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

Refers to the interest rate before adjustments for inflation or other factors.

Effective Rate

The actual interest rate that borrowers pay or investors receive on a financial product, once all the compounding periods are factored in, often higher than the nominal rate.

Compounding Interval

The frequency at which interest is applied to the principal sum of a loan or deposit, affecting the total interest earned or paid.
