Powerball vs Mega Millions: Odds and Jackpot Comparison

Updated: 2026-11-02

Powerball's jackpot odds are 1 in 292,201,338 and its overall odds of winning any prize are 1 in 24.87. To compare it with Mega Millions fairly, put the same measures side by side: jackpot odds, overall odds, prize tiers, payout options and tax.

The short answer

Powerball's jackpot odds are 1 in 292,201,338, and the odds of winning any prize are 1 in 24.87, according to the official Powerball prize chart (checked April 2026). Those two numbers, jackpot odds and overall odds, are the first things to line up against Mega Millions.

This guide covers the Powerball side in full detail. We do not quote Mega Millions figures here, because we would rather send you to the official Mega Millions rules than risk printing an outdated number. Odds and jackpots are only half the picture, so the guide also covers the points that change what a win is actually worth: fixed versus variable prizes, optional multipliers, annuity versus cash, and tax.

One thing applies to both games: every draw is random. Neither game's odds can be improved by how you choose numbers or when you play.

How to compare two lotteries fairly

Headline jackpots are the least useful way to compare. A jackpot is set by sales and rollovers, so it changes from draw to draw. The structure of the game stays the same. Compare these measures instead:

Read the two odds figures together. Jackpot odds tell you how rare the top prize is. Overall odds tell you how often something is won, and that includes small prizes that only return a few dollars. A game can look generous on overall odds and still have very long jackpot odds, and the reverse can also be true.

Powerball odds, tier by tier

Powerball has nine prize tiers. The official chart gives these odds and base prizes:

Three things stand out:

• The second tier is much more likely than the jackpot. Matching all five white balls without the Powerball pays $1,000,000 at 1 in 11,688,053.52, about 25 times more likely than the jackpot.
• Most winning tickets are small. The two lowest tiers each pay $4, and the Powerball-only tier alone is about 1 in 38.
• The 1 in 24.87 figure combines all nine tiers. It does not mean one ticket in 25 wins something worthwhile.

Fixed prizes are not always fixed

In most US jurisdictions, Powerball prizes below the jackpot are advertised as fixed amounts. California is the exception named on the official site. There, lower-tier prizes are pari-mutuel, meaning they vary with sales and the number of winners. A ticket bought in California can therefore pay something different from the amount printed on the chart.

If you compare any two lotteries, check whether each one's lower prizes are fixed or pari-mutuel in the place where the ticket is bought.

Power Play: what it changes and what it doesn't

Power Play is Powerball's optional multiplier. It has strict limits:

• It applies only to non-jackpot prizes. The jackpot is never affected.
• The second tier always pays $2,000,000 with Power Play, instead of $1,000,000.
• Other non-jackpot prizes are multiplied by whatever Power Play number is drawn for that draw.
• Multipliers can be 2X, 3X, 4X or 5X. A 10X can appear only when the advertised annuity jackpot is $150 million or less.

The official multiplier odds depend on whether 10X is in play:

• Draws that include 10X: 10X is 1 in 43, 5X is 2 in 43, 4X is 3 in 43, 3X is 13 in 43 and 2X is 24 in 43.
• Draws without 10X: 5X is 2 in 42, 4X is 3 in 42, 3X is 13 in 42 and 2X is 24 in 42.

The multiplier is drawn separately, so it cannot be known in advance. It also does nothing for the 1 in 292,201,338 jackpot odds. If a Mega Millions-style add-on is part of your comparison, check exactly which prizes it touches and whether it has a jackpot-size condition.

Jackpot size is not what you take home

The advertised jackpot and the amount a winner receives are two different numbers. This is true for both games.

Annuity versus cash option

A Powerball jackpot winner chooses between two payouts:

• Annuity: 30 payments, one immediately and then one each year for 29 years.
• Cash option: the jackpot's cash value paid in one go.

The cash value is not a fixed percentage of the advertised jackpot. According to the Powerball site, it depends on the cash actually held in the jackpot fund and on market conditions. Two jackpots of the same headline size can therefore have different cash values. When comparing jackpots between games, compare the cash value as well as the headline figure.

Tax withholding

Tax cuts into any large prize, and the rules differ by residency:

• US residents: the IRS says lottery winnings above $5,000 are generally subject to 24% federal withholding (IRS Publication 505). That is an advance payment, not the final bill. The real tax depends on your total taxable income, filing status, deductions and any state tax, so you may owe more or get a refund.
• Nonresident aliens: US-source gambling and lottery income is generally subject to 30% federal withholding, unless a valid tax treaty changes the result (IRS instructions for Form 1042-S).
• Paperwork for non-US winners: IRS Topic No. 419 points nonresident aliens to Form 1040-NR and Schedule NEC, with Publications 519, 515 and 901 as references (IRS Topic 419). US residents generally see federal withholding on Form W-2G.

These tax points apply to a US lottery prize in general, so they work the same way whichever of the two games you win. Your home country may also tax foreign winnings, so consider asking a tax adviser who knows your situation.

Claiming rules are set state by state

Some questions that players assume are answered federally are not:

• Anonymity, claim deadlines and where to claim are generally set by each state's lottery rules. The federal sources we reviewed do not set them.
• Foreign winners: we found no federal rule that bars a non-US person from collecting a lottery prize. Claim eligibility and ID requirements still follow the rules of the state where the ticket was bought.
• Buying through a courier: federal law (UIGEA, 31 U.S.C. 5362) does not make third-party ticket purchasing legal in every state. Whether it is allowed depends on state law and lottery regulations.

Because these rules can differ for each game and state, check them before you play, whichever lottery you choose.

A practical checklist

1. Write down both games' jackpot odds and overall odds from the official sources, and compare them like for like.
2. Check how many prize tiers each game has and what the lower tiers pay.
3. Find out whether lower-tier prizes are fixed or pari-mutuel where the ticket is sold.
4. Look up exactly what each optional multiplier does and does not cover.
5. Compare cash values as well as headline jackpots, and keep tax in mind.
6. Play only what you can afford to lose, since neither game's result can be predicted.
