Is the calculator free to use?

Yes, on any site, commercial or not, with no sign-up and no key. Please keep the "Calculator by Bits & Odds" line under it: it is how your readers can check where the figures come from.

Does it track my readers or show ads?

No. It loads one script from bitsandodds.com and nothing else: no cookies, no local storage, no analytics, no ads, and it sends nothing back. Your own consent banner has nothing new to declare.

How does it stay up to date?

The script is rebuilt with the new figures after every Powerball and Mega Millions drawing, once the lottery publishes the next jackpot, so the calculator on your page changes with it. If a drawing has been held and the new jackpot is not out yet, it says so rather than showing the old one as current.

Can it open on my state?

Yes. Choose the state above before you copy the code (it becomes data-state="texas", or ?state=texas in the iframe address). Two-letter codes work too. Readers can still pick any of the 46 jurisdictions that sell either game.

Which figure is "after taxes"?

The big number is what one winner taking the cash keeps once the whole federal bill is paid at filing (2026 brackets, single filer) and the state's withholding rate is applied. Below it are the cheque, which is the cash value less the 24% federal and the state withholding held back at payout, and the annuity, taxed payment by payment. The jackpot page has every state side by side.

Add a jackpot after-tax calculator to your site

A free Powerball and Mega Millions calculator for your jackpot coverage: the current jackpot, its cash value, and what a winner keeps after federal and state tax in each of the 46 jurisdictions that sell the games. It updates itself after every drawing.

Right now the Powerball jackpot for Wednesday, October 28, 2026, 10:59 pm ET is $716 million, with a cash value of $307.2 million; a single winner taking the cash keeps about $193.6 million in a state with no lottery tax. That is the figure the calculator below opens on, and the one on the Powerball jackpot page.

What your readers see

The jackpot and its cash value for the coming drawing, as the lottery publishes them.
What a winner keeps, cash option: the cash value less the whole federal bill at filing (2026 brackets, single filer; a jackpot sits almost entirely in the 37% bracket) and the state's withholding rate.
The cheque: what is paid out after the 24% federal and the state's withholding are held back, before the rest of the federal bill falls due.
The annuity, the first year's payment and all 30 years, each payment taxed in its own year.
A state picker with every state that sells the game (46 sell both), opening on the one you choose.

State figures are each state's withholding rate on a resident's prize, last checked October 18, 2026: an estimate of the final state bill, and labelled that way. The arithmetic is the same as on the Powerball and Mega Millions jackpot pages, row for row, and the tax calculator takes any amount, filing status and rate.
