Emergency fund calculator

What is an emergency fund?

An emergency fund is money set aside only for genuine surprises, kept somewhere you can reach quickly. The usual guideline is three to six months of essential expenses: housing, utilities, groceries, transport, insurance and minimum debt payments. Discretionary spending is left out because you would cut it in a crisis anyway.

It is a common gap. In the Federal Reserve’s survey of US households in 2024, 63% of adults said they would cover a hypothetical $400 emergency expense using only cash or its equivalent; the rest would need to borrow, sell something or could not pay it (Federal Reserve, May 2025).

How many months of expenses do I need?

Three months is a reasonable floor for a stable salary with no dependents; six suits most households with children or one income; nine to twelve makes sense for freelancers and anyone with irregular pay. The less predictable your income, and the longer it would take to replace it, the bigger the fund should be.

• 3 months: two incomes or a secure job, no dependents.
• 6 months: single-income households, people with dependents, cyclical industries.
• 9–12 months: self-employed, commission-based or seasonal income.

The calculator suggests a number of months from your situation; change it if your circumstances differ.

Where should I keep it?

Somewhere separate from your everyday account, easy to access within a day or two, and not exposed to big swings in value. That usually means an insured savings account rather than investments. Keeping it separate makes it less tempting to dip into for non-emergencies.

The US Consumer Financial Protection Bureau has a practical guide to building an emergency fund. This page does not recommend specific accounts or products.

How do I build it faster?

Start with a small first target, such as one month of essentials, then automate a fixed transfer on payday. A first milestone you can reach within a few months is motivating, and automation removes the monthly decision. Add windfalls like tax refunds directly to the fund.

1. Set a starter goal of one month of essential costs.
2. Automate a transfer on payday; the 20% bucket in the 50/30/20 rule is a natural home for it.
3. Put part of any bonus or refund straight in.
4. If you use the fund, refilling it becomes the next priority.

Frequently asked questions

How much should an emergency fund be?

Generally three to six months of essential expenses. If you are self-employed, have irregular income, dependents or a less secure job, aim for six to twelve months.

Should I save an emergency fund or pay off credit card debt first?

A common approach is to build a small buffer first (around one month of essentials), then focus on high-interest debt, then finish the full fund. The buffer stops new surprises from going back on the card.

Should my emergency fund be invested?

Its job is to be available, not to grow. Most guidance suggests keeping it in cash savings you can reach quickly. This is general information, not investment advice.

What counts as an emergency?

Something unexpected and necessary: job loss, urgent medical or dental costs, essential car or home repairs. Holidays, sales and planned purchases are better covered by separate savings goals.
