Mozaic Finance Multi-currency net worth

CAD and USD accounts, one net-worth number

If you hold a US brokerage, a USD chequing account, or foreign cash alongside your Canadian accounts, your real net worth is split across currencies. Mozaic converts each account into one base currency, defaulting to CAD, so the number at the top of your dashboard is the whole picture instead of a pile of separate totals.

Cross-border finances are common for Canadians: RSUs from a US employer, a Robinhood or Schwab account held for tax reasons, USD cash from freelance work, or a currency account at Wealthsimple. The problem is not tracking each one, it is seeing them together. Mozaic solves that by converting every account into your base currency and summing the result into a single net-worth figure.

How the conversion works

Every account keeps its native currency. When Mozaic builds your net worth, it converts each one into your base currency at the current rate and adds them up. Nothing about your USD account changes; it is simply expressed in CAD (or whichever base you choose) for the purpose of the total.

  • Supported currencies: CAD, USD, EUR, GBP, AUD, JPY, and CHF.
  • Your base currency defaults to CAD and is changeable in Settings. It sets the single currency your net worth, holdings, and cash flow are reported in.
  • The total updates as balances refresh and as the daily rate updates, so the headline number always reflects today's value of everything you hold.

How the exchange rate is applied

This is where a lot of trackers overstate what they do, so here is exactly what Mozaic does and does not do.

Current-rate only. Conversions use today's rate, sourced from the European Central Bank's published reference rates through the Frankfurter service and cached once per calendar day. These are mid-market rates, not the retail spread your bank adds on an actual conversion, so read the total as a fair view of value rather than the cash you would net after fees.

No reprojected history. Each point on your net-worth history was calculated at the rate that was live on that day, and then frozen. Mozaic never goes back and re-values old balances at a new rate. That means a rise or fall in your history reflects what your accounts actually did at the time, currency movements included, rather than a retroactive adjustment that rewrites the past. It is a smaller claim than "FX-accurate historical net worth," and it is the true one.

No guessing. If an account is in a currency Mozaic cannot convert that day, the account is left out of the converted total and the day is flagged as a partial conversion, rather than folded in at an invented rate. You always see the account and its native balance; it just does not silently inflate the single-number total.

Where this fits

Multi-currency conversion sits underneath everything Mozaic shows: net worth, holdings, and cash flow are all reported in your base currency.

Frequently asked

Mozaic converts between CAD, USD, EUR, GBP, AUD, JPY, and CHF. You pick one of them as your base currency, and every account in a supported currency is converted into it and added to your net-worth total.
Yes. The base currency defaults to CAD, and you can change it in Settings. Whatever you choose becomes the single currency your net worth, holdings, and cash flow are reported in, with every other account converted into it.
No, and this is deliberate. Today's total uses today's rate. Each point on your net-worth history was recorded at the rate that was live on that day and then left alone. Mozaic does not go back and reproject old balances at a new rate, so a move in your history reflects what actually happened at the time, not a retroactive currency adjustment.
From the European Central Bank's published reference rates, retrieved through the Frankfurter service and cached once per day. They are mid-market rates, not the retail spread your bank charges on a real conversion, so treat the total as an accurate view of value rather than the exact cash you would receive after fees.
Rather than guess, Mozaic leaves that account out of the converted total and flags the day as having a partial conversion. You still see the account and its native balance; it is only excluded from the single-number total until a rate is available, so the headline figure is never quietly inflated by a made-up rate.
