Powerball vs Mega Millions: Which One Should You Actually Play?

Mega Millions has slightly better jackpot odds — 1 in 290,472,336 versus Powerball's 1 in 292,201,338 — but that 0.6% edge is meaningless in practice. The real differences are price and payback: a Powerball ticket costs $2 and returns 16.0% of its price through non-jackpot prizes, while a $5 Mega Millions ticket returns 22.3% thanks to its mandatory multiplier. Powerball is cheaper per play, rolls to a winner faster, and has produced far bigger jackpots. Neither game is beatable, so the honest question isn't which one you can win — it's which one wastes less of your money along the way.

Key takeaways

• Jackpot odds are 1 in 292,201,338 (Powerball) versus 1 in 290,472,336 (Mega Millions) — Mega Millions is better by about 0.6%, which is statistically irrelevant.
• Overall odds of winning any prize are 1 in 24.87 for Powerball and 1 in 23.07 for Mega Millions.
• A Mega Millions ticket costs $5 against Powerball's $2 — 150% more per play.
• Per dollar staked, Mega Millions returns more: 22.3% of ticket price from non-jackpot prizes versus 16.0% for Powerball.
• Powerball reaches a jackpot winner faster: an average roll run of 18.3 draws (45 days between wins) versus 20.7 draws (71 days) for Mega Millions.
• Powerball has produced the bigger prizes — a largest-ever jackpot of $1.8 billion against Mega Millions' $1.22 billion, and 15 of the 20 largest jackpots on record.

The jackpot odds are nearly identical

Both games use a "5 white balls plus one special ball" structure, and the total combination count comes out almost the same.

Powerball draws 5 white balls from a pool of 69 and one red Powerball from 1–26. There are 11,238,513 ways to pick five numbers from 69, and each of those pairs with any of 26 Powerballs: 11,238,513 × 26 = 292,201,338.

Mega Millions draws 5 white balls from 70 and one Mega Ball from 1–24. That's 12,103,014 white-ball combinations × 24 Mega Balls = 290,472,336.

So Mega Millions has 1,729,002 fewer combinations. Dividing one by the other, Powerball's number is 1.006 times larger — Mega Millions is 0.6% "easier." If you played one Mega Millions ticket a week for a thousand years, that edge would still not have shown up in your life. Anyone framing 290 million versus 292 million as a reason to pick a game is selling you something. For a fuller sense of what these denominators mean physically, our breakdown of what 1 in 292 million actually looks like is a better use of your time than comparing the two.

One number does make the gap concrete: buying every combination once would cost $584,402,676 in Powerball tickets (292,201,338 × $2) but $1,452,361,680 in Mega Millions tickets (290,472,336 × $5). The odds are a wash. The price isn't.

Every prize tier, side by side

Here's where the games genuinely diverge. Each tier below shows the odds of hitting it on a single ticket, the prize, and that tier's contribution to expected value — prize divided by odds. Add the contributions and you get what the ticket returns excluding the jackpot.

Powerball ($2 ticket, 5/69 + 1/26)

Match	Odds (1 in)	Prize	EV contribution
5 + Powerball	292,201,338	Jackpot	varies
5 white	11,688,053.52	$1,000,000	$0.0856
4 + Powerball	913,129.18	$50,000	$0.0548
4 white	36,525.17	$100	$0.0027
3 + Powerball	14,494.11	$100	$0.0069
3 white	579.76	$7	$0.0121
2 + Powerball	701.33	$7	$0.0100
1 + Powerball	91.98	$4	$0.0435
Powerball only	38.32	$4	$0.1044
Total (non-jackpot)	1 in 24.87 any prize	—	$0.3199

Mega Millions ($5 ticket, 5/70 + 1/24, base prizes before multiplier)

Match	Odds (1 in)	Base prize	EV contribution
5 + Mega Ball	290,472,336	Jackpot	varies
5 white	12,629,232.00	$1,000,000	$0.0792
4 + Mega Ball	893,761.03	$10,000	$0.0112
4 white	38,859.18	$500	$0.0129
3 + Mega Ball	13,965.02	$200	$0.0143
3 white	607.17	$10	$0.0165
2 + Mega Ball	665.00	$10	$0.0150
1 + Mega Ball	85.81	$7	$0.0816
Mega Ball only	35.17	$5	$0.1422
Total (non-jackpot)	1 in 23.07 any prize	—	$0.3728

Two things stand out. First, Mega Millions pays substantially more in the middle tiers — $500 for four white balls versus Powerball's $100, $200 for three-plus-special versus $100. Powerball's mid-table prizes are thin.

Second, both games are bottom-heavy. In Powerball, the two cheapest tiers ($4 for the Powerball alone, $4 for one white ball plus the Powerball) contribute $0.1479 of the $0.3199 total — 46% of all non-jackpot value comes from $4 prizes. Mega Millions is similar: its two smallest tiers account for $0.2238 of $0.3728, or 60%. Most of what you get back, you get back four or five dollars at a time.

Price is the real difference

Expected value only means something relative to what you paid. Here's the same data normalized.

Metric	Powerball	Mega Millions
Ticket price	$2.00	$5.00
Odds of any prize	1 in 24.87 (4.02%)	1 in 23.07 (4.33%)
Non-jackpot EV (base)	$0.3199	$0.3728
Non-jackpot EV (with multiplier)	$0.3199	$1.1156
Return from small prizes	16.0%	22.3%
Gap the jackpot must cover	$1.6801	$3.8844

Powerball returns 16.0% of your $2 through non-jackpot prizes ($0.3199 ÷ $2.00). Mega Millions returns 22.3% of your $5 ($1.1156 ÷ $5.00). Per dollar staked, Mega Millions is the better small-prize game by a clear margin — roughly 40% more of your money comes back in ordinary winnings.

But note the last row. Because a Mega Millions ticket costs more, the jackpot has to make up a bigger absolute hole: $3.8844 per ticket versus $1.6801 for Powerball. That single fact drives everything in the break-even section below.

The Mega Millions multiplier changes the small-prize math

Every Mega Millions ticket includes a multiplier that applies to all non-jackpot prizes. You don't choose it and you can't decline it — it's baked into the $5 price.

Multiplier	Odds (1 in)
2X	2.1
3X	3.2
4X	8.0
5X	16.0
10X	32.0

Weighted across those probabilities, the average multiplier is 2.99x. Applied to the base non-jackpot EV of $0.3728, that gives an effective $1.1156 per ticket — and that's the number that produces the 22.3% return rate.

In practice this means the tier table above understates Mega Millions considerably. A Mega Ball-only win pays $5 at base, but averages about $14.95 once the multiplier lands (5 × 2.99). Four white balls averages roughly $1,495 rather than $500. The multiplier is the single strongest argument for Mega Millions, and it's worth understanding before you dismiss the game on ticket price alone. If you want to run these figures against a specific jackpot amount, the Expected Value Calculator does the arithmetic for both games at once.

The catch: the multiplier is why the ticket costs $5 instead of $2. You're not getting a free upgrade — you're prepaying for it, and the math above shows you get about 22 cents of the 100 back.

Jackpot size and how often they roll

This is where Powerball wins decisively.

Measure	Powerball	Mega Millions
Draws in dataset	1,981 (from 2010-02-03 to 2026-08-03)	2,365 (from 2003-12-05 to 2026-07-31)
Draws under current matrix	1,389 (5/69 + 1/26)	914 white pool; 138 current Mega Ball pool
Jackpot wins analyzed	20	13
Average winning jackpot	$462,515,000	$545,384,615
Smallest winning jackpot	$20,000,000	$60,000,000
Largest jackpot ever	$1,800,000,000	$1,220,000,000
Average roll run	18.3 draws	20.7 draws
Median roll run	15 draws	20 draws
Longest roll run	47 draws (ended 2025-12-24)	40 draws (ended 2025-11-14)
Average days between wins	45	71

Mega Millions has the higher average winning jackpot at $545,384,615 versus $462,515,000, which sounds like a point in its favor. It isn't quite. That average is pushed up by Mega Millions' higher starting floor — its smallest recorded winning jackpot was $60,000,000 against Powerball's $20,000,000 — not by bigger peaks.

At the top end Powerball dominates. Of the 20 largest jackpots on record, 15 are Powerball. Powerball has crossed a billion dollars 13 times in that list; Mega Millions three times. The largest Powerball prize, $1.8 billion on September 6, 2025, is nearly 50% larger than the biggest Mega Millions jackpot of $1.22 billion on December 27, 2024. Our survey of every billion-dollar jackpot covers how rare those runs really are.

Powerball also resolves faster. Its average roll run is 18.3 draws and its median is 15, versus 20.7 and 20 for Mega Millions. Combined with three draws a week instead of two, that's 45 days between Powerball jackpot wins against 71 for Mega Millions — Mega Millions takes over half again as long. Only 15% of Powerball roll runs end in under 10 draws, compared with 31% for Mega Millions, so Mega Millions has more short runs but also drags longer on the ones that go.

When a ticket is worth buying

A ticket has positive expected value when the jackpot is large enough to cover the gap left by the small prizes. But "large enough" depends entirely on which assumptions you're honest about.

Assumption	Powerball break-even	Mega Millions break-even
Advertised annuity, no tax, no split	$491 million	$1.13 billion
Cash value (~50% of annuity), no tax	$982 million	$2.26 billion
Cash value + 37% federal tax	$1.56 billion	$3.58 billion
Cash + tax + split risk	$2.67 billion	$4.96 billion

Read the bottom row carefully. Powerball needs $2.67 billion to break even once you account for taking cash, paying federal tax, and the chance of splitting with another winner at high sales volume — and its largest jackpot ever was $1.8 billion. Mega Millions needs $4.96 billion against a record high of $1.22 billion. Neither game has ever offered a genuinely positive-EV ticket under realistic assumptions.

Powerball is closer, though. It has crossed the $1.56 billion cash-plus-tax line at least once — the $1.8 billion draw — while Mega Millions has never come within $2.3 billion of its equivalent threshold. The reason is the price denominator: Powerball only needs to cover $1.6801 of gap per ticket, Mega Millions $3.8844.

Mega Millions does have one structural advantage at the top: because it sells fewer tickets during comparable runs, its split factor is more forgiving — you'd expect to keep about 72.3% of a jackpot at roughly 200 million tickets sold, versus 58.3% for Powerball at around 350 million. Better to win a smaller jackpot alone than a bigger one three ways. The tax side matters even more than the split side, and our guide to what you actually take home walks through why the advertised number and the deposited number are so far apart. For the general framework behind all of this, see when a lottery ticket is actually worth buying.

Draw nights and the weekly budget

Powerball draws three nights a week — Monday, Wednesday and Saturday. Mega Millions draws two, Tuesday and Friday. In the current-matrix data that's 136 Powerball Mondays, 135 Wednesdays and 135 Saturdays against 135 Mega Millions Tuesdays and 135 Fridays.

If you play every draw, one ticket each, Powerball costs $6 a week ($2 × 3) and Mega Millions costs $10 ($5 × 2). Over a year that's $312 versus $520 — Mega Millions is about two-thirds more expensive to follow, despite offering fewer chances to play.

Flip it and hold spending fixed. On a $10 weekly budget you can buy 5 Powerball tickets or 2 Mega Millions tickets. Over a year:

• Powerball: 260 tickets, giving a jackpot chance of 260 in 292,201,338, or about 1 in 1,123,851.
• Mega Millions: 104 tickets, giving 104 in 290,472,336, or about 1 in 2,793,003.

At equal spend, Powerball gives you roughly 2.5 times the jackpot exposure — purely because the tickets cost less than half as much. Meanwhile the same $520 returns an expected $83.20 in Powerball small prizes (16.0%) but $115.96 in Mega Millions small prizes (22.3%). That's the trade in one line: Powerball buys more jackpot lottery tickets per dollar; Mega Millions gives more of your dollars back.

What the frequency data can and can't tell you

Both games publish per-day and per-number statistics, and both get misread constantly.

Game	Draw night	Draws	Jackpot wins	Win rate
Powerball	Monday	136	7	5.1%
Powerball	Wednesday	135	5	3.7%
Powerball	Saturday	135	8	5.9%
Mega Millions	Tuesday	135	8	5.9%
Mega Millions	Friday	135	5	3.7%

Saturday Powerball has produced 8 jackpot wins to Wednesday's 5. Tuesday Mega Millions has produced 8 to Friday's 5. Both spreads are three wins out of 135 draws. That is noise, and nothing more. No draw night, number, or selection method changes your odds of winning a jackpot — the odds are fixed by the matrix and are identical on every draw. Frequency data describes what already happened; a random draw has no memory of it.

The same applies to "hot numbers." Any count you see must be scoped to the right matrix window or it's meaningless. Powerball's counts are only comparable across the 1,389 draws under the current 5/69 + 1/26 setup — anything older used a different ball pool. Mega Millions is messier still: the white-ball pool has held at 1–70 for 914 draws, but the Mega Ball pool dropped from 25 to 24 in April 2025, so only 138 draws reflect the current special-ball odds. A Mega Ball frequency table drawn from all 2,365 draws in the dataset is comparing numbers that didn't face the same competition. If you want to see this handled properly, our breakdown of the most frequent Mega Millions numbers under the current game scopes each count to its correct window.

There is one thing selection genuinely affects, and it isn't odds — it's splitting. Picking numbers that lots of other people also pick (birthdate-heavy combinations under 31, patterns on the slip, sequences) doesn't reduce your chance of winning, but it raises the chance that if you win, you're dividing the prize. That's a real effect on the size of your payout, not on your probability of getting one.

Pick this if you care about X

There's no single verdict here, because the two games are optimized for different things.

Play Powerball if you want the biggest possible prize

Powerball holds 15 of the 20 largest jackpots on record, has passed $1 billion 13 times in that list, and set the record at $1.8 billion. Mega Millions' ceiling is $1.22 billion. If you're only interested when the number gets absurd, Powerball is where absurd happens.

Play Powerball if your budget is fixed and you want more entries

At $2 a ticket against $5, the same money buys 2.5 times as many chances. On $10 a week that's 260 tickets a year versus 104 — a jackpot exposure of about 1 in 1,123,851 versus 1 in 2,793,003.

Play Mega Millions if you want more money coming back

The mandatory 2.99x average multiplier lifts the effective non-jackpot return to 22.3% of ticket price against Powerball's 16.0%. Mega Millions also pays more in the middle: $500 base for four white balls versus $100, and $200 base for three-plus-Mega-Ball versus $100. If your realistic outcome is small wins — and it is — Mega Millions is the better-constructed game.

Play Mega Millions if you'd rather not share

With fewer tickets sold during comparable runs, the expected retained share of a Mega Millions jackpot is about 72.3% versus roughly 58.3% for Powerball. You can't improve your odds, but you can improve what a win would be worth.

Play Powerball if you want the wait to be shorter

Average roll run of 18.3 draws and 45 days between jackpot wins, against 20.7 draws and 71 days for Mega Millions. Powerball resolves; Mega Millions accumulates.

Play neither as an investment

Under cash value, 37% federal tax and split risk, Powerball would need a $2.67 billion jackpot to break even and Mega Millions $4.96 billion. Neither has ever happened. Both games are entertainment with a known, priced-in cost — 84 cents on the Powerball dollar and about 78 cents on the Mega Millions dollar, before any jackpot consideration. Budget for that cost the way you'd budget for a movie ticket, and don't increase your spend to chase a loss. Before a big draw, it's worth spending two minutes with the Expected Value Calculator to see exactly what the current jackpot is and isn't worth.

Frequently asked questions

Which lottery has better odds, Powerball or Mega Millions?

Mega Millions has marginally better jackpot odds at 1 in 290,472,336 versus Powerball's 1 in 292,201,338 — an edge of about 0.6%, which has no practical meaning. Mega Millions also has better overall odds of winning any prize, 1 in 23.07 against 1 in 24.87. But a Mega Millions ticket costs $5 versus $2, so Powerball gives you 2.5 times as many entries per dollar spent.

Why does Mega Millions cost $5 when Powerball costs $2?

The $5 Mega Millions price includes a mandatory prize multiplier applied to every non-jackpot win, ranging from 2X to 10X and averaging 2.99x. That raises the effective non-jackpot expected value from $0.3728 to $1.1156 per ticket, or 22.3% of the ticket price, compared with 16.0% for Powerball. You're prepaying for the multiplier rather than receiving it free — but per dollar staked, it does return more.

Which game has bigger jackpots?

Powerball, by a wide margin at the top. Its largest jackpot ever was $1.8 billion, drawn September 6, 2025, versus $1.22 billion for Mega Millions on December 27, 2024. Powerball holds 15 of the 20 largest jackpots on record. Mega Millions has the higher average winning jackpot at $545,384,615 versus $462,515,000, but that reflects a higher starting floor rather than bigger peaks.

Is either game ever a good expected-value bet?

Not under realistic assumptions. Powerball would need a $2.67 billion jackpot to break even once you account for cash value, 37% federal tax and the chance of splitting the prize; Mega Millions would need $4.96 billion. The largest jackpots ever offered were $1.8 billion and $1.22 billion respectively. Powerball has crossed the simpler $1.56 billion cash-plus-tax threshold once, but never the full-assumption line.

Does picking certain numbers improve my chances?

No. Nothing changes your odds of winning a jackpot — they're fixed at 1 in 292,201,338 for Powerball and 1 in 290,472,336 for Mega Millions on every single draw, regardless of which numbers you choose or how you choose them. Number selection can affect how likely you are to split a prize with other winners, since popular combinations get picked more often, but it cannot affect whether you win.

How often does each game reach a jackpot winner?

Powerball averages a roll run of 18.3 draws with a median of 15, working out to about 45 days between jackpot wins. Mega Millions averages 20.7 draws with a median of 20, roughly 71 days. Powerball's three weekly draws versus Mega Millions' two accelerate the difference. The longest recorded runs were 47 Powerball draws, ending December 24, 2025, and 40 Mega Millions draws, ending November 14, 2025.
