Lottery Annuity Calculator

Build an illustrative annuity payment schedule for any total. Enter the annuity value, number of payments, frequency, and annual increase to see each payment and the running total.

The nominal total of all payments.

Growth per payment. 0 = equal payments. Illustrative.

Fixed vs Growing Payments

A fixed annuity pays the same amount every period: total divided by the number of payments. A growing annuity increases each payment by a fixed percentage — early payments are smaller, later payments larger, and the nominal total stays the same. Mega Millions uses a 5% growing structure; Powerball's official rules describe graduated payments without publishing a fixed rate.

Schedules built here are illustrative custom scenarios. They show pre-tax payment amounts only — for per-payment tax estimates, use the lottery payout calculator , which taxes each payment in its year.

How We Calculate

The schedule builder uses the shared annuity engine. For equal payments, each payment is the total divided by the payment count. For growing payments, the first payment is solved from the geometric series so all payments sum to the annuity total, then each payment is rounded to the cent with the final payment adjusted so the schedule totals exactly. No tax is estimated here — this is a pre-tax illustrative schedule.

How We Calculate

  1. Start with the selected lottery amount. Enter the advertised jackpot and the cash option (or choose the annuity to estimate one annual payment).

  2. Determine the cash or taxable amount. For a lump sum, the cash option is the taxable amount. For an annuity, each annual payment is taxed in the year it is received.

  3. Apply applicable federal tax rules. Lottery winnings are taxed as ordinary income. The calculator subtracts the standard deduction for your filing status, then applies that year's progressive federal tax brackets.

  4. Apply applicable state rules. The calculator applies the state's configured planning rate. States that do not tax lottery winnings show $0 state tax. Local and city taxes are not included.

  5. Calculate estimated total tax. Estimated federal and state taxes are added together for the total estimated tax liability.

  6. Calculate estimated take-home amount. Estimated total tax is subtracted from the taxable amount. This is an estimate of final liability — withholding shown separately is what may be held back when you are paid, and it is credited against this liability.

Results are estimates for informational purposes only — not tax, legal, or financial advice. Your actual tax bill depends on your full tax return, the lottery's rules, and the laws in effect when you claim the prize.

Frequently Asked Questions

How does a lottery annuity work?

A lottery annuity splits the advertised jackpot into a series of payments — typically 30 annual payments. Each payment is taxed as ordinary income in the year you receive it. Powerball pays 30 graduated payments over 29 years; Mega Millions pays one immediate payment plus 29 annual payments, each 5% larger than the last.

Is this schedule the official payout for a lottery?

No — this tool builds illustrative custom scenarios. It models any total, payment count, frequency, and growth rate you enter. For a lottery's verified structure, use the payout calculator and select Powerball or Mega Millions, which applies the published annuity rules.

How are growing annuity payments calculated?

With a positive annual increase, payments form a geometric series: each payment is larger than the last by the growth rate, and the first payment is solved so the nominal total of all payments equals the annuity value you entered. With 0% increase, every payment is simply the total divided by the number of payments.

Are annuity payments taxable?

Yes. Each payment is taxed as ordinary income in the year received — federally always, and by most states. To estimate the tax on each payment, run the same numbers through the lottery payout calculator, which taxes every payment with the site's tax engine.

Why is the annuity total bigger than the cash option?

The annuity total is the nominal sum of payments spread over decades; the cash option is the present value of that stream sitting in the prize pool today. The difference is the time value of money, not a bonus — and it moves with interest rates.
