An emergency fund is money set aside for the unexpected — a car repair, a medical bill, a temporary loss of income — without reaching for credit. How many months of expenses it should cover depends on how stable your income is and how many people depend on it. The calculator below shows your target amount and, if you enter what you've already saved and what you can set aside monthly, how long it'll take to get there.
Rent, food, utilities, transport, loan payments — not dining out or optional shopping.

To get this right, you need your real monthly expenses, not an estimate — if you're not sure what you actually spend, track it for a month with Monavo, then come back. Not financial advice.
The standard recommendation ranges from 3 to 12 months of essential expenses, depending on how secure your income is. With stable income and no dependents, 3 months is a reasonable floor. With dependents or less predictable income (freelancing, commission-based work), 6-9 months gives a more realistic margin. If you're the sole household earner and that income is variable, 12 months is the cautious recommendation.
The most common mistake in emergency fund math is using a rough guess for monthly expenses — usually an underestimate. A fund sized against the wrong number leaves you short exactly when you need it. That's why this calculator works best with a real, tracked figure, not a guessed one.
Just essentials — rent/mortgage, utilities, groceries, transport, required insurance. Discretionary spending (dining out, subscriptions) is the first thing cut in an emergency, so it shouldn't be part of the target.
Somewhere quickly accessible, not locked away long-term — a high-yield savings account or an instant-access deposit. Not the stock market or volatile investments, since you might need it exactly when the market is down.
Not necessarily entirely, but most experts recommend prioritizing it — without this fund, any unexpected emergency risks pushing you toward high-interest debt, which cancels out other savings progress.
Base the target on your typical lowest month, not an average — and lean toward the 9-12 month range rather than 3, for a real safety margin.
The simplest way is to track a full month, separated from discretionary spending. An expense tracker does this automatically — you see clearly what falls under "essential" without guessing.
