Calculate the nominal and effective rate of interest for the following ordinary annuity. Determine the nominal interest rate whose compounding interval equals the payment interval.

Nominal Rate

The advertised or stated interest rate on a loan or investment, not accounting for any fees or compounding of interest.

Effective Rate

The real interest rate on an investment or loan, taking into account the effect of compounding over a given period.

Compounding Interval

The frequency at which interest is added to the principal amount of an investment or loan which can affect the total interest earned or paid.
