To track spending while traveling, log expenses in the local currency right after you pay, without doing the math in your head. Budget will convert the amount into your budget currency using the day's exchange rate. That way, by the end of the trip you'll see exactly how much it cost, not just what's left on your card.
Why is expense tracking the first thing to break down on a trip?
At home, spending is familiar: the same shops, the same amounts, prices you understand without calculating. Traveling is different. Every purchase is in a foreign currency, and to tell whether it's expensive or not, you have to do the math in your head. After a couple of days, you get tired of calculating, and expenses stop getting noticed.
On top of that, there's cash that never shows up in your banking app, tips, small on-the-go purchases, and card charges that post later. The real total of the trip only becomes clear at home, from the statement, when it's too late to change anything.
One week of travel
Imagine a week in Europe with a budget in dollars. Day one: coffee at the airport, a taxi to the hotel, dinner. Instead of doing the math in your head, you send one message: "taxi 35 euros and dinner 45 euros." Budget logs both expenses, converts them into dollars, and instantly shows how much is left of your monthly budget.
On day three, a big purchase at a store. The receipt is long, so you just take a photo of it. Budget reads the total and currency straight from the receipt. On day five, a walk through the market: your hands are full, so you send a voice message, "souvenirs twenty euros." By the end of the week, you have the full picture: how much went to food, transport, and shopping, all already converted into dollars.
How to log expenses in the local currency
Mention the currency in every entry: "lunch 18 euros," "massage 400 baht," "coffee $4." Budget will convert the amount into your budget currency and show both figures, for example "€45 ≈ $49." The exchange rate updates once a day, so the "≈" sign is there for a reason: your bank will charge you at its own rate and may add a fee.
The main trap abroad: an amount with no currency. If you just write "lunch 18," Budget will log it as 18 in your budget currency, meaning $18. While traveling, make it a rule to always specify the currency, even when it seems obvious.
What to keep in mind before, during, and after the trip
Budget works with a single monthly budget, there's no separate budget for trips. So it's best to fold the trip into your month: account for it in your budget amount ahead of time, then review expenses by category afterward.
When | What to do | How in Budget |
|---|---|---|
Before the trip | Add the trip to your monthly budget | /budget with the new amount |
Every day | Log expenses with the currency | Text, voice, or a photo of the receipt |
In the evening | Check your balance | /balance |
After the trip | See what the money went on | /stats and the /export report |
If the trip lasts longer than a month, the summary on the 1st will show expenses for each month separately, and the /export report will arrive as a separate file for each month.
Frequently asked questions
What exchange rate does Budget use to convert currency?
The average market rate, updated once a day. The amount in your budget currency is approximate, which is why it's marked with "≈". When you pay by card, your bank applies its own rate and sometimes a fee, so the actual charge may differ slightly. For keeping your travel budget under control, this level of accuracy is enough. It's the overall picture that matters, not the exact cents.
What happens if you forget to specify the currency?
Budget will log the amount in your budget currency. For example, "coffee 4" with a dollar-based budget becomes four dollars. It's easy to fix: delete the last expense by sending "delete," then send it again with the currency included. It's best to get in the habit of writing the currency in every entry while you're abroad.
Can you photograph a receipt in a foreign currency?
Yes. Budget reads the total amount and currency if it's printed on the receipt as a symbol or code, or if it's clear from the country. It then converts the amount into your budget currency and picks a category. If the currency isn't visible on the receipt, it's more reliable to send the expense as text with the currency specified.
How should you track cash withdrawn from an ATM?
Don't log the withdrawal itself, log the actual cash purchases: "market 15 euros," "taxi 20 euros." Withdrawing cash is just moving money around, not spending it, and if you log both the withdrawal and the purchases, expenses get counted twice. The ATM fee can be logged as a separate expense since it's a real cost of the trip.
Should you change your budget currency for the trip?
Usually not. It's more convenient to keep your budget in your home currency and specify the local currency in each entry, that way the trip stays comparable to your regular months. If you're going away for a long time and living on local income, you can change your budget currency with the /currency command, but past expenses won't be recalculated.
What's next
Before your next trip, add it to your monthly budget and log your first expense right at the airport, with the currency included. Open Budget and send, for example, "coffee 4 euros" to see the conversion. To learn how to stay within budget, check out the tips section.
