How the math works
- Graduated annuity (Powerball / Mega Millions): payments grow 5% per year. First payment
P₁ = J × g / ((1+g)ⁿ − 1), thenPₚ = P₁(1+g)ⁿ⁻¹. The 30 payments sum to exactly the advertised jackpot. The first payment is immediate (annuity-due). - Federal tax: 2026 IRS brackets (Rev. Proc. 2025-32) applied per payment for the annuity and once for the lump sum, after the standard deduction ($16,100 single / $32,200 married filing jointly). Single: 10% to $12,400, 12% to $50,400, 22% to $105,700, 24% to $201,775, 32% to $256,225, 35% to $640,600, 37% above. This is why spreading payments across years usually lowers the total federal bill.
- State tax: the selected top marginal rate times each gross payment — an estimate only. California, Delaware, New Hampshire, and Tennessee do not tax lottery winnings at the state level; Alaska, Florida, Nevada, South Dakota, Texas, Washington, and Wyoming have no income tax.
- Present value:
PV = ∑ netₚ/(1+r)ⁿ⁻¹with your discount rate. Break-even rate is the rate where PV equals the after-tax lump sum (solved by bisection). - The race: lump sum compounds as
net×(1+r)ⁿ; each annuity payment is invested from the year it arrives.
Frequently asked questions
Should I take the lump sum or the annuity if I win the lottery?
There is no universal answer — it depends on the discount rate you assume. Run the numbers above: a $500,000,000 Powerball jackpot as a single filer with no state tax leaves about $316,499,992.50 after tax spread over 30 years, versus about $163,849,999.75 after tax today as a lump sum (52% cash option). But at a 6% discount rate the annuity is worth only about $125,118,007.36 in today's dollars — less than the lump sum. The break-even rate for that scenario is about 4.04%: if you can reliably earn more than that investing, the lump sum wins in present-value terms.
How much is a $500 million Powerball jackpot actually worth?
Using the calculator's defaults (single filer, no state tax, 52% cash option): the first annuity payment is $7,525,717.54 and the 30th is $30,976,873.85. After federal tax, the 30 payments total about $316,499,992.50. The lump sum after tax is about $163,849,999.75. These are estimates — your state tax and other income change the result.
How are Powerball and Mega Millions annuity payments calculated?
Both pay 30 annual installments that increase 5% each year. The first payment is P1 = jackpot × 0.05 / (1.05^30 − 1), roughly 1.505% of the jackpot — about $7,525,717.54 on a $500,000,000 jackpot. Each later payment is 5% larger, so the final one is about $30,976,873.85. The first payment arrives almost immediately, not a year later.
Mega Millions annuity vs cash: what does an $800 million jackpot pay?
As a worked example (married filing jointly, no state tax, 60% cash option): the first of 30 graduated payments is $12,041,148.06 and the last is $49,562,998.16. After-tax annuity total: about $506,692,485.00. After-tax lump sum: about $302,489,749.50. At an 8% discount rate the annuity's present value is about $156,890,055.33 and the break-even rate is about 3.09%. Your own inputs will differ — adjust them above.
Why is the lump sum so much smaller than the advertised jackpot?
The advertised jackpot is the sum of 30 years of future payments. The cash option is the present value of those payments — what the prize pool is actually worth today — typically 50% to 60% of the headline number. A $500,000,000 jackpot at a 52% cash ratio means $260,000,000 in hand before tax.
How are lottery winnings taxed?
The IRS treats winnings as ordinary income. The lottery withholds 24% federal immediately, but large wins are taxed up to the top 37% marginal rate at filing time — so most jackpot winners owe more in April. State tax depends on where you bought the ticket: New York charges up to 10.9%, while California, Delaware, New Hampshire, Tennessee, Alaska, Florida, Nevada, South Dakota, Texas, Washington, and Wyoming charge nothing on lottery winnings. With the annuity, each payment is taxed in the year you receive it; with the lump sum, everything is taxed at once.
What is the break-even discount rate?
It is the investment return at which the annuity's present value exactly equals the after-tax lump sum. For the $500,000,000 Powerball example above (single, no state tax, 52% cash) it is about 4.04%. Earn more than that on your investments and the lump sum is the better deal in today's dollars; earn less and the annuity wins. Move the discount-rate slider to see the verdict flip.
Does the annuity really save on taxes?
Sometimes. Because federal tax is progressive, splitting a huge win into 30 yearly payments can keep more of it in lower brackets — in the $500,000,000 single-filer example, the annuity's total after-tax take is about $316,499,992.50 versus about $163,849,999.75 for the lump sum, a tax-spreading advantage. But early payments can still land in the 37% bracket, so the benefit is smaller than many people assume. The calculator applies the real 2026 brackets to every payment so you can see the exact difference.
What happens to annuity payments if the winner dies?
The remaining scheduled payments become part of the winner's estate and continue to the heirs or designated beneficiaries on the same schedule. They do not accelerate into a lump sum, and estate tax may apply on top of income tax — another reason to get professional advice for large wins.
Can tax rates change during the 30-year annuity?
Yes. Federal brackets, rates, and state tax laws can all change over three decades, which adds uncertainty the lump sum avoids. This calculator uses 2026 federal brackets and the state rate you select, held constant — treat long-horizon results as estimates, not promises.
How is this different from an immediate annuity calculator?
An immediate annuity (SPIA) is an insurance product: you hand an insurer a premium and get lifetime income based on mortality tables. A lottery annuity is just a deferred prize payout over a fixed term with no insurance or mortality pricing involved. Different products, different math — use our immediate annuity calculator for the insurance version.
Is this financial advice?
No. This calculator produces planning estimates for education only — not financial, tax, or legal advice. Lottery decisions involve taxes, estate planning, and investment risk that no online tool can fully capture. Consult licensed professionals before choosing a payout option.
