Emergency fund calculator: how much do you actually need?
Three to six months of essential expenses, not lifestyle spending. The example household spends $2,700 a month on essentials, so a 6-month fund is $16,200. With $2,000 saved and $400 a month going in, the gap closes in 36 months. Build yours from your real categories below.

Build your fund
Essentials, not lifestyle
The fund covers the months you cannot work, not the months you want to enjoy. Housing, groceries, transport to the job you are trying to keep, insurance, and debt minimums: the $2,700 above. Dining out, subscriptions, and the vacation line are not in it, which is why the fund is smaller than your total spending and why it is honest. If the number feels unreachable, that is the point of the next section.
The starter milestone: $500–$1,000 first
A full 6-month fund is a 3-year project at $400 a month, and projects that long die. So the plan has a first milestone: $500–$1,000, the size of the surprise car repair or the emergency vet bill that would otherwise go on a 21% card. Hit the starter fund in 2–3 months, then the full fund becomes maintenance rather than a mountain. The fund is also meant to be tapped and replenished: spending it on the emergency it exists for is success, and the contribution resumes the next month.
Where to keep it
A high-yield savings account, separate from checking: earning ~4% while staying liquid and FDIC-insured. Not stocks (a job loss and a market crash arrive together), not the checking account it will leak out of, and not a CD you cannot touch without penalty. Separate account, boring yield, instant access: that is the whole specification.
Estimates, not financial advice. Coverage guidance is general; your situation sets the right number. Talk to a professional about your finances.
Common questions
How much should I have in an emergency fund?
3–6 months of essential expenses: 3 for stable dual-income households, 6 for single or variable incomes, 9–12 for the self-employed. On $2,700 of essentials, 6 months is $16,200.
What counts as an essential expense?
Housing, groceries, transport, insurance, and debt minimums. Not dining out, subscriptions, or vacations.
Where should I keep my emergency fund?
A high-yield savings account, separate from checking: liquid, FDIC-insured, earning interest. Not stocks and not a CD with penalties.
Should I save $1,000 first?
Yes. A $500–$1,000 starter fund covers the surprise repair that would otherwise go on a credit card, and it is reachable in 2–3 months.
Is it okay to spend my emergency fund?
That is what it is for. Spend it on the emergency, then resume contributions to replenish it.
Emergency fund or pay off debt first?
Both, in order: a $1,000 starter fund first, then high-interest debt, then the full fund. See our save-vs-debt page for the math.
How long does it take to build a 6-month fund?
At $400 a month against a $14,200 gap: 36 months. The starter $1,000 milestone takes under 3 months, which is the part that protects you soonest.
