Subject: compound daily interest
Name: sharon
Who are you: Student

calculate the return on $20,000 for 3 years at an interest rate of 8% that compounds daily.

Hi Sharon.

You do it: the formula is

B = P x (1 + R/N)TxN

where B is the balance at the end, P is the principal at the start, R is the annual rate of interest, N is the number of times per year the interest is compounded and T is the time in years. You want B and you have all the other variables, so plug them into your calculator and find the answer.

Hope this helps,
Stephen La Rocque.
