How to Charge Interest and Fixed Charges to Customers Debtors Account using the Interest Charging Utility


How Interest Is Calculated

The Interest Charge is calculated by applying the annual interest rate percentage to the specified balance, then dividing this value by 365 days and multiplying it by the number of days to be charged.  To this added any Fixed Charge and GST.

Overdue Amount / 365 Days x Days Interest Charged x Interest Rate = Interest Charged


So I have charged Plant Hire Ltd Interest on their outstanding balance of $1029.05 so how was this 5% Interest Calculated?

1029.05 / 365 (days) = 2.82 

2.82 x 31 (days interest charged) = 87.42 

87.42 x 5% (Interest Rate Charged ) = 4.37

4.37 is amount of Interest to be charged to Customer
