Mega Millions Odds Explained

Mega Millions odds of hitting the jackpot are 1 in 290,472,336, according to the game’s official operator at megamillions.com. That single number is the one most people want, and it deserves to come first. It is not a rounded guess or a marketing figure — it is the exact count of possible number combinations in the game as it is played today.

That figure changed recently. Before April 2025, the odds were 1 in 302,575,350. Mega Millions removed one gold Mega Ball from the pool, dropping it from 25 balls to 24, and the jackpot odds improved. The first drawing under the new setup was Tuesday, April 8, 2025, as NBC News reported at the time.

The overall chance of winning any prize is about 1 in 23.07, per megamillions.com. Below, you will find where every one of those figures comes from, why a small change to one ball moved the math so much, and a few facts about this game that surprise almost everyone who hears them.

The current Mega Millions odds and prize numbers

Here are the verified figures from the official game operator and state lottery sites, plus the 2023 record for context. Base prizes are the starting amounts before the built-in multiplier printed on your ticket is applied.

Where the Mega Millions odds number actually comes from

You pick five white numbers from 1 to 70 and one gold Mega Ball from 1 to 24. Order does not matter on the white balls. There are 12,103,014 possible five-number white combinations. Multiply that by the 24 possible Mega Balls and you get 290,472,336 — every distinct ticket the game can produce.

That is the whole calculation. The Florida Lottery publishes a public PDF walking through the same arithmetic. Nothing is estimated or modeled. Mega Millions odds are simply a headcount of outcomes, which is why the figure is stated to the exact digit rather than as a range.

Why removing one ball changed so much

Here is the part most people find counterintuitive. Taking away a single Mega Ball — one ball, out of 25 — cut roughly 12.1 million combinations out of the game. That is because each Mega Ball carries an entire set of 12,103,014 white-ball combinations behind it.

So the removal shaved about 4 percent off the total, which sounds small, and yet it erased more possible tickets than most state lotteries contain in total. The overall odds of winning something also improved slightly, from about 1 in 24 to 1 in 23.07, according to megamillions.com.

The trade-off was the price. Tickets went from $2 to $5, as NBC News and Axios both reported. Mega Millions also folded the old $1 Megaplier add-on into the base ticket, so every $5 play now carries an automatic 2X, 3X, 4X, 5X or 10X multiplier on non-jackpot prizes.

What the multiplier does to smaller prizes

Because the multiplier is built in, there are no longer any break-even prizes. The lowest tier — matching the Mega Ball alone — has a $5 base, so the smallest possible win is $10 and the largest at that tier is $50, per the game’s published structure.

The same logic runs up the chart. A $500 base prize for four white balls becomes $1,000 to $5,000. The $1 million base for matching all five white balls without the Mega Ball becomes $2 million to $10 million. The jackpot itself is never multiplied.

• Mega Ball only: $5 base → $10 to $50
• Four white balls: $500 base → $1,000 to $5,000
• Five white balls: $1,000,000 base → $2,000,000 to $10,000,000
• Jackpot: not multiplied

Surprising but true facts about this game

The largest Mega Millions jackpot ever was $1.602 billion, won on a single ticket in Neptune Beach, Florida, in August 2023 — widely reported by the Associated Press and CBS News. It remains the game’s record. Larger totals you may have seen in 2025 headlines were Powerball, a separate game with separate odds.

Another one: the drawings are not held in Las Vegas or at a lottery headquarters. They take place at the WSB-TV studios in Atlanta, Georgia, twice a week on Tuesday and Friday nights at 11:00 p.m. Eastern.

And the game is not truly national. Mega Millions is sold in 45 states plus the District of Columbia and the U.S. Virgin Islands. A handful of states have never joined, so five states have no in-state Mega Millions sales at all.

Jackpot amount versus what a winner receives

The advertised jackpot is the annuity value, not a check. Mega Millions pays the annuity as one immediate payment followed by 29 annual payments, and each payment is 5 percent larger than the one before it. That escalation is designed to keep pace with rising costs over the 30-year run.

The cash option is smaller because it reflects what the lottery actually holds today — the amount it would take to buy the bonds funding the annuity. Winners can choose either, and federal tax withholding of 24 percent is applied to prize payments, per the official Mega Millions site.

Tax outcomes vary by state and by individual circumstances, and this is a description of how the payout mechanics work, not guidance for any specific situation. A licensed tax professional and your state lottery are the right places to take questions about a real prize.

Reading Mega Millions odds without fooling yourself

One in 23.07 sounds encouraging until you notice what is inside it. The overwhelming majority of those wins come from the smallest tiers — matching the Mega Ball alone, or one or two white balls plus the Mega Ball. The overall figure counts a $10 win exactly the same as a $1.6 billion one.

The Mega Millions odds also do not change based on how many people play, which numbers came up last week, or whether you buy a quick pick. Every combination is drawn from the same 290,472,336, every single drawing, independently.

What crowds do change is the split. More tickets sold means a higher chance two people match the same numbers and share the jackpot. That is why record jackpots and shared jackpots tend to show up together. The odds stay fixed; the payout does not.

Frequently Asked Questions

What are the current Mega Millions odds of winning the jackpot?

They are 1 in 290,472,336, per megamillions.com. That improved from 1 in 302,575,350 when the game removed one Mega Ball in April 2025, cutting the pool from 25 gold balls to 24.

Do the Mega Millions odds get better if I buy more tickets?

Each additional distinct combination is one more chance out of 290,472,336. Buying ten different plays makes it 10 in 290,472,336. The improvement is real but stays extremely small relative to the total.

Why did the ticket price go to $5?

Mega Millions raised the price from $2 to $5 with the April 2025 relaunch, as NBC News reported. The change funds a $50 million starting jackpot, larger base prizes, and a multiplier included in every play.

Is the advertised jackpot what a winner takes home?

No. The advertised figure is the 30-year annuity total. The cash option is a smaller lump sum, and 24 percent federal withholding applies to prize payments. State treatment varies — check with your state lottery.
