    Introduction

    The advertised Mega Millions jackpot is not the money you take home. Taxes and your payout choice cut that number down by a lot. This Mega Millions payout calculator shows what you would really keep after taxes.

    Type in the jackpot amount, pick how many winners share it, and choose your state. The calculator then shows both payout options side by side:

    • Lump sum (cash option): one payment now, worth about 50% of the advertised jackpot.
    • Annuity: 30 yearly payments that grow 5% each year and add up to the full jackpot.

    You will see the federal tax, the state and local tax, and your net payout for each choice. You can view federal tax as the 24% withheld at payout, or the 37% top rate most jackpot winners really owe. You can also add the cost of your tickets ($5 each) and see a year-by-year payment schedule, charts, and the value of the annuity in today's dollars. If you want a simpler view of just the tax side, the Lottery Tax Calculator covers any game, and the Mega Millions Calculator handles the basic prize math.

    How to use our Mega Millions Payout Calculator

    Enter the jackpot size, how many winners share it, your state, and your ticket cost. The calculator shows your cash lump sum, your 30-year annuity payments, the federal and state taxes taken out, and the net money you keep.

    Advertised Jackpot Amount: Type the jackpot you see on the news or at megamillions.com. Commas are added for you.

    Sample Jackpot Quick-Fill: Click this button to load a sample $525,000,000 jackpot if you just want to test the tool.

    Number of Winners Splitting the Jackpot: Pick how many tickets match all the numbers. The prize is split evenly before taxes, so picking 2 cuts your share in half.

    State / Jurisdiction: Choose where you live and claim the prize. The tax rate for each state is shown next to its name, and some states take 0%. Our State Tax Calculator goes deeper on how your state treats other income too.

    Federal Tax Display Mode: Pick "Withholding Only (24%)" to see what the IRS holds back at payout. Pick "Final Liability (37%)" to see the full amount a jackpot winner likely owes at tax time. The Tax Bracket Calculator shows how a windfall pushes you into the top bracket.

    Number of Tickets Purchased: Enter how many tickets you bought at $5.00 each. The tool subtracts that cost to show your true net payout. Leave it at 0 to skip this step.

    Megaplier Add-On: This box is turned off because the Megaplier ended in April 2025. No action is needed.

    Calculate and Reset buttons: Results update as you type, but you can click Calculate to refresh right away or Reset to start over with the default values.

    Lump Sum and Annuity tabs: Switch between the two tabs to compare the one-time cash option and the 30 yearly payments. Open the year-by-year schedule to see each payment grow 5% per year. For a side-by-side of both routes across any lottery game, try the Lottery Payout Calculator.

    Mega Millions Payout: What You Really Take Home

    When you win a Mega Millions jackpot, you never get the big number you see on the sign. That number is the annuity value. It is the total of 30 yearly payments. If you want your money right away, you get the cash option, which is about half of the advertised jackpot. Then taxes come out of whatever you pick.

    Lump Sum vs. Annuity

    • Lump sum (cash option): One payment, right now, worth roughly 50% of the advertised jackpot. You control the money and can invest it, but you also risk spending or losing it. Run the number through an Investment Calculator or a Compound Interest Calculator to see what patient investing could do.
    • Annuity: 30 payments over 29 years. The first payment is the smallest. Each payment after that grows 5% to help keep up with rising prices. You get the full jackpot amount, but you must wait for most of it. The Lottery Annuity Calculator and the general Annuity Payout Calculator break the schedule down further.

    How Taxes Cut Your Prize

    The IRS takes 24% right away as federal withholding. But a jackpot pushes you into the top federal bracket of 37%, so you usually owe about 13% more when you file your tax return. Planning for that extra bill matters, and an Effective Tax Rate Calculator or the broader Income Tax Calculator helps you size it up.

    Next comes state and local tax. Rates change a lot by place. New York City winners can lose close to 15% to state and city tax. States like Florida, Texas, Tennessee, Washington, and South Dakota take nothing. California and Delaware do not tax lottery winnings either. Where you buy your ticket and where you live both matter — see the NYC Tax Calculator, California Tax Calculator, or Florida Tax Calculator for the local picture.

    Splitting the Jackpot

    If more than one ticket matches all six numbers, the jackpot is split evenly before any taxes. Each winner then chooses cash or annuity on their own share.

    Today's Dollars vs. Future Dollars

    Money you get in year 25 buys less than money you get today because prices rise. That is why the annuity's total looks bigger but is worth less than it seems. Using about 2.5% yearly inflation, the annuity's real value drops closer to the lump sum. The annuity's 5% growth helps, but it does not erase the gap. Test other inflation rates with the Inflation Calculator, or discount the payment stream yourself using the Present Value Calculator and NPV Calculator.

    Ticket Facts You Should Know

    • A Mega Millions ticket costs $5.00 after the April 2025 game change.
    • The Megaplier add-on was removed in that same change. Every ticket now has a built-in multiplier for non-jackpot prizes.
    • Jackpot odds are about 1 in 290 million. The Probability Calculator and Combination Calculator show where that figure comes from.
    • The cash option percentage moves with interest rates, so the real cash value on your win may be a bit above or below 50%.

    Advertised jackpots and cash values change with every drawing. Always check the official amount at megamillions.com, and talk to a tax pro or financial advisor before you claim a big prize.

The Powerball Payout Calculator and Powerball Tax Calculator run the same math for Powerball, and once the money lands, a Net Worth Calculator or Retirement Calculator helps you plan what comes next.

    Frequently asked questions

    Why is the cash option only about half of the advertised jackpot?

    The advertised jackpot is the total of 30 payments spread over 29 years. The lottery only has the cash sitting in the prize pool today, which is about half that amount. The rest of the annuity total comes from interest the money earns while it is invested.

    The calculator uses a 50% cash factor. The real percentage moves with interest rates, so your official cash value may be a little higher or lower.

    Do I pay state tax where I bought the ticket or where I live?

    Usually both matter. The state where you bought the ticket withholds its tax first. Then your home state may tax the prize too, often giving you credit for what the other state already took.

    This calculator applies one flat rate at a time. If the two states are different, run it twice and talk to a tax pro before you claim.

    Is the 24% federal number the tax I actually pay?

    No. The 24% is only what the IRS holds back on payout day. A jackpot puts you in the top 37% bracket, so you owe roughly 13% more when you file.

    Switch the tool to Final Liability (37%) to see the more realistic take-home number.

    Why is the first annuity payment smaller than the jackpot divided by 30?

    Because payments grow 5% every year. The first one starts low and the last one is the biggest.

    On a $525 million jackpot, an even split would be $17.5 million a year. The real first payment is closer to $7.9 million, and the year 30 payment is over $32 million. All 30 together equal the full jackpot.

    Can I switch from annuity to lump sum later?

    No. Your choice is final in almost every state, and you usually have only 60 days after claiming to decide. Some winners sell future annuity payments to a third party, but you lose a big chunk of value doing that. Compare both tabs carefully before you pick.

    Do I pay taxes on the annuity every single year?

    Yes. Each yearly payment counts as income for that year, so federal and state tax come out of each one. The year-by-year schedule in the tool shows the tax on every payment.

    One upside: smaller yearly payments may keep some of the money out of the very top bracket, which the lump sum cannot do.

    What happens to the annuity payments if I die early?

    The remaining payments do not disappear. They go to your estate or the people you name, based on state lottery rules. Some states let the estate ask for the rest as a lump sum. Your estate may also owe estate tax on the value of those future payments.

    Does the calculator include city taxes?

    Yes, for the big ones. New York City and Yonkers are listed as their own choices because they add local tax on top of state tax. New York City winners face about 14.78% combined state and city tax, the highest in the list.

    Smaller local taxes in other states are not included.

    Does buying more tickets lower my tax bill?

    No. The calculator just subtracts what you spent so you can see your true profit. Ticket cost is not a tax deduction for most people. You can only deduct gambling losses if you itemize, and only up to the amount you won.

    What if more than 10 people win the jackpot?

    The winner dropdown stops at 10, which covers almost every real split. If more tickets win, just divide the jackpot yourself and type your share into the jackpot box with 1 winner selected.

    Can I use this calculator for a lottery pool at work?

    Yes. Divide the prize by the number of people in the pool and enter your share. Just be careful: if one person claims the whole prize and hands out cash, the IRS may treat it as a gift. Pools should fill out IRS Form 5754 so each member is taxed on their own share.

    What does the present value line in today's dollars mean?

    It shows what all 30 net annuity payments are worth if you had them right now. Prices rise about 2.5% a year, so a payment in year 25 buys less than the same dollars today.

    Use this number, not the nominal total, when you compare the annuity against the lump sum.

    Are non-US winners taxed differently?

    Yes. Non-resident winners usually face 30% federal withholding instead of 24%, and tax treaties can change that. This calculator is built for US residents, so results will be off for foreign winners.

    Why don't my results match the numbers on the Mega Millions website?

    A few reasons:

    • The official cash value changes with interest rates and may not be exactly 50%.
    • The site shows the 24% withholding, not the full 37% you likely owe.
    • State tax rules and credits vary and can shift your final bill.

    Treat these numbers as a close estimate, not a legal tax filing.

    Does the calculator work for smaller Mega Millions prizes?

    Not well. It is built for jackpots, so it uses the 50% cash factor and the top tax rates. Smaller prizes are paid in full cash and may fall in a lower tax bracket. For a $10,000 win, use a general lottery tax tool instead.

    Is the 5% yearly increase guaranteed?

    Yes. Mega Millions annuity payments are set to rise 5% each year, and that schedule is fixed when you claim. The payments are backed by government bonds bought by the lottery, so the money is very safe.

    Why did my state show a 0% tax rate?

    Some places do not tax lottery winnings at all. Florida, Texas, Tennessee, Washington, South Dakota, New Hampshire, and Wyoming have no state income tax on the prize. California, Delaware, Puerto Rico, and the U.S. Virgin Islands tax other income but not lottery wins. You still owe federal tax in all of them.

    Is my information saved when I use this tool?

    No. Everything runs in your browser and nothing is stored or sent anywhere. The tool is free and you can run as many jackpot numbers as you like.
