Emergency Fund Calculator
How big should your emergency fund be, and how close are you? Set a coverage target and see the gap and the time to reach it.
About 38 months away at $500/mo.
| Monthly essential expenses | $4,000 |
| Months of coverage | 6 months |
| Target fund | $24,000 |
| Current savings | $5,000 |
| Remaining gap | $19,000 |
| Time to reach goal | 38 months |
Base the target on essential expenses (housing, food, utilities, insurance, minimum debt payments), not your full budget. Three months is a common minimum; six or more suits variable income or single-earner households. Keep the fund somewhere safe and accessible, like a high-yield savings account.

How this calculator works
Who this is for
Anyone building — or sizing — a financial safety net. An emergency fund keeps a surprise expense or a gap in income from turning into high-interest debt, which is why it's the foundation of most financial plans.
How much should you keep?
The common guidance is three to six months of essential expenses. Lean toward three if you have very stable income and few dependents, and toward six or more if your income is variable, you're self-employed, or you're a single earner supporting a family.
Base the number on essential expenses — the bills you couldn't skip — not your entire lifestyle budget, so the target stays realistic.
Where to keep it
An emergency fund's job is safety and access, not growth. Keep it somewhere liquid and low-risk, like a high-yield savings account, so it's there instantly when you need it and isn't exposed to market swings.
Caveats
This is a straightforward target-and-timeline estimate. It doesn't account for interest earned on your savings along the way (a small boost) or for changing expenses. Revisit the target when your costs or situation change.
