Your Mortgage Just Got More Expensive. Here's What You Should Do About It

Banks passed on the full rate hike today, adding $90-100 to monthly repayments. Here's the math, and your actual options.

Your Mortgage Just Got More Expensive. Here's What You Should Do About It
Key Points 2 min read
  • CBA raised variable rates 0.25% on March 27; fixed rates jumped 0.30%, with some owner-occupier loans now at 7.19%
  • For a $600,000 mortgage with 25 years remaining, expect an extra $90-100 per month in repayments
  • Mortgage stress risk now affects 26.6% of Australian borrowers (1.32 million); expected to hit 30.3% if rates rise again in May
  • Refinancing to fixed rates locks in costs but carries break fees; variable offers flexibility but exposure to further hikes
  • Check your loan terms, compare rates across lenders, and consider extra repayments if you can afford them

Your mortgage payment just went up. Commonwealth Bank confirmed this morning that variable rate home loans are rising by 0.25 percentage points, effective today, while fixed-rate products are climbing even faster at 0.30 percentage points. The big question for Australians with mortgages: what does this actually mean for your hip pocket, and what are your real options?

Here's the math. For someone carrying a typical $600,000 mortgage with 25 years left on the loan, today's changes add roughly $90 to $100 each month to repayments. That's $1,080 to $1,200 per year, before tax. And this isn't the end of it. The major banks are already predicting another 25 basis point rise in May, which would push the cash rate to 4.35 per cent and add even more to your bill.

The timing is sharp. The RBA itself raised the cash rate by a quarter point on March 17, and today the banks passed on the full amount. Some households are now looking at fixed-rate loans as high as 7.19 per cent for owner-occupiers, with investor loans reaching 7.04 per cent depending on loan-to-value ratio. If you're on a variable rate, your actual rate probably sits in the 5.5 to 7.0 per cent range, but it's heading up.

The household pain is real. Roy Morgan's latest data shows mortgage stress risk now affects 26.6 per cent of Australian borrowers across the country—that's 1.32 million people struggling to meet repayments. If rates rise again in May as predicted, that figure could reach 30.3 per cent, or 1.6 million Australians.

So what's your move? The honest answer depends on your situation. Fixed-rate loans lock in your costs for one to five years, which sounds safe, but they come with substantial break fees if you want to refinance, sell, or pay off early. Variable rates expose you to further hikes, but they preserve your flexibility and don't penalise you for switching lenders when better offers come along.

The smarter play is probably a review. Talk to your lender about what options exist within your current loan. Check whether you're paying a premium rate (some banks charge more than others for the same loan type). Track the RBA's decisions and forecasts so you know what's coming. If you can manage it, directing extra repayments toward principal now—even $50 extra per fortnight—saves you thousands in interest over the loan's life.

This isn't a short-term problem. The RBA has signalled a 'higher for longer' interest rate outlook, meaning relief isn't coming quickly. The question isn't whether rates will stay elevated; it's whether you can afford them. The next few months will tell you whether your household budget has room to move, or whether you need to think harder about your mortgage structure.
