How lottery cash value is calculated
When a jackpot is advertised at $1 billion, nobody receives $1 billion on day one. That headline number is the total of an annuity paid over three decades. The amount you could take at once, the cash value, is a lot smaller, before any tax. This guide explains where the two numbers come from and why the gap between them moves over time.
Two numbers for one prize
Powerball and Mega Millions both announce two figures before every draw:
- The advertised jackpot (also called the annuity jackpot). This is the sum of 30 payments made over 29 years. Mega Millions describes its annuity as one immediate payment followed by 29 annual payments, each 5% bigger than the one before. Powerball describes 30 graduated payments over 29 years.
- The cash value (also called the cash option or lump sum). Mega Millions describes it as a one-time payment equal to all the cash in the jackpot prize pool.
The cash value is the real money. The advertised jackpot is a projection of what that money becomes when it is paid slowly with interest.
Where the cash comes from
A share of every ticket sold goes into the jackpot prize pool. When nobody wins, the pool rolls over to the next draw and keeps growing as more tickets are sold. That pool, on draw night, is the cash value.
Because ticket sales rise sharply as the jackpot climbs, the cash pool grows faster in a long run of rollovers. That is why jackpots can jump by tens of millions of dollars between two draws late in a run.
How the advertised jackpot is built from the cash
To pay an annuity, the lottery would invest the cash and pay it out over 29 years. The advertised jackpot is the total of those payments. As the North Dakota Lottery put it in a 2022 news release, "The advertised Powerball jackpot is based on ticket sales and annuity interest rates."
In practice this means two things:
- The cash comes first. Sales fill the pool; the cash value is what is in it.
- Interest rates set the multiplier. The lottery estimates how much 30 growing payments that same cash could fund at current rates. Higher rates mean the cash can fund bigger payments, so the advertised jackpot is larger compared with the cash.
That is why the ratio of cash to advertised jackpot is not fixed. It moves with interest rates, so the cash share of a $1 billion jackpot in one year can differ from the cash share of a $1 billion jackpot a few years later.
A real example
For the Powerball draw of November 5, 2022, the North Dakota Lottery reported an advertised jackpot of $1.6 billion and an estimated cash option of $782.4 million. That is a ratio of about 49%:
| Figure | Amount |
|---|---|
| Advertised (annuity) jackpot | $1,600,000,000 |
| Estimated cash value | $782,400,000 |
| Cash as a share of advertised | ≈ 48.9% |
The same arithmetic works for any draw: divide the announced cash value by the advertised jackpot. Make sure both figures are for the same draw, because both change from draw to draw.
Why the numbers can change before the draw
Both figures are estimates based on expected sales and current rates, so they can be updated as a draw approaches. After a jackpot is won, the next draw starts again from the game's starting jackpot; for Mega Millions that starting jackpot became $50 million in April 2025, according to the North Dakota Lottery.
How we estimate cash value on this site
When the next draw's cash value is available in our data, the calculator uses it. When it is not, we estimate the cash value at about 43% of the advertised jackpot and label the result "estimated". That is a deliberately cautious figure: if the real ratio is higher, your real take-home is higher too. Our methodology page explains all the assumptions.
To use the announced figure yourself, open the calculator, choose "Other amount" and type both the advertised jackpot and the cash value.
Cash value is before tax
The cash value is a gross amount. When you claim it, the lottery withholds 24% for federal tax, plus state tax in many states. On a jackpot your federal rate is close to 37%, so the cash you finally keep is far lower again. In a state with no lottery tax, a $500 million cash value leaves roughly $315 million after the top federal rate. The every-state table shows the number for tonight's Powerball jackpot in each state.
Is cash or annuity better?
That depends on your age, your plans, how disciplined you are with money and what you think future tax rates will be. The annuity pays more in total, but over 29 years and with each payment taxed in the year you receive it. The cash gives you control now. We compare both in our lump sum vs annuity guide.
One rule to know: the choice can be final. The Texas Lottery, for example, says you choose the cash option on your playslip and may not change the payment option later. Rules differ by state, so check your state lottery before you buy or claim.
Common questions
Does the lottery keep the difference if I take the cash?
No. The cash value is all the money in the jackpot pool. The higher advertised figure only exists if the money is invested and paid out over time.
Why did the cash share change from one jackpot run to the next?
Mostly because interest rates changed. The same cash funds a bigger advertised annuity when rates are higher.
Is the cash value the same in every state?
Yes for the jackpot itself. Taxes and, in some states, payout-choice rules differ.
