Convert each currency at its own rate first, then add. It sounds obvious and it is the step most spreadsheets get wrong, usually by summing everything and applying a single blended rate at the end. The error grows with how far the currencies have diverged, and it grows silently. A position of €40,000, £25,000, CHF 15,000 and $10,000 is roughly €94,500 at today's rates — but the same list converted carelessly can be several thousand out, which is the difference between believing you have hit a milestone and actually having hit it. Use a published reference rate so the number is reproducible rather than dependent on which provider you asked.

Pick the currency you expect to spend in over the long run and make every total speak in it. The choice matters less than the consistency: a net worth history that switches reference currency partway through is not comparable with itself, and the trend, which is the only genuinely useful output, becomes noise. If you genuinely do not know where you will settle, choose the currency of your largest liability, because that is the exposure most capable of hurting you. Revisit the choice when your life changes materially — a permanent move, a mortgage in a new country — rather than whenever a rate moves.

Most multi-currency exposure is accidental. It accumulates because you lived somewhere, opened an account and moved on, not because anyone decided the allocation. Review it as though it were deliberate: hold enough in each currency to cover that currency's commitments, and be honest about which balances are exposure rather than diversification. Watch for mismatch between an asset and the liability it secures, which is where real damage happens. Note too that in some countries a currency gain is taxable when the asset is sold even though it feels like an accounting artefact, so check the local treatment before assuming a gain is entirely yours to keep.

Net worth = Σ(assets × rate) − Σ(liabilities × rate)
Each balance is converted at the current rate for its own currency, then summed. The order matters: converting first and adding second is the only way the total reflects today's position. Adding first and converting once, using a single blended rate, produces a number that is wrong by however far the currencies have diverged.
Sam holds €40,000, £25,000, CHF 15,000 and $10,000. Converted at today's rates that is roughly €40,000 + €29,300 + €16,000 + €9,200 = €94,500. Against a £180,000 UK mortgage — about €211,000 — the net position is negative, which the unconverted list would not have shown.
Pick one reference currency and keep it. A total that changes reference is not comparable with last month's.
Live rates matter more than most people expect. A quarter-old rate on a six-figure position can be several thousand out.
Watch for currency mismatch between an asset and the liability it secures. A euro salary against a sterling mortgage is an unhedged position whether or not you think of it that way.
Note that unrealised currency gains may still be taxable in some countries when the asset is sold. Check locally before assuming a gain is yours.
Review quarterly. Monthly is noise on a multi-currency balance sheet; annually is too slow to catch a real drift.
