How much is enough?
An emergency fund covers essential expenses if you lose income or face a large unexpected bill. The usual guideline is 3 to 6 months of essential expenses, not total spending.
- 3 months: stable job, dual income, good insurance.
- 6 months: single income or dependents.
- 9–12 months: self-employed, commission or seasonal income, or a specialized job that takes longer to replace.
Where to keep it
Keep it liquid and safe: an FDIC- or NCUA-insured high-yield savings or money market account. Not in stocks, and not tied up in a CD with large penalties.
Building it
Start with a smaller goal, such as $1,000 or one month, then keep going. Automate a monthly transfer and add windfalls.

What your results mean
The target is enough to cover essential bills for the months you chose. Months covered today shows how long your current savings would last.
Tips
- Count only essentials, not dining out or travel.
- Keep the fund in a separate high-yield savings account.
- Refill it promptly after you use it.
