CBA Home Loan Calculator
Buying a home is one of the biggest financial decisions you’ll make. Understanding how much your home loan repayments will be, how interest accrues, and how offset accounts can save you money is crucial. The CBA Home Loan Calculator is designed to help you calculate repayments for any loan amount, interest rate, and term, allowing you to make informed decisions.
Whether you’re planning to pay monthly, fortnightly, or weekly, this tool provides accurate repayment estimates, total interest payable, and savings from offset accounts.
How the CBA Home Loan Calculator Works
The calculator takes several key inputs:
- Loan Amount – The total principal of your home loan.
- Interest Rate (% per year) – Annual interest rate applied to the loan.
- Loan Term (Years) – Number of years over which you plan to repay the loan.
- Repayment Type – Choose between Principal & Interest or Interest Only repayments.
- Payment Frequency – Weekly, fortnightly, or monthly payments.
- Offset Account Balance – Money in an offset account that reduces interest on your loan.
It calculates:
- Estimated Repayments – Payment amount per selected frequency.
- Effective Loan Amount – Loan minus offset account balance.
- Total Repayments – Sum of all repayments over the loan term.
- Total Interest Paid – Total interest charged over the life of the loan.
- Interest Saved (Offset) – How much the offset account reduces interest costs.
