West Coast Eagles membership prices for next year have risen up to 13 per cent, with family memberships among the hardest hit.
The club generated a profit of $2.76 million last year and took $14.87 million in membership revenue.
Budget family memberships for 2012, offering reserved seats for two adults and two children, jumped from $630 to $702, while standard adult membership rose from $355 to $385.
The biggest percentage increases were for restricted view child and budget child memberships, up from $114 to $129.
Prices for Fremantle Dockers memberships next year have risen up to 8 per cent.
Budget family memberships for two adults and two children have increased from $640 to $681, and standard adult membership has risen from $348 to $365.
West Coast's chief operating officer Richard Godfrey said a big portion of Eagles' revenue went to making sure the club was competitive and contributing to the development of football in WA via royalty payments to the WA Football Commission.
He said memberships included public transport and the levy paid to Transperth would increase next year.
