The annual effective rate of insurance referred to in article L. 313-8 is equal to the difference between:
1° The annual percentage rate of charge defined in article L. 314-1, calculated in accordance with articles R. 314-1 to R. 314-10 on the assumption that the insurance proposed for the purpose of repaying the credit is fully required by the lender, on the one hand, and;
2° The annual percentage rate of charge defined in Article L. 314-1, calculated in accordance with Articles R. 314-1 to R. 314-10 on the assumption that no insurance is required by the lender, on the other hand.
For the purposes of calculating the annual effective rate of insurance, the method used is the same as that used to calculate the annual effective global rate, i.e. either the discounted cash flow method or the compound interest method by capitalising the periodic rate over a period of one year.
