Price per Head: Calculating Parlays

Parlays are a common bet at price per head sportsbook, especially with baseball. Customers may wonder how a parlay is calculated with money lines other than the standard 10 cents for live betting.

If the price per head money line is minus (the favourite), take 100 and divide by the money line and add 1. if the money line is a plus (underdog) take the line and divide by 100, add 1. Multiply all lines, multiply the wager amount, then subtract the wager amount.
