03
Explore the scenario
Use What-If to see how changes to income, expenses or savings could affect your household’s resilience.
FAQ
A few common questions about what the test does — and what it doesn’t.
Use the income your household actually receives after deductions — the amount available to pay for everyday expenses, bills and savings. Include regular income you reasonably expect to receive each month.
Include the regular expenses your household would still need to pay if income fell — such as housing, food, utilities, transport, insurance, healthcare, childcare and minimum debt repayments. Leave out spending you could reasonably pause or reduce.
Include savings you could realistically use to cover household expenses if income fell. This might include cash and money in accessible savings accounts. Avoid counting money that is locked away, difficult to access or intended for another purpose unless you would genuinely use it in this situation.
The test is designed around a simple question: what happens if part of your household income suddenly stops? By removing that income and comparing what remains with your essential expenses, the test gives you a clearer view of how your household might cope.
No. The result is a simple stress-test indicator, not a judgement of your household’s overall financial health. Real life can involve many factors the test does not capture, including changing expenses, insurance, government support, investments and other sources of help.
The One-Income Stress Test is designed to perform its calculations in your browser rather than sending your household figures to The Pocket Umbrella for storage. Please avoid entering sensitive personal information such as names, identification numbers, account numbers or passwords.
Methodology & Assumptions
A simple stress test, not a prediction.
The test compares the income your household would have left if part of it disappeared with the essential expenses you would still need to cover. Accessible savings are then used to estimate how long a monthly shortfall could be sustained.
How the test calculates your result
Remaining income
Take-home income − Income that could disappear
Monthly gap
Essential expenses − Remaining income
If your remaining income covers your essential expenses, there is no monthly shortfall.
Savings runway
Accessible savings ÷ Monthly gap
This estimates how many months your accessible savings could cover the shortfall. If there is no monthly gap, a savings runway is not required for that scenario.
How the result is interpreted
The test uses these figures to place the scenario into one of three simple categories: Resilient, Tight or Shortfall. These are stress-test indicators, not assessments of your household’s overall financial health.
Important assumptions
The calculation is a snapshot based only on the numbers you enter. It assumes those figures remain unchanged for the scenario and does not account for factors such as future income changes, inflation, investment returns, insurance payouts, government support or changes in household spending.
