Lottery Lump Sum vs. Annuity Breakeven Calculator
Example: Advertised jackpot: 50000000 $ · Cash value (% of jackpot, typically ~60%): 60 % · Federal tax rate on winnings: 37 % · State tax rate: 5 % · Annuity payment period: 29 years · Your required annual investment return: 7 %
| Breakeven return needed to beat the annuity | 0.04% |
| Lump sum after all taxes | $17,400,000 |
| Present value of annuity after taxes | $12,277,674 |
| Lump sum wins at your return rate? (1=yes) | 1 |
Worked example
A $50M jackpot: cash value $30M, after 37% federal and 5% state tax = $17.4M lump sum. The annuity pays roughly $1.725M/year after the same tax rate; at a 7% discount rate, its present value is $21.2M. You need to earn more than ~4.7% annually on the lump sum to come out ahead — a breakeven most disciplined investors can clear, but far from automatic.
Frequently asked questions
Do Powerball and Mega Millions offer the same lump-sum percentage?
Both typically offer a cash value of roughly 50–65% of the advertised jackpot, depending on current interest rates. When rates are high, the cash value percentage tends to rise because the annuity stream is discounted more steeply.
Does the annuity protect against spending it all at once?
Yes — the annuity is the built-in behavioral protection. Research on lottery winners shows most who take the lump sum are broke within 5 years; the annuity forces discipline. This calculator gives you the math, but the behavioral factor varies by individual.
Are lottery winnings taxed in the year received?
Yes — lottery winnings are ordinary income in the year received. The IRS withholds 24% upfront, but winners at the $50M level owe 37% federal. The gap creates a large April tax bill. State taxes vary; nine states have no lottery income tax.
Can I invest the annuity payments instead of taking the lump sum?
You can invest each annual annuity payment as you receive it, but you lose the compounding benefit of deploying the full lump sum on day one. The breakeven rate this calculator shows is the hurdle for the lump-sum path — it must exceed the implied return baked into the annuity discount.
