Podolski will earn a total of €4.5 million per season (including bonuses) which puts him on par with Wesley Sneijder. Podolski currently earns €3.25 million per season at Arsenal.
The Germany international is set to put pen to paper on a three year deal with Galatasaray over the coming days.
Galatasaray have been linked with Podolski for the past four seasons and made an offer for the 30-year-old striker in January but he joined Inter on loan.
The former Bayern Munich player who has a year remaining on his contract with Arsenal, had an unsuccessful spell with the Serie A giants scoring just one league goal.
Podolski won the World Cup with Germany last season and wants regular first team football to keep his place in the national team side.
Galatasaray will participate in the UEFA Champions League next season after securing their 20th league title this season.
