How to calculate vig at matchbook?

[AgainstAllOdds]

I was just wondering how to go about doing this. I know they charge a 1% commision on bases and 2% on almost everything else, but there still has to be vig(even if not intented by the person offering the bet). How would one go about finding this?

Would you find the no vig price then add the 1% commision?

In the case of an underdog, multiply the available odds by (100%-commission%). For a fav, divide by (100%-commission%).

So, a MLB lineset of -150, +149 is the equivalent of -150/.99 and 149*.99, which is equal to a -151.515, +147.51 lineset.

For 2% commission use .98 instead of .99.

Not surprisingly, Mr. X is right on point.

You can also find these functions (among many others) in my http://forum.sbrforum.com/handicappe...ate-excel.html.

Of particular interest to the OP would probably be the =E2S(US exchange odds, exchange commission {default = 1%} ), which calculates sportsbook equivalent US odds given US exchange odds and commission, and =ExchUS2Hold(range of US Odds, Commission) which calculates theoretical hold given a range of exchange odds and commission.

Mr. X is lost somewhere in the mountains of California, I believe.
