The tool to the left can be used to calculate no-vig odds and no-vig win probabilities. For example, if the moneylines of an NFL football game are NY Giants -160 / Atlanta Falcons +140 novice bettors often make the mistake of assuming the fair odds without juice are Giants -150 / Falcons +150. This is a mistake, enter -160 and +140 into our no-vig calculator and you’ll see the actual no-vig odds are -148 / +148. If you’re thinking okay what’s 2 cents worth… try doing the same for Saints -600 / Lions +450. The novice bettor mistakes the fair odds as -525/+525 while our tool shows the actual no-vig odds are -471 / +471.
The reason this illustration is important is because a novice bettor finding -500 when all other sites have -600 will be overly excited feeling he’s most certainly found a +EV (positive expected value) bet. As shown in this illustration that’s often not the case. On -600/+450 beating the favorite line by 100 cents is still –EV (negative expected value). Meanwhile although still –EV getting +465 when all other sites had +450 would be a FAR better bet, and here he’s only found 15 cents better as opposed to the 100 cents better on the favorite.
How do Bookmakers Add Vig?
At the risk of losing the casual reader I’ll go ahead and answer this question. The bookmaker first decides on how much advantage he wants to add to a betting line. For example if he has the probabilities as 82.5% favorite / 17.5% underdog and he wants to keep around 3.75% of the wagered amount on balanced action he’ll add this to each probability. .825*1.0375=0.8559 (85.59%) and 0.175*1.0375=0.1816 (18.16%). To see what these are in American odds, head over to our odds converter and in the implied probability field enter 85.59% to see this is -594. Next enter 18.16 to see this is +450.66. The bookmaker has a large enough advantage here so with the desire to use round about numbers he’ll most likely set the odds at -600 / +450. The juice is roughly the same on each as remember 6 cents added to a -594 price is peanuts, because the fair price of -600/+450 is -471/+471 (this was mentioned two paragraphs up). In any case notice the gap between -600 and +450 is 150 cents yet the Bookmaker has just a 3.75% advantage here.
To test this out on another line set, let’s say the bookmaker has handicapped the favorite having a 55% chance of winning and wants to add the same 3.75% advantage. The math is .55×1.0375=57.06% and .45×1.0375=46.69%. Using the implied probability field of our odds converter we see this gives us moneylines of -133 and +114 here the bookmaker is likely to round again to -135 / +115. His advantage is still in the 3.75% range of the previous example, yet the gap here is 20 cents instead of 150 cents. Hopefully you’re now seeing why moneylines cannot be averaged to remove juice.
How to Remove Juice from Moneylines
To remove the juice from moneylines the first step is to convert the betting odds to implied probabilities using risk/return=implied probability. For a moneyline of -600, if a bettor risks $600 they win $100 and therefore the return is $700 ($600 stake + $100 win). So here the math is 600/700=0.8571 (85.71%). If the opponent’s moneyline is +450 and a bettor risks $100 it is to win $450 and therefore the return is $550 ($100 stake + $450 win) so the math is 100/550=0.1818 (18.18%). Now note that implied probability represent how often you need to win on average to break even, and here 85.71% + 18.18% = 103.89%. The reasons the probabilities total greater than 100% is because of the bookmaker advantage called juice or vig. To remove this we need to divide each implied probability by the overall percent market (in this case 103.89%). So 85.71/103.89=82.5% and 18.18/103.89=17.5%, you see these now total 100% so the vig is removed. We now know the no-vig win probability of -600 / +450 is 82.5% and 12.5%. You can save doing out this math by using the tool at the top of our article. Perhaps I’ll write another article in the future on converting these percentages to American odds format, but for now you can enter them into our odds converter tool under the implied probability field to solve the answer is -471/+471.
Best Use of this Knowledge
Now that you understand a bit more about moneylines, you can use this information to “handicap the market”. Although they don’t openly accept US players, it is well known Pinnacle Sports offers the highest betting limits and fastest payouts while operating on the lowest margins. For NFL football games point spreads are priced -104 instead of the usual -110, and Pinnacle accepts massive wagers on these ($30,000 and $100,000 per bet limits in some cases). A good idea is to watch their website and compare their prices on moneylines, totals and point spreads to other sites such as www.bookmaker.eu (which accepts US players). If at any time you find a line better at Bookmaker or another site than is offered at Pinnacle you might have a smart bet. The next step would be to return to this page and calculate Pinnacle’s No-Vig price. If the odds you’re getting are better than Pinnacle’s no-vig price chances are you have a +EV (positive expected value) wager.

Ever wondered how you are actually doing in sports betting?
Just like tracking your finances can be an eye opening experience (I spent how much at restaurants last month?!), tracking your bets can shed some light on how you are doing.
Download the free sports bet tracking spreadsheet below to get started:
Bet Tracker Spreadsheet: Instant Insights
If you want to measure your performance and see where you are succeeding and failing, you need to track it.
With this free tool, you can see your performance broken down by various dimensions.
Have a great ROI on betting NBA 2nd halves? Getting solid closing line value on NFL point spreads? This spreadsheet allows you to answer questions like this and more.
How to use the spreadsheet
While the spreadsheet is pretty straightforward, I’d like to walk you through how it works.
How to track sports bets
Everything lives in the “Bet Log” tab. This is the only place information is manually entered. Once the data is entered there, all other tabs will automatically populate.
In the “Bet Log” tab, blue columns are required while red columns are optional. The more information you input, the more useful the spreadsheet will be.
Entering things like the closing line, while slightly annoying, will also be the most important to your success.
How to analyze performance
Each tab will have different graphs and tables that show your performance. The beauty of this is that you can filter the data by any dimension you like.
Any yellow cell is an “input” cell that can be changed. All of these are dropdowns that are pre-populated based on the information you enter in the Bet Log.
How to add more leagues and teams
To add new leagues and teams, you will do so in the “REF” tab. This tab holds all of the lookup information for the dropdowns throughout the spreadsheet.
Gambling Spread Calculator Vs
Again, the cells available to modify are in yellow. You can add the following dimensions:
- Leagues (ex: WNBA)
- Teams (ex: Chicago Sky)
- Tags (ex: 2nd half)
Bet Tracker Spreadsheet Metrics
Gambling Spread Calculator Monthly
Deciding what to track is important in determining how you measure success. The spreadsheet tracks the following key metrics:
Closing Line Value
Closing line value (CLV) is a measure of how much better or worse the odds you bet at were compared to where they closed.
If you believe the markets you are betting into are efficient (NFL point spreads, MLB moneylines, etc.), then CLV is a great predictor of long term success.
All you need to do is input the odds you placed your bet at as well as where the odds closed. Preferably you use a market making sportsbook like Pinnacle to decide what the “true” closing line was.
Profit
Profit is about as simple as it gets. Are you making or losing money?
While this is the “bottom line”, surprisingly it isn’t always predictive of long term success. Still, you will obviously want to see how much money you have made or lost.
ROI
This is what most people tend to look at. It is a measure of how profitable you are relative to how much you are risking.
While at the end of the day, the money in your pocket is what matters, this metric focuses more on results rather than process and is a measure of efficiency.
Gambling Spread Calculator Chart
ROI isn’t as predictive of long term winning as CLV, but is useful to track to see where you stand.
Risk
This one is simple, yet will likely give you insights into where you are putting your money.
If you have a model, does it consistently value the Dallas Cowboys differently than the market? Thus making many of your bets on the Cowboys? Analyzing your risk by league/team/bet type can give you these types of answers.
Bankroll
Bankroll will track our running total of how much money you have in your accounts across all sportsbooks. You can also see this trended over time to help you see any changes in your betting strategy and how that has affected your bankroll.
It is very useful to see, at a glance, where your money lies. Is 95% of our bankroll at FanDuel? Maybe you should shift some to DraftKings.
Bet Tracker Spreadsheet Dimensions
Having these metrics available is important, but insights really come from slicing the data by different dimensions.
League/Team
Tracking your performance by league or team can give you clues into where your strengths or weaknesses are.
Do you watch every second of every New York Knicks game? Think you have an edge on Knicks games? You can find out using the spreadsheet.
Same goes for leagues. Do you follow NFL closely but use strictly numbers for NCAA Basketball? Compare the performance of the two and see what’s working.
Bet Type
Looking at performance by bet type can also shed some light on your process, especially if it is model driven.
Track your performance by the following bet types:
- Spread
- Moneyline
- Total
- Prop
- Future
You can also use the “Tag” field to designate special types of bets. For example, if you want to see your performance on moneylines for NBA 2nd halves, you would put “2H” (or something similar) in the Tag field and “moneyline” in the bet type field.
Date
A common way to analyze performance is to look at metrics trended over time.
Look at any of the metric/dimension combinations above trended over any time period you’d like.
Want to see your performance over the last 14 days? Or how about the last 12 weeks? Both are possible here.
