Financial Stress Test Calculator

Find Your Vulnerability to the 5 Future Shocks
A financial stress test calculator shows how well your budget would hold up if costs rise or income is hit. The ICM Hub 5 Future Shocks Assessment tests your position against five pressures: fuel and energy, climate, inflation and rates, mortgage stress and AI. It gives you a threat level for each shock and an action plan, so you know where you're exposed before the pressure arrives.

Most households can name the shocks. Few know which one would hurt them most. This tool puts your own numbers against each threat, so your plan rests on your budget and not on a headline.

What Is a Financial Stress Test Calculator and What Are the 5 Future Shocks?

A financial stress test calculator applies realistic pressures to your income, loan and living costs, then shows how much room you have left. The 5 Future Shocks Assessment is an interactive tool on the ICM Hub. It scores your vulnerability to five separate threats and combines them into one readiness picture.

The 5 Future Shocks are fuel and energy costs, climate impacts, inflation and interest rates, mortgage stress, and AI disruption to your income. Each one reaches your finances in a different way, and each one can be tested on its own.

  • Fuel and Energy. The cost of petrol and diesel in your monthly budget, plus increases in power, gas and general energy bills.
  • Climate. The effect of extreme weather on property insurance, living conditions and the general cost of living.
  • Inflation and Rates. Ongoing price pressure on everyday goods and the lasting effect of changing interest rates on your budget.
  • Mortgage Stress. Your mortgage-to-income ratio, measured against the stress benchmark of 35%.
  • AI and Job Income. The potential disruption of your industry by artificial intelligence and what it could mean for your long-term earning capacity.

The tool is built for homeowners, buyers and investors who want to see their weak spots early. It suits you if you're about to borrow, if your fixed rate is ending, or if you simply want to know how much shock your budget can take.

5 Shocks

How Do You Stress Test Your Finances Against the 5 Shocks?

You stress test your finances by entering your income, loan and main living costs, then checking your result against each of the five shocks. The assessment shows where you're comfortable and where you're exposed. Run it more than once to see how a change in one shock moves the others.

Here's the process:

  1. Open the 5 Future Shocks Assessment in your ICM Hub account.
  2. Enter your household income, loan balance, interest rate and repayment.
  3. Add your main running costs, including fuel, energy and insurance.
  4. Tell the tool about your work or industry, so it can gauge AI exposure.
  5. Review your threat level for each of the five shocks.
  6. Read your action plan and note the shock with the highest threat.
  7. Change one input, for example a higher rate, and see how your levels move.

A worked example

Take a household earning $150,000 a year before tax, with a $600,000 loan over 30 years. At a 6.0% rate, repayments come to roughly $3,597 a month, or about $43,170 a year. That's about 28.8% of income, under the 35% benchmark. If the rate rises to 7.0%, repayments climb to roughly $3,992 a month and the ratio reaches about 31.9%. At 8.0%, repayments are roughly $4,403 a month and the ratio passes the benchmark at about 35.2%.

On a $600,000 loan over 30 years, a household earning $150,000 crosses the 35% mortgage stress benchmark when the rate climbs from 6.0% to about 8.0%.

Now add the other shocks. A few hundred dollars more a year on fuel, a higher home insurance premium and rising grocery bills all sit on top of that repayment. That's why the tool tests the shocks together as well as alone. The figures here are hypothetical, not current market rates. Enter your own numbers to see your own result.

Financial Security

Why Do These 5 Shocks Matter to Your Financial Security?

These shocks matter because each one raises your costs or threatens your income, and they often arrive together. A household that can absorb one shock may struggle with two. Knowing your threat level for each lets you act on the weakest point first.

Recent data shows the pressure is real and current.
Mortgage stress is the shock most households can measure today, because it needs only your income, your loan and your rate. The other four shocks take a little more estimating, which is why the assessment guides you through them.

For a wider view of your finances, our loan health check compares your current loan against the market. If you're also weighing a loan's rate type, the Fix or Float Calculator shows how repayments change under different rate paths.
Future Shocks Compared

The 5 Future Shocks Compared: Which Threat Hits Hardest?

The threat that hits hardest depends on your situation. A borrower with a large loan feels rates and mortgage stress first. A long-distance commuter feels fuel first. A homeowner in a storm-prone area feels climate and insurance first. A worker in a routine office role has more reason to watch AI.
Shock What it hits How fast it acts Who feels it most Your main lever
Fuel and Energy Monthly running costs Fast, often within weeks Commuters, large households Usage, plans, efficiency
Climate Insurance, repairs, relocation Slow build, sudden events Owners in high-risk areas Cover, location, resilience
Inflation and Rates Repayments and daily costs Moderate, month to month Borrowers, variable-rate holders Rate structure, refinance
Mortgage Stress Share of income spent on the loan Triggered by rate or income change High loan-to-income households Loan size, term, buffer
AI and Job Income Long-term earning capacity Gradual, uneven by industry Routine cognitive roles Skills, savings, diversification

The 5 Future Shocks differ in speed and scale: fuel acts in weeks, mortgage stress follows a rate rise within a month, and AI works over years.

Terms and exposure differ by household, so use the table as a guide and not a verdict. Our refinancing team can review your loan structure if the assessment flags rates or mortgage stress as your top threat.

When to run the assessment

Run it before you borrow, before your fixed term ends, after a rate change, and when your income or household changes. A yearly check is a reasonable minimum. If you're planning to buy, pair it with the Buying Costs Calculator so you see the full cost of the purchase.

Mistakes to avoid when stress testing

Don't test only your current rate. Test a rate higher than today's. Don't ignore the small shocks either, because fuel, energy and insurance together can equal a rate rise. And don't treat a low threat level as permanent. Your result is a snapshot, and it changes when your income, loan or costs change.

Stress Benchmark

What Is the 35% Mortgage Stress Benchmark and Where Do You Sit?

The 35% benchmark is the point where your loan repayments take more than 35% of your income, which signals mortgage stress. The Hub uses it as the line between a comfortable position and a vulnerable one. The closer you get to 35%, the less room you have for any other shock.

Mortgage stress isn't a single official measure. Other bodies use different thresholds and income definitions. Roy Morgan, for example, flags a household as at risk when repayments exceed a share of after-tax income that ranges from 25% to 45% depending on income and spending. The ICM Hub uses a clear 35% line so you can compare your own ratio against one consistent number.

Here's how to read your ratio:

  • Under 30%. You have a healthy buffer. Keep testing, especially if you're on a variable rate.
  • 30% to 35%. You're close to the line. A rate rise or a jump in living costs could push you over.
  • Above 35%. You're in the stress zone. Review your loan, your costs and your buffer soon.

What Does Each Shock Cost a Typical Household?

Each shock adds a different cost, and none of them is fixed. The figures below are examples built from public data, not forecasts. They show the scale, so you can compare it with your own budget.

  • Fuel and Energy. If you fill a 50 litre tank once a week, a 20 cent rise in the price per litre adds about $520 a year. Higher power and gas bills add to that.
  • Climate. The average home and contents premium was $2,795 in 2025, according to Canstar. A 14% rise adds roughly $390 a year, and uninsured damage costs far more.
  • Inflation and Rates. On a $600,000 loan over 30 years, a one point rate rise adds about $395 a month. Everyday goods then cost more on top.
  • Mortgage Stress. Crossing 35% of income leaves less for savings, repairs and emergencies, which makes every other shock harder to absorb.
  • AI and Job Income. The cost is the hardest to estimate. It could be slower pay growth, a career change or retraining time, so the tool asks about your industry.

A one percentage point rise on a $600,000 loan costs about $395 a month, or roughly $4,740 a year, many times the yearly cost of a 20 cent fuel increase.

Reviewing Their Position

What Have Clients Done After Reviewing Their Position?

Clients who review their finances early often find savings and breathing room, and a review is usually the quickest way to lower exposure to rates and mortgage stress. One story from Investors Choice Mortgages shows the scale of what's possible.

Sarah K. from Melbourne refinanced and released equity, saving $340 a month with a three-week turnaround. Lower repayments mean a lower mortgage-to-income ratio, which is exactly what the assessment helps you aim for.

Each situation is different, and rates, fees and lender policies change often. Use the assessment to find your weak points and a broker to compare live options.

Common Questions

Frequently Asked Questions About Rental Yield

What are the 5 Future Shocks?

The 5 Future Shocks are fuel and energy costs, climate impacts, inflation and interest rates, mortgage stress, and AI disruption to your income. The ICM Hub assessment scores your vulnerability to each and gives you an action plan.

What is a financial stress test calculator?

It's a tool that applies pressures such as higher rates or living costs to your income and loan, then shows how much room your budget has. The ICM Hub 5 Future Shocks Assessment tests five pressures at once.

What is the 35% mortgage stress benchmark?

It's the point where mortgage repayments take more than 35% of your income. Above it, you have less room to absorb other costs. The Hub assessment measures your mortgage-to-income ratio against this benchmark.

How do rising interest rates affect my mortgage stress?

A higher rate lifts your repayment, which raises the share of income going to your loan. On a $600,000 loan over 30 years, a one point rise adds about $395 a month. The assessment shows where that would put you.

Will AI take my job?

Nobody can say for certain. Australian government research found no sign of mass AI job losses, but employment grew more slowly in the most AI-exposed occupations. The assessment asks about your industry to estimate your exposure.

How does climate risk affect my finances?

Extreme weather can raise your home insurance premium, add repair costs and affect living conditions. Premiums for home and contents cover in the largest cities rose an average of 14.78% in the year to June 2026.

How often should I run the assessment?

At least once a year, and whenever your income, loan or household changes. Run it before you borrow, before a fixed rate ends and after any rate change, because your threat levels move with your situation.

Is the 5 Future Shocks Assessment free to use?

The Hub has a free account level, and some tools unlock when you become a client. Create your free account to see which calculators are open to you.
