Half Point Calculator
All calculatorsThis calculator shows how much buying a half point moves your win probability and what the fair price becomes once you have bought it. Enter your win probability and the chance the game lands exactly on the number.
What it does. It prices what an extra half point is really worth, by turning the push chance at a key number into added win probability and showing the fair odds you should pay.
How to use it. Enter your current win probability at the whole number line and the push probability at that number. As a guide for the NFL, the 3 is worth about 9 to 10 percent and the 7 about 5 to 6 percent.
Why it matters. Buying or selling a half point only pays off when the price is below what the point is truly worth. This shows that break even line, so you do not overpay to move off a key number.
