How to budget across AMD, USD, and EUR

One budget needs one reporting lens

If you earn, save, and spend in several currencies, adding raw numbers together gives nonsense: 20,000 AMD + 100 USD is not 20,100 of anything. A useful multi-currency budget keeps the original amount and currency on every record, then converts it into one base currency for totals and comparisons.

Choose the currency you use for most everyday decisions. For someone living in Armenia, that may be AMD even when salary or savings arrive in USD or EUR. If your financial life is centered elsewhere, USD or EUR may be more useful. The choice changes the reporting view, not the original transactions.

Set up accounts by real currency

1. Choose the base currency.Use the currency in which you plan rent, groceries, and monthly category limits. Avoid switching it just because exchange rates move.
2. Create accounts that match reality.Examples: “Cash AMD,” “Salary USD,” and “Travel EUR.” Do not create a new account for every trip or merchant.
3. Record opening balances.Enter each balance in its native currency on the same date, then check the converted net total.
4. Set category budgets in the base currency.This gives food, transport, home, and savings targets one comparable scale.
5. Preserve transaction currency.A €30 dinner remains €30 even if the monthly report shows its AMD equivalent.

Use exchange rates consistently

There is no single perfect rate for every purpose. A reference market rate is useful for a current portfolio view; the rate actually applied by a bank, card, or exchange office is better for explaining a completed conversion. Fees and spreads can make those values differ.

• For a purchase: if the card statement shows the settled amount in your account currency, use that amount where possible.
• For cash conversion: record the two real amounts exchanged. Their ratio is the effective rate.
• For current balance reports: use a consistent reference rate and show when it was updated.
• For old reports: avoid silently rewriting history with today’s rate. A report should make its rate method clear.

Small card authorization differences can settle later. Update the expense after settlement instead of creating a second transaction.

A currency exchange is usually a transfer

Moving your own money from a USD account to an AMD account is not income and spending. Record it as one linked transfer: money leaves USD and arrives in AMD. If you paid a conversion fee, record the fee separately as an expense.

Example: you exchange $100 and receive 38,500 AMD. The transfer carries those two amounts and implies an effective rate of 385 AMD per USD. If the service charges 500 AMD separately, categorize only that 500 AMD as a fee. Otherwise your reports may falsely show $100 of spending and 38,500 AMD of income.

Read reports without losing context

Use base-currency totals to answer “How much did I spend this month?” Then inspect original currency when you need to understand a particular account, merchant, or trip.

• Show the selected base currency beside every aggregate total.
• Keep original currency visible in transaction detail.
• Separate spending changes from exchange-rate changes.
• Compare category behavior over time using the same conversion method.
• Do not treat an unrealized currency gain as spendable monthly income.

A simple three-currency month

Suppose your base currency is AMD. You receive a $1,000 payment into a USD account, pay 180,000 AMD for rent, spend €45 while traveling, and exchange $300 into 115,500 AMD.

• The $1,000 remains USD income, with an AMD reporting value using your selected method.
• The 180,000 AMD rent needs no conversion.
• The €45 purchase remains EUR and receives an AMD reporting value.
• The $300 → 115,500 AMD movement is a transfer, not new income or spending.

Your category report converts the rent and travel expense into AMD. Your account view still shows the actual USD, AMD, and EUR balances. That separation keeps both budgeting and reconciliation understandable.
