What is an emergency fund?
An emergency fund is money set aside specifically for unplanned expenses — a job loss, a medical bill, a car breakdown, or an urgent home repair. It sits in a separate account from your everyday spending so you don't dip into it for routine purchases. The purpose is simple: when something expensive goes wrong, you cover it with savings instead of credit cards or loans. Financial planners call it the foundation of a sound financial plan because without it, a single unexpected expense can spiral into months of high-interest debt.
How to use this calculator
- Enter your monthly essential expenses — rent, utilities, groceries, insurance, minimum debt payments, transport. Leave out discretionary spending you could cut in a crisis.
- Choose your coverage target — 3 months is a common starting point; 6 months gives more cushion for job loss or a single-income household.
- Add what you've saved so far and how much you can contribute each month. The calculator shows your target, how long it takes, and your progress bar.
Example
Your essential expenses are $3,500/month and you want 6 months of coverage — a $21,000 target. You already have $2,000 saved and can add $300/month to a high-yield account at 4% APY. You're currently about 10% funded and will reach your full target in roughly 4 years 10 months, with interest covering about $1,800 of the gap.
Frequently asked questions
How much should I have in an emergency fund?
Most financial advisors recommend 3 to 6 months of essential expenses. Three months works for dual-income households with stable jobs; six months or more is better for single-income earners, freelancers, or anyone in a volatile industry.
What counts as a monthly expense for an emergency fund?
Focus on essentials you cannot skip: rent or mortgage, utilities, groceries, insurance premiums, minimum debt payments, transportation, and prescriptions. Leave out discretionary spending like dining out or subscriptions you could cancel in a crisis.
Where should I keep my emergency fund?
A high-yield savings account is ideal — it earns interest while keeping the money liquid and FDIC-insured. Avoid investing your emergency fund in the stock market since you may need it during a market downturn.
Should I pay off debt or build an emergency fund first?
Start with a small buffer of around $1,000 to avoid going deeper into debt for unexpected expenses. Then focus on high-interest debt. Once that's gone, build the fund to 3-6 months.
How do I build an emergency fund on a tight budget?
Start with whatever you can — even $25 or $50 a month. Automate the transfer so it happens without thinking. Every raise, bonus, or tax refund is a chance to add a lump sum. Small amounts add up.
