How it works
An emergency fund covers essential costs if you lose income or face an unexpected bill, so you do not have to rely on credit cards. The usual guideline is three to six months of essential expenses.
Count only what you must pay: housing, utilities, food, transportation, insurance and minimum debt payments. Discretionary spending would be cut in a real emergency.
Aim for the higher end (six months or more) if your income is irregular, you are the sole earner, or your job would take a long time to replace.
Formula
Target = monthly essential expenses × months of coverage
Questions people ask
How many months of expenses should I save?
Three months is a common minimum for dual-income households with stable jobs. Six to twelve months is safer for single earners, self-employed people, or those in volatile industries.
Where should I keep an emergency fund?
Somewhere safe and quickly accessible: a high-yield savings account or money market account. Avoid investing it in stocks, which can drop when you need the money.
Should I build an emergency fund or pay off debt first?
Many planners suggest a starter fund of $1,000–$2,000 first, then paying down high-interest debt, then building the full fund.
