Emergency Fund Calculator
Work out how large your emergency fund should be, how many months you are already covered, and how long to finish funding it.
How it works
Target = monthly essential expenses × months of coverage · Shortfall = target − current savings · Months to fund = shortfall ÷ monthly contribution
An emergency fund is cash set aside to cover essential expenses if income stops or a large unexpected bill lands, so you avoid high-interest debt. The common guideline is three to six months of essential spending — closer to six (or more) if your income is variable, you are self-employed, or you support dependents. Keep it in a liquid, safe account like a high-yield savings account, not invested in stocks.
Worked example
With $3,500 of essential monthly expenses, a 6-month fund is 3,500 × 6 = $21,000. Starting from $4,000 you cover about 1.1 months and have a $17,000 gap; saving $400 a month closes it in roughly 3 years 7 months.
Frequently asked questions
How many months should I save?
Three months is a common minimum for stable dual-income households; six months suits most people; nine to twelve months is prudent if your income is irregular, you are a single earner, or you work in a volatile field. Match the size to how quickly you could replace lost income.
What counts as an essential expense?
Only the spending you truly could not cut in a crisis: housing, utilities, groceries, insurance, transportation, and minimum debt payments. Leave out discretionary items like dining out, subscriptions and vacations, since those pause during an emergency.
Where should I keep my emergency fund?
In a safe, liquid account you can tap within a day or two — typically a high-yield savings account. Avoid tying it up in stocks or long-term CDs; the point is guaranteed access when you need it, not maximizing return.
