use one of the formulas below to determine how much you should deposit at the end of every six months.

You should deposit $453.83 at the end of every 6-month period for 4 years or 8 semi-annual periods.

$453.83 x 8 =$3,630.64 - This is total principal you must deposit.

$4,000 - $3,630.64 = $369.36 - This is the interest earned on the investment.
