You're paying $2,000/yr into an account earning 3% interest compounded annually. What is the balance after 30 years? Think of it as a series of $2000 deposits, the first of which earns interest for 30 years, the 2nd for 29 years, etc.
The formula is A = PMT x [(1 + APR/n)(nY) - 1]/(APR/n) where A = accumulated balance, PMT is regular deposit amount, APR is annual percentage rate (decimal), n = no. of payment periods/yr, Y = no. of years.
A = 2000 x [1 + 0.03/1)1x30 - 1]/(0.03/1) ≅ $95,151
