Getting Started

Our loan calculator is designed to help you understand your repayments and how strategies like extra repayments and offset accounts can save you thousands in interest.


1. Basic Loan Details

These are the foundational numbers for your loan calculation.

  • Interest Rate: The annual interest rate charged by your lender.
  • Loan Amount: The total amount you are borrowing or the current balance of your loan.
  • Loan Term: How long you have to pay back the loan (usually 25-30 years for mortgages).
  • Bank Repayment Cycle: How often your bank requires a payment (Weekly, Fortnightly, or Monthly).

2. Advanced Options: Offset & Extra Payments

This is where you can see the real power of financial planning.

  • Offset Balance: Money kept in a linked savings account that reduces the interest you pay on your loan.
  • Offset Cashflow: Track regular deposits (like salary) and expenses (living costs) to see their long-term impact.
  • Planned Repayments: Specify your actual repayment amount and frequency if you plan to pay more than the minimum.
  • Lumpsum Payments: One-off or recurring large payments that significantly reduce your interest over time.

Configuring offsets and extra repayments

Pro Tip: Why use an Offset?

Interest is calculated on your (Loan Balance - Offset Balance). By keeping more money in your offset, you pay less interest every day, which means more of your repayment goes towards paying off the principal!

After clicking "Calculate", you'll see a breakdown comparing your original loan with your new strategy.

  • Expected Total Interest: What you would have paid without any extra efforts.
  • Actual Interest Paid: The interest you'll pay given your offset balance and extra repayments.

  • Debt-free In: The actual time it will take to reach a zero balance.
