💡 Accountant's Note
Mortgage repayments are split between interest (recognized as income) and principal reduction (reduces the loan balance). In early years of a mortgage, most of the payment is interest. The split is determined by the amortization schedule generated at origination.
Practitioner & Systems Framework
💻 ERP Architecture
In Oracle FLEXCUBE CL module, the system automatically generates the split based on the loan's amortization schedule (principal + interest). The schedule adjusts if the customer makes early repayments. In SAP CML, the repayment schedule is fixed at origination and deviations trigger a schedule recalculation.
⚠️ Audit Flags
Auditors test that the interest component matches the system-calculated amount based on the outstanding principal balance and the EIR. Any manual override of the principal/interest split requires dual authorization. CBJ requires that prepayment penalties (if charged) are disclosed in the loan agreement.
📄 Required Documentation
Loan repayment schedule, monthly account statement, system repayment allocation report, and customer payment receipt.
