Emergency Fund Calculator

Updated · By the CalculatorDash editorial team · How we check our maths

Quick answer

A common target is 3 to 6 months of essential expenses; 6 to 12 if your income is irregular or you are the only earner. With $3,500 of essential costs a month and a 6-month target, you need $21,000. Saving $500 a month from $4,000 already saved gets you there in about 34 months.

How this calculator works

An emergency fund is cash set aside for a job loss, a medical bill or a broken-down car, so a bad month doesn't become credit card debt. It should cover essentials only: housing, utilities, insurance, food, transport and minimum debt payments, not holidays or eating out.

How many months you need depends on how quickly you could replace your income. Two stable salaries in in-demand jobs might need three months; a single earner with children, or a freelancer with uneven income, is safer with nine to twelve.

Keep the money somewhere boring, safe and quick to reach, such as a high-yield savings account or a money market fund. Investing it in shares defeats the purpose because markets often fall at the same time jobs are lost.

The formula

Essential expenses
housing + bills + food & transport + minimum debt payments
Target
essential expenses × months of cover
Time to reach
(target − already saved) ÷ monthly saving, rounded up

Worked example

$1,600 + $600 + $900 + $400 = $3,500 a month of essentials. Six months is $21,000. You have $4,000, so $17,000 is left; at $500 a month that takes 34 months.

Tips

  1. 01Start with a mini goal of one month's essentials; it removes most of the stress.
  2. 02Automate a transfer on payday so saving happens before spending.
  3. 03Put windfalls such as tax refunds and bonuses straight into the fund until it is full.

Frequently asked questions

How much should be in an emergency fund?

Three to six months of essential expenses for most households, and more if your income is irregular or you support others alone.

Should I pay off debt or build an emergency fund first?

Build a small buffer (about one month) first, then attack high-interest debt, then finish the full fund.

Where should I keep my emergency fund?

In a high-yield savings account or similar safe, instant-access account, separate from your everyday account.
