Parlay Calculator Pro Football Network's free parlay calculator allows you to build your parlay for as many different legs as you want and do the math for you. Luckily, sportsbooks do this complicated math for us, but you can read a full explanation here. Pro Football Network has you covered with this easy-to-use Betting Calculator. * Confused where +243 came from? To calculate a parlay, the odds must first be changed into decimal odds, multiplied together and then reconverted back to American odds.

You can also parlay bets across sports (a Packers and NWSL’s Portland Thorns bet, perhaps?) but most sportsbooks will cap a parlay at 10 total bets. Remember: the less likely an outcome, the more money you could make. The reason the payout is bigger is because the chances of both of those bets winning is much smaller.You can bet on those individually or you can parlay them together with a combined odds of +243*. Let’s say you want to bet on the Green Bay Packers to win (-110) and the total score of the game to be more than 50 points (-125).Those taking Seattle need to only wager 100 to win 150 (+150). A bettor has to risk 175 to win 100 (-175). Reading these betting odds, Green Bay Packers is considered a slight favorite to win. A parlay (no, not that parley) combines two or more bets to greatly increase your possible payout but…it greatly decreases the chance of actually winning. Here’s an example of American betting odds on the winner of a game: Green Bay Packers -175. Again, there are no point spreads involved, you are simply picking the winner of the game.Think of a parlay like a layered bet. If you are looking to play a +175 underdog on the moneyline, you would lay $100 to profit $175 and collect $275. If you are betting on the underdog, the number that you see is the amount that you would win off a $100 bet. If you are betting on a -200 favorite, you need to lay $200 to profit $100, and you would collect $300. If you are looking to play the favorite on the moneyline, the number that you see is the amount that you need to lay in order to win $100. Conversely, betting on an underdog on the moneyline will earn a larger profit.

Since there is no point spread involved, betting on the favorite requires you to bet more to win a desired amount on the moneyline. Betting on the moneyline means you're just picking the winner of the game, with no point spread or other factors involved. Some casual bettors don't want to worry about the point spread or the over-under, they just want to pick a winner.
