Travel budget: how to work out what a trip costs and stick to it
A trip rarely costs what you expected. Not because of the flights or the hotel, which you know in advance, but because of everything else: meals, taxis, tickets, card fees. A travel budget does two jobs: it tells you whether the trip fits your finances, and it tells you, while you're away, whether you're on track.
The short answer
Estimate the cost block by block, add a margin for the unexpected, record spending as you go, and when you're back compare what you planned with what you spent. That comparison is what makes the next budget better.
The blocks of a trip
Split the trip into blocks and estimate each one separately:
- Getting there and back: flights, trains, driving (fuel, tolls, parking).
- Accommodation: the total for every night, including tourist taxes.
- Food: an amount per day per person. This is the block that most often falls short.
- Getting around: public transport, taxis, car hire.
- Activities: tickets, day trips, guided tours.
- The forgotten extras: travel insurance, fees for paying in another currency, tips, souvenirs, the extra bag.
Multiply the daily amounts by the number of days and add the one-off costs. With made-up figures: 4 days at 60 for food and 20 for local transport is 320, plus 280 for flights, 360 for accommodation and 100 for activities, 1,060 in total.
A margin for the unexpected
Add 10 to 15% on top. It isn't pessimism: there's always something that wasn't on the list, a pricier meal, a late taxi. If you don't spend it, all the better. In the example, 10% takes the budget to about 1,170.
If the trip isn't paid for yet, divide the total by the months until you leave. That's what you'd need to put aside each month. It fits alongside how much you should save each month.
Spending in another currency
When you travel abroad there are two temptations: converting every expense by hand, or not recording it at all. What works is:
- Record the amount in the currency you paid. It's the figure on the receipt, and there's nothing to work out on the spot.
- Convert at the end to see the total. With the exchange rate, the whole trip adds up in your own currency.
In abacova, each account has its own currency and you choose which currency to see totals in. Exchange rates do the conversion. If a total mixes currencies that can't be converted, abacova tells you the total is partial instead of showing a wrong number.
Keeping track during the trip
On holiday you don't want to do bookkeeping. One habit is enough: record each expense with a tag for the trip, say "Lisbon 2026".
Food stays in your food category and transport in its own. The tag pulls them all together, so at any point you can see how much the trip has cost so far and compare it with your budget. Why a tag beats a category for this is explained in Trip to Rome is not a category.
If you'd like abacova to keep count for you, create a budget with a line for the trip's tag and the amount you worked out. You'll see planned against spent for the whole trip, and an alert can warn you before you go over.
To go faster, scan the receipt or dictate the expense in one sentence as you leave the shop.
Group trips
If several of you are travelling, one person pays for dinner, another for fuel, another for tickets. Keep a balance per person and settle up when you're home. See how to split expenses with friends.
When you're back: plan versus reality
With every expense tagged, compare block by block:
- Where did you fall short? It's almost always food or local transport.
- What was left over?
- Did you use the margin?
Note the differences. Your next travel budget will start from real figures instead of guesses.
Frequently asked questions
How much margin should I leave? 10 to 15% of the total is a common rule of thumb. More if you're going somewhere you don't know.
Card or cash abroad? It depends on your card's fees. Either way, record both: cash is spending too.
Can I see the trip's total in my own currency if I paid in another? Yes. Exchange rates convert the amounts and you see the total in the currency you choose.
Should I create a category for each trip? Use a tag instead: food keeps adding up under food, and the trip is still visible as a whole.
Can I set a budget for the trip's tag? Yes. A budget can have a line per tag, as well as per category or per account.
