Moneyline odds explained

A moneyline is a bet on who wins, with no point spread. The odds set the payout. A minus number is what you stake to win 100. A plus number is what a 100 stake wins.

Worked example

To start, the box below is filled in with LAL -200 / BOS +170. This starting line has both sides of one game, so its card also shows the bookmaker's margin. The box is editable: type any line, or tap one under the card, and the explanation updates.

LAL −200 / BOS +170: the favorite is LAL (−200) and the underdog is BOS (+170).

What it means

A moneyline is a bet on who wins, with no points involved. A bet on LAL risks 200 to win 100. A 100 stake on BOS wins 170.

On a 2-way moneyline, what happens on a tie or draw depends on the sport and the sportsbook's rules. In boxing, a two-way market (just the two fighters) refunds the stake on a draw. A three-way market that includes the draw loses both fighter bets.

Margin (overround) = the implied probabilities added together, minus 100%. Fair probabilities remove the margin by dividing each one by that total.

Watch out for

A minus price doesn't mean you lose money. −200 means you stake 200 to win 100, and the 200 comes back too if the bet wins.

Common lines to try

Reading minus and plus

American odds are built around 100.

  • Minus (−200): how much you stake to win 100. Stake 200, win 100, get 300 back in total.
  • Plus (+170): how much a 100 stake wins. Stake 100, win 170, get 270 back in total.
  • +100, also called evens, is the point where the two meet. Stake 100, win 100.

A minus price marks the favorite and a plus price marks the underdog, the same as on a point spread. On a moneyline there is no head start in points: the team only has to win.

Odds Profit per 100 staked Total return per 100 Implied probability

The odds converter shows these as decimal and fractional odds too.

Implied probability

Implied probability turns a price into a percentage.

  • Minus odds: stake ÷ (stake + 100). For −200: 200 ÷ 300 = 66.67%.
  • Plus odds: 100 ÷ (odds + 100). For +170: 100 ÷ 270 = 37.04%.

It describes the price, not the game. This site doesn’t say how likely a team is to win.

Why both sides add up to more than 100%

For LAL -200 / BOS +170: 66.67% + 37.04% = 103.70%.

The 3.70% above 100% is the bookmaker’s margin, also called the overround. Divide each side’s implied probability by 103.70% and you get the fair probabilities, which add up to exactly 100%: 64.29% and 35.71%.

Some sites quote hold instead, which comes out a little smaller. The glossary explains the difference.

When the game ends level

What happens on a tie depends on the sport and the market, so check the house rules.

  • Soccer usually uses a 3-way market (home, draw, away). A draw loses a bet on either team.
  • Boxing depends on the market. In a two-way market (just the two fighters), a draw refunds the stake. In a three-way market that includes the draw as an outcome, a draw loses a bet on either fighter.

Common misreadings

A minus price means you lose money.
-200 means you stake 200 to win 100. If the bet wins, you get the 200 stake back as well, so 300 in total.
+170 means a 170% chance.
+170 is a payout: a 100 stake wins 170. As a probability it works out to 37.04%.
Implied probability is the real chance of winning.
It's what the price implies, and it includes the bookmaker's margin. Removing the margin gives fair probabilities, but neither number is a prediction.
