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 stated interest rate of a financial instrument or loan, not accounting for compounding or inflation.

Effective Rate

The interest rate on a loan or financial product, re-calculated annually, which takes into account the effect of compounding.

Compounding Interval

The frequency at which the earned interest is added to the principal balance of an investment, affecting the total compound interest over time.
