Albion will receive a near £1 million boost towards cutting their losses if they win Monday’s FA Cup fifth round replay at Hull City.
The Seagulls’ TV and prize money from the competition will rise to almost seven figures with victory at the KC Stadium.
A further £123,750 has been added to the pot for live coverage on ITV4 of the rematch with the Premier League club.
Monday’s 1-1 draw at the Amex, screened by BT Sport, was worth £247,500.
Albion earned £157,500 in prize money from their victories in the previous rounds against Reading and Port Vale.
Beating Hull will be worth a further £180,000 and would secure another bumper TV payout for coverage of the quarter-final at home to Gus Poyet's Sunderland.
An FA Cup windfall is a timely tonic to Albion's finances. They have targeted slashing their annual loss from £14.7 million to £8 million in order to comply with Financial Fair Play regulations.
The club have encouraged season ticket holders and club members to make the journey to Humberside on Monday evening by offering to cover the cost of a ticket.
Chief executive Paul Barber said: "The potential for progressing further in The FA Cup is an exciting prospect and, as ever, our supporters can play an important role in helping the team on the night.
"We have had wonderful support from our fans all season and we hope that this gesture for our most committed season ticket holders and members will go some way towards making the long trip north more affordable for our fans, and act as a small thank you for the great support we receive."
Ticket rebates will be applied to supporters' e-cash accounts within seven days of the replay. Prices range from £1 for under ten's to £15 for adults and can be booked from today online, by phone or at the Amex. Tickets go on general sale from 9am tomorrow.
