Answer:
The new price of the bond is $928.94
Explanation:
Initially the bond's price is equal to its par value which means the coupon rate on bond and the market interest rates are the same i.e. 6%.
Th bond's price is calculated as the sum of the present value of the annuity of interest payments by the bond and the present value of the face value of the bond that will be received at maturity. The discount rate used to calculate the present values is the market interest rate.
As the bond is a semiannual bond, we will use the semi annual coupon payment, the semi annual percentage of the annual rate of interest on market and the number of semi annual periods outstanding.
Semi annual coupon payment = 1000 * 0.06 * 6/12 = $30
Number of semiannual periods till maturity = 10 * 2 = 20 periods
New market interest rate = 6 + 1 = 7% annual
New semi annual market interest rate = 7% / 2 = 3.5%
Price of bond = 30 * [ (1 - (1+0.035)^-20) / 0.035 ] + 1000 / (1+0.035)^20
Price of bond = $928.938 rounded off to $928.94
We used the present value of annuity ordinary formula for preset value of interest payments and the normal present value of principal formula for the face value.
My answer -
it determines how much
they charge you in interest if you carry a balance. Lower is better.
The percentage interest is what they charge you each month, “annual
percentage rate” is what you’re paying if you keep that balance for a
year. It’s slightly different because in that year, you’re also paying
interest on the amount of interest (compound interest) you owe in the
previous months.
Not carrying a balance means that you don’t pay interest.
