Gladstone QLD mortgage refinancing calculator
Compare what you are paying now against what a switch would look like, with the switching costs taken off the result rather than left out of it.
Example rate used: 6.50% p.a. for owner-occupiers, set on 27 July 2026. It is an assumption so the calculator can return a figure, not a lender quote, not an offer and not a rate you are eligible for. Rates change without notice, and the rate you are offered varies by lender, loan type, deposit and credit profile. Put your own rate in the field to see your own numbers. Both rate fields start on that same example rate, so the comparison shows nothing until you enter your real current rate and the rate you are considering.

Fill in your current loan and the rate you are considering, then select calculate. You will get the repayment difference, the break even point and the total interest on both sides.
Is switching actually worth it on your file?
The number that matters is not the advertised rate, it is whether a lender will take your loan at that rate once your income, equity and credit history are on the table. That is the part Coral checks before you pay a discharge fee.

What a rate drop is actually worth after costs
Switching costs money before it saves any. Discharge fees, an application fee and a valuation typically come to around $2,500, and that has to be earned back before you are ahead. On a $400,000 balance with 20 years left at 6.50%, keeping the same 20 year term, this is where each rate lands.
| New rate | Monthly saving | Break even | Interest difference | Net position after costs |
|---|---|---|---|---|
| 6.50% (no change) | Nil | Never | Nil | $2,500 behind |
| 6.25% | $59 | 3.6 years | $14,059 | $11,559 ahead |
| 6.00% | $117 | 1.8 years | $27,976 | $25,476 ahead |
| 5.75% | $174 | 1.2 years | $41,750 | $39,250 ahead |
| 5.50% | $231 | 0.9 years | $55,378 | $52,878 ahead |
| 5.25% | $287 | 0.7 years | $68,860 | $66,360 ahead |
Only one thing: how long the lower repayment takes to repay the switching fees. It says nothing about what the loan costs over its life. A switch can break even in four months and still leave you worse off, which is what the next table is about.
What resetting the term back to 30 years really costs
The most common way a refinance goes wrong is not the rate, it is the term. Twenty years into a loan, taking a new 30 year term stretches the remaining balance back out. The repayment falls, which feels like a win, and the total interest climbs past what you were going to pay anyway. Same $400,000 balance, same 5.75% rate, only the term changes.
| New term | Monthly repayment | Change per month | Total interest | Net position after costs |
|---|---|---|---|---|
| Staying put, 20 years at 6.50% | $2,982 | Baseline | $315,750 | Baseline |
| 15 years | $3,322 | $339 more | $197,895 | $115,355 ahead |
| 20 years | $2,808 | $174 less | $274,000 | $39,250 ahead |
| 25 years | $2,516 | $466 less | $354,928 | $41,677 behind |
| 30 years | $2,334 | $648 less | $440,345 | $127,095 behind |
$648 a month lighter, $127,095 worse off
Both are true at the same time. If cash flow is the actual problem then a longer term may still be the right answer, but it should be a decision you made rather than a side effect you did not notice.
When refinancing is worth doing
A lower rate is the reason people give. It is rarely the only one on the table, and sometimes it is not the one that matters most.
-
The rate gap has widened
Loans drift. A rate that was sharp three years ago may not be now, particularly if you have been with the same lender since before your last fixed period ended.
-
Your LVR has dropped under 80%
Between the principal you have repaid and any growth in the property, you may now be under the 80% threshold. That opens lenders and pricing that were closed to you at the time you borrowed.
-
You want to consolidate other debt
Rolling higher rate debt into the mortgage lowers the rate on it and lengthens the term, so it can cost more overall while helping monthly. Worth modelling both ways before committing.
-
You want to release equity
For a renovation, a deposit on an investment property, or a business purpose. That is a different application to a straight rate switch, with its own assessment.
-
The loan structure no longer fits
An offset account, a split between fixed and variable, or the ability to make extra repayments without a cap. Structure is often worth more over a loan life than a small rate difference.
-
A fixed period is ending
Rolling onto a lender’s revert rate without checking it is one of the more expensive things a borrower can do quietly. The month before a fixed term ends is the time to look.
What actually happens when you refinance
Start to finish this usually runs four to six weeks, most of which is the two lenders talking to each other rather than anything you need to do.
- 1
Work out whether the numbers survive the costs
That is the calculator above. Put in your real balance, your real remaining term and the rate you are being offered, not the headline rate in the advertisement.
- 2
Check what your current lender will do first
A discharge request often produces a retention offer. Sometimes it matches what you were leaving for, which saves you the switch entirely. It costs one phone call to find out.
- 3
Confirm your position will assess
Income, existing commitments, credit history and the property itself all get reassessed as if it were a new loan. Being an existing borrower somewhere else counts for nothing at the new lender.
- 4
Get the property valued
The new lender orders its own valuation, and that figure sets your LVR at the new lender, not what you believe the property is worth. A valuation under expectation is the most common reason a refinance stalls.
- 5
Settle and discharge
The new lender pays out the old one and the mortgage is transferred. Your repayment date, direct debits and any offset arrangements change over, which is worth checking in the first month rather than assuming.
Refinancing questions we get asked in Gladstone
The calculator defaults to $2,500, which typically covers a discharge fee from the outgoing lender, an application or settlement fee at the incoming one, and a valuation. Some lenders waive parts of it. A fixed rate loan broken early can add a break cost that dwarfs all of it, so that needs checking first.
