Manchester City are due the hefty figure from Barca as part of the deal that took Suarez to the Camp Nou.
The 23-year-old spent two years in City's academy system before returning to his homeland in 2013 on a four-year contract.
Barcelona paid a small fee of €3.2m at the time, but the contract had a number of clauses to ensure City could benefit if Suarez went on to be a star for the Spanish giants.
He initially struggled at the Nou Camp and was sold to Villarreal in 2015, but was re-signed the following year.
The terms of his transfer from the Etihad, however, still remained and he has now gone on to play a significant role in the starting XI.
Suarez made his 40th appearance in the win against Getafe, meaning a fourth instalment of €800,000 was due.
Pep Guardiola's side are set to receive €800,000 for every 10 games that Suarez represents Barcelona, up to 100 games.
With the initial €3.2m and the four payments of €800,000 adding to €3.2m, Barca have currently paid €6.4m to Manchester City. The signing could, therefore, finally add up to €11.2, with six more instalments to come.
