Emergency Fund Calculator
"Three to six months" is a slogan, not an answer. This tool turns your real situation, expenses, dependents, debt, and how stable your income is, into a target amount and a number of months that fit you, not a generic rule. Download the result as a PDF when you are done.

Reading your target
The big number is the buffer we suggest you hold in accessible cash before an open-ended quit makes sense, your essential monthly spend multiplied by a month count that rises with the risks in your situation. It is a floor, not a ceiling: more is always safer, and the number assumes you have priced your expenses honestly. If that figure is a guess, the budget planner will fix it first.
What moves the number
- Dependents raise it. Each person relying on your income adds fixed costs that cannot flex in a tight month, so the buffer has to be deeper.
- Debt raises it. Minimum payments do not pause when income stops. A fund that ignores them runs out faster than it looks.
- Unstable income raises it most. Commission, contract, seasonal, or self-employed earning means longer and less predictable gaps, the single biggest factor here.
- Being the only earner raises it. A second income in the household is its own emergency fund. Without one, yours carries the whole load.
A worked example
Priya spends 3,200 a month, has one dependent, pays 900 in debt minimums, freelances (so income is self-employed), and is the sole earner. The tool starts at three months, adds for the dependent, the debt, the self-employed income, and the single-earner status, landing near 9 months, or roughly 28,800.
For a salaried worker with no dependents, no debt, and a partner who also earns, the same expenses produce a three-month target of 9,600. Same spending, very different buffer, which is exactly why the slogan fails and the situation matters.
Methodology, in plain English
Target months equals 3 (base) plus dependents times 0.75 (capped) plus 1 if you carry monthly debt plus 2 for variable income or 3 for self-employed plus 1 if you are the only earner, bounded between 3 and 12 months. Target amount equals rounded months times monthly essential expenses. The model is a considered rule of thumb, not a regulation; it cannot see your contract, your country's safety net, or a known one-off cost. Full assumptions on the methodology page. Educational estimates, not financial advice.
Build the fund without stalling forever
Separate the accounts
Keep the emergency fund somewhere you will not casually spend it, a different bank, an account without a card. Friction protects the buffer.
Do not confuse it with runway
If you plan to quit, you need this buffer and separate runway to live on. Spending the buffer as runway leaves you exposed. Size your runway
Set a date, not just a number
Turn the gap into a timeline with the savings goal calculator so the target stops being someday.
Liquid and boring
Accessible cash that earns a little interest, not investments that can drop the week you need them. Availability beats yield here.

Frequently asked questions
How many months of expenses should an emergency fund cover?
Three to six months of essential expenses is the standard range for someone with stable employment. The number rises with dependents, debt obligations, variable or self-employed income, and being the only earner in a household. For an open-ended quit specifically, the upper half of that range or beyond is the safer default.
Is an emergency fund the same as quitting runway?
No, and conflating them is a common mistake. An emergency fund is money set aside for genuine emergencies, a medical bill, a car failure, a sudden job loss. Quitting runway is money you plan to spend on living costs during a deliberate gap. If you spend your emergency fund as runway, you have no buffer left for an actual emergency.
Should I count investments toward my emergency fund?
Generally no. An emergency fund should be liquid and stable, cash or near-cash you can access within days without selling at a loss or paying penalties. Investments can fall exactly when you need them, and retirement accounts often carry early-withdrawal costs. Keep the buffer in accessible savings.
Where should I keep an emergency fund?
In a separate, easily accessible account that earns some interest but carries no withdrawal penalty or market risk, a high-yield savings account in the US, an easy-access savings account in the UK, or the equivalent in your country. The goal is availability and stability, not return.
People also ask
How much emergency fund do I need if I am self-employed?
More than an employee with steady pay. Self-employed and freelance income is lumpy and gaps between clients are unpredictable, so a buffer nearer nine to twelve months of essential expenses is a safer target. This calculator adds extra months automatically when you select self-employed income.
Should my emergency fund cover my whole salary or just expenses?
Just your essential expenses, not your gross salary. The point of the fund is to keep the lights on and obligations paid if income stops, so it is sized on what you must spend each month, not what you earn. Discretionary spending can flex in a genuine emergency.
How long does it take to build an emergency fund?
It depends on the target and how much you can set aside each month. Divide the gap between what you have and your target by your monthly saving to get the number of months. The savings goal calculator does this for you and turns it into a date.
Is the emergency fund calculator free and private?
Yes. It is free with no signup, runs entirely in your browser, and stores nothing you enter. The optional PDF summary is generated locally on your device.
