Currently upgrading the same leg it's a 600€, I'm going to try to give them a calls and see how much they tell me.
If seats are still available (and you made no upgrade bids), you may get a fixed price upgrade offer during online checkin. Or request at the checkin desk/gate (there used to be a chart on TP's site which stated the gate upgrade prices for most destinations but cannot find it anymore).

The minimum ex-LIS to Brazil with Plusgrade has been indeed around 500 EUR. I’ve never used seatboost though.
