At its core, a moneyline wager is the simplest and most direct wager in sports gambling. When you place a moneyline bet, you are simply picking which team, athlete, or competitor will win the game or event outright. Unlike point spreads, which require a team to win or lose by a specific margin, or totals (over/unders), which focus on combined scoring, moneyline wagers care about only one outcome: the final result.
While the concept of picking a winner is straightforward, reading and interpreting moneyline odds requires understanding how oddsmakers price risk, calculate potential returns, and adjust lines leading up to game time.
Navigating American Odds Formats: Minus (-) vs. Plus (+)
In North American sportsbooks, moneyline odds are expressed using the American odds format, which uses three-digit numbers centered around a $100 baseline. The figures indicate two distinct roles: the favorite and the underdog.
Reading the Favorite (-)
The favorite is always designated by a minus sign (–). The number following the minus sign indicates the exact dollar amount you must wager in order to win $100 in profit.
- Example: If the Kansas City Chiefs are listed at -150 against the Las Vegas Raiders, you must place a $150 bet to generate a $100 profit. A winning ticket returns your original $150 stake plus the $100 profit, totaling $250.
The larger the number following the minus sign, the heavier the favorite, indicating that bookmakers view that outcome as highly probable.
Reading the Underdog (+)
The underdog is designated by a plus sign (+). The number following the plus sign indicates the profit you will earn on a successful $100 wager.
- Example: If the Las Vegas Raiders are listed at +130, a $100 wager yields $130 in pure profit. A winning ticket returns your $100 stake along with $130 in profit, totaling $230.
Underdog odds offer higher relative payouts because the implied probability of their victory is lower.
Calculating Payouts across Different Odds Formats
While American odds are standard in the United States, oddsmakers globally utilize decimal and fractional formats. Understanding how to calculate potential returns across these systems ensures clear evaluation of risk versus reward.
| Odds Format | Example Listing | How Payout Is Calculated | Return on a $100 Bet |
| American (Favorite) | -200 | Risk amount / (Odds / 100) | $100 Stake + $50 Profit = $150 Total |
| American (Underdog) | +175 | Risk amount * (Odds / 100) | $100 Stake + $175 Profit = $275 Total |
| Decimal | 2.75 | Risk amount * Decimal Odds | $100 Stake * 2.75 = $275 Total |
| Fractional | 7/4 | (Risk amount * Numerator) / Denominator | ($100 * 7) / 4 = $175 Profit ($275 Total) |
Converting Moneyline Odds to Implied Probability
To determine whether a moneyline line offers value, bettors convert published odds into implied probability—the likelihood of a specific outcome expressed as a percentage.
The Math Behind Implied Probability
For favorites with negative odds:
$$\text{Implied Probability} = \frac{\vert{}\text{Negative Odds}\vert{}}{\vert{}\text{Negative Odds}\vert{} + 100}$$
- Example at -150: $150 / (150 + 100) = 150 / 250 = \mathbf{60.0\%}$
For underdogs with positive odds:
ImpliedProbability=100PositiveOdds+100
- Example at +130: $100 / (130 + 100) = 100 / 230 = \mathbf{43.48\%}$
Notice that combining both probabilities ($60.0\% + 43.48\% = 103.48\%$) totals more than $100\%$. The excess $3.48\%$ represents the bookmaker’s profit margin, known as the vig or juice.
Comparing Moneylines across Major Sports
The dynamic of moneyline wagering changes significantly depending on the structure and scoring volume of individual sports.
- Football & Basketball (High Scoring): Moneyline odds on heavily favored football or basketball teams are often priced steeply (e.g., -400 to -1000). Because scoring is frequent, superior talent wins more consistently, making outright upsets less common than in lower-scoring sports.
- Baseball & Hockey (Low Scoring): Because scoring events in MLB and the NHL are infrequent, variance plays a massive role. As a result, moneyline odds in baseball and hockey rarely exceed -250 or +220, making moneyline wagering the primary way people bet on these sports rather than point spreads (run lines or puck lines).
- Soccer & Combat Sports (Three-Way Markets): In soccer, standard moneylines are structured as “Three-Way Moneylines,” offering three distinct choices: Team A Win, Team B Win, or Draw. If you bet Team A and the match ends in a tie after 90 minutes, the wager loses unless you explicitly select the “Draw” option or play a “Draw No Bet” market.
Market Dynamics: Line Movement and Expected Value
Moneyline odds are not static; they shift continuously from the moment oddsmakers open a market until game time. Understanding why lines move helps bettors spot opportunities.
- Sharp Action vs. Public Volume: Bookmakers adjust lines to balance their risk exposure or in response to respected, high-volume bettors (“sharps”). If heavy capital comes in on an underdog at +150, bookmakers may lower those odds to +135 while shifting the favorite from -170 to -155.
- Key News and Conditions: Roster updates, starting pitcher announcements, injuries, and weather shifts directly influence moneyline pricing.
- Finding Positive Expected Value (+EV): Successful moneyline handicapping relies on identifying lines where your calculated win probability exceeds the oddsmaker’s implied probability. If your analysis indicates a team has a $50\%$ chance to win, but the market lists them at +120 (implied probability of $45.45\%$), a positive expected value exists.
Conclusion
Moneyline wagering offers a straightforward way to engage with sports betting by focusing purely on who wins the contest. However, long-term success requires going beyond simply picking winners. By mastering the conversion of odds into implied probability, assessing sport-specific variance, and evaluating line movements against market value, bettors can make informed decisions when reading sportsbooks’ odds boards.
Frequently Asked Questions
What happens to a moneyline bet if the game goes into overtime?
In most North American sports (NFL, NBA, NHL, MLB), two-way moneyline bets include overtime. If your selected team wins in extra time, your bet pays out. In soccer, standard three-way moneylines cover 90 minutes plus stoppage time only; overtime or penalty shootouts require specific “To Advance” or “To Lift the Trophy” markets.
What occurs if a moneyline event ends in a tie (Push)?
In a two-way moneyline market where no tie option was offered (such as an NFL game that ends in a draw after overtime), the bet is declared a “push.” The sportsbook voids the wager and returns your full original stake.
Is it better to bet the moneyline or the point spread?
It depends on the scenario and pricing. Point spreads reduce risk on underdogs (giving them extra points) and require favorites to win by a margin. If you believe an underdog can win outright, taking them on the moneyline offers a significantly higher payout than taking the points on a spread.
Can you combine moneyline wagers into a parlay?
Yes. A moneyline parlay combines two or more individual moneyline picks into a single wager. All selected teams must win outright for the parlay to pay out. The odds multiply across each leg, yielding higher potential returns along with increased risk.
What does “Draw No Bet” mean on a moneyline?
“Draw No Bet” is a modified moneyline market popular in soccer that removes the option of a tie. You bet on either Team A or Team B to win. If the match ends in a draw, the wager pushes, and your stake is refunded.
