What is an emergency fund?
An emergency fund is money you set aside in a regular savings account to cover unexpected expenses without going into debt. Job loss, a car repair, a medical bill, a broken appliance. The rule of thumb is 3 to 6 months of your essential living expenses.
If you spend $3,500 a month on rent, food, utilities, and transportation, your target emergency fund is $10,500 to $21,000.

- Enter how much you can save toward this goal each month
- Your target amount, progress percentage, and months-to-goal update instantly
- Use the boost slider to see how saving a bit more each month shortens your timeline
Why your timeline matters more than the number
Most people know they need an emergency fund. The reason they don’t have one is that saving $15,000 sounds impossible, but saving $400/month for 37 months doesn’t. This calculator shows you the actual timeline so the goal stops feeling abstract.
If you’re starting from zero and can save $500/month, a 3-month fund on $3,000/month in expenses takes 18 months. Bump that to $700/month and you’re done in 13 months. That difference is visible here, and that’s what actually motivates people to change their savings rate.
What counts as a monthly expense
Only include expenses that would continue if you lost your job tomorrow: rent or mortgage, utilities, groceries, minimum debt payments, health insurance, transportation.
Leave out dining out, streaming subscriptions, gym memberships, and anything discretionary. The goal is to survive, not to maintain your current lifestyle. A lean emergency fund number is easier to hit and still protects you from the scenarios that actually destroy finances.
3 months vs. 6 months: which is right for you
The classic advice is 3 to 6 months, but that range is deliberately vague.
Go with 3 months if you have a stable job in a field with quick rehire time, a partner with income, or strong family support. Go with 6 months if you’re self-employed, in a niche industry, have dependents, or live in a high cost-of-living area. The 2025 average job search for laid-off workers is about 5 months, so the “3 months is enough” advice is increasingly outdated for anyone in tech or specialized roles.
FAQ
How much should I have in my emergency fund?
The standard target is 3 to 6 months of your essential monthly expenses. If your bare-bones monthly costs (rent, food, utilities, transport, minimum debt payments) total $3,000, your emergency fund target is $9,000 to $18,000. The exact number depends on your job stability, whether you have dependents, and how quickly you could find new income if you needed to.
How long does it take to save an emergency fund?
It depends on your target amount and how much you save each month. If you need $12,000 and save $400/month, it takes 30 months. Save $600/month and you’re there in 20 months. This calculator shows you the exact timeline based on your numbers and also shows what happens to that timeline if you increase your monthly contribution.
Where should I keep my emergency fund?
A high-yield savings account (HYSA). You want it accessible within 1 to 2 business days but not so easy to spend that you raid it for non-emergencies. In 2026, many HYSAs pay 4.5% to 5% APY. Keep it at a separate bank from your checking account. The slight friction helps you leave it alone.
Should I pay off debt before building an emergency fund?
Build a starter emergency fund of $1,000 first. Then focus on high-interest debt (anything above 7%). Once high-interest debt is gone, build the full 3 to 6 months fund. Skipping the starter fund entirely means one car repair or medical bill goes straight onto a credit card, undoing months of debt payoff progress.
Is my emergency fund too big?
There’s no such thing as too much in cash savings. But beyond 6 months, the opportunity cost adds up. Money sitting in a savings account earning 4.5% could be invested in a low-cost index fund earning 8% to 10% over time. If you’re well past your 6-month target, consider investing the excess rather than letting it accumulate in cash.
What if I have irregular income?
Freelancers and contract workers should target 6 to 9 months, not 3. Your income gap in a slow month could itself be the “emergency.” Calculate your monthly savings target based on your average monthly income over the last 12 months, then set the goal at the higher end of the range.
Does my emergency fund earn interest?
Yes, if you keep it in a HYSA or money market account. This calculator uses a simple savings assumption with no interest, so your real timeline will be slightly shorter if you’re earning 4% to 5% APY. The difference on a $15,000 balance over 2 years is roughly $600 to $1,500, but that’s not the main reason to pick a savings account.
Can I use a Roth IRA as an emergency fund?
Technically you can withdraw Roth IRA contributions (not earnings) at any time without penalty. Some people use this as a hybrid strategy. The downside is that withdrawn contributions lose years of compound growth. That money is gone from the account permanently. Use a Roth IRA as a true last resort, not a primary emergency fund.
What counts as an emergency?
Job loss, medical expenses not covered by insurance, urgent car or home repairs, a family crisis requiring travel. What does not count: a sale on flights, a holiday gift, a new phone, or a planned but inconvenient expense. The test is: is this unexpected AND necessary? If yes to both, it’s an emergency.
How often should I update my emergency fund target?
Recalculate any time your monthly expenses change significantly: a new apartment, new job, new dependent, or major lifestyle change. A good habit is to revisit it once a year when you review your overall finances.
About this calculator
Most emergency fund calculators give you one number and stop there. This one shows you the journey: a live progress bar, a month-by-month countdown, and a slider that lets you see exactly how saving a bit more each month changes your timeline. No signup, no paywall, no guessing. The formula is straightforward: target amount minus current balance, divided by monthly contribution. That’s it, shown clearly.
