Emergency Fund Calculator

Work out how big your emergency fund should be, and how long it will take to get there.

Rent, utilities, food, insurance, debt minimums — needs, not wants.

How big should an emergency fund be?

The standard guidance is three to six months of essential expenses — not your full spending, but the amount you'd need to cover rent or mortgage, utilities, groceries, insurance, and minimum debt payments if your income stopped tomorrow. People with variable income (freelancers, commission-based roles) or a single household income often lean toward six months or more; dual-income households with stable jobs sometimes go as low as three.

This calculator multiplies your essential monthly expenses by your chosen coverage window to get a target, then compares it to what you've already saved to show what's left. If you add how much you can realistically set aside each month, it also estimates how long it will take to close the gap.

Where should the money actually sit?

An emergency fund needs to be accessible within a day or two and shouldn't lose value to market swings, which rules out investing it. A high-yield savings account is the usual answer — it earns some interest while staying liquid. Keeping it separate from your everyday checking account also removes the temptation to dip into it for non-emergencies.

Once this fund is fully funded, many people redirect that same monthly amount toward a different goal — see the Savings Goal Calculator for a specific target, or the Retirement Savings Calculator for the long game. If you're not sure how much you can realistically set aside each month, start with the Monthly Budget Calculator.

Frequently asked questions

Should I count rent, but not streaming subscriptions?

Yes — use essential, need-to-have expenses only: housing, utilities, groceries, insurance premiums, minimum debt payments, and transportation to work. Leave out discretionary spending like subscriptions, dining out, or entertainment, since those are the first things you'd cut in a real emergency.

Is three months enough, or should I aim for six?

Three months is a reasonable floor for a stable dual-income household with low job-loss risk. Freelancers, single-income households, or anyone in a volatile industry are usually better served by six months or more.

Should my emergency fund be invested to earn a better return?

Generally no. The purpose of this money is availability, not growth — a market downturn is exactly the kind of event that can also come with job losses, which is the worst time for your safety net to have lost value.

What should I do once my emergency fund is fully funded?

Redirect the same monthly amount toward another goal. The Savings Goal Calculator works for a specific target like a home down payment, while the Retirement Savings Calculator is built for long-term investing.
