Free expat emergency fund calculator
The result updates instantly as you type. The target is your monthly expenses multiplied by the months you want covered. Share the link above and anyone opening it sees your exact inputs.
Illustrative figures notice: the default inputs (€1,800 of monthly expenses, 3 months, €1,200 saved, €300 a month) are an example showing the calculator’s method — they are not a recommendation for your situation. Enter your own real expenses for a plan that fits you. Methodology: target = monthly expenses × months to cover; gap = target − already saved (never below zero); months to reach = gap ÷ monthly saving, rounded up.
Worked example: €1,800 a month, 3 months, €1,200 saved
Example: target €5,400 — €4,200 to go, reached in 14 months
Monthly expenses of €1,800 times 3 months gives a target of €5,400. With €1,200 already saved, the gap is €4,200. Saving €300 a month closes it in 14 months (€4,200 ÷ €300 = 14). Try it live in the calculator above: it is pre-filled with exactly this example. Raise the cover to 6 months and the target doubles to €10,800 — the gap becomes €9,600 and the same €300 a month takes 32 months, which is why most expats build the fund in stages.

What is an emergency fund?
An emergency fund is cash you can reach immediately when something goes wrong — a lost job, a medical bill, a broken laptop, an urgent flight home. It is not an investment and it is not savings for a holiday: its job is to stop one bad month from becoming debt. For expats the stakes are higher than at home, because a lost job abroad can also mean a lost visa, a lost home and a flight home in the same month, and because family support is usually a flight away rather than a drive away.
Why three months is the floor, not the goal
Three months of expenses covers the most common emergencies: a short gap between jobs, one large bill, or a sudden move. But it does not cover a long job search in a foreign labour market, where hiring cycles are slower and visa rules can limit your options. That is why the standard guidance used by consumer finance authorities across the EU is three to six months — three to start, six to be safe, and more if you freelance or support family back home. The calculator lets you test 3, 6, 9 or 12 months and see the real cost of each choice.

How to use it in 4 steps
- Enter your real monthly expenses — rent, bills, food, transport, insurance and the money you send home. Use a three-month average, not your cheapest month.
- Choose how many months to cover: 3 to start, 6 for safety, 9–12 if you freelance or are the only earner.
- Enter what you have already saved in a separate, accessible account — not money mixed with your spending balance.
- Set a monthly saving you can keep in a bad month, not a good one, and read the months-to-target figure. If it is longer than two years, raise the monthly saving or start with the 3-month target and extend later.

The formula, with every variable explained
Target = monthly expenses × months to cover. Gap = target − already saved. Months to reach = gap ÷ monthly saving.
Monthly expenses is everything you must pay in a normal month, averaged over three months. Months to cover is how long the fund must last — 3, 6, 9 or 12. Already saved is cash in a separate accessible account, counted only if you can reach it within a day. Monthly saving is the amount you move into the fund each month. Gap is what is still missing; if you have already saved more than the target, the gap is zero and the fund is complete. Months to reach is the gap divided by the monthly saving, rounded up to whole months.
