What does moneyline mean in betting?
The moneyline is the most basic bet in sports gambling: you pick who wins the game. No points, no margins, no handicaps — just a winner and a loser. The number attached to each team (like -150 or +200) is the price of that pick, and learning to read those numbers is the first skill every bettor needs.
How to read a moneyline
American odds always centre on $100. Minus numbers tell you how much you have to risk to win $100; plus numbers tell you how much you win on a $100 bet. A typical moneyline board looks like this:
Yankees -180 favourite: bet $180 to win $100 Red Sox +150 underdog: bet $100 to win $150
Two things follow from the sign. First, the favourite is always the minus side — the market charges you a premium for the team more likely to win. Second, the further the number sits from even, the more one-sided the market thinks the game is: -400 is a landslide favourite, -110 is nearly a coin flip, and +300 is a live underdog.
What your bet actually pays
You do not have to bet $100 — the odds scale to any stake. The quick mental math:
Minus moneyline: divide by the number
At -200, every $2 risked wins $1. A $50 bet wins $25; a $100 bet wins $50. Your stake comes back too, so a winning $100 bet at -200 returns $150 total.
Plus moneyline: divide by 100
At +150, every $1 risked wins $1.50. A $20 bet wins $30; a $100 bet wins $150. A winning $100 bet returns $250 total.
Near even: about half your stake
Lines like -105 to -115 are effectively coin flips with a fee. A $100 bet at -110 wins about $91 — that small haircut is the vig, the sportsbook's commission.
If you want to know whether a price is fair rather than just what it pays, that is implied probability — we do the full conversion in our expected value guide. A -200 favourite is being priced as roughly a 67% winner; if you think they win more often than that, the price offers value.
Moneyline vs. the spread
The moneyline answers who wins; the spread answers by how much. Same game, two different prices, and the choice between them is a real decision:
Take the moneyline when you expect an outright win
A modest favourite at -140 pays better per dollar than laying -3 on the spread — if you are confident they win the game at all.
Take the spread when the favourite is a monster
Laying -400 on the moneyline to win $25 is poor risk-reward; the spread prices the same team near even and asks only that they win comfortably.
Underdog moneylines swing hard
A +180 dog pays nearly double your stake, but wins outright far less often than the same dog +4.5 covers. Underdog moneyline bettors are paid for swallowing a lot of losses.
We compare the two side by side with a worked example in the point spread guide.
Three moneyline habits to avoid
- 1
Paying heavyweight prices every night
Betting -250 favourites feels safe, but one upset wipes out six wins. At -250 you need to be right about 71% of the time just to break even — a bar most 'safe' favourites do not clear.
- 2
Chasing longshots for the payout
+400 dogs are +400 for a reason. An occasional splash is fine; a diet of big-plus tickets is how bankrolls disappear. Size these bets smaller, which our bankroll guide covers.
- 3
Reading the price as a prediction
The moneyline is a market price, not a forecast. Books shade lines toward public money, so the favourite is often slightly overpriced. Compare the number to your own win-probability estimate before betting it.
No moneyline strategy guarantees a winning ticket. The price tells you what the market believes; your job is deciding whether you know something the price does not.
