Мультивалютний бюджет — це шар перекладу, а не гарантія ідеального курсу. Оберіть базову валюту, збережіть початкову суму та запишіть розрахункову суму й комісію.
ЄЦБ називає довідкові курси інформаційними, а не гарантованим курсом картки. Gunakan kurs referensi untuk menjelaskan perbedaan dan jumlah pada penyata untuk menyemak apa yang benar-benar berlaku.
Оберіть базову валюту для рішень
Gunakan mata wang yang dipakai untuk sasaran bulanan dan kewajipan tetap terbesar. Jika pendapatan dan sewa berbeza, pilih mata wang yang paling jelas untuk keputusan kos tetap.

| Field | Example | Why it matters |
|---|---|---|
| Date and source | 12 June, card statement | Rate can move before settlement |
| Original amount | 1,200 PLN | Keeps the charge visible |
| Settled base amount | €280.40 | Reconciles the budget |
| Reference comparison | €278.90 | Explains, not replaces, the rate |
| Fee or spread | €1.50 | Keeps conversion cost visible |
Розберіть приклад подорожі й доходу
Suppose a €2,000 base budget includes 1,200 PLN rent, 500 USD freelance income, and a £40 travel purchase. Enter original amounts first, then settled base amounts from statements, with date, fee, and refund.
Відокремте довідковий та застосований курс
The ECB reference rate is a comparison point. A bank, card network, cash exchange, or payment provider may apply another rate, spread, fee, or settlement time. The difference is not automatically an error.

- Reconcile weekly during travel or relocation.
- Keep an FX buffer for fees and movement.
- Review fixed obligations when affordability changes.
- Do not trade to fix a budget. A budget records choices, not an investment strategy.
Показуйте дві суми за потреби
Show original-currency totals for each account and base-currency totals for planning. This prevents a rate move from looking like a change in rent, salary, or quantity.
Чого не пояснює конвертація
A reference conversion cannot reconstruct a card spread, cash fee, tax, settlement delay, or refund timing. Currency movement also does not explain every change in a cross-border household’s cost of living.
- Do not call a reference rate the card rate.
- Do not hide fees inside unexplained rounding.
- Check the source before calling an FX difference a budget failure.

A spreadsheet is enough for one foreign account. An app helps with categories and shared access. A bank connection reduces entry but still needs original amounts, fee checks, refunds, and corrections.
Як Lumy збереже запис
Lumy can organise manually entered expenses and category totals. It is not a live FX quote and cannot guarantee every provider fee is known. Check the current plan.
Наступний крок: звірити десять валютних рядків
Choose ten recent foreign-currency transactions. Add original amount, settled base amount, date, source, fee, and refund status. Investigate the three largest differences before changing the monthly budget.
