Budgeting in two currencies: a practical guide for expats and remote workers

Millions of people live with more than one currency: workers in the Gulf sending money home, remote workers paid in dollars, students abroad, families split across two countries. A normal budget assumes one currency. Yours needs a few extra rules.

Pick one base currency for the budget

Your budget needs one currency to add everything up in. Choose the currency you spend most of your money in, usually the one where you live. If you live in Dubai and are paid in dirhams, the base is AED, even if you send part of your salary to Pakistan or Egypt.

If you are paid in one currency and live in another (paid in USD, living in Lisbon in euros), you can still use the local currency as the base. Convert your income into it when it arrives, at the rate you actually got.

Record each expense in the currency you paid

This is the most important rule. When you spend, record the amount in the currency you paid, plus the exchange rate on that day. Then your budget converts it into the base currency once and keeps that value.

Why not just convert everything at today's rate when you look at the month? Because exchange rates move. If you converted last month's spending at today's rate, your past would change every day. A coffee that cost you 15 dirhams in March should still say 15 dirhams in May.

Worked example

You live in the UAE and budget in AED. The dirham is pegged to the US dollar at 3.6725 AED per USD, so dollar expenses are easy. You also pay for a family member's school fees in another currency.

The PKR rate here is only an example; rates change every day. For payments abroad, the best "rate" to record is what you were actually charged, including fees, because that is what left your account.

Money you send home

• Treat regular transfers as a fixed bill. Set them aside on payday, the same as rent, so your daily spending number is not inflated.
• Compare the amount received, not the fee. A "zero fee" transfer with a poor exchange rate can cost more than a small fee with a good rate. Compare how much arrives on the other side.
• Send on a schedule. Trying to time the exchange rate usually costs more stress than it saves money.

Plan for exchange-rate swings

If you earn in one currency and pay big bills in another, a move of a few percent can matter. Two simple protections:

• Add a buffer of 2–5% to budgets for bills paid in a foreign currency.
• Keep a small balance in the currency you pay big bills in, if your bank allows it, so you are not forced to convert on a bad day.

Trips and shared costs abroad

On a group trip, record shared expenses in the trip currency and save the rate with each one. When you settle up at home, everyone's share is based on what was really paid, not on one end-of-trip rate. See how to split shared expenses fairly.

A daily limit works in any currency

Once income and bills are in your base currency, the daily spending limit works exactly the same: money left for spending ÷ days left. The currency is just the label on the number.

RatePocket was built partly for this: it has a currency converter whose rates refresh every few minutes, and it saves the rate with each entry, so past spending never changes when rates move.
