How to Track Your Net Worth When You Live Abroad
Living abroad is financially messy. You keep your home-country bank accounts open “just in case.” You open new ones in your new country. Maybe you have investments in a third country. Your employer pays into a local pension. You own property somewhere that uses a different currency.
Tracking net worth under these conditions is harder than it needs to be, but you can make it manageable.
Step 1: inventory everything
Before connecting apps or building spreadsheets, list every financial account you have. Expats routinely forget accounts because they’re spread across countries and apps.
Go through these categories:
- Home country: checking accounts, savings, investment accounts, retirement accounts (401(k), ISA, SIPP, Riester, etc.), property, loans
- Current country: checking accounts, savings, local pension, property, car loans
- Third countries: old employer pension plans, inheritance accounts, rental property
- Everywhere: credit cards, student loans, personal debts
Write them all down with the institution, country, currency, and approximate balance. This list is your baseline.
Step 2: pick a base currency
You need one currency for your “official” net worth. Picking the right one matters because exchange rate moves will affect your number.
Pick the currency where you spend the most. If you live in Germany and your rent, groceries, and daily life are in EUR, use EUR. If you plan to retire somewhere else, you might want to track in that country’s currency instead.
Whichever you pick, stick with it. Changing base currencies makes historical comparisons useless.
Step 3: automate what you can
Logging into six banks in three countries every month is not sustainable. Most people do it twice and then stop.
PopaDex connects to 15,000+ banks in 30+ countries. If your banks support PSD2 open banking (most European banks do), you can auto-sync balances daily. That eliminates the most tedious part of tracking.
For accounts that don’t support auto-sync:
- US 401(k) accounts: check quarterly and update manually
- Foreign property: update value annually based on local estimates
- Pensions you can’t access: update annually based on statements
The goal is to auto-sync 80% of your assets and manually update the rest quarterly.
Step 4: handle property correctly
Property is usually the largest asset for expats, and it causes the most confusion.
Include it at market value, not purchase price. Use recent comparable sales or local government valuations (WOZ in the Netherlands, catastral in Spain, etc.).
Subtract the mortgage in its original currency. If you have a €200,000 apartment with a €140,000 hipoteca, your net property value is €60,000.
Don’t convert the property value back and forth. Track the property in its local currency and let your tracker handle the conversion. PopaDex does this automatically.
Step 5: don’t forget pensions
Expats accumulate pension rights across countries. These are real assets, even if they’re decades away:
- UK workplace pension: check annual statement or log into the provider
- US 401(k) from a previous employer: log into Fidelity/Vanguard/etc.
- German Riester-Rente or betriebliche Altersvorsorge: check annual Standmitteilung
- State pensions: estimate based on years of contributions per country
You can include pensions at their current transfer value or projected value. Using current value is more conservative and simpler.

Step 6: prepare for tax season
Different countries want different snapshots:
| Country | What you need | Reference date |
|---|---|---|
| Netherlands | Total worldwide assets for Box 3 | January 1st |
| Spain | Foreign assets above €50,000 (Modelo 720) | December 31st |
| Germany | Foreign investment income | Full tax year |
| Norway | Worldwide assets for skattemelding | December 31st |
| UK | Foreign income and gains | April 5th |
| US (expats) | Worldwide income + FBAR for accounts >$10,000 | December 31st |
Having a net worth tracker that shows your total assets at a specific date eliminates the scramble every April.
Common expat mistakes
Leaving too much cash in your home country. It’s comforting to keep your “old” savings account open, but money sitting in a zero-interest account in a currency you no longer spend loses value twice, to inflation and to exchange rate drift.
Not tracking currency exposure. If 70% of your net worth is in GBP but you live and spend in EUR, a 10% drop in GBP costs you 7% of your real purchasing power. Track your currency allocation the way you’d track stock allocation.
Ignoring foreign tax obligations. Many countries require worldwide asset declarations. Not knowing what you own in total is how people accidentally under-report. A consolidated tracker is the simplest fix.
Checking too often or not often enough. Weekly checks create anxiety over exchange rate noise. Annual checks miss problems. Monthly is the right frequency for most people.
