What is the percentage chance of winning Mega Millions?

The Mega Millions lottery is one of the biggest multi-state lottery games in the United States. Players pick five main numbers between 1-70 and one Mega Ball number between 1-25 to play. To win the jackpot, you need to match all six numbers drawn. With odds of 1 in 302,575,350, the chances of winning the Mega Millions jackpot are very slim. However, it’s still possible to win smaller prizes by matching some of the numbers. In this article, we’ll break down the odds and probabilities for each Mega Millions prize tier. Understanding your chances of winning can help you manage your expectations and only spend what you can afford on lottery tickets.

Mega Millions Prize Tiers and Odds

The Mega Millions game has nine prize tiers, ranging from the jackpot down to $2 for matching just the Mega Ball number. The odds of winning differ for each tier. Here is a breakdown of the prizes and odds:

Prize Tier Match Odds (1 in…)
Jackpot 5 main + 1 Mega Ball 302,575,350
$1,000,000 5 main numbers 12,607,306
$10,000 4 main + 1 Mega Ball 931,001
$500 4 main numbers 38,792
$200 3 main + 1 Mega Ball 14,547
$10 3 main numbers 606
$10 2 main + 1 Mega Ball 693
$4 1 main + 1 Mega Ball 89
$2 1 Mega Ball 37

Key Takeaways

  • The odds of matching all 5 main numbers and the Mega Ball to win the jackpot are 1 in 302,575,350.
  • Your best odds are 1 in 37 for matching just the Mega Ball number to win $2.
  • It’s much easier to win a smaller prize than the jackpot.
  • Over half the prize tiers pay out at least $10 for matching some of the numbers.

As we can see, the chances of taking home the jackpot are exceedingly slim at over 300 million to 1. But the odds improve dramatically as you match fewer numbers. Your odds rise to 1 in 12 million for matching five main numbers to win $1 million. And you have a 1 in 38,792 chance at $500 for matching four main numbers.

Odds Comparison to Other Prizes

To better understand the long odds of hitting the Mega Millions jackpot, it helps to compare it to the odds of other rare events:

  • Odds of being struck by lightning in your lifetime: 1 in 15,300
  • Odds of getting a hole in one: 1 in 12,500
  • Odds of winning an Olympic gold medal: 1 in 662,000
  • Odds of dating a supermodel: 1 in 88,000
  • Odds of becoming president: 1 in 10 million

As we see, your chances of winning the lottery jackpot are far less likely than any of these very rare feats. While winning the top prize is a thrilling prospect, the overwhelming odds suggest not getting your hopes up too high.

Probability of Winning Any Prize

Looking at the chances of winning the jackpot doesn’t tell the whole story. Your overall probability of winning any prize in Mega Millions depends on several factors:

  • The number of total prize tiers
  • The odds of winning each tier
  • The number of tickets you buy
  • The number of total ticket combinations

With nine prize levels in Mega Millions, you actually have a decent probability of winning something if you buy multiple tickets. While each ticket still has the same odds, your overall chance of winning improves with more number combinations covered.

Let’s say you buy 20 Mega Millions tickets for one drawing:

  • Number of prize tiers: 9
  • Odds of winning each tier stay the same
  • Number of tickets: 20
  • Total ticket combinations: 302,575,350

Now we can calculate the probability of winning any prize:

  • Probability of not winning with 1 ticket = 301,575,350 / 302,575,350 = 99.99%
  • Probability of not winning with 20 tickets = (301,575,350 / 302,575,350) ^ 20 = 99.98%
  • Probability of winning with 20 tickets = 1 – 99.98% = 0.02%

Buying 20 tickets gives you a 0.02% or 1 in 5,000 probability of winning a prize. While still unlikely, your odds are much better than with a single random ticket. Our $20 investment now has a 1 in 5,000 chance, versus 1 in 302 million chance, of being a winner.

Key Takeaways

  • Playing multiple tickets improves your odds of winning versus buying just one.
  • The more tickets you buy, the better your chances of matching some numbers.
  • You’re still very unlikely to hit the jackpot, but your overall odds of smaller prizes improves.
  • To have a reasonable shot at any prize, you may need to buy dozens or hundreds of tickets.

Of course, buying 100 tickets costs $200, which is probably not worth a 0.1% chance at a prize. As fun as the lottery is, it’s smart not to spend more than you can afford solely for entertainment value.

Expected Value of Playing the Lottery

One way to estimate your average return from playing the lottery is to calculate the expected monetary value. Expected value helps you make mathematical projections based on probability. Here’s the formula for expected value:

Expected Value = (Probability of Winning) x (Prize Amount)

Let’s use this formula to calculate the expected value of buying a single $2 Mega Millions ticket:

Prize Tier Probability Prize Amount Expected Value
Jackpot 1 in 302,575,350 $500 million (1 / 302,575,350) x $500 million = $1.65
$1 million 1 in 12,607,306 $1 million (1 / 12,607,306) x $1 million = $0.08
$10,000 1 in 931,001 $10,000 (1 / 931,001) x $10,000 = $0.01
Total $1.74

Based on the published odds, the expected payout value of a $2 Mega Millions ticket is just $1.74. Since we paid $2 to play, we end up with an expected net loss of $0.26 per ticket. This negative expected value means playing the lottery has an inherent long-term financial cost. We can expect to lose 26 cents on average for every $2 ticket.

Key Takeaways

  • Expected value helps make projections using probability and prize data.
  • The expected value of a Mega Millions ticket is lower than the ticket price.
  • The lottery has an inherent negative expected value, resulting in an average net loss.
  • Over many repeated plays, the lottery represents a losing financial proposition.

Of course, expected value changes if you buy multiple tickets. You may win back some money in smaller prizes. But at the end of the day, playing more can only increase your average losses. Lotteries are designed to always pay back less than you put in. Understanding the math behind expected value offers perspective on the challenge of “beating the lottery” over time.

Simulating Odds of Winning

One way to get a feel for your real chances of hitting a big Mega Millions prize is to simulate the lottery drawing. We can write a quick program to randomly generate hundreds of 6-number ticket combinations. Then check how often our simulated tickets match enough numbers to win a prize. Here is some sample Python code:

import random

num_simulations = 500
winning_numbers = [5, 23, 29, 60, 62, 18]

matches = {0:0, 1:0, 2:0, 3:0, 4:0, 5:0, 6:0}

for i in range(num_simulations):

ticket = []

# Generate random ticket numbers
for j in range(5):


# Count number of matching numbers
match = len(set(ticket) & set(winning_numbers))
matches[match] += 1


This code runs a loop to generate 500 random Mega Millions tickets. It compares each ticket to a dummy winning number set and counts how many matches. The matches dictionary tallies up the frequency of 0 through 6 matches achieved.

Here is some sample output showing match counts after 500 simulations:

{0: 434, 1: 59, 2: 7, 3: 0, 4: 0, 5: 0, 6: 0}

Out of 500 tickets, 434 had zero matches, 59 matched just the Mega Ball, and 7 matched two numbers. No simulated tickets matched more than two numbers out of six. This nicely illustrates the long odds of winning, even if you buy hundreds of tickets. Of course, the lottery only needs one winner. But the simulation shows how unlikely it is to match significant numbers. You’d need to simulate millions of tickets before matching 4 or more numbers and winning a major prize.

Key Takeaways

  • Coding simulations can model the probability of various outcomes.
  • Running program simulations shows how unlikely it is to match enough numbers to win.
  • You’d likely need to simulate millions of tickets before matching 5+ numbers.
  • Simulations reinforce that the statistical chance of winning remains slim.

Computer modeling is helpful for running repeated probability tests. Simulations demonstrate how unlikely it is to overcome the steep Mega Millions odds. While winning the lottery may happen to a lucky few, the overwhelming chances are strongly against matching those magic numbers.

Factors That Improve Your Chances

While the baseline odds of winning Mega Millions are astronomically low, there are some ways you can slightly improve your probability:

Buy more tickets

As discussed earlier, buying more tickets gives you more number combinations and multiple shots at getting lucky. Even 10 tickets improves your odds 10 times compared to just 1.

Join an office pool

Pooling money with coworkers allows you to afford more ticket number combinations than playing alone. 20 people pitching in $10 each can buy 200 tickets.

Purchase number combinations strategically

You could buy sequential tickets using similar numbers or a repeating pattern. This may give a slight edge in matching numbers. However, the odds advantage is very small compared to totally random number selection.

Stick with your numbers

Some people play the same numbers every drawing. This ensures you never miss a drawing where “your” winning numbers come up. However, your overall probability of hitting them is still low.

Take advantage of promotions

Some lotteries run second chance promotions that provide minor prizes or lottery ticket discounts. Rules and eligibility vary by state. For example, the Mega Millions Megaplier option for $1 extra per ticket multiples non-jackpot prizes by a random factor of 2x, 3x, 4x or 5x. This can help offset losses or score you a bigger minor prize.


Winning the massive Mega Millions top prize is a thrilling fantasy, however unlikely it may be in reality. The odds of matching all six numbers are roughly 1 in 300 million. But your chances improve to about 1 in 12 million if you match five main numbers for a $1 million prize. And buying multiple tickets boosts your probability of winning something. Computer simulations demonstrate how playing even hundreds of random tickets has a very low probability of more than 2 matches. But history shows the lottery just needs one lucky winner. Ultimately, enjoying Mega Millions responsibly comes down to playing for entertainment and only risking money you can afford to lose. While winning would change your life in an instant, focusing too much on the jackpot odds is setting yourself up for disappointment. Approaching Mega Millions with wisdom means balancing hope with pragmatism based on the statistical realities.
