How this calculator works
Your essential monthly costs are added up and multiplied by the number of months you want covered. What you've already saved comes off the target, and the remainder divided by your monthly savings gives the time to finish.
Worked example

How much should an emergency fund be?
The usual guideline is three to six months of essential expenses. Essential means what you'd still have to pay if your income stopped: housing, utilities, groceries, insurance, transportation, minimum debt payments and childcare. It doesn't include dining out, travel or extra savings.
Lean toward six months or more if your income is variable, you're self-employed, you're the only earner in your household, or you work in an industry where job searches take a long time. Three months can be enough with two stable incomes and good insurance.
Where to keep it
An emergency fund needs to be safe and available within a day or two, not invested for growth. A high-yield savings account is the usual home: FDIC-insured, earns a competitive rate and allows withdrawals at any time. Keep it at a separate bank from your checking account if that helps you avoid dipping into it.
Once the fund is large, some people keep one month in savings and the rest in short-term Treasury bills or a no-penalty CD for a bit more yield. Avoid stocks for this money; a market drop often arrives at the same time as a layoff.
How to build it faster
The calculator shows how many months it takes at your current savings rate, so you can see what an extra $100 a month does to the timeline.
- Automate a fixed transfer on payday, even a small one.
- Direct windfalls, such as tax refunds, bonuses and cash gifts, straight to the fund.
- Start with a $1,000 starter fund, then pay down high-interest debt, then finish the full fund.
- Review subscriptions and recurring bills once and redirect what you cut.
What counts as an emergency
Use the fund for unexpected, necessary costs: job loss, medical bills, urgent car or home repairs, or emergency travel. Planned expenses such as holidays, annual insurance premiums or a new phone belong in separate savings goals; the savings goal calculator can plan those. After you use the fund, rebuild it before going back to other goals.
Frequently asked questions
How much should I have in my emergency fund?
Three to six months of essential expenses. If your essentials cost $3,500 a month, that's $10,500 to $21,000. Aim for the higher end if your income is irregular or you're the only earner.
Should I pay off debt or build an emergency fund first?
Most planners suggest a starter fund of about $1,000 first, then paying off high-interest debt such as credit cards, then building the full three to six months. Without a small cushion, any surprise expense goes back on a card.
Where should I keep my emergency fund?
In a high-yield savings account or money market account at an FDIC- or NCUA-insured institution. It should be easy to reach within a day or two and not exposed to stock market losses.
Is 6 months of expenses enough for an emergency fund?
For most households, yes. Self-employed people, single-income households and anyone in a field with long job searches may want 9 to 12 months.
Should my emergency fund be invested?
Not in stocks. The fund has to be there at full value when you need it, often during a downturn. Insured savings, money market accounts, short-term Treasury bills and no-penalty CDs are appropriate.
