How to Bet Moneylines
Learn what moneyline bets are, how they work, and strategies for finding value on favorites and underdogs in NFL, NBA, MLB, and more.
The moneyline is the foundation of sports betting. It's the simplest bet type — you're simply picking who will win. But beneath that simplicity lies a world of strategy, value identification, and bankroll management that separates winning bettors from losing ones. Whether you're betting on tonight's NBA game or Sunday's NFL slate, understanding moneyline odds is the first skill every sports bettor needs to master.
What Is a Moneyline Bet?
A moneyline bet is a straight-up wager on which team or player will win a game or event. Unlike point spread betting, there's no handicap involved — the team you pick simply needs to win for your bet to cash. Moneyline bets are available across every sport offered by legal sportsbooks including football, basketball, baseball, hockey, soccer, tennis, golf, and combat sports. In sports like baseball and hockey where scoring margins are typically small, the moneyline is the most popular bet type. In football and basketball, moneylines complement spread betting as an alternative way to back a team you believe will win.
Example
If the Kansas City Chiefs are playing the Las Vegas Raiders and the Chiefs moneyline is -200, a $200 bet on the Chiefs wins $100 if they win the game by any score. If the Raiders moneyline is +170, a $100 bet on the Raiders wins $170 if they pull the upset.
How to Read Moneyline Odds
Moneyline odds in American format use plus (+) and minus (-) signs. Negative odds indicate the favorite — the number shows how much you must bet to win $100. Positive odds indicate the underdog — the number shows how much you win on a $100 bet. The magnitude of the number reflects how heavily favored or unfavored a team is. A -500 favorite is expected to win far more often than a -120 favorite. A +400 underdog is a bigger long shot than a +110 underdog. Understanding implied probability is crucial: divide 100 by (the moneyline number + 100) for underdogs, or divide the moneyline number by (the moneyline number + 100) for favorites. A -150 favorite has an implied win probability of 60%, while a +150 underdog implies a 40% win chance.
Pro Tip
Convert moneyline odds to implied probability before placing any bet. If you believe a team wins more often than the implied probability suggests, you've found a value bet.
Moneyline Odds Across Sports
Moneyline pricing varies significantly by sport based on typical scoring margins and upset frequency. In MLB, moneylines typically range from -120 to -200 for favorites because any team can win on any given day — pitching matchups create enormous variance. NFL moneylines can stretch from -120 to -1000+ for lopsided matchups, though most games fall in the -150 to -300 range. NBA favorites are often -200 to -500 due to the sport's lower variance and the fact that better teams win more consistently. NHL moneylines tend to be tighter, usually in the -130 to -220 range, reflecting hockey's inherent unpredictability. Understanding these ranges helps you gauge whether a moneyline price is reasonable or represents value in each sport.
Finding Value on Favorites
Betting favorites on the moneyline can be profitable if you're selective about price. The key is avoiding massive favorites where the risk-reward ratio is poor. A -350 favorite needs to win 77.8% of the time just to break even. In sports like the NFL where even the best teams win only 70-75% of their games, that's a losing proposition long-term. Instead, focus on small-to-moderate favorites (-120 to -200) where the implied probability leaves room for value. Look for situations where public perception undervalues a team — perhaps a strong team coming off a loss, or a dominant squad in an overlooked matchup.
Pro Tip
Track your closing line value (CLV). If you consistently bet favorites and the line moves further in your team's favor before game time, you're likely identifying value correctly.
Finding Value on Underdogs
Underdog moneylines are where many sharp bettors focus their attention. The key insight is that you don't need to win most of your underdog bets to be profitable — you just need to win often enough relative to the odds. A +200 underdog only needs to win 33.3% of the time to break even. A +300 underdog needs to win just 25% of the time. In the NFL, where any team can beat any other team on a given Sunday, underdogs cover at a surprisingly high rate. Dogs of +200 or larger in the NFL win roughly 25-30% of the time, which is often enough to be profitable at those odds. Look for underdogs with strong defensive metrics, teams playing at home, or situations where public money has inflated the favorite's price.
Example
If you bet $100 on underdogs at +200 ten times and win 4 of those bets, you'd profit $200 on wins ($800 total returned on $400 bet) while losing $600 on six losses. Net profit: $200 on $1,000 wagered — a 20% ROI.
Moneyline Parlays: Pros and Cons
Parlaying moneyline favorites is one of the most popular bet types among recreational bettors, but it's a strategy that requires caution. Combining three -200 favorites into a parlay yields about +175 odds, which seems attractive. However, the probability of all three winning is approximately 29.6% (0.667 × 0.667 × 0.667), and the parlay typically pays slightly less than true odds due to the sportsbook's built-in margin. Moneyline parlays can be profitable when used selectively — particularly when you've identified multiple strong favorites in a low-variance sport. But avoid the trap of parlaying heavy favorites just because they 'should' win. One upset wipes out the entire parlay, and upsets happen more often than most bettors expect.
Warning
Never parlay more than 3-4 moneyline favorites. The probability of hitting a 5+ leg favorite parlay is extremely low, and the payout rarely compensates for the risk.
Moneyline Betting Mistakes to Avoid
The most common moneyline mistake is betting massive favorites without calculating the implied probability. Laying -400 on a team means you need them to win 80% of the time to break even — most teams simply don't win at that rate consistently. Another common mistake is ignoring line movement. If a moneyline moves from -150 to -180, ask why before betting. Sharp money, injury news, or weather changes may have triggered the move. Finally, don't bet moneylines reactively based on last week's results. A team that lost big may actually be a better bet the following week if the market overreacts to the loss.
