TSV 1860 Rosenheim, Schweinsteiger's former club, were entitled to a cut of any future fee the player was transferred for, after he left them to join Bayern as a youngster in 1998.
The club announced on their official website on Wednesday the extent of their cut, paid in two instalments, and that the fee paid for the 31-year-old was significantly less than reported by multiple English sources.

A club statement read: "The transfer fee adds up to €9m (£6.54m). We have been credited for two years [that Schweinsteiger spent at the club].
"We will receive the payment in two instalments, and after deducting the advisor and legal costs, we will receive €19,000 (£13,770). We have already received the first instalment in August."
"We are delighted about Bastian's incredible career and also that we profit from it financially as his first club.
"For us, this is again an incentive to continue to put a lot of power in our youth. We will use the money for our high-quality football education."
The astounding revelation of a player of Schweinsteiger's quality being sold for such a minimal fee comes as a massive surprise, though the fee could eventually rise dependant on the player's success at United.
The Germany captain is set to start in the heart of United's midfield in Saturday evening's clash with Liverpool after playing a key role for his country over the international break.
The midfielder has won eight Bundesliga titles, seven DFB-Pokal, the Champions League once and, to top it all off, the 2014 World Cup, and appears to be adjusting to life in Manchester well given his string of impressive performances so far, though fitness does remain an issue.
