Common questions about refinancing and your options

If you’re exploring whether refinancing could be right for you, these quick answers cover some of the things people often want to understand first.

  • To use this refinance calculator, you’ll need a few key details about your current loan. This includes your current loan balance, property value, interest rate, remaining term and repayment amount. Having this information ready can help you get a more useful estimate and better understand how your repayments could change.

  • This refinance calculator estimates how much you may save by comparing your current loan with a select NAB home loan. It looks at changes to your interest rate, repayments and total interest over time. Depending on the difference between your existing loan terms and the terms of the selected NAB home loan, your savings could range from lower monthly repayments to thousands of dollars saved in interest. While the results are an estimate, they can help you gauge whether refinancing may reduce your overall costs.

  • There isn’t a set limit on how often you can refinance a home loan. However, there may be an impact to your credit score because each time you apply to refinance, a lender may check your credit information as part of their credit assessment process.

    A refinance calculator can help you sense-check your options before you take the next step to refinance.
