The home loan refinance calculator is a guide based on the information you have input. The results are not guaranteed and do not form part of a loan approval or guarantee to be eligible to refinance. Conditions apply to all loans and are subject to lender approval and assessment. Interest rates are a guide and may change on a daily basis. Final interest rates, savings and full terms and conditions and fees are in a lender’s loan offer after credit assessment.
