Key takeaways
- The RBA has been cutting the cash rate in 2025, which means variable home loan interest rates have been falling.
- If you're on a variable rate home loan you can use Finder's calculator to see how much your repayments will fall by.
- As more rate cuts are announced lenders may not pass on the full cuts, so it's important to keep track of your rate changes.

How to use the rate cut calculator
Enter the following details into the calculator (or estimate them if you don't know):
- Select your repayment type. Most borrowers have principal-and-interest repayments. This means you're paying back the loan plus interest. If you're not sure, just select that option for now. If you have an interest-only loan you're just paying the interest charge every month but not actually repaying the loan yet.
- Enter your remaining loan amount. Check your latest home loan statement and see how much you have left to repay on your home loan.
- Enter your current interest rate. Again, your home loan statement should have your current interest rate.
- Enter your new rate. This is your current interest rate minus however much your lender is (or is expected to be) decreasing rates by (note: lenders don't always pass on the full rate cut, so check what your lender is doing). If your current rate is 6.00% and your lender is cutting rates by 25 basis points, then your new rate is 5.75%.
- Enter your remaining loan term. Most home loans have a 30-year term. Estimate how long you have left on your loan, to the nearest year.
12% say they've missed one or more mortgage repayments in the last 6 months. Almost a third of those people say it was down to interest rate increases.
What impact does a rate cut have on my loan?
Even a small decrease in interest rates can have a big impact on your monthly repayments. If you are able to though, keeping your monthly repayments at the same amount as before the rate cut will mean you pay off your home loan much faster.
The impact of a 0.25% cut on a home loan
The Reserve Bank of Australia (RBA) has been cutting interest rates this year. Cuts to the interest rate so far have been 0.25% each time.
Let's take a look at how much one cut could impact home loan repayments:
| Loan details | |
|---|---|
| Loan amount | $600,000 |
| Term | 30 years |
| Interest rate | 6.00% |
| Monthly repayment | $3,598 |
Now let's try that again with a 0.25% lower rate. Every other loan detail is the same.
| Loan details | |
|---|---|
| Loan amount | $600,000 |
| Term | 30 years |
| Interest rate | 5.75% |
| Monthly repayment | $3,502 |
Here we see that one rate cut of 25 basis points would save this borrower $96 a month. Over a year, that works out to $1,152 less. It saves you $34,512 in interest over the life of the loan. And that's just one rate cut.
