If you do the calculations for level 1 based on the DMG treasure parcels it works out to around 500 gp equivalent per encounter. Higher levels go MUCH higher.
As an aside I'm of the point of view that this system (as with all previous systems I've ever looked at) are way heavy on giving out treasure, but it is really entirely up to the DM. Going 'by the book' characters will have tons of cash and more magic items than you can shake a stick at, but that's fine if it works for your game. If you want to run a 'low magic' type of game like I prefer then you may want to give out a lot less than 4 items per level. Listen to your players, if they think they're getting short changed on treasure, then maybe give them an extra big treasure at some point. You can always find a way to relieve them of excess gold later on too!
