How to use the emergency fund calculator

  1. Add up your essential monthly expenses: housing, utilities, food, insurance, transportation and required 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 account so it's easy to reach but not mixed with everyday spending.
  • 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, kept separate from your everyday spending money. 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 push them into borrowing, then work on clearing any 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.
