JackpotKeep is not affiliated with Powerball, Mega Millions or any state lottery, and nothing on this site is tax, legal or financial advice.
Last updated October 23, 2026. Questions about this page: [email protected].
No affiliation
Powerball is operated by the Multi-State Lottery Association and its member lotteries. Mega Millions is operated by its participating lotteries. We are an independent publisher. We do not sell tickets, administer games, or speak for any lottery.
Not tax advice
The calculators apply published rates to a simplified fact pattern. They do not account for your income, filing status, deductions, residency history, trusts, or state-specific claim rules. A licensed tax adviser in your state is the only source of advice for your situation.
Estimates and rounding
Cash values, tax rates and take-home amounts are estimates. Cash values move with interest rates at every draw. We round to the nearest dollar in tables and to one decimal place in summaries, so components may not add exactly.
No guarantee of winnings
Nothing here improves your odds. The jackpot odds are about 1 in 292 million for Powerball and 1 in 290 million for Mega Millions. Play within your means, and treat the money as spent.
External sources
We link to official sources so you can verify any figure. Those sites can change; a broken link is not a change in the law.
If you have won
Sign the ticket, store it safely, tell no one, and speak to a tax attorney and a fee-only adviser before you claim. Our claiming guide covers the sequence; it is not a substitute for professional advice.
