How the cash rate flows through to your mortgage
The cash rate is the interest rate on overnight loans between banks, set by the Reserve Bank of Australia (currently 4.85%). It sets the base cost of money for lenders, so when it moves, banks usually move their variable home loan rates by the same amount within a week or two.
Your own rate is higher than the cash rate because it includes the lender's margin. A 0.25 point change in the cash rate usually means a 0.25 point change to your variable rate, not a 0.25% change in your repayment. The repayment changes more or less depending on your balance and how long is left on the loan.
Worked example: $600,000 owing, 25 years left
A borrower owes $600,000 on a variable principal-and-interest loan at 6.24% with 25 years remaining. The RBA raises the cash rate by 0.25 points and the lender passes on the full rise.
- Rate before
- 6.24%
- Rate after
- 6.49%
- Monthly repayment before
- $3,954.31
- Monthly repayment after
- $4,047.49
- Extra each year
- $1,118
- Extra each month
- $93.19
If the higher rate held for all 25 years, the borrower would pay about $27,956 more in interest. Rates rarely stay put that long, but it shows how much a small move adds up.
Common mistakes
Assuming fixed loans change straight away
Fixed-rate loans keep their rate until the fixed term ends. The change hits when you roll onto a variable rate.
Waiting for the lender to cut your repayment
Some lenders keep your repayment the same after a cut unless you ask. Keeping it higher pays the loan off faster, but check what yours does.
Forgetting your offset account
Interest is charged on the balance minus your offset, so enter your balance net of offset savings for a closer figure.
Only comparing against your own lender
Lenders don't always pass on the full change, and new-customer rates are often lower. A rate move is a good prompt to compare.
