How much do you need?
Add up your essential monthly costs — housing, utilities, groceries, insurance, transportation and minimum debt payments — and multiply:
- 3 months if your income is steady and you have a second earner.
- 6 months or more if you're self-employed, a single-income household or work in an unstable industry.
Example: essentials of $2,800 a month → a target of $8,400 to $16,800. A starter goal of $1,000 covers most small emergencies while you build up.
What counts as an emergency?
Job loss, urgent medical or dental bills, essential car or home repairs, emergency travel. Planned costs — holidays, annual insurance premiums, a new phone — belong in a sinking fund instead.
Where to keep it
Somewhere safe, separate and quick to reach: an FDIC- or NCUA-insured savings account, ideally one with a competitive APY. Keeping it apart from checking stops it slowly turning into spending money.
How to build one
- Set a monthly amount and automate it on payday — the savings goal calculator tells you how much.
- Put windfalls in: tax refunds, bonuses and cash gifts.
- Use the 20% savings bucket of a 50/30/20 budget until you reach the target.
