Is this correct: find the geometric mean rate of increase. The question is a recent article suggested that if you earn $25,000 a year today and the inflation rate continues at 3 percent per year, you'll need to make $33,598 in 10 years to have the same buying power.

(33598/25000)^1/10 = 1.03 is this all I need to do.

It would probably be better written as:

33598 = 25000 * 1.03^10

But the 2 are the same equation rearranged a little (and correct by the way).
