# How much should you have in an emergency fund?

> Three to six months of expenses is the usual answer. What counts as an emergency, how to work out your own number, and how to build the fund a step at a time.

An emergency fund is money you set aside for things you can't plan for, like
losing a job, a medical bill, or a car repair you need to get to work. The
Federal Reserve Bank of St. Louis and FINRA both suggest saving three to six
months of essential expenses. With an emergency fund, a bad month stays a bad
month. Without one, it can turn into a debt you're still paying off a year
later.

## Why it matters

Without savings, emergencies go on credit cards. A $1,200 car repair becomes a
card balance, and the interest makes that repair cost more every month it
isn't paid off.

Lots of people don't have that cushion. In the Federal Reserve's
[survey of household finances for 2025](https://www.federalreserve.gov/publications/2026-economic-well-being-of-us-households-in-2025-executive-summary.htm), 63% of adults said they'd
cover a surprise $400 expense with cash or its equivalent. That includes
paying with a credit card and paying it off in full. So more than a third would
have to borrow, sell something, or couldn't cover it at all.

More than a third would have to borrow, sell something, or couldn’t cover a surprise $400 expense at all.** A grid of 100 dots, one for each of 100 adults, from the Federal Reserve’s survey for 2025. The first 63 dots are solid green: 63% would cover a surprise $400 expense with cash or its equivalent. The rest are amber rings: more than a third would have to borrow, sell something, or couldn’t cover it at all.

An emergency fund protects everything else, too. One bad week can wipe out a
budget, a plan to pay off debt, or a savings goal. The fund keeps those plans
on track.

It also buys you time. If you lose your job with three months of expenses in
the bank, you can look for the right next job instead of grabbing the first
one.

## How much

The usual rule of thumb is **three to six months of essential expenses**. The
[Federal Reserve Bank of St. Louis](https://www.stlouisfed.org/publications/page-one-economics/2025/sep/when-unexpected-happens-be-ready-with-emergency-fund) and [FINRA](https://www.finra.org/investors/insights/how-avoid-bad-financial-luck-friday-13th) both give that
range. That's expenses, not income: what it costs to keep a roof over your
head, the lights on, food on the table, and the minimum payments made.

Where you land in that range depends on how long it would take to replace your
income. The St. Louis Fed describes the fund as what pays your bills "while
you're searching for the next job." If your work is irregular, or yours is the
only income in your home, finding new work could take longer. Aim closer to
six months.

**Start smaller.** Six months of expenses is a lot of money. Iowa's Department
of Insurance and Financial Services suggests [three steps](https://smarther.iowa.gov/emergency-savings-your-financial-safety-net/): save $500
first, then one month of expenses, then three months and beyond. The Consumer
Financial Protection Bureau's
[guide to building an emergency fund](https://www.consumerfinance.gov/start-small-save-up/start-saving/an-essential-guide-to-building-an-emergency-fund/) makes the same point: even a
small amount helps.

**Diagram: Build it a step at a time: $500, then one month of expenses, then three. Three to six months is the usual goal.** Four steps rising from left to right, like stairs. Step one is $500, marked start here. Step two is one month of expenses. Step three is three months. Step four is six months. Steps three and four are marked as the usual goal: three to six months of essential expenses. The month steps are drawn to scale: three months is three times as tall as one, and six is twice as tall as three. $500 is drawn as the smallest step.

### What counts as an emergency

Losing income, medical and dental bills, urgent car or home repairs, and
emergency travel all count. The holidays, a vacation, and a yearly insurance
bill don't. You can see those coming, so they belong in
[sinking funds](https://smpl.money/learn/sinking-funds/) instead.

## How to do it

### 1. Work out your monthly essentials

Add up rent or mortgage, utilities, groceries, insurance, transportation and
minimum debt payments for a recent month.
[Tracking your spending](https://smpl.money/learn/track-your-spending/) gives you a real number
instead of a guess.

### 2. Multiply

Three times that monthly number is your starting target. Six times is the
fuller goal.

### 3. Give it its own account

Keep the fund in a savings account, apart from the account you spend from. The
St. Louis Fed's advice is to keep it "available when you need it, but not too
easily available." It also notes that many people use a savings account at a
local bank or credit union.

### 4. Make it automatic

Set up a transfer on payday, even a small one. FINRA suggests starting with "a
regular, automatic contribution of an amount you can reliably afford," and
adding extra when you can. A tax refund or a bonus is a good time for that.

### 5. Refill it after you use it

Using it is what it's for. Afterward, go back to step 4 until it's full again.

## How to do it in Simple Balance

### Find your monthly essentials

[**Reports**](https://smpl.money/docs/reports/) has an **Income and expenses** report. Group it by
month and look at your expenses for the last three months. Or use
[**Overview**](https://smpl.money/docs/the-overview/) to see spending by category over the same
dates, and add up the essential ones.

### Give the fund its own account

On [**Accounts**](https://smpl.money/docs/accounts/), add a **Savings** account for the fund. On
its form, turn off **The budget is about the money in this account**, so your
budget doesn't treat emergency money as money to spend. If you use left to
assign, moving money into the fund lowers it, and that's right: the money has a
job now.

Under Savings, Savings at $20,200.00. Under Credit card, a card named Travel Card.](https://smpl.money/screenshots/accounts-light.webp)

### Make the payday transfer repeat

On [**Recurring**](https://smpl.money/docs/recurring-transactions/), press **New recurring
transaction** and set up a **Transfer** from checking to the fund on your
payday. Each time it's due, a row shows up in
[**Staged**](https://smpl.money/docs/staged-transactions/) for you to approve once the money has
really moved. It never posts on its own.

![The recurring page before anything is set up: a New recurring transaction button, and a note that each due date puts a row on Staged transactions for you to check.](https://smpl.money/screenshots/recurrences-light.webp)

### Watch it grow

You'll see the fund's balance on **Accounts**, and it counts toward your **Net
worth** report like any other account. When you use it, record a transfer
back to checking. Then record what you spent it on in its own category, so
your reports show what the emergency really was.
