know exactly what you might win, follow these formulas based on the odds format:
- Moneyline (American Odds):
Potential Payout = Wager + (Wager x Odds)
(For negative values, flip the base.)
- Decimal Odds:
Payout = Wager x Odds
- Fractional Odds:
Payout = (Wager x Numerator/Denominator) + Original Wager
Example:
Betting $50 on odds of +200 will earn you $150 profit ($50 x 200%) plus your $50 = $250 total win.
Factors Influencing Odds
Sportsbooks don’t just set odds randomly. Several factors come into play:
- Team Stats: Recent performance, injuries, and historical matchups all shape the odds,
- Bettor Behavior: Sportsbooks may adjust odds if many bettors place heavy wagers on a specific outcome,
- Game Context: A playoff game might have tighter odds than a regular season game,
- External Factors: Weather, player morale, or even travel schedules can impact the predicted outcome.

- Arbitrage Betting: Betting on all possible outcomes across different sportsbooks to guarantee a profit regardless of the result,
