"Our prices remain extraordinarily competitive, particularly compared with other clubs in the top half of the table," said a Liverpool spokesman.
Liverpool are £351m in debt and were put up for sale by co-owners Tom Hicks and George Gillett earlier this year.
The American pair's ownership of the Reds has been a long-running source of discontent for many fans, who are unhappy with the way the club is being run, and there have been regular protests and public disputes.
In the aftermath of Rafafel Benitez's exit on Thursday, Anfield was the starting point for more protests against the American owners, with some supporters carrying banners reading "Gracias Rafa".
The Liverpool season ticket price rise announcement comes on the day that a Liverpool fans group - ShareLiverpoolFC - announced plans to underwrite the costs of organising a fan share issue.
The ShareLiverpoolFC scheme, which has the backing of Liverpool greats John Aldridge and John Barnes, envisages a £500 minimum investment to buy one share.
If all 35,000 registered ShareLiverpoolFC fans were to buy a share that could raise £40m though the group hopes more supporters will buy shares.
"If the sum raised is insufficient to take a majority stake in the club, the board would seek to partner a suitable majority owner by purchasing a minority share," said a ShareLiverpoolFC statement.
Last week, ShareLiverpoolFC and another Liverpool fan group the Spirit of Shankly rejected a merger of the two organisations.
The Spirit of Shankly now intends to launch a credit union scheme to collect payments from fans to establish a fund for the purchase of a stake in the club.
The scheme will allow members to make monthly payments to reach the starting point of £500 per fan.
Manchester United season ticket holders are currently paying up to £931 to watch their club.
