I didn't think about all this until I was well into my 3rd year...
but anyway, a bit of background, if you start work at a chartered firm, you'll have to work for 6 months minimum (to gain relevant experience) before you can start the CA program...if all goes to plan (i.e. you pass all the subjects first go), you'll finish the program in about 2 years, but to become a registered CA, you need min. 3 years work experience, by that stage you'd be a Senior Accountant/Consultant/whatever
In terms of salary, unless you leave your chartered firm and move into industry, you won't see any jump in your pay other than the normal promotion cycle.
There are no standard wages, and in 6/7 years time (when you'll be a CA), who knows what the economy/job market will be like?
