Mortgage Stress Calculator
Do you own the house by yourself or jointly with someone?

Our calculator estimates your risk of mortgage stress by taking the following steps:

  • Breaking down any entered annual income(s) into approximate monthly income by dividing the total by 12.
  • Calculating approximate income tax and deducting from annual income to determine approximate disposable income.
  • Calculating your monthly loan repayments based on your interest rate, total loan and years remaining.
  • Comparing the approximate monthly repayment to your approximate monthly income (yours plus you partner’s).
  • Displaying the result as a percentage on the table – results higher than 30 per cent are assumed to be in mortgage stress.
  • All calculations are estimates – they are not guarantees that you’ll be able to afford a particular home loan repayment and are not pre-qualifications or pre-approvals for borrowing.
  • These calculations are only accurate for the information entered, and do not take into account future changes to you/your partner’s income, your home loan interest rate, or your mortgage repayments.
  • Different lenders may use different serviceability criteria to measure the risk of mortgage stress when you apply for a home loan.
  • Results are calculated based on pre-tax income and do not take any other living expenses into account.
  • Some people on high incomes may be comfortable paying 30% or more on housing or some people may have a solid buffer or back-up plan to make them comfortable taking on a larger debt.
  • The calculator is for information purposes only. Any advice is general and has not taken into account your personal circumstances.

What does it cost to use Mortgage Stress Calculator?

Using Mortgage Stress Calculator costs you nothing. That’s the same as when you use a Mortgage Broker to manage your home loan process for you.

Brokers are paid directly from the bank when you get unconditional approval on your loan.

What they get paid varies. As an example, if you were to borrow $400,000 the lender would pay $2,200 assuming a 0.55% commission. We believe in being fully transparent.

Remember, using us doesn’t cost you anything extra, and you don’t pay a higher interest rate or any extra fees on the loan if you use a broker to help find a better rate.

What's that?

LVR, LMI, Comparison rate, interest only, conveyancing and more! When we were researching our home loan options, we kept seeing all this jargon everywhere. Everyone else seemed to know what LMI meant but we…erm.. weren’t so clear. Here are some straight up definitions for people like us that like their answers without a side of gobbledygook.

LMI stands for Lender’s Mortgage Insurance. This protects the bank in case you default on your home loan. This is an additional charge, typically if your deposit is less than 20% of the purchase price. If you want to buy a property for $500,000 and have $50,000 (10%) saved for a deposit, the bank may charge you LMI. LMI is a once-off payment, and can often be added to your loan amount.

LVR stands for Loan to Value Ratio. The amount of money that a bank will lend you based on how much the property is worth. For example, an 80% LVR means the bank is willing to lend up to 80% of what the property is worth. If you’re buying a property for $500,000, an 80% LVR loan is $400,000. In this example, you would need to have $100,000 (20% of $500,000) saved up for a deposit.

Absolutely not. When applying for a home loan a mortgage broker can often get you better rates than what you could by going directly to your bank. First, they get some info, do lots more research and then they’ll show you the lowest rates from a range of lenders. Then, they’ll negotiate with the bank to ensure you get the best rate possible. This service costs you nothing and you might even end up paying a lot less than nothing – if you get a cashback or or secure a lower rate, or both!?

You might incur break costs  if you repay a fixed rate interest loan before the end of the fixed interest period or if you make extra repayments that exceed the maximum allowed on your loan. If you do want to repay your loan in full, you can ask your lender for a quote on current break costs to see how much extra you might be charged.

Lenders often use rebates or cash back as an incentive to refinance with them. Cash back gives you a refund once you’ve taken out your loan, while a rebate is a reduction in the balance of the loan. It’s wise to compare all other interest charges, comparison rates and fees to make sure it’s a good deal.

A comparison rate factors in all costs associated with a loan, including the interest rate, fees and charges. It helps you understand the true cost of a loan and more easily compare with loans from different lenders, so you can estimate how much you might pay over the life of the loan. It is represented by a single percentage rate which factors-in the interest rate, fees and charges relating to the loan. (Government charges or early pay out fees are excluded).
