A parlay takes multiple wagers and combines them into a single ticket. For a parlay to pay off, all bets on mixparlay.io the ticket must win. If even one pick on a parlay loses, the entire ticket is a loser.
Parlays present a higher risk for bettors, but can also pay off at dramatically higher odds versus single bets. The Gaming Today Parlay Calculator functions as a tool that allows you to see the parlay odds and implied win probability for any combination of bets.
What Is A Parlay Bet?
Legal sportsbooks allow bettors to put together just about any combination of available bets and play them as a parlay. Any ticket that combines two or more bets into a single ticket qualifies as a parlay wager.
The odds on a parlay bet are calculated as moneyline odds, and most US-facing legal sports use the American odds notation to display moneyline odds. American odds are denoted by a “+” or “-“ in front of the odds number. For example, lines like -110 and +150 use the American Odds notation.
Calculating Payouts From Positive Moneyline Odds
To calculate “+” American odds, take the odds number and divide by 100, then multiply that by the size of the bet.
A $50 bet at +150 odds, for instance, is calculated as 150/100 (which yields 1.5), multiplied by $50 (1.5*$50=$75). A winning $50 bet at +150 odds would return $125 total to the bettor ($75 profit plus the original $50 bet.)
Calculating Payouts From Negative Moneyline Odds
To calculate “-“ odds, divide 100 by the odds number, then multiply by the amount of the wager.
A $50 bet at -110 odds would be calculated as 100/110 (without the “-“ for the 110 odds), which yields 0.909. You then multiply that by the size of the bet (0.909*$50=$45.45). A $50 winning bet at -110 odds would return $95.95 to the bettor ($45.45 profit plus the original $50 bet).
Decimal Odds
American odds aren’t the only notation sportsbooks use to display moneyline odds. Decimal odds represent another common way to display moneyline odds. Odds notations like 1.20 and 10.00 are moneyline bets represented with decimal odds.
To convert “+” American odds into decimal odds, take the odds number and divide by 100, then add 1. Converting +150 to decimal odds is executed as (150/100)+1. That reduces to 1.5+1, which equals 2.5. So 2.5 decimal odds are equivalent to +150 American odds.
Converting “-“ odds to decimal odds requires dividing 100 by the odds and subtracting that quotient from 1. The -110 are converted as 1-(100/-110), which reduces to 1-(-0.909) and solves as 1.909. So -110 American odds convert to 1.909 decimal odds.
To calculate the return on a bet using decimal odds, multiply the wager by the odds. For example, a $50 bet at 1.909 decimal odds returns $95.45 to the bettor. To calculate profit, subtract the amount of the wager from this product ($95.45-$50=$45.45).
Favorites Versus Underdogs
The favorite in a game is the team with the higher implied probability of winning. Favorites are denoted by “-“ odds when using American odds. Favorites win more often overall, but pay out less on a win compared to underdogs.
Underdogs are the team with the lower implied probability of winning and are denoted with “+” odds. When making a parlay bet, combining multiple underdogs can produce potentially huge payouts, but the implied winning probability of such a ticket is low.
Implied Probability
The Gaming Today Parlay Calculator allows you to take any number of moneyline bets, input them into the calculator, and see both the payout odds and implied probability of winning. Implied probability can be derived from any moneyline number.
