The Daily Mail reports that West Ham will pay an initial £36million, which will be followed by add-ons worth up to £6.5million.
Haller is expected at the club on Tuesday after German newspaper Frankfurter Rundschau claimed Manuel Pellegrini was prepared to offer weekly wages of £100,000 per-week.
And the news was confirmed by the club in a Twitter announcement later on Tuesday.
Eintracht and @WestHamUtd have agreed terms for the transfer of @HallerSeb. Haller has now been cleared to undergo a medical in London. If all goes to plan then Haller will sign with the Hammers. #SGE pic.twitter.com/VpQNxM4y0I

The 25-year-old was in great form in the Bundesliga last season, scoring 15 goals and assisting a further nine in 29 appearances.
West Ham fans will be breathing a huge sigh of relief on Tuesday morning after it looks like the club is finally going to solve the striker problem. Despite this confirmation, though, they will know more than anyone not to get too excited over the transfer update until Haller is pictured in a Hammers shirt. The 6’3″ colossus [Transfermarkt] would be more than capable of living up to the hype of being West Ham’s most expensive signing, with his goal record speaking for itself. Haller averaged a goal or assist every 97.5 minutes last season [Transfermarkt] and would bring a great physical presence alongside the likes of Felipe Anderson. Haller won an average of 8.3 aerial battles per 90 minutes last season [WhoScored], an impressive average which could see his ability in the air bring West Ham’s more tactical players into play in the final third. With a medical set, West Ham fans should be able to celebrate in the coming days, as they finally look set to get their man.
