Should I include discretionary spending in the expense figure?

No — use only essentials (housing, utilities, groceries, insurance, minimum debt payments). Including discretionary spending inflates the target beyond what you'd actually need to weather a real emergency.

Where should I keep this money?

Somewhere safe and immediately accessible without a penalty — a high-yield savings account is the common choice. Emergency funds are for availability, not investment growth.

I have irregular income — how does that change the target?

Lean toward the higher end (6-9 months) since a gap between paychecks is a real risk an emergency fund needs to absorb, not just a one-off unexpected bill.

About the Emergency Fund Calculator

Calculates your emergency fund target based on your essential monthly expenses and how many months of coverage you want — and how much more you need to save to reach it.

How to use it

Enter your essential monthly expenses — housing, utilities, groceries, insurance, and minimum debt payments.
Enter what you've already saved for emergencies.
Choose a target coverage of 3, 6, or 9 months.
Read your target amount and how much more you need in the result panel.

Formula

Target = essential monthly expenses × number of months of coverage

The CFPB deliberately doesn't prescribe one fixed number of months — its own guidance frames the right target as depending on your situation and the kinds of unexpected expenses you're most likely to face. The 3-6-9 month range offered here reflects the commonly cited industry rule of thumb, not an official CFPB figure.

Worked example

On $3,000/month in essential expenses, a 6-month target is $18,000 — a 3-month target is $9,000, and a 9-month target is $27,000, depending on how much of a cushion fits your situation.

Recommendations

• Base the expense figure on true essentials only (rent, utilities, groceries, insurance, minimum debt payments) — not your full monthly spending including discretionary items.
• If your income is variable or you're the sole earner in your household, lean toward the higher end of the range; a stable dual-income household with predictable expenses can often manage with less.
• Keep this money somewhere accessible without penalty (a high-yield savings account, not invested in the market) — the point is availability, not growth.

Frequently asked questions

Not as a fixed rule — the CFPB's own guidance says the right amount depends on your specific situation and likely unexpected expenses, rather than prescribing one number. 3-6 months (up to 9 for less stable income) is the widely cited industry convention, not an official CFPB figure.
