Thanks for the guidance @adamsaghy. I am following the conversation jira.


Integer paymentPeriodsInOneYear = 0;
switch (repaymentFrequencyType) {
case DAYS:
paymentPeriodsInOneYear = 365;
paymentPeriodsInOneYear = interestRateFrequencyMethod.isMonthly() ? Integer.valueOf(360) : Integer.valueOf(365);

This looks weird to me. If why would it be 360 if it is monthly?

With monthly interest interest and daily repayments, it looks more reasonable to assume that there are exactly 360 days, a number divisible by the 12 months in the year brings our more explainable installments.

break;
case WEEKS:
paymentPeriodsInOneYear = 52;
paymentPeriodsInOneYear = interestRateFrequencyMethod.isMonthly() ? Integer.valueOf(48) : Integer.valueOf(52);

If the interest frequency is monthly, it looks more reasonable to assume there are four weeks in a month, so with 4 weeks in a month and 12 months in a year we shall have 4 x 12 = 48 weeks in a year.
