Quick answer: The advertised jackpot is the 30-year annuity, not the money you receive. Across the last 12 Powerball and Mega Millions drawings in our database, the cash value averaged 43% of the advertised jackpot — and federal withholding takes 24% of that up front, with more due at filing. A "$100 million" jackpot is realistically about $27 million in hand.
What is a jackpot analysis?
It is the arithmetic between the billboard number and your bank balance. Three separate reductions apply, in this order:
- Annuity → cash. The advertised figure is what the lottery would pay over 30 graduated annual payments. Take the lump sum instead and you get the present-day cost of funding that annuity — currently around 43%.
- Federal withholding. 24% is withheld immediately on the cash amount.
- The rest of the federal bill, plus state tax. A jackpot lands you in the 37% top bracket, so the 24% withheld is a down payment, not the total. State tax then ranges from 0% to over 10%.
What the cash value actually is: real numbers
Here is the annuity-to-cash ratio from every recent drawing in our data, rather than a rule of thumb:
| Game | Advertised jackpot | Cash value | Cash as % of advertised |
|---|---|---|---|
| Powerball | $1 billion | $433.1 million | 43.3% |
| Mega Millions | $800 million | $344.2 million | 43.0% |
| Powerball | $173 million | $74.6 million | 43.1% |
| Mega Millions | $177 million | $76.3 million | 43.1% |
| Powerball | $20 million (reset) | $8.7 million | 43.5% |
The ratio is remarkably stable — 43.2% average for Powerball, 42.8% for Mega Millions across the last dozen draws of each — because it is driven by prevailing interest rates, not jackpot size. When rates rise the cash percentage rises with them; the 60% figures quoted in older articles date from a very different rate environment.
So what is a jackpot really worth?
Work an advertised $100 million Powerball jackpot all the way through, for a single winner taking cash:
| Step | Amount |
|---|---|
| Advertised jackpot (annuity) | $100,000,000 |
| Cash value at ~43% | $43,000,000 |
| Less 24% federal withholding | −$10,320,000 |
| Less remaining federal tax to the 37% bracket | −$5,590,000 |
| Net, in a state with no lottery tax | ≈ $27,090,000 |
| Net in a high-tax state (e.g. ~10%) | ≈ $22,790,000 |
Roughly 27 cents on the advertised dollar in a tax-free state, closer to 23 in a high-tax one. Our federal and state tax breakdown covers the filing mechanics, and lump sum vs annuity covers the choice itself.
Mega Millions winning breakdown: the full prize chart
"Jackpot analysis" usually means the top prize, but eight other tiers pay out on every draw. These are the current Mega Millions base amounts, which already include the built-in 2× minimum multiplier:
| Match | Mega Millions | Powerball |
|---|---|---|
| 5 + bonus ball | Jackpot | Jackpot |
| 5 | $2,000,000 | $1,000,000 |
| 4 + bonus ball | $20,000 | $50,000 |
| 4 | $1,000 | $100 |
| 3 + bonus ball | $400 | $100 |
| 3 | $20 | $7 |
| 2 + bonus ball | $20 | $7 |
| 1 + bonus ball | $14 | $4 |
| Bonus ball only | $10 | $4 |
Second-tier prizes are cash and paid in full — no annuity, no 30-year wait — but the same federal withholding applies above $5,000.
What is a "lotto division"?
"Division" is the Australian, New Zealand and UK term for what American lotteries call a prize tier. Division 1 is the jackpot, Division 2 the next tier down, and so on. US games number nothing — they describe the match instead, as "5 + Powerball" or "4 of 5". If a site tells you a ticket won "Division 3," translate it as the third prize tier of that game.
One real difference lurks behind the vocabulary: many overseas games are pari-mutuel, meaning each division shares a percentage of the pool and prizes vary every draw. Most US non-jackpot prizes are fixed amounts instead — with California a notable exception, where every tier is pari-mutuel.
Quick answers
What is the cash value of a lottery jackpot?
The lump sum a winner receives instead of the 30-year annuity. In recent Powerball and Mega Millions draws it has run at about 43% of the advertised jackpot.
How much of a $100 million jackpot do you actually keep?
About $27 million taking the cash option in a state with no lottery tax, after the annuity-to-cash reduction and federal tax at the top rate. Less in states that tax winnings.
Why is the cash option so much lower than the advertised jackpot?
Because the advertised figure is the total of 30 annual payments that rise 5% each year. The cash option is what it costs today to fund those payments, which is far less than their headline sum.
What does Division 1 mean in the lottery?
It is the non-US term for the top prize tier — the jackpot. American games describe tiers by the match instead, such as "5 + Powerball".
Bottom line
Advertised jackpot × 43% = cash value. Cash value × roughly 63% = what you keep federally, before state tax. Track the live figures for both games on our Powerball jackpot history and Mega Millions jackpot history pages, which chart every rollover and reset.
