Build a real safety net. Enter your monthly expenses, how many months of coverage you want, and what you've saved — and see your target and what's left to save.
A planning target based on essential expenses — trim to true essentials for the coverage figure. Keep an emergency fund somewhere safe and accessible, not invested at risk.
The standard guidance is 3–6 months of essential expenses, and more if your income is variable or you're self-employed. Base it on the bills you'd still have to pay if income stopped — not your whole budget.
Multiply your essential monthly expenses by the months of coverage you want (commonly 3–6). This calculator shows the target and how far your current savings already gets you.
Somewhere safe and quick to access — typically a high-yield savings account, not investments that can drop right when you need the cash.
