Lump Sum vs Annuity: What a Billion-Dollar Jackpot Really Pays

Take the annuity on a $1.80 billion Powerball jackpot and you get exactly that headline number — paid out as 30 graduated installments across 29 years, starting around $27.1 million and ending around $111.5 million. Take the cash option and you get whatever is actually sitting in the prize pool, historically about half the advertised figure, so roughly $900 million before a dollar of tax. After federal tax at the top rate, that's about $1.13 billion spread over three decades versus about $567 million on the table today. The choice comes down to one question: can you reliably earn more than about 4.3% a year?

Key takeaways

• The annuity is 30 payments over 29 years, each about 5% larger than the last. On the $1.80 billion Powerball jackpot of September 6, 2025, that works out to roughly $27.1 million in year one and roughly $111.5 million in year 30.
• The cash option is the real money in the prize pool, historically around 50% of the advertised annuity — about $900 million on that same jackpot.
• Federal withholding is 24% at claim time, but a nine-figure prize lands in the 37% top bracket, so you owe the difference at filing. On $900 million cash, that's about $216 million withheld and roughly $117 million more due later.
• After federal tax alone, the annuity route totals about $1.134 billion and the cash route about $567 million — a nominal gap of roughly $567 million.
• Cash beats annuity only if you can earn more than roughly 4.3% a year, pre-tax, on the after-tax lump sum. That is the entire decision in one number.
• Your payout choice changes what you keep. It changes nothing about your odds of winning — nothing does.

The two structures, precisely

The advertised jackpot and the money the lottery actually holds are two different numbers, and most of the confusion around lump sum vs annuity lottery decisions starts right there.

The annuity: 30 payments, 29 years, 5% steps

When a jackpot is advertised at $1.80 billion, that is the total of 30 annual payments. The first arrives on claim; the remaining 29 arrive annually after that. Each payment is about 5% larger than the one before, which is why the schedule starts modestly relative to the headline and finishes very large.

The math is a geometric series. If the first payment is P and each subsequent payment grows 5%, the 30 payments together sum to P × (1.05^30 − 1) ÷ 0.05, which comes to P × 66.439. Set that equal to $1,800,000,000 and the first payment is about $27.09 million.

Behind the scenes, the lottery buys a portfolio of government securities that throws off exactly that payment stream. The advertised jackpot isn't cash the lottery has — it's what that bond portfolio will pay out by the end.

The cash option: what's actually in the pool

The lottery cash option is the amount the lottery would have spent buying those bonds. It's the present value of the annuity, and it's the money genuinely sitting in the prize pool right now.

Historically that lands around half the advertised annuity, which is the ratio we use throughout this article. It is not a fixed rule. The ratio moves with prevailing interest rates: when rates are high, a smaller pile of cash buys the same future payment stream, so the cash percentage drops. When rates fall, the cash percentage rises. Two jackpots with identical advertised totals in different rate environments will have visibly different cash values.

The $1.80 billion example, worked end to end

The largest jackpot in our dataset is the Powerball prize of $1.80 billion drawn on September 6, 2025 (winning numbers 11-23-44-61-62, Powerball 17), and it was won. It's also the largest winning jackpot recorded across the 406 Powerball draws in this dataset that carry jackpot figures. Here's what each route pays.

Route one: the annuity

Thirty payments, first payment about $27.09 million, each one 5% above the last. Every payment on a prize this size sits deep in the top federal bracket, so we apply 37% to each one.

Payment year	Gross payment	After 37% federal
1	$27,092,583	$17,068,327
5	$32,931,204	$20,746,659
10	$42,029,489	$26,478,578
15	$53,641,461	$33,794,121
20	$68,461,608	$43,130,813
25	$87,376,288	$55,047,062
30	$111,516,746	$70,255,550
All 30	$1,800,000,000	$1,134,000,000

Route two: the cash option

At the historical ~50% ratio, the cash value is about $900 million. Federal withholding takes 24% off the top the moment you claim — about $216 million — leaving roughly $684 million in the account. That withholding is not your tax bill. It's a deposit.

At filing, the prize is ordinary income taxed at the top marginal rate of 37%, so you owe roughly $333 million in total federal tax and cut a further check for about $117 million. Take-home: roughly $567 million.

	Annuity	Cash option
Advertised / actual value	$1,800,000,000	~$900,000,000
Federal withheld at 24%	$432,000,000 (across 30 payments)	$216,000,000
Additional federal owed at filing	~$234,000,000 (across 30 payments)	~$117,000,000
Approximate federal take-home	~$1,134,000,000	~$567,000,000
When you have it	Spread over 29 years	Within weeks

Two honest caveats on those numbers. First, the effective federal rate is slightly under 37%, because the first slice of income runs through the lower brackets before the top rate kicks in — on a nine-figure prize that difference is a rounding error, but it exists. Second, this covers federal tax only. If you want the layered version with withholding mechanics and filing timing, we cover that in what lottery winners actually take home after tax.

State tax is the variable we won't guess for you

Some states levy no income tax on lottery prizes at all. Others tax them as ordinary income at rates that vary widely, and a handful of cities add their own layer on top. Whether the prize is taxed where you bought the ticket, where you live, or both, depends on the specific pair of states involved.

We're deliberately not putting a number on this. The spread between the best and worst state outcomes on a $900 million cash option is enormous — easily tens of millions of dollars — and it is the single most jurisdiction-specific part of the whole calculation. Anyone who quotes you a precise state figure without knowing where you bought the ticket and where you're domiciled is guessing.

It also interacts with the annuity choice in a way people miss: an annuity locks you into 29 more years of state tax exposure that can change as legislatures change, while a lump sum crystallizes your state tax liability in a single year under known rules. That cuts both ways depending on where you sit.

You can run the federal side of any advertised jackpot through our Payout Calculator to see the cash and annuity figures side by side before you talk to anyone.

The real question: what return beats the annuity?

Here's the crux, and it's the part most coverage skips. Should I take the lump sum is not really a question about money now versus money later. It's a question about an implied rate of return.

The annuity is, functionally, a bond you're forced to buy. Take the cash and you're declining that bond in favor of investing the money yourself. So the honest comparison is: what annual return would your own portfolio need to earn to end up ahead?

Solve for the discount rate that makes the present value of those 30 growing payments equal the cash option. At a 50% cash ratio, that rate is about 4.28%. Below it, the annuity wins. Above it, the cash wins — and the gap compounds hard over 29 years.

Because the cash ratio moves with interest rates, so does the hurdle:

Cash value as % of annuity	Cash on a $1.80B jackpot	Return needed to beat the annuity
45%	$810,000,000	~5.02% per year
50%	$900,000,000	~4.28% per year
55%	$990,000,000	~3.63% per year
60%	$1,080,000,000	~3.05% per year

Read the table the right way. A lower cash percentage means a stingier lump sum, which raises the bar your investments must clear. A generous cash percentage means the annuity is comparatively weak and the hurdle drops.

Two things this table doesn't capture. It's pre-tax on the investment side, so investment income tax pushes the real hurdle higher than it looks. And it ignores inflation entirely — the 5% escalator in the annuity is roughly a hedge against price rises, which is precisely what a flat nominal comparison undersells.

The case for the annuity

The strongest argument for the annuity has nothing to do with returns. It's structural protection.

The pattern of large lottery winners losing most or all of the money within a decade is well documented, and the mechanism is rarely a bad investment. It's a combination of an unfamiliar sum, an unfamiliar social environment, and no institutional friction between an impulse and a wire transfer. The annuity supplies that friction. You cannot lend your brother-in-law money you don't have yet.

Three concrete points in its favor:

• You can't be talked out of the future payments. A single catastrophic decision costs you one year, not the whole prize.
• The escalator is real. Payments growing 5% annually offset the erosion of purchasing power in a way a flat annuity would not.
• The bond portfolio is not your problem. No sequence-of-returns risk, no market timing, no advisor fees eating the balance.

The counterweight, and it's a serious one: the payment stream depends on the issuing entity remaining solvent for 29 years, and you cannot easily undo the choice once made. Third parties will offer to buy out your remaining payments, and those offers are almost always priced badly against you.

The case for the lump sum

Control is the whole argument, and it's stronger than it first appears.

Investment flexibility. A 4.28% hurdle is not trivial, but it is also not exotic. A diversified portfolio held for 29 years has historically cleared that bar with room to spare. Nobody can promise it will, which is exactly why this is a risk-tolerance question and not a math question.

Estate flexibility. A lump sum can be moved into trusts, gifted, and structured while you're alive. Remaining annuity payments are an asset in your estate with far fewer moving parts available to you — an issue that matters a great deal if you're older when you win.

Large one-time needs. Buying out a business, clearing family debt, or funding a foundation is far simpler when the money exists than when it's a promise of $27 million a year.

Tax-rate risk runs both ways. A lump sum fixes your liability under today's brackets. An annuity exposes 29 more years of payments to whatever the top rate becomes. If you expect rates to rise, that's an argument for cash.

Whichever way you lean, the sequencing matters more than the choice itself. Our guide to the first 72 hours after a winning ticket covers what to do before you sign the back of the ticket, and most of it applies regardless of which payout you eventually pick.

How this connects to whether the ticket was worth buying

The cash-versus-annuity gap is also why expected-value math on lottery tickets is so much worse than the advertised jackpot suggests. Each assumption you layer on pushes the break-even jackpot higher:

Assumption (Powerball)	Break-even jackpot
Advertised annuity, no tax, no split	$491 million
Cash value (~50% of annuity), no tax	$982 million
Cash value + 37% federal tax	$1.56 billion
Cash + tax + split risk (~350M tickets)	$2.67 billion

The move from row one to row two is entirely the annuity-to-cash haircut. The move from row two to row three is federal tax. Together they roughly triple the jackpot needed before a $2 Powerball ticket is even nominally break-even — and the largest jackpot in the dataset, that $1.80 billion prize, still sits above the tax-adjusted line but well below the split-adjusted one. The full expected-value breakdown walks through where each of those numbers comes from.

Worth keeping in perspective: across the 406 Powerball draws in this dataset with jackpot data, 20 produced a jackpot winner, and the average winning jackpot was about $462.5 million — with the smallest at $20 million. For Mega Millions, 13 wins across 270 draws with jackpot data, averaging about $545.4 million. Billion-dollar prizes are the exception, not the norm; there are 16 jackpots at $1.00 billion or above in our top-jackpot list, and only 5 of those draws actually produced a winner. If you want the fuller picture, we tracked every billion-dollar jackpot and how often they really happen.

Before you choose: this is not tax advice

This article is general information, not tax, legal, or financial advice. Nothing here accounts for your state, your filing status, your existing assets, your family situation, or your estate plan — and every one of those changes the answer.

If you hold a winning ticket, retain a tax attorney and a fee-only fiduciary advisor before you claim, not after. The claiming decision is usually irreversible, deadlines vary by jurisdiction, and the structure you use to claim — individual, trust, or entity — can matter as much as the payout choice itself. The cost of good advice on a nine-figure prize rounds to nothing against the cost of getting it wrong.

One last framing point, because it's the honest one. Nothing about how you pick numbers, when you buy, or which payout you elect changes your probability of winning a jackpot. The draw is random and stays random. What these decisions genuinely control is how much you keep if the improbable happens, and how much you spend chasing it. Treat tickets as entertainment spending with a fixed budget, and run the numbers on any jackpot that catches your eye through the Payout Calculator so the headline figure never surprises you.

Frequently asked questions

Is the lump sum really half the advertised jackpot?

Historically, yes — the cash option has run around 50% of the advertised annuity. It isn't a fixed rule. The cash value is the money actually in the prize pool, and the ratio moves with prevailing interest rates: higher rates mean a smaller cash pile buys the same 30-year payment stream, pushing the percentage down. On the $1.80 billion Powerball jackpot of September 6, 2025, a 50% ratio implies roughly $900 million in cash before tax.

How much does a $1.80 billion jackpot actually pay after tax?

Taking the cash option at roughly $900 million, federal withholding of 24% removes about $216 million immediately, and the top marginal rate of 37% means roughly $117 million more is owed at filing — leaving about $567 million. Taking the annuity, the full $1.80 billion taxed at 37% leaves about $1.134 billion, but spread across 29 years. Both figures are federal only and exclude any state or local tax.

What return do I need to beat the lottery annuity?

At a cash option worth 50% of the advertised annuity, you'd need roughly 4.28% annually, pre-tax, to match the annuity's payment stream. If the cash ratio is 45%, the hurdle rises to about 5.02%; at 55% it falls to about 3.63%. Investment income tax pushes the real hurdle higher than these pre-tax figures suggest, so treat them as a floor rather than a target.

How are lottery annuity payments structured?

A jackpot annuity is 30 annual payments spread over 29 years — one immediately on claim, then 29 more annually. Each payment is about 5% larger than the previous one. On a $1.80 billion jackpot that means roughly $27.1 million in year one, about $42.0 million in year 10, and about $111.5 million in the final year. The escalator exists to offset inflation over the payout period.

Does taking the annuity reduce my tax bill?

Not through a lower rate. Each annual payment on a jackpot this size lands squarely in the top 37% bracket, so the effective rate is roughly the same either way. What the annuity does is spread the liability across 29 tax years, which exposes you to whatever future rates become — that's a risk, not a saving. The lump sum fixes your federal liability under today's brackets in a single year.

Can I change my mind after choosing a payout option?

Generally no. The election is made at claim time and is typically irreversible, and claim deadlines vary by jurisdiction. Companies will offer to buy out remaining annuity payments afterward, but those offers are usually priced heavily against the seller. This is exactly why you should have a tax attorney and a fiduciary advisor in place before you claim rather than after — the decision window is short and it doesn't reopen.
