I'll be leaving with approx $7k USD and current exchange puts that about 5.3k Euros; for budgeting (and sanity purposes I might add) I calculate all my budgets in USD using budgetyourtrip.com
This site basically told me that Switzerland is running about $190/day AVERAGED but I calculated roughly $145/day since there are some expenses I wouldn't spend on. not to mention some of my pre purchases that technically don't count towards the overall trip. Again, in USD this translates to about $2k for 14 days and then 10 days in Germany would cost me roughly $100/day based on the averages would be about $1k USD bringing my total projected expenses for 3 weeks to $3k not including exit airfare to Argentina ($820).
Does that number sound low to you? It does to me, I spent roughly $1k/per person in Honolulu for barely a week; tell me that's not messed up! Here's the good thing, if its low; I have $4k to play with until I receive my next payment which will yield $4k of play money after paying all my bills (and if I truly do end up with left over funds that'll yeild about $8k with rollover.
I want to be sure I'm budgeting correctly; this is my concern not how much (well sure I'd be concerned, but as long as I don't stray too far from the budget who cares?) I'm spending but whether that's a proper assertion of a proper budget for 3 weeks.
