Travel costs people forget to budget for

15 October 2026 · 5 min read

Hotels, food and getting around are easy to remember. The costs that break budgets are the small, scattered ones: each looks minor, but together they can add a large share to a short trip. Here are the ones we see forgotten most often, so you can add them up front.

Before you go

• Visa and entry fees. Many countries charge for a visa, an e-visa or an electronic travel authorisation, even for short visits. Check the rules for your passport, not just the destination.
• Travel insurance. Worth budgeting for every trip. The price depends on your age, the length of the trip, where you’re going and what’s covered.
• Vaccinations and medicines. Some destinations recommend or require vaccinations, and they’re rarely free.
• Getting to your departure airport or station, parking there, and anything you pay at home while you’re away, such as pet sitting.

Getting there and back

• Bags and seats. Low-cost airlines often charge separately for checked bags, cabin bags and choosing a seat. Compare fares with the extras you’ll actually need.
• Airport transfers. A taxi from the airport can cost as much as a night in a budget hotel. Look up the airport train or bus before you land.

While you’re there

• Tourist and city taxes. Many cities add a nightly tax per person, often paid at the hotel and not always included in the price you booked. Some hotels also add resort or service fees.
• Mobile data. Roaming can be expensive. A local SIM or an eSIM is usually far cheaper; budget for one per traveller who needs data.
• Card and cash fees. Foreign transaction fees, ATM charges and poor exchange rates are a quiet drain. See spending money abroad for how to keep them down.
• Tips and service charges. Customs vary a lot: in some countries a tip is expected, in others a service charge is added to the bill, and in some tipping isn’t done at all. Find out before you go.
• Entry fees and reservations. Museums, temples, viewpoints and national parks often charge entry, and popular ones may need booking ahead.
• Transport cards. Some city transit cards need a deposit or an initial top-up.
• Laundry, adapters and small kit. Longer trips usually mean paying for laundry at some point, and a plug adapter if your devices don’t fit local sockets.
• Souvenirs and treats. Not essential, but rarely zero. Decide on an amount rather than leaving it open.

How to budget for them

Most of these are one-off amounts rather than daily costs, so add them as a single “other” line. In the TravelWise trip cost calculator, use the Other line for visa fees, insurance, getting there and anything else, and it’s added to your total. Then keep a buffer of 10–15% for the things nobody can predict.
