Introduction
Winning the lottery is exciting, but it can be hard to know how much money you will actually take home each year. This lottery annuity calculator helps you figure that out. It breaks down your annual lottery payments year by year, shows how much goes to federal and state taxes, and tells you what you keep after taxes.
Most big lotteries like Powerball and Mega Millions pay winners in annual installments that grow over time. Each payment is a little bigger than the last. This calculator uses that growing payment structure to build a full payout schedule for you. Just enter your jackpot amount, pick your state, and choose your tax filing status. The tool does the rest.
You will also see how inflation affects the buying power of your future payments. A dollar today is worth more than a dollar 20 years from now. The inflation-adjusted column shows what each payment is really worth in today's dollars. On top of that, the calculator gives you a step-by-step breakdown of every formula it uses, so you can see exactly how the math works.
How to Use Our Lottery Annuity Calculator
Enter your lottery prize details and tax info below. The calculator will show you how much money you get each year, how much goes to taxes, and what your payments are worth after inflation.
Advertised Annuity Jackpot: Type in the total jackpot amount shown on the lottery. This is the full prize before taxes, not the cash option. You can enter up to $9,999,999,999.
Number of Payment Years: Enter how many years your annuity payments will last. Powerball pays 30 graduated payments over 29 years,2 and Mega Millions pays one immediate payment followed by 29 annual payments.1 You can pick any number from 2 to 40.
Annual Payout Increase (%): Enter the percentage each payment grows compared to the year before. Mega Millions payments each grow 5% over the one before,1 and Powerball payments also rise each year.3 Set this to 0% if your payments stay the same every year.
First Payment Year: Enter the calendar year you expect to receive your first annuity payment. This is usually the same year you win.
Assumed Annual Inflation Rate (%): Enter an inflation rate to see what your future payments are worth in today's dollars. A common estimate is 3%. This does not change your actual payout or tax amounts.
Federal Tax Filing Status: Pick your federal tax status from the dropdown. Choose "Withholding (24%)" to see the standard amount held back by the lottery, or pick your actual filing status to estimate taxes at the top bracket rate of 37%.
State / Territory: Select the state or territory where you live. Each state has a different tax rate on lottery winnings. Some states like Florida and Texas have no state tax on prizes.

What Is a Lottery Annuity?
When you win a big lottery prize like Powerball or Mega Millions, you usually get two choices for how you receive your money: a lump sum (one big payment right away) or an annuity (smaller payments spread out over many years). A lottery annuity splits your total jackpot into yearly payments, often over 30 years.
How Lottery Annuity Payments Work
Most lottery annuities are growing annuities. This means each yearly payment is a little bigger than the one before it, usually by about 5% per year.1 Your first payment is the smallest, and your last payment is the largest. The total of all payments adds up to the full advertised jackpot amount.
For example, a $20 million jackpot paid over 30 years with a 5% annual increase starts with a payment around $307,000 in year one. By year 30, that payment grows to over $1.3 million. Every dollar of every payment is still subject to taxes.
Taxes on Lottery Winnings
Lottery winnings are taxed as regular income. The federal government withholds at least 24% from each payment.4 If you are in the top tax bracket, you may owe up to 37% in federal taxes.5 Many states also take a cut. Florida and Texas have no state income tax,6 California does not tax winnings from the California Lottery,7 while New York's top rate is over 10%.6
Each annuity payment gets taxed in the year you receive it. This calculator shows you the federal tax, state tax, and net take-home amount for every single payment year.
Annuity vs. Lump Sum
The lump sum (also called the cash option) is smaller than the advertised jackpot; this calculator estimates it at 60%. You get less money upfront, but you get it all at once. The annuity pays you the full jackpot amount, but spread over decades. Which option is better depends on your financial goals, your tax situation, and how you plan to invest.
Why Inflation Matters
Money loses buying power over time because of inflation. A dollar today buys more than a dollar will buy 20 years from now. This calculator includes an inflation-adjusted column so you can see what each future payment is really worth in today's dollars. Even with a 5% annual increase, high inflation can eat into the real value of later payments.
