How to read Super Bowl 55 Odds
The Kansas City Chiefs wil meet the Tampa Bay Buccaneers in Super Bowl 55 from Raymond James Stadium in Tampa, Florida on Feb. 7, 2021.
The Chiefs opened as -3.5 betting favorites while the Buccaneers are 3.5 underdogs.
After early wagers came in, most operators are holding Kansas City -3 (-120).
If you were to wager on Kansas City -3, you would have to lay 5/6 odds (Bet $120 to win $100) instead of your normal 10/11 juice (Bet $110 to win $100).
The return on Tampa Bay would be even-money (1/1) and a $100 wager would return $100.
The total or over-under on Super Bowl 55 is hovering between 56 and 57 points.
How to read NFL Las Vegas Odds
The point-spread was developed to provide a balance for both teams involved in a contest to entice bettors to potentially back the weaker team and receive points. The two squads in a game are listed with a title, either a favorite or an underdog. The favorite is usually the perceived better team in the game, as backing them means giving up several points.
The favorite is always listed with a minus (-) sign before the point-spread while the underdog is labeled with a plus (+) label.
Ex. Favorite -10, Underdog +10
On the VegasInsider.com odds page, there is another number associated with the favorite and its listed as -10. This number is simply defined as “vig” or what many in the sports betting industry call vigorish. Another common term is called “juice” and it’s technically the price the bettor has to pay on a straight wager.
Ex. Bet $110 to win $100 (10% juice)
Ex. Bet $100 to win $90.91 (10% juice)
It's not uncommon to see other values posted other than -10. Examples seen on the NFL Vegas Odds pages could include -08, -12, -15 and -20. The -10 price is the most common value in the industry while many books offer reduced 'juice odds' and that would fall into the -08 category.
The lower-juice sportsbooks are normally found outside of the state Nevada. If you are in a state where sports betting is legal, please check out our online sportsbook directory to find the best and most secure places to make NFL bets.
Another number that’s posted on the NFL Las Vegas is the total or ‘over/under’ for the specific matchup. If the favorite is designated as the home team, then the total will be listed above and vice versa if the visitors are favorites.
All of the above numbers are listed next to the teams, and before each matchup is a Rotation number. The NFL Las Vegas Odds are listed in order of rotation and those numbers are generated and produced by the sportsbooks. Above each matchup and rotation is the Time of the game, which is subject to change. All game times are Eastern Standard Time.
NFL Open Line
One of the best features on the NFL Vegas Odds is the Open Line. This numbers consists of the first betting line received from one of our Las Vegas or Global Sportsbooks. The opening line varies depending on the sportsbook but it provides a clear-cut rating that the oddsmakers use. If you’re betting on the NFL or any other sport, it’s a great idea to view the open line first.
VI Consensus NFL Line
The VegasInsider.com Consensus NFL Line is just as important as the Open Line and also a key resource on odds platform. The Consensus column could be called a “Median Line” since it shows the most consistent number provided by the sportsbooks on VegasInsider.com. The consensus line will be the same as the open line but once the wagers start coming in, this number is often different than the openers.
Betting Nfl Tips
How do I bet on the Super Bowl?
We know that you can bet on the Super Bowl and all of NFL Futures or bet on the NFL Draft at any time of the year, but what’s the process? The future wager or the “Odds to Win” bet on the Super Bowl is correctly selecting a team to win an event that takes place at a later time. A bettor will have his wagered money tied up until there is an outcome and bettors will receive fixed odds when they place the wager. In the case of the Super Bowl, you’re not a winner or loser until you see zeros on the clock in the final game.
Nfl Football Point Spreads Vegas
Most sportsbooks offer different ways to read to Super Bowl Odds. In the fractional NFL Futures Odds format below, you simply take the odds and multiply by the amount wagered.
Ex. Green Bay (8/1) to win the Super Bowl
The Packers are listed as an 8/1 betting choice to win the Super Bowl. If you wager $100 on Green Bay to win the NFC and they capture the championship, then you would win $800 (8 ÷ 1 x 100). Your online betting account would then credit your account $900, which includes your win and stake ($100).
The American Format would see Green Bay listed at +800 and for the Decimal Format, the Packers would be 9.00.
If you are in a state where online betting is legal, we encourage you to check out our sportsbook directory to find the most trustworthy and reputable sites and mobile apps to place your Super Bowl bets.
Introduction
This page assumes the reader already has a good grasp of sports betting terminology. If this is not the case, I recommend reading my general page on sports betting first.
Unless otherwise stated, the source of this data is every NFL game played from the 2006 season through and including week 1 of the 2018 season. This is a total of 3,220 games. The data is available for free at Australia Sports Betting.
Point Spread Bets
I admit 'point spread bet' is not a common term in sports betting, but I'm trying to change that. What I call a point spread bet is a basic bet against the point spread. Many people call this a 'straight bet' but this term can also be used, and is printed on tickets for, money liney bets, total bets, and any other bet involving just one game. So I invite the rest of the world to adopt this term.
The following table shows the probability of winning, losing, and pushing according by various breakdowns.
Point Spread Bets in the NFL

- Losses: Number of losses against point spread
- Pushes: Number of pushes against point spread
- Win Rate: Ratio of wins to bets resolved
- Std. Dev.: One standard deviation in the mean of the win rate, assuming every bet had a theoretical chance of winning of 50%.
- N.S.D: Number of standard deviations that the actual results differ from an expected win rate of 50%.
- Return: Ratio of money won (lost = negative) to money bet, assuming laying 11 to win 10.
Over/Under Bets
Betting Nfl Lines
The following table shows the results of under and over bets. It shows both had nearly a 50% chance of winning. In face, over 3,220 games the over won just two more times than the under. I thought under bets would have performed better, but I've been wrong before.
Under and Over Bets in the NFL
| Bet | Wins | Losses | Pushes | Win Rate | Std. Dev. | N.S.D. | Return |
|---|---|---|---|---|---|---|---|
| Over | 1,586 | 1,576 | 58 | 50.16% | 1.26% | 0.13 | -4.17% |
| Under | 1,576 | 1,586 | 58 | 49.84% | 1.26% | -0.13 | -4.76% |
Money Lines
The following brief table shows the result of money line bets.
Money Line Bets in the NFL
The next table shows the actual and estimated probability of winning for underdogs of 1 to 14.5 points. Obviously, the probability of the favorite winning would be 100% less the probability of the underdog winning. The estimated probability of winning uses logistic regression to smooth out the ups and downs.
Probability of Winning by Point Spread in the NFL

|---|---|---|---|---|---|
| 1 | 139 | 69 | 49.6% | 46.4% | 115 |

If you want to estimate the probability of winning of an underdog of more than 14.5 points, the formula is e^(-0.14324*s)/(1+e^(-0.14324*s)), where s is the point spread. To convert any probability under 50% to a fair money line, the formula is 100*(1-p)/p, where p is the probability of winning. To convert any probability over 50% to a fair money line, the formula is -100*p/(1-p).
Parlays
Here is my quick advice on parlays:
- If you bet off the board, either do a pick-3 or mix in one leg that isn't at the standard -110 odds, to get off the lousy parlay odds table, and force a fair calculation.
- On parlay cards, try to capture as many points as you can compared to the 'off the board' point spread.
I have much more information about parlays in my page on Parlay Bets in the NFL.
Teasers
Here is my quick advice on teasers:
- If you bet off the board, the best odds are at Jerry's Nugget.
- Try to cross the 3- and 7-point margin of victories with the extra points.
- Teaser cards are a sucker bet.
- If you must bet a teaser card, I recommend the the Ties Win Teaser Card at any Caesars sports book.
- On teaser cards, try to capture as many points as you can compared to the 'off the board' point spread.
I have lots more information about teasers in my page on Teaser Bets in the NFL.
Buying Half a Point off the Spread
Sometimes a sports book will let you buy a half point off the spread for total. For example, moving a point spread from +10 to +10.5. The price for this is laying an extra cents, in most cases laying 120 instead of 110. However, rarely will a sports book let the player buy onto point spreads of 3 or 7, for example moving from +2.5 to +3, because 3 and 7 are frequent margin of victories (MOV) in the NFL. To be specific, the margin of victory is three 14.5% of the time, and seven 9.2%, as the following table shows.
Margin of Victory in the NFL
| MOV | Probability |
|---|---|
| 0 | 0.2% |
| 1 | 3.7% |
| 2 | 3.8% |
| 3 | 14.5% |
| 4 | 5.2% |
| 5 | 3.4% |
| 6 | 6.2% |
| 7 | 9.2% |
| 8 | 3.6% |
| 9 | 1.7% |
| 10 | 5.6% |
| 11 | 2.5% |
| 12 | 1.5% |
| 13 | 2.9% |
| 14 | 4.8% |
| 15 | 1.5% |
| 16 | 2.1% |
| 17 | 3.1% |
| 18 | 2.3% |
| 19 | 1.1% |
| 20 | 2.4% |
| 21 | 3.2% |
| 22+ | 15.7% |
| Total | 100.0% |
The following table shows the fair price to pay for most spreads and totals. For example, moving the spread from +2.5 to +3, +3 to +3.5, -3.5 to -3, or -3 to -2.5, would be buying the 3. In these cases if the favorite won by 3, or the underdog lost by 3, then it would turn a push into a win, or a loss into a push. The table shows the fair price to pay for extra half point, to equal the expected loss of 4.54% laying 11 to win 10. The bottom line is you should definitely buy the half point off of three, if you can, and it is marginally good off of seven. Anything else and it is a bad value.
Buying a Half Point Off the Spread
Buying Half a Point off the Total
The overall fair number of basis points to pay for a half point off the total is 8.12. In other words, you should be indifferent to laying 11 to win 10 and laying 118.12 to win 10 with an extra half point. The following table shows my suggested fair price to pay to capture totals from 30 to 60. By 'capture' I mean turn a push into a win or a loss into a push. If you have to lay 10 basis points for the half point, my table shows that it is never a good value, although sometimes it is close. An explanation of the column headings follows the table.

Key to column headings:
- Total Points = Total point scored in game
- Num. in Sample = Number of times this total appeared in a sample of 3,220 games.
- Fair Price = My fair number of basis points to pay to capture this number (after a lot of math)
Betting Nfl Games
My page on alternate point spreads shows what it is worth to buy or sell up to seven points off the spread. That page has not been updated with the latest data yet.
Example
Online Betting Nfl
Assume the over/under on a game is exactly 43 points. My table shows the fair number of basis points to pay to capture the 43 is 9.45. This means you should be indifferent to laying 110 on the under 43 or over 43 to laying 119.45 on the under 43.5 or over 42.5.
