π° Lottery Annuity Calculator
Present value of graduated lottery annuity payments.
Estimated lump sum (present value)
Estimates for planning only, not financial advice.
A lottery jackpot is a payment schedule wearing a big number as a costume. The advertised $100 million is 30 graduated annual payments totaling $100 million, not $100 million today. Discounted at 4 percent, those payments are worth about $50 million in present value, which is why the cash option sits near half the headline. This calculator values any jackpot's annuity stream at your discount rate and shows each payment.
The annuity-versus-cash choice is really a question about who you are. The math favors cash for a disciplined investor; the psychology favors the annuity for everyone else. Lottery history is a graveyard of lump sums spent in five years, which is worth weighing alongside the spreadsheet.
How to Use This Calculator
Enter the advertised jackpot in millions, the number of payment years, the annual growth rate of payments, and the discount rate. The calculator shows the present value, the first and last payments, and the cash value as a share of the jackpot.
Enter the advertised jackpot and payment years. US games default to 30 years.
Enter the payment growth rate, 5 percent for Mega Millions and Powerball, and your discount rate.
Read the present value. For the tax bite on either option, our lottery tax calculator estimates federal and state taxes.
The Formula
The first-payment formula spreads the jackpot total across graduated payments growing at rate g. Each payment is then discounted at rate d. When the discount rate exceeds the growth rate, later payments shrink in present value despite growing in nominal dollars, which is why the total lands near half the headline.
Annuity Versus Lump Sum
| Factor | Annuity | Lump sum |
|---|---|---|
| Total received | Full advertised jackpot | ~45 to 55% of jackpot |
| Tax timing | Spread over 30 years | All at once, top bracket |
| Control | None after claiming | Full, immediately |
| Overspending risk | Structurally limited | Historically high |
| Investment upside | Fixed schedule | Unlimited |
The tax row deserves emphasis: spreading $100 million over 30 years keeps many payments out of the top federal bracket, while the lump sum lands entirely in it. That tax smoothing is the annuity's quiet financial edge, worth real money even before behavior enters the picture.
Worked Example
With the defaults: $100 million jackpot, 30 years, 5 percent payment growth, 4 percent discount rate. The first payment is 100,000,000 x 0.05 / (1.05^30 - 1) = $1,505,144. The final payment grows to 1,505,144 x 1.05^29 = $6,195,375. Discounting all 30 payments at 4 percent gives a present value of $50,051,367, or 50.1 percent of the advertised jackpot. Raise the discount rate to 6 percent and the present value falls to roughly $37 million.
The Decision Framework
Take the annuity if you want forced discipline, tax smoothing, and zero investment decisions. Take the lump sum if you will genuinely invest it, have estate planning needs the annuity cannot serve, or distrust your ability to leave future payments alone, since annuity streams can be sold at terrible prices. Either way, hire a tax attorney and a fiduciary advisor before claiming, assemble them before the ticket is even validated, and tell almost no one.
My rule: the lump sum is the better financial instrument and the worse human one. Choose based on an honest assessment of which risk is bigger for you: market risk you can manage, or yourself, which most winners historically could not.
The Annuity Versus Lump Sum Decision
Almost every winner takes the lump sum, and the math usually agrees. The annuity's implied return equals the discount rate used to price it, recently around 4 to 5 percent, which a diversified portfolio has historically beaten. The lump sum also avoids the risk that tax rates rise over the 30-year payout, and it gives you control: you can buy your own annuity later if you want guaranteed income.
The annuity's case is behavioral, not mathematical. Thirty years of guaranteed growing payments protect winners from themselves, and lottery history is full of lump-sum winners who spent it all. A middle path exists: take the lump sum, then immediately annuitize a portion and invest the rest. You keep the higher expected return on most of the money while the annuity portion guarantees you can never go broke. Our lottery tax calculator shows what either choice nets after taxes.
Protecting the Annuity Stream
Annuity payments are an asset, which means creditors and ex-spouses may come after them. Winners have sold future payments to factoring companies at brutal discounts, often 50 cents on the dollar or worse, when cash got tight. If you take the annuity, treat the stream as untouchable: build the emergency fund first so the payments never need selling.

How does a lottery annuity work?
Instead of one lump sum, the lottery invests the cash value in government securities and pays you graduated annual installments, usually over 29 or 30 years. Mega Millions and Powerball payments rise about 5 percent each year to offset inflation. The advertised jackpot is the sum of all those future payments, not money sitting in a vault.
Why is the cash option so much smaller than the jackpot?
Because of the time value of money. A $100 million jackpot paid over 30 years is worth far less today once future payments are discounted to present value. The cash option, typically 45 to 55 percent of the advertised jackpot depending on interest rates, is roughly what the lottery would invest today to fund the annuity.
How is the lottery annuity payment schedule structured?
The first payment arrives soon after claiming, then one payment a year for the remaining term, each about 5 percent larger than the last. On a $100 million jackpot that means roughly $1.5 million first and $6.2 million last. The growth is designed so later payments keep their purchasing power.
Annuity or lump sum: which is better?
Financially, the lump sum usually wins if you invest it at a reasonable return, because you control the money for the full 30 years. Behaviorally, the annuity protects winners from themselves: most big winners who take cash dissipate it. The honest answer depends on whether you trust your future self with $50 million at once.
How are lottery winnings taxed?
Federal tax hits immediately at 24 percent withholding, with the balance up to the 37 percent top bracket due at filing. State taxes add 0 to 13 percent more. Annuity payments are taxed year by year as received, which can keep you in lower brackets, while the lump sum is taxed all at once at the top rate.
What discount rate should I use?
Use a rate reflecting what the money could earn: 4 to 6 percent for a conservative bond-like return, higher if you would invest aggressively. The lottery itself uses prevailing government bond yields. A higher discount rate shrinks the present value and makes the cash option look relatively better.
Can I sell my lottery annuity payments?
Yes, through structured settlement buyers, but at a steep discount, often 10 to 30 percent below present value, plus fees. Courts must approve the sale in many states. It is almost always the worst way to convert an annuity to cash, which is another argument for choosing carefully at claim time.
What happens to annuity payments if the winner dies?
They continue to the winner's estate or named beneficiaries for the remaining term. The annuity is an asset of the estate and may face estate tax. Winners should set up beneficiary designations and trusts before claiming, not after.
Do interest rates change the cash option?
Yes, inversely. When rates rise, the lottery needs less cash today to fund the same future payments, so the cash option shrinks as a share of the jackpot. When rates fall, the cash option grows. That is why the cash percentage drifts between roughly 45 and 55 percent over the years.
Is the advertised jackpot guaranteed?
The annuity total is backed by the lottery's invested securities, effectively government-guaranteed. But the number assumes you live to collect all 30 payments or pass them to heirs, and it ignores taxes and inflation. The only guaranteed spendable number is the after-tax present value.
