It’s uncommon for bettors to use fractional odds for sports betting, other than in racebooks, where it’s frequently used, because making conversions in your head is tough. An example of this would be if a bettor puts $100 on the Mavs to win the NBA Finals. If the odds are -140 for the Mavs against the Suns, that means Dallas is the slight favorite. A bettor would need to stake $140 to win $100 on the packers. If you look at underdog odds, the ‘+’ sign represents the profit you can make for every $100 wagered. Just to say, if you’re unfamiliar with any of the betting language being used here, take a look at our complete glossary of betting terms.

Calculating parlay odds can be difficult because different sportsbooks employ different formulas, and the types of bets can vary so greatly.
