How can I calculate the interest in advance and how much would the interest be per year?

If you request a loan, we will charge 5.66% interest in advance (6.0% effective annual interest rate). Loan interest is due on each policy anniversary. If you do not pay the interest when due, that interest will be added to the principal amount of the loan and bear interest at the same rate as the loan. You may repay all or part of a loan at any time while this policy is in force. You must identify any payment intended as a loan repayment, or it will be considered a premium payment. We will subtract any loan not repaid on the date of the insured's death from the death benefit. Jaime had a car that she drove until the wheels fell off. She is going off to college and needs a car. She will not be working too many hours while she is in college, so she wants to buy a car cash but is coming up short for cars she likes. She finds one for $6,000 and needs to take a loan out to buy it. How much would she pay if she repays it back within a year? What about if she pays it in 10 years
