Log expenses across currencies without losing your mind
Multi-country trips break every tracking app. You're in Bangkok spending baht, fly to Tokyo and spend yen, stop in Seoul for 3 nights and spend won, connect through Hong Kong where half the vendors take HKD and half take USD. By the end of a 14-day Asia trip you have $3,600 of receipts in 5 currencies and no idea what your trip actually cost. This logger handles 14 currencies with real-time rates, converts everything to your home currency on the fly, and produces a per-country and total breakdown.
The 14 currencies supported
USD, EUR, GBP, JPY, KRW, CNY, HKD, SGD, THB, VND, IDR, INR, MXN, BRL. Add your home currency as baseline (USD default). Rates update at session start — lock them for the trip or refresh on arrival in each new country. Works for 95% of travel scenarios; handful of African and Middle East currencies need manual entry.
How rates actually work (and why card statements differ)
Mid-market rate: what Google shows you — the wholesale bank-to-bank rate. You will never get this rate as a traveler. ATM rate: mid-market − 0.5 to 1% from your bank (Schwab, Fidelity refund fees; Bank of America adds ~1%). Credit card rate: mid-market + 1–3% (Chase Sapphire at 0% FX still applies ~1% network fee buried in the rate from Visa/Mastercard/Amex). Airport exchange booth: mid-market + 8–15% — never use. Hotel desk exchange: mid-market + 10–18% — never use. DCC (Dynamic Currency Conversion, the "charged in USD" option at restaurant terminals): mid-market + 3–7% added on top of your card's FX fee — always say NO and pay in local currency.
The 3-step logging workflow
Step 1: open app, tap "add expense." Step 2: enter amount in local currency + category (food/lodging/transit/activity/misc) + optional note. Step 3: save — the logger converts to home currency and adds to running total. 20 seconds per expense. Most travelers log 4–8 expenses/day on a typical city day.
Country-level breakdown at trip end
At the end of a multi-country trip, the logger produces: total spent per country in local currency + USD equivalent, total by category across all countries, total trip spend in USD, percentage breakdown. This is the report you should save to evaluate your travel efficiency: "Thailand was $72/day, Japan was $210/day, which aligns with my expectations."
Handling gaps in logging
You miss 2 days of logging — happens. The logger handles this via "catch-up entry": estimate yesterday's total + the day before, mark as estimated. Better than leaving gaps. You can also pull from your credit card app (Chase, Amex, Capital One all show pending transactions in native currency + USD) to reconstruct missed days.
Cash vs card tracking split
Log every ATM withdrawal as "cash added." Then at each cash expense, reduce from the pool. At trip end, remaining cash in wallet means that's the slippage — usually $20–$50 of tips + small purchases unlogged. Card purchases auto-show in statement; for accuracy, reconcile the logger total to the statement total and note the gap (usually 2–5%).
Best cards for multi-country travel
Chase Sapphire Preferred ($95 AF): 0% FX, 2x travel, 3x dining. Capital One Venture X ($395 AF): 0% FX, 2x everything, $300 travel credit. Amex Platinum ($695 AF): 0% FX, 5x flights booked direct, $200 airline credit, airport lounge access. Charles Schwab High Yield Investor Checking debit card: refunds all ATM fees worldwide (the best single travel banking product in the U.S.). Fidelity Cash Management: similar, also refunds ATM fees. Bilt Mastercard: 0% FX, 2x travel, no annual fee.
Edge cases
Prepaid tours (paid at home in USD): enter as $X in USD, mark as prepaid — doesn't double-count at destination. Hotel bill at checkout charged to card (large lump): enter under the date you check out, not each night (matches card statement). Split bills with travel companion: enter full amount, note "split 50/50", halve at reconciliation time or use trip cost splitter separately. Foreign currency you brought back (leftover): don't count as spend.
FAQ on multi-currency expense logging
Offline logging? Yes — works without Wi-Fi, syncs to browser storage. How accurate are the converted totals? Within 2% of your actual card statement if you use mid-market rates. The gap is ATM fees, card FX fees, and the small bid-ask spread. Accurate enough for budget decisions. Exporting data? CSV export at trip end. Open in Excel/Google Sheets for deeper analysis. Can I log in my home currency only? Yes but you lose per-country insight. Should I adjust rates mid-trip if they change? No — set rate at country entry, lock for the duration. Fluctuations over 1–2 weeks are typically 0.5–1.5%, not worth re-converting. What if I travel to a currency not in the 14 supported? Manual rate entry. Google the current rate, enter as a custom currency. Best way to get cash? Schwab + Fidelity debit cards from major-bank ATMs (Kasikorn in Thailand, 7-Eleven in Japan, HSBC in Hong Kong, major banks in Europe). What to do with leftover cash at trip end? Spend it on airport food, save for next trip (euros, yen, baht stay valuable), or convert at Travelex at a loss. How do I budget for tips across countries? Tips practice varies wildly. Budget tips as an annualized 5–10% of food + activity spend and track under misc.
