Illinois Lotto expected value — is it ever worth playing?

Ticket price versus the sum of prize × probability, adjusted for tax and the jackpot-sharing penalty. Enter the current jackpot and see the honest number.

No current jackpot on file for this game — enter the advertised figure from the operator's site below.

24% federal withholding on prizes over $5,000 plus 4.95% Illinois state tax.

Break-even jackpot: at the tax and sales figures entered, EV per ticket reaches zero at a jackpot of about $31,781,400 (the advertised minimum is $2,000,000). Two catches: sales — and therefore sharing — rise sharply with the jackpot, and a positive expected value still says nothing about variance or ruin. See why even a +EV jackpot usually isn't worth chasing.
