How Lottery Odds Work

Every lottery game publishes two kinds of odds, and they answer different questions. One tells you how hard it is to win the top prize. The other tells you how often a ticket wins something. Mixing them up is the most common way players misjudge a game, so it is worth getting them straight before you spend a dollar.

Jackpot odds and overall odds

Jackpot odds are the chance that a single play matches every number and wins the top prize. They are usually written as “1 in” a very large figure. Overall odds, sometimes called “any prize” odds, are the chance that a single play wins anything at all, including the smallest prize in the table.

Both figures are published by the game operator, and they are calculated per play, not per drawing. Buying a second ticket gives you a second play with the same odds, not a better one.

Real examples

Here are the published figures we have verified for five current games.

• Powerball: jackpot 1 in 292,201,338; any prize 1 in 24.87, based on a $2 play.
• Mega Millions: jackpot 1 in 290,472,336; any prize 1 in 23.
• Millionaire for Life: top prize 1 in 22,910,580; any prize 1 in 8.46.
• Lotto America: jackpot 1 in 25,989,600; any prize 1 in 9.63.
• 2by2: top prize 1 in 105,625; any prize 1 in 3.59.

Notice how far apart the two columns sit. A game can pay a small prize about one play in four and still make the top prize almost impossible to hit. Our Powerball and Mega Millions reviews show the full odds tables.

What “any prize” really means

The smallest prize in most lottery tables is a few dollars, and in many games it is the price of a ticket or less. Winning back what you paid counts as a winning ticket in the “any prize” figure, even though you are no better off.

That is why “any prize” odds are a fair measure of how often you will see a winning ticket, and a poor measure of how often you will come out ahead. Treat the figure as a count of wins, not a count of profits.

Why a better any-prize number is not a better game

Look again at the list above. 2by2 has the friendliest any-prize figure, 1 in 3.59, and the smallest top prize, $22,000 (or $44,000 on Tuesdays with a 7-draw ticket). Powerball has a much harder any-prize figure and a much larger jackpot ceiling.

Neither is the better game in the abstract. Frequent small wins and rare huge wins are different products. The odds are the price of that product, expressed in probability rather than dollars. A game that wins often has to keep its top prize small, because the prize pool is paid out of the same ticket sales.

So compare like with like. If you want to see a winning ticket regularly, look at the any-prize figure. If you care about life-changing money, look at the jackpot odds and the prize size together. Do not expect one game to be best at both.

Odds do not change with your habits

Each draw is independent. Numbers that came up last week are no more or less likely to come up this week. Picking birthdays, choosing a “due” number or playing the same set for years does not change your odds of matching. Quick Pick and chosen numbers have identical chances.

What can change is what you win if you do match. Popular number choices are more likely to be shared with other winners, which can split a prize. That affects the payout, not the probability.

How to read odds on any game

Check the operator’s own prize chart, not a retailer poster or a third-party site. Confirm the price the odds are based on, since add-ons and multipliers change both the cost and the prize table. Then ask what the smallest prize is. If it equals your ticket price, the any-prize figure overstates how often you profit.

State lottery pages publish the same data for their own draw games. You can find your state’s games and rules on our states page, and the full scoring approach we use to compare games is described in our methodology. For a side-by-side look at the two biggest jackpot games, see our Powerball vs Mega Millions guide.

One more caution concerns the way odds are rounded. Operators sometimes publish slightly different “any prize” figures for the same game across pages, because of rounding or because a state counts a particular prize tier differently. Maine and Minnesota, for instance, list Mega Millions at 1 in 23.07 while the game’s own site says 1 in 23. Treat small gaps like this as rounding, and use the operator’s own prize chart as the reference when you need a precise number.
