Frequently Asked Questions
How does the Commonwealth Bank Repayment Calculator work?
The calculator uses standard amortization formulas to compute monthly, fortnightly, or weekly repayments based on your loan amount, interest rate, and loan term. It creates a detailed schedule showing principal and interest portions of each payment.
Can I include extra repayments?
Yes, you can add extra repayments per period. Extra payments reduce the principal balance faster, saving interest and shortening the loan term.
How is the interest calculated?
Interest is calculated on the remaining principal balance using the compound interest formula. The annual rate is converted to the payment frequency (monthly, fortnightly, or weekly).
What’s the difference between Principal & Interest and Interest Only loans?
Principal & Interest loans include both principal and interest in each repayment, gradually paying off the loan. Interest Only loans only require interest payments, with the principal due at loan maturity.
Can I export the repayment schedule?
Yes, you can export your repayment schedule as PDF, Excel (XLSX), or CSV format for your records or financial planning.
