Get your calculator out ,
enter 100 , then the " / " sign (which works like the division ÷ sign), then 130 for -130 moneyline, and you'll get .769 with a bunch of numbers following. Round it off to .77, and that's your payout for an even 100 dollar bet. Just simply times .77 by 2 if it's a $200 bet, times 3 if it's $300.
I am against the concept of "having to bet 130 to win 100 dollars" or "i dont like to lay the wood because i have to risk 130 to win 100, and if i lose, i lose 130." That's a paranoid gamblers approach . Instead, use your mathematical capacity of your brain, if you are betting football sides, just calculate winning 91 bucks when you place a $100 bet on a regular pointspread bet of the standard -110 odds casinos post.
I do all my standard 1 unit bet gauges with the $100 risk, win 91 dollars on a standard -110, or 83 dollars on a -120.
