Eredivisie clubs lost a combined €71.8million (Dh346.6m) during the 2009/10 season, according to figures released by the KNVB.
The numbers were announced at a press conference which the KNVB boasted made Dutch football "uniquely transparent".
"There have been many figures mentioned in the media, but these are the only correct figures," Frank Rutten, the director of the umbrella organisation of Eredivisie clubs, said on the KNVB website.
The losses were blamed on a decline in revenue made from player sales overseas.
Eridivise league leaders PSV will face a tough task in tomorrow's clash with fifth-placed Roda. Groningen should hope to pick up three points against Excelsior today.
Only six points separated the top six sides before last night's clash between second-placed Twente and Heracles, who were hovering just above the relegation zone.
