I presume you are a solo traveler, so you can cut down on a lot of costs by staying in hostels, BnB or even take rooms only on Air BnB. the total cost will depend on the number of days you planning to stay at each location. in France Paris and Niece are the popular choices and both these cities demand atleast 3 days each. Austria you have Vienna, Salzburg and Innsbruck. all these cities can be done with minimum of 2 nights each and as well in prague. Euro rail pass depending on the number of days of Flexi bus, can give you very good deals if you book in advance. I have us d Flexi bus, it's easy enough comfy. so if you can give the number of days and your choice of locations, may be I can be of better help. one this you would only need one visa i.e schengen visa, which you would need to apply in the country you land.
