Calculations

Here are sample calculations that show how our results are calculated. You can obtain the results directly from our calculators or tables pages; this is simply the mathematics behind the calculators.

Expected Value

The expected value is calculated by adding the expected value of each possibility:

Now for our Pinnacle Sports example we consider the neutral line case where we can either win or loss and each is equally likely:

So our expected value equation for this example becomes:

So for a $100 bet at Pinnacle Sports we get:

Now we can use the same equation for a Sport Select Pro-Line that has win, lose and tie option that are all equally likely and 2.5 decimal odds across all three. You have to parlay at least two games on Pro-Line. We will now do a two game example below; because the ticket is parlayed and has three choices we make the following changes:

The simplification process above is only valid for the neutral lines, for any line you can use the following general equation:

Break Even Calculations

To find the break even probabilities we set the EV equation equal to zero and solve for the desired variable:
