FIFA processed international transfer deals worth $3 billion (?2.25 billion) in 2011, and said Thursday it will share payment details with UEFA to help monitor European financial fair play rules.
FIFA allowed 11,500 players to make cross-border moves in the first calendar year operating its Transfer Matching System, which aims to curb money laundering and corrupt deals.
The mandatory online project requires buying and selling clubs to input matching information, including payment schedules, before a transfer is approved.
FIFA head of compliance Isabelle Solal said the information was useful to UEFA, which wants clubs to pay their football debts as a condition of entering the Champions League.
''Part of the information we do provide them (UEFA) is on declared installment payments, and whether or not we have received proof of that payment,'' Solal said in a conference call.
FIFA's research revealed that the average transfer fee across all international deals was $1.5 million (?1.1 million).
The average salary in a selection of 10 countries worldwide was $244,000 (?183,000) - though the typical player was ''not paid as much as you would expect,'' the study said.
Brazilian players were most in demand, with more than 1,500 transferred internationally last year. Players from Argentina and France were next on the list.
The figures exclude players moving between clubs in the same country, such as Chelsea's 50 million pound ($80 million; ?60 million) signing of Fernando Torres from Liverpool.
FIFA believes its transfer monitoring - and powers to sanction clubs and national associations - has helped clean up a football trade market that was regarded as ''pretty crazy'' and ripe for corruption.
''If there any inconsistencies then questions will be asked,'' said Mark Goddard, general manager of FIFA's TMS subsidiary operation.
FIFA said its compliance team intervened in 700 cases last year, but did not detail any specific disciplinary action taken.
However, Goddard acknowledged it is tough for TMS to wipe out money laundering and third-party ownership of players' transfer rights, which is illegal in England.
''I don't think it's a silver bullet that solves everything,'' he said. ''We are trying to make (money laundering) something that they reconsider whether they want to use football clubs to do this.''
FIFA's survey also gives only a partial picture of how much money is taken by agents.
Transfer matching rules required clubs to tell FIFA they paid $130 million ($98 million) to middle men, though players' payments to their agents are not accounted for.
FIFA calculated that agents received an average $240,000 (?180,000) commission - 16 percent of the average transfer fee - yet the governing body has long been working on proposals to limit an agent's maximum cut to three percent.
FIFA pointed to real progress in curbing ''child trafficking'' transfers, as TMS requires details of all international moves involving registered players under the age of 18.
