How the Mega Millions jackpot odds are derived from the combinatorics of the game, what the prize tiers look like, and why no number-selection method can move those odds.
Mega Millions is played by choosing five white balls from a pool of 1 to 70 and one gold Mega Ball from a separate pool of 1 to 24. Matching all six wins the jackpot. That rule alone fixes the odds — no selection method changes them.
The jackpot math
The number of ways to choose 5 white balls from 70, ignoring order, is the combination C(70,5):
C(70,5) = 70! / (5! × 65!) = 12,103,014
Each white-ball combination can pair with any of the 24 Mega Balls, so the total number of distinct tickets is:
12,103,014 × 24 = 290,472,336
That makes the jackpot odds 1 in 290,472,336. Every specific ticket is one equally likely outcome among those 290 million, whether you pick birthdays, "overdue" numbers, or a random Quick Pick.
Note what the 2025 change did and did not do. Removing one Mega Ball improved the jackpot odds by about 4% — meaningful in a press release, invisible in practice. It also raised the ticket price by 150%. Per dollar spent, the change made a jackpot less accessible, not more.
The nine prize tiers
Every Mega Millions play now carries a randomly assigned multiplier of 2×, 3×, 4×, 5×, or 10×, applied to all non-jackpot prizes. The base prize column below is the 2× figure, since 2× is the most common multiplier at 1 in 2.13.
| Match | Prize at 2× | Prize at 10× | Odds |
|---|---|---|---|
| 5 white + Mega Ball | Jackpot (shared if multiple winners) | 1 in 290,472,336 | |
| 5 white | $2,000,000 | $10,000,000 | 1 in 12,629,232 |
| 4 white + Mega Ball | $20,000 | $100,000 | 1 in 893,761 |
| 4 white | $1,000 | $5,000 | 1 in 38,859 |
| 3 white + Mega Ball | $400 | $2,000 | 1 in 13,965 |
| 3 white | $20 | $100 | 1 in 607 |
| 2 white + Mega Ball | $20 | $100 | 1 in 665 |
| 1 white + Mega Ball | $14 | $70 | 1 in 86 |
| Mega Ball only | $10 | $50 | 1 in 35 |
Multiplier frequencies are 2× at 1 in 2.13, 3× at 1 in 3.2, 4× at 1 in 8, 5× at 1 in 16, and 10× at 1 in 32. California pays all tiers pari-mutuel, so prizes there differ from the fixed amounts above.

Putting 1 in 290 million in perspective
Odds this large resist intuition. A useful frame: the lowest tier, matching the Mega Ball alone, hits about 1 in 35 — roughly once a month if you play twice a week. The jackpot is about eight million times rarer than that. Buying more tickets helps only in strict proportion; ten plays make it 10 in 290 million, still effectively a rounding error, and now cost $50.
The overall odds of winning something are about 1 in 23. That number is doing a lot of work in advertising, and it is worth reading carefully: most of those wins are the $10 Mega-Ball-only tier, which does not cover the $5 ticket twice over. Winning a prize and coming out ahead are different events.
How Mega Millions compares to Powerball
The two games are close cousins. Both ask you to match five white balls plus one special ball, and both land near 1 in 290–292 million for the jackpot:
| Mega Millions | Powerball | |
|---|---|---|
| White balls | 5 of 70 | 5 of 69 |
| Special ball | 1 of 24 | 1 of 26 |
| Jackpot odds | 1 in 290,472,336 | 1 in 292,201,338 |
| Overall odds of any prize | 1 in 23 | 1 in 24.87 |
| Ticket price | $5 (multiplier included) | $2 ($3 with Power Play) |
| Lowest prize | $10 (×multiplier) | $4 |
The jackpot odds differ by less than one percent — a rounding error at this scale, and not a sensible basis for choosing between them. The meaningful differences are the ticket price and what the lower tiers pay. Mega Millions costs 2.5× more per play and pays more at the bottom; Powerball costs less and pays less. Neither is a good bet, and the comparison is about which entertainment you prefer at which price.
One consequence of these enormous odds is worth internalizing: across a lifetime of regular play, the overwhelmingly most likely outcome is that a player never hits the jackpot in either game. That is not pessimism, just arithmetic — and it is exactly why the lottery works best as occasional entertainment rather than a plan.
Can analytics beat these odds?
They cannot. The frequency and hot/cold charts on Lotto Pick HQ summarize history; they have no bearing on a probability set by the number of possible tickets. Each draw is independent, and the Mega Ball is drawn from its own machine with no connection to the white balls or to any past result. Our tools exist for curiosity and education, not prediction — see How Smart Picks Work for exactly what each mode does and does not do.
