Juice Free Line Calculator?

[Wally Balls]

Hi,

Is there a calculator you can use to see what lines are with the vig removed?

For instance here is a Pinnace line on a tennis match:

+124
-140

I'd like some software or a website where I can input those numbers and it would give me the 'true' line with no juice.

I found this but it only gives a "Vig Free ML" result, which I think is the vig free line for the favorite, but it doesn't provide any line for the underdog...

Thanks

is this spam? link looks shady

obv, vig-free for the underdog is the opposite sign of the favorite

The site you listed is doing exactly what you are looking for. It shows the vig-free odds.

lol no that isn't my site, I just found it when Googling for this topic. I'm quite surprised all of these sports betting sites and forums don't have a calculator like I'm asking for to compare lines.

Ok so for the -140/124 line it says Vig Free ML 131

So that means the line is -131 for the favorite and +131 for the underdog?

That doesn't seem correct because on another site I found the equation to remove the vig from the lines and the result was different. Here is the equation:

Update: You are right, however I'll leave the below calculations since I typed them out, they might help somebody else. Thanks!


Step 1: Convert American Odds to Decimal Odds

-140 = 1.714285714
+124 = 2.24

Step 2: Convert Decimal Odds to % Chance

2.24 = 44.64285714
1.714285714 = 58.33333334

Step 3: Calculate Overround

= 2.97619048

Step 4: Calculate Total Vig

= 2.890173414

Step 5: Remove 50% of Vig % Chance

= 43.19777043
= 56.88824663

Step 6: Convert to Decimal

= 2.314934289
= 1.757832345

Step 7: Convert to American Odds

= -131
= +131

Just to be clear, this is true 100% of the time, regardless of the line?

So -1500 vig-free favorite = +1500 underdrog? +922=-922? +101=-101 etc?

Thanks!

Since there is no vig, then YES obviously the odds would be the same (+/-) for the favorite and dog. And yes that calculation you posted looks 100% correct.

You should be able to create your own personal excel document of a "Juice Free Line Calculator" after reading Ganchrow's "An Introduction to Betting Lines and Percentages".

vig-free favorite ML always equals vig-free underdog ML because the two probabilities equal 1

[dogman]

Use Gancrow's arbitrage calculator. In line 1 put the dogs line and line 2 the favorites line. Bet#2 gives you the no vig price.

Thanks everybody!

why doesn't SBR put up a vig-free calculator with its tools?

[CHUBNUT]

how you know where the vig is, its more often than not loaded more on one side

This is not true.

[CrimsonQueen]

This is not true.

Why do you say this is not true? If books shade one way or the other because of public interest, say, then they can increase their theoretical hold... So obviously books do shade lines. Maybe not "most" of the time as the poster implied, but I also wouldn't argue against this statement perhaps.

If typically a book's theoretical hold on a -110/-110 game is 4.55%, and the book shades the favorite by just 1%, and 60% of the public is on the shaded side, then they increase their theoretical hold to 4.9%.

[yisman]

I would not say that books never shade lines, but you can rest assured that if Pinnacle is showing -104/-104, for example, the no vig line is even.

[LT Profits]

Another way to look at it is that books shade the no-vig line before applying the vig. The vig itself is always the same hold% on both sides.

[yisman]

^ Agreed.

It does a quick no-vig calc as well as series calcs.

Pinny can shade lines too.

Enter this in your spreadsheet...

A1: (Blank)
A2: Home
A3: Away

B1: (Blank)
B2: (Insert line for home team)
B3: (Insert line for away team)

C1:  (Blank)
C2: =IF(B2>0,(100/(100+B2)),-B2/(100-B2))
C3: =IF(B3>0,(100/(100+B3)),-B3/(100-B3))

D1: (Blank)
D2: =C2/(C2+C3)
D3: =C3/(C3+C2)

E1: (Blank)
E2: =IF(D2<0.5,((1/D2)-1)*100,-100*D2/(1-D2))
E3: =IF(D3<0.5,((1/D3)-1)*100,-100*D3/(1-D3))

E2 and E3 will be your no-vig odds.

thank you very much
