Lottery Payout Calculator
See what a lottery jackpot is really worth after federal and state tax: the cash lump sum versus the 30-year annuity, the 24% federal withholding, the extra tax owed at the top bracket, your take-home pay and an after-tax comparison of both options. Example: a $100 million jackpot becomes about $48 million as cash and roughly $27.8 million after a 37% federal and 5% state tax.

How to use the Lottery Payout Calculator
- Enter the advertised jackpot and the cash option percentage.
- Choose your federal tax rate and enter your state tax rate.
- Press Calculate to compare the lump sum with the 30-year annuity after tax.
Formula and method
Cash value = jackpot x cash percentage. Take-home = cash x (1 – federal rate – state rate). Annuity first payment = jackpot / sum of (1 + growth)^k for k = 0 to 29, then each payment rises by the growth rate. After-tax annuity = payments x (1 – federal rate – state rate).
Worked example: $100 million jackpot
| Item | Amount |
|---|---|
| Cash value (48%) | $48,000,000 |
| Federal tax at 37% | $17,760,000 |
| State tax at 5% | $2,400,000 |
| Take-home lump sum | $27,840,000 |
| Annuity first payment | $1,505,000 |
| Annuity total before tax | $100,000,000 |
Lump sum versus annuity
| Lump sum | Annuity | |
|---|---|---|
| Payout | One payment | 30 payments over 29 years |
| Value | Cash value only | Full advertised jackpot |
| Control | Invest yourself | Fixed, rising payments |
| Tax timing | All in one year | Spread across years |
Why the withholding is not the final tax
The IRS withholds 24 percent from large prizes, but winnings are added to your other income and taxed at the marginal rates, up to 37 percent for a prize this size. Because a lump sum lands in a single year, most of it falls in the top bracket.
Sensible first steps after a big win
Sign the ticket, keep it safe, and get advice from a tax professional, a financial adviser and a lawyer before you claim. Some states allow anonymity or claiming through a trust.
Frequently asked questions
How much of a jackpot do I get as a lump sum?
About 45 to 50 percent, depending on interest rates when the prize is set.
How much tax is taken from lottery winnings?
24% federal withholding, then up to 37% federal in total, plus state tax where it applies.
Is the annuity better than the lump sum?
The annuity pays the full headline amount over 30 years, but the lump sum can be invested immediately. The right choice depends on discipline, taxes and goals.
How does the annuity grow?
Many multi-state games raise each annual payment by 5 percent.
What if I share the jackpot?
Enter the number of people, and the calculator splits the jackpot first.
Do all states tax lottery winnings?
No. Several states have no state income tax.
