The headline jackpot you see advertised is the annuity value — and for Powerball and Mega Millions it is not paid in equal yearly checks, and it is not indexed to inflation. It is paid as 30 graduated payments that grow by a fixed 5% each year. Here is how the 30-year annuity actually works, and how it compares to the lump sum most winners take.
What the 30-year annuity really is
Choose the annuity and you receive the full advertised jackpot spread over 30 payments: one immediate payment, then 29 more once a year. The catch that trips most people up is that the payments are not equal. Each annual payment is 5% larger than the one before it, a schedule the lotteries publish openly. The first payment is the smallest and the 30th is by far the largest.
So a “$300 million” annuity does not pay $10 million a year (300 ÷ 30). It starts well below that and climbs each year, with the total across all 30 payments adding up to the advertised $300 million.
It is graduated, not inflation-adjusted
This is the detail that’s widely misreported. The 5% annual increase is a fixed step written into the payout schedule — it is not tied to the Consumer Price Index or any measure of actual inflation. In years when real inflation runs above 5%, your rising payment can still lose purchasing power; in low-inflation years it gains. Do not confuse a guaranteed 5% graduation with a cost-of-living adjustment. They are different things.
Annuity vs. the cash (lump-sum) option
Almost every winner takes the other option: the cash value. This is the actual amount sitting in the prize pool right now — the sum the lottery would otherwise invest in bonds to fund those 30 growing payments. It is typically around half of the advertised annuity. If a jackpot is advertised at $300 million, the cash option is often near $140–160 million.
- Annuity: full advertised amount, but locked into a 30-year, 5%-graduated schedule you can’t accelerate.
- Cash: roughly half the headline, paid at once, yours to invest, spend, or lose immediately.
The annuity is effectively a guaranteed ~5% annual return with zero market risk. Whether that beats taking the cash and investing it yourself depends on your discipline, your time horizon, and future tax rates — not on a simple “bigger number wins.” See our companion guide on cash value vs. the advertised jackpot.
How taxes hit each option
Both options are taxed as ordinary income. A large prize has 24% withheld up front, but a jackpot pushes you into the top federal bracket of 37%, so you settle the difference at tax time — plus any state tax. The annuity’s one real tax edge is that it spreads the income across 30 years, which can keep more of it below the very top rate; the cash option is taxed all at once in a single year. The full breakdown is in net lottery winnings after taxes.
So which should you take?
There’s no universal answer, but be honest about the trade-off: the annuity protects you from your own worst spending impulses and hands you a risk-free 5% ladder; the cash gives you control and flexibility but demands discipline. What it is not is a choice between “equal safe payments” and a lump sum — the payments grow, and neither option is indexed to inflation. And remember none of this changes the thing that matters most: whether the ticket was ever worth buying.
The honest takeaway
- The 30-year annuity pays the full advertised jackpot as 30 payments that grow 5% a year — not equal installments.
- The 5% step is fixed, not an inflation adjustment; high inflation can still erode it.
- The cash option is roughly half the headline but paid immediately; most winners take it.
- Both are taxed as ordinary income (up to 37% federal); the annuity just spreads it out.
