Frequently asked questions
How many months of cover is recommended?
A commonly used guide is 3–6 months of essential expenses, though this depends on job security, income stability and personal circumstances.
What counts as an essential expense?
Housing, utilities, groceries, insurance and minimum debt repayments — discretionary spending like entertainment is usually excluded.
Where should an emergency fund be kept?
This calculator doesn't recommend products; a separate, easily accessible savings account is commonly used to keep funds available but out of everyday spending.
