π° Mega Millions Payout Calculator
Annuity versus cash option, after taxes.
Net cash option after tax
Estimates for planning only, not financial advice.
A Mega Millions jackpot offers two doors: 30 graduated payments totaling the advertised amount, or a cash lump sum near half of it. On a $500 million jackpot with a 48 percent cash option, the cash is $240 million pre-tax, about $139.2 million after 37 percent federal and 5 percent state tax. The annuity's $500 million, taxed year by year, nets roughly $290 million in simplified terms. This calculator compares both paths after tax from your jackpot, cash percentage, and state rate.
The annuity's edge is tax smoothing: spreading income across 30 years keeps much of it out of the top bracket. The cash option's edge is control and investment upside. The right door depends on the numbers and on the person walking through.
How to Use This Calculator
Enter the advertised jackpot in millions, the cash option as a percentage of the jackpot, and your state tax rate. The calculator shows the pre-tax cash option, taxes, net cash, and the simplified after-tax annuity total.
Enter the advertised jackpot and the actual cash option percentage for the drawing.
Enter your state tax rate on winnings, 0 for exempt states.
Compare net cash against the annuity total. For the detailed annuity valuation, our lottery annuity calculator discounts each payment.
The Two Options
The annuity simplification overstates its tax a bit, since spreading income lowers the effective rate below 37 percent in many years, which only strengthens the annuity's case. The honest comparison also needs a discount rate on the annuity stream and an assumed investment return on the cash, which the linked annuity calculator handles payment by payment.
After-Tax Comparison
| Cash option | Annuity | |
|---|---|---|
| Pre-tax amount | $240.0M (48%) | $500.0M total |
| Federal tax (37%) | $88.8M | Spread, lower effective |
| State tax (5%) | $12.0M | Spread across years |
| Simplified net | $139.2M | ~$290.0M |
The annuity's simplified net is more than double the cash net, which looks decisive until investment returns enter. If the $139.2 million net cash compounds at 6 percent for 30 years, it grows past $790 million, dwarfing the annuity. The real question is behavioral: will the cash actually stay invested? For most winners in history, the answer was no. For tax detail on either path, our lottery tax calculator breaks down any prize.
Worked Example
With the defaults: $500 million jackpot, 48 percent cash option, 5 percent state tax. The cash option is 500,000,000 x 0.48 = $240,000,000. Federal tax at 37 percent is $88,800,000 and state tax is $12,000,000, for $100,800,000 total tax. Net cash is $139,200,000. The simplified after-tax annuity is 500,000,000 x (1 - 0.37 - 0.05) = $290,000,000, giving the annuity a $150,800,000 simplified edge before investment returns are considered.
Claiming Checklist
Sign and secure the ticket immediately, then go quiet. Assemble a tax attorney, CPA, and fiduciary advisor before contacting the lottery. Model both options with your actual state taxes and a realistic investment return assumption. Set up trusts or claiming entities where your state allows, decide on anonymity options, and plan charitable giving before the money lands, when generosity is a strategy rather than a reaction.
My rule: decide with a spreadsheet, then stress-test with your history. If you have ever blown a windfall, take the annuity and let the schedule protect you from yourself. If you are a disciplined investor with advisors in place, the cash option's upside is real. Most people overestimate which category they are in.
Claiming Strategy for Big Winners
You usually have 60 days to a year to claim, and rushing is the classic error. Use the time to assemble a team: a tax attorney, a CPA experienced with windfalls, and an estate planner. In many states you can claim through a blind trust, which keeps your name out of the press and gives you a layer of privacy that money cannot otherwise buy. Sign the ticket, photograph it, and store it securely; a lost unsigned ticket is a disaster.
Decide the annuity-versus-cash question with math, not fear. The annuity's implied return is the discount rate used to price it, and a diversified portfolio has historically beaten it, but the annuity protects against the well-documented tendency of winners to spend everything. Either way, set aside the full tax bill before spending a dollar, make gifts deliberately with an eye on the lifetime exemption, and tell almost no one. For the present-value math of the annuity stream, our lottery annuity calculator discounts each payment.
Why Jackpots Keep Growing
Mega Millions jackpots roll over because the odds, about 1 in 302.6 million, make unwon drawings the norm. Each rollover adds ticket revenue to the prize pool, and media coverage of a billion-dollar jackpot drives a feedback loop of sales. The advertised annuity value assumes 30 growing payments; the cash value reflects what the ticket sales actually funded.

How does the Mega Millions payout work?
Winners choose between 30 graduated annual payments totaling the advertised jackpot, rising 5 percent per year, or a one-time cash payment of roughly 45 to 55 percent of the jackpot. The cash value is what the lottery would invest in government securities today to fund the annuity. Federal tax up to 37 percent and state tax apply to either choice.
What is the cash option percentage?
It floats with interest rates, typically 45 to 55 percent of the advertised jackpot. When rates rise, the lottery needs less cash today to fund future payments, so the percentage falls. Check the actual cash value for the specific drawing, since the advertised jackpot alone does not determine it.
How much does a $500 million jackpot pay after taxes?
Roughly: a 48 percent cash option is $240 million pre-tax. Federal tax at 37 percent takes $88.8 million and 5 percent state tax takes $12 million, leaving about $139.2 million. The annuity's $500 million spread over 30 years faces lower effective rates year by year, a key part of the comparison.
Is the annuity or cash option better?
After tax, the annuity usually delivers more total dollars because spreading income avoids stacking everything into the top bracket at once. But the cash option gives control: invested well, it can beat the annuity's total. The decision blends math with self-knowledge about spending discipline.
How are Mega Millions winnings taxed?
As ordinary income in the year received. The lottery withholds 24 percent federally at payout, but the top 37 percent rate applies to nearly all of a jackpot, leaving a large balance due. State taxes add 0 to about 13 percent. Annuity payments are taxed annually as received.
Can the annuity payments be inherited?
Yes. If the winner dies, remaining payments go to the estate or designated beneficiaries. The annuity is an estate asset potentially subject to estate tax. Proper beneficiary designations and trusts should be set up before claiming.
What is the 5 percent annual increase in the annuity?
Each yearly payment grows about 5 percent over the prior one, so later payments are much larger: on a $500 million jackpot the first payment is roughly $7.5 million and the last about $31 million. The growth offsets inflation across the 30-year schedule.
Do I have to choose immediately?
Winners get a limited window, usually 60 days from claiming, to elect cash or annuity, and the choice is irrevocable. Use the time to model both options after tax with advisors rather than deciding at the counter.
Which states tax lottery winnings the most?
New York and New Jersey approach 11 percent at the top, while California, Texas, Florida, and several others levy no state tax on winnings. Where you claim and where you reside can both matter, so the state line on the calculator swings the answer by tens of millions on big jackpots.
Should winners go public?
Most advisors say no. A handful of states allow anonymous claims; elsewhere, winners use trusts or legal entities where permitted to shield their identity. Publicity brings scams, lawsuits, and endless requests, and it cannot be undone once the press conference happens.
