Argyo AppsBudgeting for foreign-currency purchases
Updated: 2026-10-18 · By Andrei and Nada Argyo, creators of SwissBudget+ in Lucerne.
Travel and online purchases can be priced in another currency. Keep your household budget readable by recording the amount charged in CHF and retaining the original receipt.
Keep the receipt
Note the purchase date, original currency and the CHF amount shown by your card or receipt. This gives you a clear record without guessing an exchange rate later.
Use one home-currency budget
Compare spending in CHF with your regular categories. If a refund or card adjustment arrives later, update the expense so the budget matches the final charge.
Record the CHF amount
SwissBudget+ lets you book a foreign-currency purchase in CHF. Your budget stays in your chosen currency and the entry is ready to compare with other expenses.
