How to Track Your Net Worth Across Countries and Currencies

If your financial life crosses borders — a salary in one currency, savings in another, maybe property or a pension somewhere you used to live — working out your true net worth is genuinely harder than the guides admit. The maths is simple; the currency handling is where people give up. Here is a method that holds together.

Step 1: List every account in its own currency

Resist the urge to convert as you go. Write down each account at its native value: the euro brokerage in euros, the Thai bank in baht, the dollar Roth in dollars. Include liabilities — mortgages and loans — the same way. Converting too early, in your head or ad hoc, is the single biggest source of a wrong total.

Step 2: Choose one base currency

Pick the currency you actually think in — usually where you live now or plan to retire. Every other balance will be expressed relative to this one. Your net worth only means something as a single number, and a single number needs a single currency.

Step 3: Convert with real rates, consistently

Convert each native balance into your base currency using the current exchange rate, and apply the same rates across the whole snapshot so the total is internally consistent. This is the step a spreadsheet makes tedious — you are hand-maintaining a rate table — and the step a single-currency US app cannot do at all. A multi-currency tracker does it automatically.

Step 4: Snapshot monthly, watch the trend

A one-off number is trivia; the trend is the insight. Record your consolidated net worth once a month. Currency swings will move it around — that is real, and seeing it is the point. Over a year, the trend tells you whether you are genuinely building wealth, independent of which currency happens to be strong this month.

Step 5: Tie it to a goal

A number with no target drifts. Anchor it to something — a FIRE figure, an emergency fund, a house deposit — expressed in your base currency, and track progress against it. That is what turns tracking from a chore into momentum.
