- How does a lottery annuity actually pay out?
- Powerball and Mega Millions pay the advertised jackpot as 30 graduated payments: one when you claim, then one a year for 29 more years. Each payment is 5% larger than the last, and all 30 together add up to the advertised number. On a $100,000,000 jackpot the first gross payment is $1,505,143.51 and the thirtieth is $6,195,374.77. That growth is the part people miss — the annuity is not the jackpot divided by 30.
- What is the break-even return, and why does it matter more than the totals?
- It's the annual after-tax return at which investing the cash option leaves you exactly where the annuity would. On a $100,000,000 Florida jackpot with a 60% cash option, the break-even is 3.19%. Earn more than that and the cash wins; earn less and the annuity wins. Every other calculator compares $64,289,392 of annuity spread over 30 years against $37,842,980 of cash today and lets you conclude the bigger number is better. It isn't automatically — $64M arriving slowly over three decades is worth about $29M today at a 5% return. The break-even rate is the one number that settles the argument.
- Why is the annuity's total after-tax number higher than the lump sum's?
- Two reasons. The cash option is only about 60% of the advertised jackpot to begin with, and the annuity spreads income across 30 tax years instead of one. Spreading helps less than you'd hope: every annual payment on a nine-figure jackpot still lands in the 37% top federal bracket, so the effective rate barely moves. The bulk of the gap is simply that you're comparing 100% of the jackpot against 60% of it.
- Which state rate does this use — where I live or where I bought the ticket?
- Where you live. The calculator applies your state of residence's 2025 lottery withholding rate for residents. In real life both can matter: some states withhold on prizes won there by non-residents, and your home state may credit or top up that amount. If you bought the ticket in a different state from the one you live in, treat the result as an estimate and get a tax professional involved before you claim.
- Why does the first payment not get discounted?
- Because it arrives when you claim, not a year later. Present value discounts each payment by how long you wait for it, so year 1 sits at t = 0 and isn't discounted at all, year 2 is discounted one year, and so on through year 30. Getting this wrong shifts the whole present value by a full year — roughly 3% to 5% — which is enough to move the break-even rate and flip the verdict on a close call.
- Is the break-even rate something I can realistically earn?
- That's the whole question, and it's harder than it looks because the break-even is an after-tax return. A 3.19% after-tax return means clearing roughly 4% to 5% pre-tax once federal and state tax on your investment gains come out, depending on the account and the state. Long-run stock market returns have historically beaten that, but not every year, and not without the discipline to leave a nine-figure balance alone. The annuity's real advantage isn't the rate — it's that it can't be spent all at once.
- What happens to the annuity if the winner dies before year 30?
- The remaining payments go to the winner's estate; they aren't forfeited. Most state lotteries let the estate continue receiving the schedule, and some allow a request to accelerate the balance into a lump sum so the estate can settle. Estate tax is calculated on the value of those remaining payments, which is a real planning problem the calculator doesn't model. It's one of the strongest arguments for taking cash if you're older, and one of the reasons every winner needs an estate attorney before claiming.
- How accurate are these numbers?
- The arithmetic is exact; the assumptions are the soft part. The calculator uses 2025 federal single-filer brackets held flat for all 30 years, and 2025 resident state withholding rates. Neither will hold for three decades — brackets are indexed to inflation every year, rates get legislated up and down, and a married-filing-jointly return changes the math. The break-even rate is directionally right, not a forecast. Treat it as the shape of the decision, not the final answer.
- Why does the calculator show more than 50% as ">50%"?
- Because past that point the break-even stops being a useful number. If you set the cash option very low, the lump sum gets so small that no plausible return lets it catch the annuity, and the solver would report something like 240% — technically correct, practically meaningless. Showing ">50%" says the honest thing: at any return you could actually earn, the annuity wins.
- How is this different from the Lottery Tax Calculator?
- The Lottery Tax Calculator answers "what do I keep?" — it compares the lump sum and the annuity after tax, in nominal dollars, and tucks the payment schedule behind a toggle. This one answers "which payout wins, and at what return?" The 30-row schedule is the point here, it's visible from the start, and every number is run through present value so a dollar in 2056 isn't counted the same as a dollar today. Use that one for the tax bill, this one for the decision.
