Two currencies as a couple: a simple system that works

Living between two currencies is common: one currency for income, another for expenses, or different currencies across accounts. The problem is not the currencies—it’s mixing them.

Here’s a simple system that keeps your numbers clear.

1) Keep accounts in their native currency

Don’t convert everything to one currency. Keep Currency A accounts in Currency A, and Currency B accounts in Currency B. This preserves accuracy and avoids hidden loss from constant conversions.

2) Separate totals (never combine by default)

Track totals by currency. You can compare, but don’t add them together unless you intentionally convert at a visible rate.

3) Use a shared routine

Pick a short monthly check-in where you:

• Review balances by currency
• Compare expected vs. actual totals
• Decide on next month’s transfers or savings

4) Agree on a “reference currency”

For decisions that need one number (like a budget cap), choose a reference currency. Use a live rate at the moment you need it and make the conversion visible.

5) Automate what you can

The best system is the one you actually use. A shared dashboard that keeps currency totals separated saves you from constant manual math.

Managing two currencies doesn’t need to be stressful. With clear separation, a short routine, and shared visibility, you can make confident decisions together.
