Emergency Fund Calculator
“Three to six months of expenses” is easy advice and a vague target. This calculator turns it into two concrete numbers: what you still need, and the month you will have it at your current savings rate.
Three months is the usual floor for a stable salary and a second income in the household. Six or more fits freelancers, single-income households, and anyone whose job would take a long time to replace.

A fund only grows if the money survives the month. Project your running balance first — if it dips before payday, the amount you can really set aside is smaller than it looks.
Project your balance →Size it on essentials, not on spending
The most common mistake is multiplying total monthly spending by six. That produces a target so large it feels pointless to start — and it is wrong, because an emergency month is not a normal month. Strip the figure back to what genuinely must be paid: housing, utilities, food, insurance, transport, minimum debt payments. The result is usually a third smaller and far more achievable.
Months of cover is the number that matters
A fund of 6,000 means nothing on its own. Six thousand against essentials of 1,500 is four months of breathing room; against essentials of 3,000 it is two. Watching the months-of-cover figure rise is also a better motivator than the balance, because it goes up both when you save more and when your fixed costs come down.
Why the fund and the budget are the same problem
People rarely fail to build a fund because they lack discipline. They fail because the money they planned to save was quietly needed in a month with an annual bill in it. Before committing to a monthly amount, check that it actually survives the year with the cumulative budget calculator — the months where the running balance dips are the months your savings plan will break.
Frequently asked questions
How big should an emergency fund be?
Three to six months of essential costs is the usual range. Three is reasonable for a stable salary in a two-income household; six or more suits freelancers, single-income households, and anyone in a role that takes months to replace. Size it on essentials, not total spending — in a real emergency the restaurants stop.
What counts as an essential cost?
Rent or mortgage, utilities, basic groceries, insurance, transport to work, minimum debt payments, childcare and medication. If skipping it for one month causes a real problem, it belongs in the figure.
Should I pay off debt or build the fund first?
A common order is a small starter buffer of about one month of essentials, then clearing high-interest debt, then finishing the full fund. Without any buffer the next unexpected bill goes straight back onto the card you were trying to clear.
Where should the money sit?
Somewhere boring and instantly accessible — a separate savings account you can reach the same day. Investments can fall exactly when you need the money, and a notice period turns an emergency fund into a fund for emergencies you can schedule.
What if I cannot save anything right now?
Start with the smallest amount that is still real and automatic on payday. The habit and the account matter more than the number early on, and a projection of your running balance will usually show a month or two where there is more room than it feels like.
