Quick answer: An emergency fund calculator works out how much cash you should set aside by multiplying your essential monthly expenses by a target of 3 to 6 months. For example, if your essentials are $3,000 a month, a 6-month emergency fund target is $18,000.

Frequently Asked Questions

How much should I have in an emergency fund?

A common target is 3-6 months of essential expenses. People with variable income, dependents or less job security should lean toward 6 months or more.

How does the calculator work out my target?

It multiplies your essential monthly costs (housing, food, utilities, transport, insurance, minimum debt payments) by the number of months you choose to cover.

Where should I keep my emergency fund?

In a separate, easy-access account such as a high-yield savings account — somewhere safe and liquid, not invested in stocks where the value could drop just when you need it.

Should I build an emergency fund before paying off debt?

Most experts suggest a small starter fund (around one month of expenses) first, then aggressively repaying high-interest debt, then growing the fund to the full 3-6 months.
