How it works
- Enter your essential monthly expenses.
- Choose your target number of months of coverage.
- Add your current savings and monthly contribution to see how much more you need, and when you'll reach it.
The formula
Your target fund is monthly expenses multiplied by your chosen coverage period:
Target fund = Monthly expenses × Months of coverage
FAQ
How many months of expenses should I save?
3-6 months is the most common guideline, with people in less stable income situations (freelance, commission-based) often aiming for 6-12 months. Choose what feels right for your situation.
Should this include all my expenses or just essentials?
Essentials only — rent/mortgage, utilities, groceries, insurance, minimum debt payments. Discretionary spending (dining out, subscriptions) usually gets cut first in an actual emergency.
Where should an emergency fund be kept?
Somewhere accessible without penalty, like a high-yield savings account — not invested in the stock market, since you need it available exactly when markets might also be down.
Is my financial data uploaded anywhere?
No — every calculation happens locally in your browser.
