So what you need to do here is to use the formula for compound interest.

That formula can be stated as

M = P(1+i)^n

In this formula, M is the final amount (the thing you are asking about here. P is the principal -- the original amount you invested. i is the interest rate and n is the number of compounding periods.

Please be sure to divide your interest rate by 4 before plugging it into the formula (assuming that the 5% is an annual interest rate).

So, in your case, we would have

M = 2000(1+.0125)^8

M = 2000 (1.0125)^8

M = 2000 (1.1044)

M = 2208.8

So your CD would be worth $2208.8
