Data Source & Methodology

This calculator provides an *estimate* of lottery winnings. The final amount may vary based on specific lottery rules, state withholding, and individual tax situations.

  • Authoritative Source: Federal tax calculations are based on the U.S. progressive tax brackets for the 2024 tax year, as published by the IRS in Revenue Procedure 2023-34. The top federal marginal rate of 37% is applied to income over $609,350 for single filers ($731,200 for married).
  • State Taxes: State tax estimates are based on 2024-2025 top marginal income tax rates. Some states (like California, Florida, and Texas) do not levy a state tax on lottery winnings, while others (like New York and Maryland) tax them as income.
  • Methodology: All calculations are based strictly on the formulas and data provided by these sources. We do not account for local taxes, pre-existing income, or other deductions.

The Formulas Explained

The calculation differs significantly between the lump sum and annuity options.

1. Lump Sum (Cash) Payout

This is a one-time payment. The entire cash value is taxed as ordinary income in a single year.

$ Tax_{Federal} = CalculateProgressiveTax(CashValue, Brackets_{Federal}) $

$ Tax_{State} = CashValue \times Rate_{State} $

$ NetPayout = CashValue - Tax_{Federal} - Tax_{State} $

2. Annuity Payout

The advertised jackpot is divided into 30 annual payments. You are only taxed on the amount you receive *each year*.

$ Payment_{Annual} = AdvertisedJackpot / 30 $

$ Tax_{Federal/Year} = CalculateProgressiveTax(Payment_{Annual}, Brackets_{Federal}) $

$ Tax_{State/Year} = Payment_{Annual} \times Rate_{State} $

$ NetPayout_{Annual} = Payment_{Annual} - Tax_{Federal/Year} - Tax_{State/Year} $

Glossary of Variables

Advertised Jackpot
The total prize amount advertised by the lottery, representing the sum of 30 annual payments.
Lump Sum (Cash) Value
The one-time payout offered instead of the annuity. It is the "present value" of the jackpot, typically 50-60% of the advertised amount.
Gross Payout
The amount of money you receive before any taxes are deducted (either the full Lump Sum or one Annual Payment).
Federal Tax
Taxes owed to the U.S. federal government, calculated using a progressive bracket system.
State Tax
Taxes owed to your state of residence. Rates vary, and some states have no income tax or do not tax lottery winnings.
Net Payout
The final "take-home" amount after all federal and state taxes have been deducted.

How It Works: A Step-by-Step Example

Let's walk through a scenario:

  • Advertised Jackpot: $500,000,000
  • Lump Sum (Cash) Value: $250,000,000
  • Filing Status: Single
  • State: New York (Top marginal rate: 10.9%)

Case 1: Lump Sum Payout

  1. Gross Payout: $250,000,000
  2. Federal Tax: The $250M income is taxed progressively. The vast majority falls into the top 37% bracket, resulting in an effective federal tax of ~$92,481,365.
  3. State Tax: $250,000,000 \times 10.9\% = $27,250,000
  4. Net Payout: $250M - $92.5M - $27.25M = ~$130,268,635 (one-time payment)

Case 2: Annuity Payout

  1. Annual Gross Payout: $500,000,000 / 30 = $16,666,667 per year
  2. Federal Tax (per year): This $16.7M income is taxed, resulting in an effective federal tax of ~$6,047,365 per year.
  3. State Tax (per year): $16,666,667 \times 10.9\% = $1,816,667 per year
  4. Net Payout (per year): $16.7M - $6.05M - $1.82M = ~$8,802,635 (each year for 30 years)

Frequently Asked Questions

Which is better: lump sum or annuity?

It's a personal choice. The **lump sum** gives you all the money at once, allowing for large-scale investments, but it's taxed heavily in a single year. The **annuity** provides a stable, guaranteed income for 30 years and often results in a lower effective tax rate each year. However, its total value is subject to inflation. Consult a financial advisor.

Are lottery winnings always taxed?

Yes, in the United States, lottery winnings are considered ordinary taxable income by the IRS. Most states also tax them, with a few exceptions (like California, Florida, and Texas).

Why is the cash value so much lower than the advertised jackpot?

The advertised jackpot is the total amount of 30 annual payments. The lump sum (cash value) is the "present value" of that 30-year annuity, meaning it's the amount of money the lottery commission would need to invest *today* to be able to make those 30 payments. The difference is the (guaranteed) investment interest the lottery would have earned.

Do I pay state tax if I bought the ticket in another state?

This is complex and depends on both your state of residence and the state where you bought the ticket. Many states have "credit for taxes paid" agreements. However, you are almost always liable for taxes in your home state (where you file). This calculator assumes you pay taxes in your state of residence.

What if I split the prize with other people?

If you split the prize (e.g., an office pool), you only input *your share* of the jackpot and cash value into the calculator. The tax burden is divided among all winners based on their individual shares.
