What does -150 mean as a percentage?

Convert American odds to decimal, fractional and implied probability, or turn a win chance into fair odds.

How it works

• Decimal odds are the total return per $1, stake included: +150 is 2.50 and -200 is 1.50.
• Implied probability = 1 / decimal odds. -110 implies 52.4%.
• Positive American odds are the profit on $100; negative odds are the stake needed to win $100.

Questions

What does -110 mean?

Bet $110 to win $100. Its implied probability is 52.4%, so you need to win more than 52.4% of these bets to profit.

Is implied probability the real chance?

No. A sportsbook price includes its margin, so both sides add up to more than 100%. Use the no-vig calculator to remove it.
