Mega Millions is played in 45 U.S. states, so your payout will vary depending on some factors, including whether or not you have to pay state taxes. Of course, the accuracy of the online calculators may not be fully in line with what you actually end up with. So if you happen to win, experts say you should consult with a financial advisor.

Now, your winnings depend on whether you decide to take the lump sum payment or the annuity payout. According to Mega Millions website, "the annuity is paid out as one immediate payment followed by 29 annual payments. Each payment is 5% bigger than the previous one. This helps protect winners’ lifestyle and purchasing power in periods of inflation."

For Friday's jackpot, the cash option (or lump sum payout) would be $648.2 million. According to annuity.org, federal taxes reduce lottery winnings immediately. But winners who take annuity payouts can come closer to getting the actual jackpot amount than lump-sum takers.
