Betting Odds Explained
American Odds – American Odds are the default odds format at most US friendly betting sites as well as Nevada sports books. Here odds are expressed as either a negative or a positive number. When positive the odds represent how much a player will profit on a successful $100.00 wager. So for example if the odds are +180 a successful $100 bet will return $280 (the $100 stake + $180.00 win). When the odds are negative they represent how much a bettor must stake to win $100. Therefore $150 staked at -150 returns $250.00 (the $150 stake + $100 win).
Decimal Odds – Decimal Odds, also referred to as European Odds, are used in most European countries and are the default option of many Asian bookies as well. This is the easiest odds format to understand as the odds represent how much a 1 unit wager returns. For example a €1 wager at odds 1.91 returns €1.91. This return includes both your stake plus profit; to calculate how much your return will be simply multiple your stake by the given odds.
Fractional Odds – Fractional Odds are used in the UK and Ireland. Here the first number is the amount to be won, and the second number is the stake. So for examples 4/1 is stake 1 to win 4, and 10/11 is stake 11 to win 10. To calculate how much a winning bet will profit, convert the fraction to a decimal and multiply it by the stake. For example 3/2=1.5, so, if wagering at 3/2 a successful bet will return 1.5 times your stake in winnings and will also return your stake.
Implied Probability – Implied Probability is how often a bet must win to average break even. This is calculated as risk/return, so for example +200 in American format (3.00 European) is risk $100 to win $200 so a winning wager returns $300 ($100 stake + $200 win). Therefore the implied probability of +200 is $100/$300= 0.3333, which is 33.33%. For this reason you should only wager at +200 if you think the probability of winning is greater than 33.33%.

Biggest slot win in vegas. For those of you who aren't familiar with betting the money line in the NFL it's simple. You are essentially wagering on who you think will win the game. There's no point spread involved. There is just an increase in the juice based on the percentage chances of a team winning outright.
For example, the money line on a 3-point home favorite in the NFL would have odds like -164 to win the game outright. This means you would need to wager $164 to win $100 on that team. On the flip side, you could bet a 3-point underdog at +135 to win outright, meaning you would wager $100 to win $135.
What I'm interested in when looking at the weekly odds is whether certain moneyline bets are profitable. Each chart below shows two money lines. The first is the 'expected moneyline'. We took the win percentages for all NFL games since 1980 at each line and converted them into a money line. The 'actual moneyline' is what a typical sportsbook would set for each spread.
Why is this something you need to know? Home favorites of -3.5 win the game 63.61% of the time. If you look at the chart we've converted that to a money line of -175 (expected moneyline). The problem is a book would make you pay around -206 (actual moneyline) for a -3.5-point favorite. Thus, it's obviously not a good bet.
The same goes for underdogs. Say you see a home underdog of +2 and decide you might as well take the money line. The actual line you would get would be something close to +105. The expected moneyline for 2-point home underdogs is +119. If the actual moneyline comes in lower than the expected moneyline then history says you are not getting value on your wager.
As you'll see, it's pretty rare to find instances where taking the money line is a valuable play. There are obviously significant differences between certain situations. So, I've broken the data into four groups: home favorites, road favorites, home underdogs and road underdogs.
*Please note that some higher lines did not have enough games to qualify as significant data. For those games we used estimated win percentages to better represent those numbers.

As with everything in gambling, the house almost always has the edge. This certainly doesn't mean you have to avoid betting moneylines in the NFL, but check these charts to make sure you are maximizing the value of those wagers.

You'll also notice that it's better to do a two-team 6 point teaser on favorites of 6 or 7 points instead of doing a money line parlay. That's just one of the reasons we love NFL teaser wagers so much.
