How to use the emergency fund calculator
- Enter your essential monthly expenses — only what you'd still pay if your income stopped tomorrow.
- Choose how many months to cover: 3, 6, 9 or 12.
- Enter what you've already saved and what you can save each month.
- Add your savings account's APY if it earns interest.
You'll see your emergency fund target, how much is still to save, how many months your savings cover today, and the month you'll be fully funded — with a month-by-month plan you can print or download.
How much emergency fund do you need?
Your target is simple: essential monthly expenses × months of cover.
| Essentials a month | 3 months | 6 months |
|---|---|---|
| $2,000 | $6,000 | $12,000 |
| $3,000 | $9,000 | $18,000 |
| $4,000 | $12,000 | $24,000 |
| $5,000 | $15,000 | $30,000 |
3 months or 6 months?
- 3 months — stable job, two incomes, few dependents, good job prospects in your field.
- 6 months — the only earner, children or other dependents, a single income, or a job that could take a while to replace.
- 9–12 months — self-employed, freelance, commission or seasonal income, or a health condition that could affect work.
How long will it take to save?
Starting from zero with a savings account paying 4% APY:
| Saving each month | $10,000 fund | $20,000 fund |
|---|---|---|
| $250 | 3 years 2 months | 6 years |
| $500 | 1 year 8 months | 3 years 2 months |
| $750 | 1 year 2 months | 2 years 2 months |
| $1,000 | 10 months | 1 year 8 months |
Long timelines are normal — that's why many people start with a $1,000 starter fund first. It covers the most common surprises, like a car repair or a vet bill, and you build up from there.
What counts as an essential expense?
Include:
- Rent or mortgage, property tax and HOA
- Utilities and phone — electricity, water, gas, internet, cell phone
- Groceries (not dining out)
- Transportation — car payment, gas, insurance, transit
- Insurance and health — health premiums, prescriptions, regular care
- Minimum debt payments — the minimums only, not extra payments
Leave out: dining out, streaming and other subscriptions you'd cancel, travel, shopping, and savings contributions. Not sure what you spend? The 50/30/20 budget calculator splits your income into needs, wants and savings — the "needs" line is a good starting point.
Where to keep your emergency fund
An emergency fund needs to be safe and quick to reach — not invested for growth.
- A high-yield savings account at an FDIC-insured bank or NCUA-insured credit union is the usual choice. Compare rates by APY.
- Keep it separate from checking, so it doesn't quietly get spent.
- Avoid stocks and crypto for this money — they can drop just when you need it.
What counts as an emergency?
An emergency is unexpected, necessary and urgent: losing your job, a medical bill, an urgent car or home repair, emergency travel. Known costs that come round every year — car registration, holiday gifts, annual insurance — belong in a sinking fund instead, so they don't drain your emergency savings.
When you do use the fund, pause other goals and refill it first.
