AC Value Calculator

Enter any set of numbers — a real draw, a ticket you're considering, a hypothetical combination — and get its AC value plus odd/even, big/small, and prime/composite classification. Works for any game's main numbers (pick the game to set the correct range).

This calculates a descriptive statistic about a number combination, not odds or a recommendation — every combination has the same odds of being drawn regardless of its AC value. See how lottery odds actually work.

What AC Value Means

AC value measures how "spread out" a set of numbers is: take every pairwise difference between the numbers, count how many of those differences are unique, then subtract (count of numbers − 1). For a standard 5-number game, AC ranges from 0 (numbers close to evenly spaced, like an arithmetic sequence) to 6 (every pairwise gap is different). See the AC value trend chart to see how AC values have actually landed across real drawings.
