The jackpot odds printed on a lottery game are a count of combinations. They are not a mood, a trend, or a number that moves because a ball has been quiet. This page shows where the two headline figures come from, what “1 in 24” actually refers to, and why adding tickets changes the chance in a straight line. It will not tell you whether a ticket is a good purchase. That depends on your money, your state, and what you want from a game that is built to pay out less than it takes in.
The Powerball jackpot figure
A Powerball ticket is one way of choosing 5 white balls from 69, plus 1 red ball from 26. The number of ways to choose 5 items from 69 is 11,238,513. Multiply by the 26 possible red balls and the matrix holds 292,201,338 different tickets. The prize chart publishes the jackpot odds as 1 in 292,201,338.00, which matches that count. If the drawing is fair, each of those tickets has the same chance, including a quick pick and a line you have played for years.
Five white balls with the wrong red ball is much more likely than the jackpot and still rare: 25 of the 26 red balls miss, so those odds are 25 in 292,201,338, or about 1 in 11,688,053.52. That is the $1 million tier before Power Play. The chart’s other tiers are the same kind of counting, with the number of ways to match exactly 4, 3, 2, 1, or 0 white balls, times the chance of hitting or missing the red ball.
Add up every way to win any prize and the chart says the overall chance is 1 in 24.87 on a $2 play. Most of that 1-in-24 is the small prizes. The Powerball-only prize, $4, is about 1 in 38.32 by itself. Someone who says “the odds are 1 in 24” and someone who says “the odds are 1 in 292 million” are talking about different events. Both numbers are on the same chart.
The Mega Millions jackpot figure
The current Mega Millions matrix is 5 white balls from 70 and 1 Mega Ball from 24. Five from 70 can be chosen in 12,103,014 ways. Times 24 Mega Balls, that is 290,472,336 combinations. The how-to-play page lists the jackpot odds as 1 in 290,472,336. Before April 8, 2025 the Mega Ball field had 25 numbers, and the consortium’s March 25, 2025 release put those older jackpot odds at 1 in 302,575,350. Removing one Mega Ball is why the jackpot got slightly easier and why the release put the overall chance of any prize at 1 in 23.
The same page shows that “any prize” is doing a lot of work. Matching only the Mega Ball pays $10, $15, $20, $25, or $50 depending on the multiplier, at odds of 1 in 35. The $10 million prize, five white balls with a 10× multiplier and no Mega Ball, sits at 1 in 12,629,232 before you even account for how rarely 10× is assigned. The multiplier odds are published separately: 2× is 1 in 2.13, so it is the usual print on a ticket, and 10× is 1 in 32.
Each drawing starts over
The machines draw a fresh set of balls. The official descriptions of both games treat each number in the field as equally likely on that draw. A white ball that has gone 40 drawings without appearing has the same chance on the next drawing as a white ball that appeared last night. For Powerball that chance is 5 in 69 for a specific white ball, because five white balls are drawn. For the current Mega Millions game it is 5 in 70. The Powerball red ball is 1 in 26. The current Mega Ball is 1 in 24.
Those single-ball chances are easier to picture than the jackpot, and they are the ones people try to bend with hot and cold lists. They do not bend. The hot and cold page uses this site’s own archive to show a real leader and a real long gap, and then compares those counts with the even-split number the matrix predicts. The gap is a fact about the past. The probability is a fact about the next draw.
Over a long series, counts drift toward the even split and never have to arrive. With 1,400 Powerball drawings, a white ball’s average count is about 1,400 × 5 / 69, a little over 100. Some numbers will sit above that and some below it. That spread is what randomness looks like. It is not a schedule.
More tickets, still a straight line
Two different Powerball combinations give you two chances in 292,201,338. Ten give you ten. A hundred give you a hundred. The increase is real and proportional. It does not compound, and it does not unlock a threshold where the ticket “starts to be likely.” One hundred tickets is still about 1 in 2.9 million for the jackpot. People underweight that because 100 feels like a serious effort and 292 million does not fit in the imagination.
Sharing a pool works the same way. Ten people who buy ten different lines own ten combinations. If one of those lines hits the jackpot, the share is a matter of their agreement, not a change in the drawing. If two of them accidentally bought the same line, the pool holds nine combinations, not ten.
A jackpot split works against the buyer in the other direction. The advertised prize is split among every ticket that matches it. The odds tables do not assume you will be the only winner. In a large jackpot, more tickets are sold, and the chance of sharing goes up at the same time as the headline number.
Why the headline jackpot is a poor expected-value shortcut
A common back-of-envelope test says a ticket is “worth it” when the advertised jackpot is larger than the odds times the ticket price. For a $2 Powerball ticket that rough product is about $584 million. The test is too crude to use, even as arithmetic.
- The advertised jackpot is the annuity, not the cash. The cash option is the amount in the prize pool, and it is lower. Taxes apply to both. The payout page describes the federal rules without telling anyone which option to take.
- The jackpot can be shared.
- The annuity is a stream of payments over many years. A dollar paid in year 29 is not a dollar in the hand tonight.
- The $2 or $5 price also buys the smaller prizes. Leaving them out understates the payout. Including them still leaves a game that, across all tickets, pays players less than ticket sales, because the selling lotteries keep a share for prizes, retailers, and public programs.
None of that is a moral lecture. It is a warning about a comparison that sounds mathematical and skips the cash amount, the taxes, and the split. LotteryMigo does not compute a “fair ticket price” for the current jackpot, because that number would depend on assumptions this site does not have: how many tickets will be sold, the tax situation of a winner, and the interest rate behind the annuity.
What the number pages are for
The Powerball and Mega Millions number pages report frequency, the last drawing, the current gap, and a few other facts from the NY Open Data file. They are a way to answer “when did 17 last appear?” without pretending the answer changes next Wednesday’s drawing. The home page uses the full file in one chart. The number pages separate the current matrix so a ball that did not exist in an older game is not judged against balls that did.
The generator on the home page draws a legal line for the current field: Powerball red balls from 1 to 26, Mega Balls from 1 to 24. A generated line is one combination. It has the same chance as a line copied from a fortune cookie.
