So if the underdog is paying +180, a winning $100 bet will put $280 into your wallet ($180 profit + $100 original wager). With the underdog the positive number represents how much profit you will win on a $100 bet.A simple way to understand the value it represents is to say, “If I bet exactly that amount, and the team wins, I will make $100 of profit.” So in this example, a $140 wager returns $240 ($100 profit + $140 original wager) to your pockets. With the favorite, you’ll see a negative number, something like -140 for example.This can be confusing at first but stick with us, we promise it will get easier. The best way to understand how these numbers relate to your potential wager is by basing everything on $100. You’ll know you’re looking at a money line when you see a plus (+) sign next to the underdog and a minus (-) next to the favorite. Unlike the points spread and totals bets, the money line is in no way concerned with how many points are scored or the margin of victory. To put it simply, a money line wager is betting on who will win the game.
