The Reserve Bank of Australia (RBA) has increased interest rates by 0.75% since February 2026, a significant change that affects many mortgage holders. For clients with a $750,000 mortgage on a variable rate, this rise has a direct impact on their weekly, fortnightly, and monthly repayments. Understanding how these changes affect your budget and what might happen if rates rise again is essential for managing your mortgage effectively this year.
How the Interest Rate Rise Affects Mortgage Repayments
At the start of 2026, the average variable interest rate was approximately 5.29%. Since February, the RBA has increased rates by 0.75%, pushing the current average variable rate to about 6.04%. For a $750,000 mortgage, this increase translates into higher repayments.
Repayment Comparison
Here’s a breakdown of repayments before and after the rate increase, assuming a 30-year loan term:
| Repayment Frequency | At 5.29% Interest | At 6.04% Interest | Increase in Repayment |
| Weekly $682 $736 +$54 | Fortnightly $1,364 $1,472 +$108
| Monthly $2,955 $3,190 +$235
What this means:
Since February, clients have been paying an extra $54 weekly, $108 fortnightly, or $235 monthly. Over a year, this adds up to thousands of dollars more in interest payments.
What Happens If Interest Rates Rise Again?
The RBA has signaled the possibility of further rate increases this year. Let’s explore the impact of one or two additional 0.25% rises on repayments.
Scenario 1: One More 0.25% Increase (6.29% Interest Rate)
| Repayment Frequency | New Repayment | Increase from 6.04% |
| Weekly $767 +$31 | Fortnightly $1,534 +$62
| Monthly $3,324 +$134
Scenario 2: Two More 0.25% Increases (6.54% Interest Rate)
| Repayment Frequency | New Repayment | Increase from 6.04% |
| Weekly $799 +$63
| Fortnightly $1,598 +$126
| Monthly $3,474 +$284
Each additional increase adds pressure to household budgets. Clients should prepare for these possibilities by reviewing their finances and considering options such as refinancing or adjusting repayment schedules.
Strategies to Manage Rising Mortgage Costs
Facing higher repayments can be challenging, but there are practical steps to ease the impact:
Review your budget: Identify areas to reduce discretionary spending.
Consider making extra repayments: When possible, this reduces the loan principal and interest over time.
Talk to your mortgage broker: They can help explore refinancing options or switching to a fixed rate if it suits your situation.
Set up an offset account: This can reduce the interest charged on your mortgage.
Stay informed: Keep an eye on RBA announcements and market trends.
Why Understanding Your Repayments Matters
Knowing exactly how interest rate changes affect your repayments helps you plan better. It avoids surprises and gives you control over your financial future. For a $750,000 mortgage, even small rate changes can mean significant differences in what you pay each month.
