Lump sum or annuity: what you are actually choosing
Everyone runs the fantasy budget between buying the ticket and checking the numbers. This page is for that moment, done honestly. A jackpot winner faces exactly one decision with real money on the line, and it is this one, so it deserves real arithmetic instead of a gut call.
The first thing to understand is that the advertised jackpot is not a pile of money. It is the sum of 30 annuity checks: one now, then 29 more, each 5% larger than the last, so the final check is about four times the first. The cash option is the smaller pool that actually exists, priced as the amount the lottery would need today, invested in US Treasury securities, to fund all 30 checks. Lately that pool runs a little over 43% of the billboard number. Neither figure is what you keep: federal tax takes 24% at the claim window as withholding and roughly 37% in truth at filing, and most states take a cut on top, from nothing at all to 14.776% in New York City.
So the honest comparison, and the one most payout tables skip, has three stages: tax both options fully, then invest both (the lump sum from day one, each annuity check as it arrives), then compare what they are worth in the year the final check would have landed. That comparison collapses to a single number: the return at which the two paths tie. Earn more than it and the cash wins; earn less and the checks win.
The formula
Lump sum value = (Cash − taxes) × (1 + r)29
Annuity value = Σ (checkn − taxes) × (1 + r)29 − n
Jackpot is the advertised figure and Cash is the lump-sum option. Each of the 30 checks is 5% larger than the one before, and n runs from 0 (the first check) to 29 (the last). r is your yearly investment return after investment taxes and fees. Federal tax is computed on each amount from the 2026 brackets, the same table our income tax calculator uses; state tax applies your state's top 2026 rate. The break-even return is the r that makes the two values equal.
Worked example
The August 2026 Powerball: a $905,000,000 advertised jackpot with a $391,900,000 cash value, won by a single filer in a state with no income tax, investing at 5% a year after tax.
Lump sum: the claim window withholds 24%, which is $94,056,000. But the real federal bill at 2026 rates is $144,953,000, so another $50,897,000 is due at filing: the April surprise. The winner banks $246,947,000.
Annuity: the first check is $13,621,549, and by year 30 the checks have grown to $56,068,142. After federal tax on each check, the winner collects $571,649,992 across three decades, well over twice the lump sum in spendable dollars.
Invested at 5%: the lump sum grows to $1,016,467,336 by year 30. The checks, each invested on arrival, reach $1,063,009,803. The annuity finishes about $46.5 million ahead.
The break-even: 5.33% a year after tax. At 6%, the picture flips: the lump sum reaches $1,338,054,635 against the annuity's $1,223,865,753 and wins by about $114 million. The entire decision lives inside that narrow band of expected return.
Is there a jackpot size where the answer flips?
This is the question people actually argue about, and the answer surprises most of them: there is no size at which the lump sum becomes automatically right. The pull runs the other way. The smaller the prize, the stronger the annuity's case, because of a second advantage that has nothing to do with investment returns: bracket spreading. One giant payment stacks nearly everything into the 37% federal bracket. Thirty smaller checks each start filling the brackets from the bottom again, every year, and on modest prizes that saves serious tax. At the same 43.3% cash ratio:
| Advertised prize | Break-even return | Federal tax saved by spreading |
|---|---|---|
| $2,000,000 | 7.54% | 20.7 points (31.2% vs 10.5% average rate) |
| $10,000,000 | 6.79% | 11.4 points |
| $20,000,000 | 6.21% | 6.6 points |
| $100,000,000 | 5.50% | 1.4 points |
| $905,000,000 | 5.33% | 0.2 points (bracket spreading is dead) |
At true jackpot scale the brackets stop mattering, since everything above $640,600 is taxed at 37% either way, and the choice becomes purely your expected return against the break-even. Your state does not move the choice either: a flat bite scales both options equally, so New York's 10.9% changes the size of every check but barely shifts the break-even (5.332% there against 5.328% with no state tax). Your state changes the check, not the choice.
The honest case for each
The case for the lump sum is control. A diversified portfolio has historically returned more than 5.33% after tax over 30-year stretches, though never with a guarantee, and money in hand today offers estate flexibility the annuity cannot match. The case for the annuity is that it is a guaranteed 5.33% after-tax return on hundreds of millions of dollars, a quote no private bank will write, and it is the only option with built-in protection from the year-one version of you, the one every cautionary winner story is about. On that subject, honesty cuts both ways: the famous claim that 70% of lottery winners go broke is folklore, publicly disavowed in 2018 by the National Endowment for Financial Education, the organization it was attributed to. What is documented is that outcomes vary enormously, and the annuity is the one choice with a floor under it.
One more thing the choice is not: a reason to buy tickets. The odds of the jackpot are 1 in 292,201,338, and even at $905 million a $2 ticket has negative expected value once taxes, the cash discount and the chance of splitting the prize are counted.
