Plymouth's third-round replay with Liverpool will help Argyle earn more than £1m from the FA Cup, said the League Two club's chairman James Brent.
The Pilgrims put on a dogged defensive display against a much-changed Liverpool side to draw 0-0 at Anfield and set up a replay at Home Park.
Argyle have already had two televised ties, with a third likely, as well as their share of Sunday's 52,692 gate.
"It's approximately 20% of our turnover," Brent told the BBC.
Argyle went into administration in March 2011 and narrowly avoided relegation from the Football League in 2012.
