Loan Calculator

The Loan Calculator wizard models a loan before it is booked, computing the instalment, total interest and full amortisation schedule from inputs such as principal, rate, tenor, method and frequency. Officers use it to advise members and confirm affordability without creating a record.

Workflow

Open the calculator wizard.
Enter principal, interest rate, tenor and repayment frequency.
Select the interest method (flat or reducing balance).
Run to view the instalment and full schedule preview.
Share or use the figures to advise the member.
