Is that clear enough?
How much you spend depends on how you react to what you encounter.
Read the journals found at crazyguyonabike.com and you will get a good idea of what people spend when they are touring, including the unexpected or unusual costs which is what you seem to want.
The amount spent is a function of the attitude and approach of the person touring and it is different for each person.
The basics (food and lodging) are easy and you have acknowledged that. There is no way to "budget" for unexpected expenses because you don't know what they will consist of. This is even more true if you do not travel on the established bike routes such as Adventure Cycling. No offense to ACA intended, but the "adventure" is greater if you are not part of the endless stream of folks on those same few routes.
Try it. You'll like it.
