How this expat budget planner works
Choose the currency you are paid in and the currency you will spend, then type the exchange rate you see today. We never pull live rates, so the result is fully under your control — and you can test a weaker or stronger rate in seconds.
Enter your monthly gross income in your home currency and the share you expect to lose to income tax and social contributions.
Add your expected monthly costs in the destination currency: rent and utilities, groceries, transport, healthcare and everything else.
The planner converts your net income, subtracts your costs and shows what is left each month in both currencies, your savings rate and a projection of savings over the time you plan to stay.
The budget math
Everything converts through the single rate you enter:
Monthly surplus (destination) = gross × (1 − tax %) × rate − living costs
- rate = destination units per 1 home unit
- Home-currency amount = destination amount ÷ rate
- Savings rate = surplus ÷ net income
- Projection = monthly surplus saved each month, grown at your optional return
Worked example
Sam is moving from the US to Lisbon, earning $6,500 a month before tax from a remote US employer and estimating 25% for taxes. Using an exchange rate of 1 USD = 0.92 EUR, net income of $4,875 becomes €4,485.
Monthly costs are €1,400 for rent and utilities, €450 groceries, €90 transport, €160 health insurance and €600 for everything else — €2,700 in total, or about $2,935.
That leaves €1,785 (about $1,940) every month, a 39.8% savings rate. Kept in cash for five years, that adds up to €107,100 — roughly $116,413 at the same rate.
If the dollar weakened to 0.85 EUR, Sam's surplus would fall to about €1,444 — a reminder to plan with a cushion.
Budget in the currency you spend
The biggest budgeting trap for expats is thinking in the wrong currency. Your rent, groceries and transit pass are priced locally, while your salary or savings may still be in dollars or pounds. A budget that only looks at one side hides the risk that sits between them: the exchange rate.
This planner keeps both views side by side. Costs are entered in the destination currency because that is how you'll pay them; income is entered in the currency you are paid in. The exchange rate connects the two.
Why you type the exchange rate yourself
Exchange rates move every day, and the rate you actually get from your bank or transfer service is usually a little worse than the mid-market rate shown in search results. Typing your own rate means the budget reflects what you'll really receive.
Use it as a stress test. Try a rate 10% worse than today's: if your budget still works, you have a healthy margin. If it tips into a deficit, consider a larger emergency fund, a local-currency income source or a cheaper housing option.
Estimating taxes as an expat
Taxes abroad depend on your residency, where your work is performed, the type of income and any tax treaty between the two countries. Many countries tax residents on worldwide income, and some offer special regimes for newcomers.
US citizens remain subject to US tax wherever they live and must still file every year, although the Foreign Earned Income Exclusion and Foreign Tax Credit often prevent double taxation. Read our guide to US taxes for Americans abroad, and get professional advice before you rely on a single percentage.
Costs newcomers underestimate
Housing deposits of two or three months, agency fees, furnishing an unfurnished apartment and residency or visa fees can add up to several months of rent in your first year. Budget them separately from your monthly costs.
Healthcare is another surprise. Some countries require private insurance for residence permits, and international plans can cost far more than local ones. Flights home, international transfer fees and keeping a US phone number or storage unit also belong in the 'everything else' line.
Building savings while living abroad
Decide early which currency your emergency fund lives in. Holding three to six months of expenses in the destination currency protects your day-to-day life from exchange-rate swings, while long-term savings can stay in the currency of your eventual retirement.
The savings projection uses your monthly surplus and an optional return. Keep the return at 0% for cash, and treat any projection as a direction, not a promise — exchange rates, taxes and costs will all change over a multi-year stay.
Use the budget before you sign a lease
Run the numbers for two or three neighborhoods or cities before committing. Small differences in rent or transport compound over a year, and seeing them in both currencies makes trade-offs concrete.
Our moving-abroad money checklist covers banking, transfers and paperwork step by step, and the 50/30/20 budget guide is a useful sanity check once you know your net income.
