DES MOINES, Iowa -- An estimated $625 million jackpot is on the line in Saturday's Powerball drawing.

It would be the seventh-highest U.S. lottery jackpot ever. The estimated lump sum payout would be $380.6 million before taxes. The odds of winning are roughly 1 in 292.2 million.

No one has won the Powerball jackpot since the day after Christmas. Twenty-four drawings since then have failed to produce a winner, including the drawing on Wednesday.

The buyers of three tickets shared the country's largest jackpot. It was a nearly $1.59 billion Powerball prize drawn on Jan. 13, 2016. A South Carolina purchaser won a $1.54 billion Mega Millions jackpot. That was the nation's second-largest lottery prize ever.
