Emergency fund calculator
The point of an emergency fund is not a round number. It is the number of months you could go without income.
Essentials, not your whole budget
The most common mistake is sizing an emergency fund against normal spending. An emergency fund covers the months when income stops, and in those months you are not paying for holidays, restaurants or subscriptions. What you must keep paying is housing, utilities, food, transport to interviews, insurance and minimum debt payments.
Sizing against essentials rather than total spending typically cuts the target by 20-35%, which turns an intimidating goal into a reachable one. It also produces a more honest answer, because it is the figure you would actually need.
How many months
Three to six months is the standard advice, but the right figure depends almost entirely on how quickly your income could be replaced:
- Three months — two stable incomes in the household, in-demand skills, no dependants.
- Six months — the sensible default for most single-income or single-earner-dominant households.
- Nine to twelve months — self-employed, commission-heavy, seasonal, or working in a niche where a comparable role takes a long time to find. Also worth it if a health condition makes a gap in cover expensive.
Job searches in senior or specialised roles routinely run past six months. If your last search took a long time, size for that rather than for the advice.
Where to keep it
The fund needs to be reachable within a day or two and must not be able to fall in value. That means an instant-access savings account or a money market account — not stocks, not a fixed-term deposit that penalises early withdrawal, and not the current account it will get spent from by accident.
Keeping it in a separate, deliberately inconvenient account is a genuine behavioural advantage. Interest matters less than people think at these sizes: the difference between a poor and a good rate on $12,000 is a few hundred a year, while spending the fund by mistake costs all of it.
Building it without stalling everything else
If you have high-interest debt, the usual sequence is to build a small starter buffer of about one month first, then attack the debt, then finish the fund. Carrying credit card debt at 22% while holding six months of cash is expensive; having no buffer at all guarantees the next unexpected bill goes back on the card.
If your employer matches pension contributions, take the match before finishing the emergency fund. A 50% or 100% match is a return no savings account will ever approach, and it is usually irrecoverable if skipped.
Common questions
Should the fund cover all my spending or just essentials?
Essentials only — housing, utilities, food, transport, insurance and minimum debt payments. In a genuine emergency, discretionary spending stops, and sizing against your full budget inflates the target by a third or more for no benefit.
Three months or six?
It depends on how fast your income could be replaced. Three is reasonable for a two-income household with in-demand skills; six suits most single-income households; nine to twelve suits the self-employed and anyone in a specialised field where searches run long.
Should I pay off debt or build the fund first?
Usually a small starter buffer of about one month, then high-interest debt, then the full fund. Holding six months of cash while paying 22% on a credit card costs you money, but having no buffer means the next surprise goes straight back on the card.
Where should I keep an emergency fund?
Somewhere accessible within a day or two that cannot fall in value — an instant-access savings or money market account. Not invested, not locked in a fixed term, and ideally not in the account you spend from day to day.
