That budget calculator is pretty helpful. I checked out the Europe countries and they seem to be pretty accurate from what I remember spending.

I got an error message, "Host is unreachable"

That's incredible! With a little more work that could be one of the most used applications for foreign travel! Keep tweaking it and making it better, I see a LOT of potential!!

that is definitely a great idea for travelers to get an idea on how much they can spend or afford.

Thanks for the feedback guys!!

I will be speaking to my hosting company about that error message! grrrrrrr

I am adding a new category soon, internet costs as most travellers will spend money on emailing.

Can anyone think of anything else? ;)

on that emailing part you said you want want to combine the phone cards, and maybe add some categories for souveniers.
