When you apply for a home loan, banks won’t simply assess your borrowing capacity based on their standard variable rate.
They will actually assess you at a higher “floor” rate as a way of mitigating their risk if interest rates were to suddenly rise.
This can have a serious impact on your ability to borrow the amount you need but not all lenders apply the same serviceability rules.
How does the assessment rate work?
First of all, decisions on bank Standard Variable Rates (SVR) are driven by changes to the the Reserve Bank of Australia (RBA) cash rate.
The bank will then normally add an extra 2-3 percentage points to the official cash rate in order to arrive at their SVR.
This is to cover their cost of funding the loan plus a margin so they can earn a profit.
Obviously, the risks associated with your application will also determine the margin applied to your interest rate.
When assessing your ability to afford your home loan repayments or “serviceability”, most lenders will also add an extra buffer known as a benchmark assessment rate or floor rate.
This will typically be 2-3% above the bank’s SVR and it’s applied when assessing a customer’s income and asset position for serviceability.
The reason that the assessment rate is applied is to determine whether you could still make your mortgage repayments in the event that interest rates were to rise.
Think of it like an earthquake test for your financial situation.
Banks don’t publish their assessment rates!
Assessment rates or floor rates aren’t known to the general public so it can be very easy for applicants to fail the bank’s serviceability test.
That’s because banks don’t advertise them!
With the recent changes, we know that some banks are using a floor assessement rate as low as 5.30% (Previously, most banks used 7.25%).
While, some lenders like ING who’ve been historically conservative are still using an assessment floor rate of 8%. This is unlikely to change.

What has changed?
In July 2019, APRA (Australian Prudential Regulation Authority) finalised the following changes:
- Removed the previously mandated 7% serviceability floor rate. Banks are now free to set their own minimum floor assessment rate.
- Increased the buffer rate that’s applied to your home loan rate to 2.5% from 2%.
This means, lenders will now use the higher of the two rate – either the minimum floor rate or your interest rate plus the 2.5% buffer to assess your application.
With interest rate at record lows, you could easily be assessed at 6% (3.25% plus a 2.5% buffer) instead of the previous uniform floor rate of 7.25%.
This is a major boost to the maximum borrowing power of borrowers with:
- First home buyers seeing their borrowing power increase by as much 15% approximately.
- Investors can now borrow 15% – 30% more than they could before.
Why did APRA make these changes?
In December 2014, APRA cracked down on banks and lenders regarding how they assessed someone for a home loan.
They essentially did this to “limit excessive borrowing in an environment of low interest rates and high debt”.
- With record low interest rates which are expected to persist, the difference between the actual rates paid by home loan borrowers and the floor rate had become unnecessarily wide. For example, when current interest rates are as low 3%, it doesnt make sense for them to be assessed at 7.25%.
- Back then, banks used a single variable rate as the basis for all home loans. Since then, lenders have introduced different pricing for different mortgage products. A single floor rate for both owner-occupiers paying principal and interest repayment and investors with interest only repayments doesn’t make sense.
How much more can I borrow now?
Under the new system, a single borrower with an income of $80,000 p.a. with no dependents and standard living expenses while being assessed at 7.25% could borrow upto $498,404 with a 30-year mortgage.
Now, when the same borrower is assessed at an assessment rate 6%, he/she can borrow up to $567,091.
That’s an increase of $68,687 or roughly 14% in their borrowing power.
The borrowing power calculation will be different for everyone as they are complex and have a lot of variable factors.
Not all lenders are the same!
Not all lenders have the same serviceability test and apply the same floor rate buffer!
The big difference is for property investors since your existing debts may actually be assessed using an even higher assessment rate.
Where the actual interest rate is used to assess your serviceability, you can borrow more.
So which lenders don’t use a floor rate?
The rules around assessment rates only apply to ADIs like banks and certain major lenders.
There are a number of non-bank lenders that won’t necessarily apply a floor rate when assessing your application.
That’s because they don’t fall under the jurisdiction of APRA.
Floor rate mortgage case study
Jeremy and Linda are both high school teachers earning $70,000.
They need a $500,000 home loan to buy their very first home.
They currently have a credit card with a $20,000 limit and they’re paying $488 a month for a $25,000 car loan.
Other than that, they’re debt-free and feel like they’re in a position to borrow the amount they need.
Their bank is offering a competitive variable interest rate of 3.69% so they decide to apply.
Based on that interest rate and loan amount, their actual monthly repayments will be around $2,299.
However, when assessing their application, the bank applies a floor rate, bringing the couple’s assessment rate to 7.85%.
Effectively, the bank wants to know if they can afford to make their mortgage repayments when paying $3,617 a month.
That’s the same as borrowing $800,000 over 30 years when they’re only wanting to borrow $500,000!
Because the floor rate has been applied, Jeremy and Linda are declined by their bank.
However, the couple are currently using much less than their $20,000 credit limit allows them.
If they were to pay down their credit card and reduce their limit to $10,000, they would be able to qualify for their $500,000 home loan.
How do I work out my borrowing power?
There are three different methods that lenders use to calculate your serviceability:
- Net Surplus Ratio (NSR).
- Debt Servicing Ratio (DSR).
- Surplus / Uncommitted Monthly Income (UMI).
They differ in how they weigh up your income and expenses, and the way they display the result.
The DSR method was commonly used in the past but it’s now considered to be inaccurate for property investors or for people earning over $200,000 or under $30,000.
