This is a calculator where is possible to calc the difference between two OODs. For example, the main idea is to compare the first ODD (1.50) for (yes) from the betting house A and the second ODD (3.50) for (no) from the betting house B in the same game. Putting these values in the calculator you will find a profit of 5% of the betting total.
