To keep from getting math intensive, I’ll simplify things and tell you to Google search “Moneyline Converter”, plug in 72.37%, and see in American odds format that this equates to a moneyline of -262. This means that each individual leg must win 72.37% of the time on average for the teaser bet to have neutral (break even) expectation.
In order to do any sort of statistical analysis of teasers, we need to ask ourselves “how often must each leg individually win to achieve a 52.38% win rate?” To calculate this, what we need to know is what number times itself equals 0.5238. This is how often “both” legs of a teaser must win for the bet to be break even. For example, a bettor risks $110 to win $100, the return is $210, so the math here is $110 risk/$210 return=0.5238 which is 52.38%. The formula used to calculate this is risk divided by return, where return equals stake plus win.
As you might already know, to break even at -110 you need to win 52.38% of your bets. Let’s start with 2 team 6 point (-110) teasers.
