How to use the emergency fund calculator

  1. Add up your essential monthly expenses: housing, utilities, food, insurance, transportation and minimum debt payments.
  2. Choose how many months of expenses you want covered.
  3. Enter what you've already saved to see your progress.

How it's calculated

Target = Essential monthly expenses × Months of coverage

Use essential costs only (what you'd still need to pay if your income stopped), not your full current spending.

Example

If your essential costs are $3,200 a month, a 6-month emergency fund is $19,200. With $8,000 saved you're about 42% of the way there.

Tips

  • Start with a mini-goal of $1,000 or one month of expenses, then build up.
  • Keep the fund in a separate, FDIC-insured high-yield savings account so it earns interest but stays accessible.
  • Aim for more months if your income is irregular or you're the only earner.
  • Refill the fund right after you use it.

Frequently asked questions

How much should I have in my emergency fund?
A common guideline is three to six months of essential expenses. Consider more if you're self-employed, work in a volatile industry, have dependents, or are a single-income household.
Where should I keep my emergency fund?
Somewhere safe and easy to reach, like a high-yield savings account or money market account at an FDIC-insured bank. Avoid investing it in stocks, since you may need it when markets are down.
Should I pay off debt or build an emergency fund first?
Many people build a small starter fund first so an unexpected bill doesn't go on a credit card, then focus on high-interest debt, then finish the full fund.
What counts as an emergency?
Unexpected, necessary expenses: job loss, medical bills, urgent car or home repairs. Planned costs like vacations or holiday gifts should have their own savings goal.
