Your default currency is the one every total is shown in. Accounts can hold other currencies; this is the currency Finthy converts them into so a dashboard, a net worth or a report adds up to a single number.
It is not a paid feature
Changing your default currency is free on every plan, and so is holding accounts in more than one currency. There is no upgrade step, no locked dropdown and no limit on how often you change it.
If you have read otherwise anywhere, that is out of date.
Change it
- Go to Settings and open the Account tab.
- Find Currency Preferences.
- Set Default Currency. The list holds 54 currencies, labelled by code and name.
- Choose Save Changes. Finthy confirms with “Default currency updated successfully”.
There is also an Income Currency on the same tab, for when your income arrives in a different currency from your default. Left alone it uses your default and says so.
What changes when you switch
- Every total is recalculated into the new currency. Dashboard figures, net worth and report totals all convert.
- New accounts and budgets start from the new currency, though you can still pick another for each one.
- Existing accounts keep their own currency. This is the important one: switching the default changes what totals are displayed in, not what any account or transaction is recorded in. No underlying amount is rewritten.
- Past transactions keep their own currency too, and are converted using the rate for their own date rather than today’s.
So switching is reversible and safe. Switch back and every total returns to what it was.
The account list is shorter than the default list
Worth knowing, because it surprises people: the default currency offers all 54, but when you create an account by hand the currency picker offers 11: MXN, USD, EUR, CLP, COP, PEN, BRL, ARS, GBP, CHF and CAD.
So you can set your default to a currency you cannot yet assign to a new manual account. The totals still work; it is the per-account choice that is narrower.
Good to know
- A budget keeps its own currency. Changing your default does not re-denominate an existing budget, so a budget set in one currency keeps reporting in it.
- If a currency the bank uses differs from the account’s, Finthy warns when you create the account rather than silently converting.
- Changing the default does not change your language. They are separate settings on the same tab.
