The Powerball is one of the most popular lottery games in the United States, with millions of people buying tickets each week hoping to win big. But what are your actual odds of winning if you buy 100 Powerball tickets? Let’s take a closer look at the math behind the game to find out.
How the Powerball Works
Each Powerball ticket costs $2 and players select 5 main numbers from 1-69 and 1 Powerball number from 1-26. To win the jackpot, you must match all 5 main numbers and the Powerball number. Smaller prizes are awarded for matching some of the numbers.
The Powerball drawings are held twice a week, on Wednesday and Saturday evenings. At each drawing, 5 white balls are drawn from one pool of 69 white balls and 1 red Powerball is drawn from a separate pool of 26 red balls.
The odds of winning the jackpot are calculated by multiplying the odds of picking each number correctly:
- Odds of picking the 5 main numbers correctly: 1 in 292,201,338
- Odds of picking the Powerball correctly: 1 in 26
- Odds of winning the jackpot: 1 in 292,201,338 x 1 in 26 = 1 in 292,201,338
So the odds of winning the jackpot with a single Powerball ticket are 1 in over 292 million. But how do the odds change if you buy multiple tickets?
Odds of Winning with Multiple Tickets
If you buy multiple Powerball tickets, you essentially have multiple chances to win which improves your odds. Let’s say you buy 100 Powerball tickets for one drawing:
- You have 100 chances to match the 5 main numbers instead of just 1
- You have 100 chances to match the Powerball number instead of just 1
So your odds of winning the jackpot with 100 tickets are:
- Odds of picking the 5 main numbers: 1 in (292,201,338/100) = 1 in 2,922,013
- Odds of picking the Powerball: 1 in (26/100) = 1 in 0.26
- Odds of winning the jackpot: 1 in (2,922,013 x 0.26) = 1 in 759,326
Therefore, the odds of winning the Powerball jackpot with 100 tickets is around 1 in 759,000. This is significantly better than the 1 in 292 million odds with just 1 ticket, but still unlikely.
Expected Number of Wins
Another way to look at Powerball odds is to calculate your expected number of wins based on the number of tickets you buy. This represents how many wins you would expect over a very long period of time if you kept playing consistently.
To calculate your expected number of jackpot wins, you take the odds of winning the jackpot and divide 1 by that number. So with 100 Powerball tickets, your expected number of jackpot wins is:
1 / odds of winning = 1 / 759,326 = 0.000001317
This means that if you bought 100 tickets for every Powerball drawing over millions of drawings, you would expect to win the jackpot 0.000001317 times. That works out to about 1 jackpot win every 759,000 drawings or roughly once every 5,800 years.
The table below shows the expected number of jackpot wins based on number of tickets purchased:
| Number of Tickets | Odds of Winning Jackpot | Expected Number of Jackpot Wins |
|---|---|---|
| 1 | 1 in 292,201,338 | 0.00000000342 |
| 10 | 1 in 29,220,133 | 0.000000342 |
| 100 | 1 in 759,326 | 0.000001317 |
| 1,000 | 1 in 75,933 | 0.0001317 |
As you can see, the more tickets you buy the better your chances of winning, but you would still need to buy a very large number of tickets to have a reasonable chance of winning even once.
Odds of Winning Smaller Prizes
While the odds of hitting the jackpot are still low even with multiple tickets, your odds of winning smaller Powerball prizes improve more significantly the more tickets you buy.
The odds of matching just the Powerball number or matching only 3 main numbers are much better compared to the jackpot. So buying 100 tickets gives you very good odds of winning something.
Here are the odds of winning some of the smaller Powerball prizes with 1 ticket versus 100 tickets:
| Prize | Odds with 1 Ticket | Odds with 100 Tickets |
|---|---|---|
| Match Powerball Only | 1 in 38 | 1 in 0.38 |
| Match 3 Main Numbers | 1 in 56 | 1 in 0.56 |
| Match 4 Main Numbers | 1 in 648 | 1 in 6.48 |
Buying 100 tickets makes it very likely you would win the prize for matching just the Powerball number. Your odds of winning a prize for matching 3 main numbers is better than 1 in 2. Overall, your odds of winning any prize with 100 Powerball tickets is around 1 in 6.
Still Low Odds of Winning
While buying 100 Powerball tickets significantly increases your odds compared to just 1 ticket, your overall odds of winning the jackpot are still extremely low at 1 in 759,000. You can expect to win the jackpot about once every 6,000 years if you buy 100 tickets for each drawing.
In reality, your odds are even lower because it’s unlikely you would play consistently for thousands of years. Many people only buy Powerball tickets when the jackpot gets especially high.
The bottom line is that while buying multiple Powerball tickets improves your chances, winning the big jackpot is still unlikely. The lottery is a game of very high odds.
Strategies to Improve Your Odds
If you want to increase your odds of winning the Powerball while still buying fewer than the 292 million tickets needed to guarantee a jackpot win, here are some tips:
- Buy tickets when the jackpot is higher – this increases ticket sales and makes it more likely the jackpot will roll down to lower prize levels if no one wins.
- Join/form a lottery pool – A group of people together buying even just 10-20 tickets improves odds significantly and is more affordable.
- Use lottery wheeling systems – These systems pick a range of numbers to cover more combinations.
- Stick to the same set of numbers – This helps you win prize money from matching some numbers even if you don’t hit the jackpot.

The Dream of Winning
While your odds of hitting the huge Powerball jackpot are slim to none even if you buy 100 tickets, many people still dream of that big win. Powerball tickets are inexpensive, the prizes are life-changing, and someone has to win eventually. Buying multiple tickets allows you to dream big while still understanding the math behind the long odds.
For most people, playing the Powerball is about having fun and entertaining that Cinderella-story fantasy, not necessarily sound investment strategy. As long as you set a budget and play responsibly, buying a few more Powerball tickets can help feed your inner winner.
Conclusion
Buying 100 Powerball tickets significantly increases your odds compared to just one ticket. However, even with 100 tickets your chances of winning the jackpot are still around 1 in 759,000. You can expect to hit the jackpot about once every 6,000 years if you buy 100 tickets for each drawing. So while buying more tickets helps, the Powerball odds are stacked heavily against you. For best results, join an office pool and use smart strategies like lottery wheeling. But the most important thing is to play for fun and not spend more than you can afford to lose.
