Multi-country net worth system
How to track net worth across multiple countries
If your money is split across countries, a normal net worth tracker breaks quickly. You need original currencies, one base currency, live or consistent exchange rates, manual assets, liabilities, and dated snapshots.
Coverage checklist
Include the assets domestic trackers often miss
Cross-border net worth is still assets minus liabilities. The difficult part is keeping every source value, debt, and conversion assumption explainable.
Cash and investments
Record current accounts, savings, deposits, brokerages, and cash holdings in their original currencies.
Pensions and retirement
Keep former-employer plans and foreign pensions in the inventory even when access is years away.
Property and private assets
Store the local-currency estimate, valuation date, and source. Review manual values on a consistent schedule.
Mortgages and other debts
Track each liability in its original currency rather than subtracting a stale converted balance.
The model
Track source values and converted values separately
The most common mistake is overwriting everything into one currency and losing the explanation. Keep both.
Step by step
A repeatable multi-country tracking workflow
Step 1
Inventory every country
List banks, investments, pensions, property, loans, mortgages, and credit cards by country.
Step 2
Pick a base currency
Use the currency where you live, spend most, or plan long-term decisions.
Step 3
Separate synced and manual items
Bank balances may sync. Property, pensions, and private assets often need manual updates.
Step 4
Convert consistently
Use live FX rates if possible. If using a spreadsheet, keep the exchange-rate source visible.
Step 5
Save monthly snapshots
Monthly history helps separate real progress from exchange-rate noise.
Step 6
Keep tax-year dates
Some countries need asset values on specific dates. Store those snapshots before tax season.
Tool choice
When to use a spreadsheet vs an app
Use a spreadsheet for the first inventory
A spreadsheet is excellent for finding forgotten accounts and forcing a clean starting point.
Use PopaDex when updates become the problem
Automation matters once you have enough countries, currencies, and accounts that monthly updates become inconsistent.
Keep manual checks for hard-to-sync assets
Even with an app, some property, pensions, and private assets should be reviewed manually on a schedule.
Recommended path
Start with an inventory. Keep going with a dashboard.
Use the free spreadsheet if you are still mapping your accounts. Use PopaDex when you want the habit to survive month after month.

A three-country reconciliation example
In a fictional worked example, Maya initially estimates assets across the US, UK, and Singapore at $356,000. A $40,000 employee option has no current value, a dated GBP conversion lowers the UK figure by $4,700, and a corrected restricted-account balance lowers Singapore by $22,500. Her reconciled total is $288,800, a $67,200 difference. These are invented teaching figures, not a PopaDex customer result.
| Region | Rough USD estimate | Reconciled USD value |
|---|---|---|
| US | $121,000 | $81,000 |
| UK | $75,000 | $70,300 |
| Singapore | $160,000 | $137,500 |
| Total | $356,000 | $288,800 |
Record each balance in its original currency on the same snapshot date, including the outstanding loan rather than the original amount borrowed. Convert only for the reporting total using rates from that date; keep the source amounts so you can audit later changes. If a value is estimated or inaccessible, label its source, date, and restriction.
When relocating, identify which accounts can still be accessed, whether a broker permits continued residence abroad, and whether tax or reporting rules affect the holding. Do not close an account merely to simplify a dashboard. A single view is useful precisely because it can show assets and liabilities held in different countries without pretending they have the same legal treatment.
