Home loan refinance calculator – estimate your savings
How to use the refinance calculator & understand your results
Refinancing a home loan in Australia can reduce monthly stress and unlock equity. Our mortgage refinance calculator simulates the effect of switching to a lower rate or changing your loan term. Enter your current loan details, new rate estimate, upfront costs (discharge, application, valuation) and property value to see LVR and break‑even point. If LVR exceeds 80%, you may face Lenders Mortgage Insurance (LMI) — a critical factor when refinancing.
Key metrics explained
- Monthly saving – reduction in repayment after refinance (based on new rate/term).
- Total interest saved – difference in total interest payable over the original remaining term, highlighting long-term benefit.
- Break-even months – upfront refinance costs divided by monthly savings. If you plan to stay beyond break-even, refinancing makes financial sense.
- LVR (Loan-to-Value Ratio) – loan balance ÷ property value. Australian lenders prefer LVR ≤80% to avoid LMI and secure competitive rates.
Australia refinance trends 2026 & smart timing
With cash rate signals and competitive lender offers, 2026 remains an opportune year to assess your mortgage. Many borrowers compare refinance home loan calculator tools to check whether a rate drop of 0.5%–0.9% justifies switching. Our unique refinance comparison calculator includes a break‑even indicator: for example, if refinance costs are $3,000 and monthly saving is $150, break‑even occurs in 20 months — excellent if you plan to hold the property longer.
Pro tip: Use our LVR calculator refinance to see if you have at least 20% equity. Improved LVR can unlock lower rates with major banks like Commbank, ANZ or Macquarie.
