Most people answer "can I afford this trip?" with a guess. It tends to go the same way every time: the big costs get remembered, the small ones pile up unnoticed, and the gap quietly lands on a card after you're already home. The fix isn't complicated — it's adding up everything, honestly, before you commit to anything.
Why trips go over budget
Underbudgeting is the single most common travel-money mistake, and it's rarely the big purchases that do the damage. You remember the airfare and the room because you booked them deliberately. What slips through is the steady drip of smaller things: the airport transfer, a checked bag, tips, a data SIM, museum tickets, a couple of nicer dinners, drinks in the heat. None of them feels like much on its own. Added across a week or two, they're often the difference between "on budget" and "a few hundred over".
The other trap is comparing destinations on the wrong number. A cheap flight to an expensive city can easily cost more overall than a dearer flight somewhere your daily spending is half as much. The only fair way to compare two trips is total cost, per person, per day — flights included. That's the number worth working out before you fall in love with a fare.
The seven things a real budget includes
A budget that holds up covers more than flights and a bed. Here's each piece, with rough ranges to anchor your thinking — always check current prices for your own dates and destination, because they move with season and demand.
1. Flights
Usually the biggest single line for long-haul travel, and the most volatile. Booking international fares three to six months ahead tends to balance price and choice; set a price alert early so you recognise a genuinely good fare when it appears, and stay flexible by a day or two if you can.
2. Accommodation
Typically your second-largest cost, and the one with the widest range — a dorm, a mid-range hotel and a beachfront resort in the same city can differ tenfold. Because it's such a big share of the total, check real prices for your dates before you settle on a figure rather than guessing. Free-cancellation rates give you room to adjust if plans change.
3. Food and drink
Easy to underestimate, especially if you eat out for every meal. A useful habit is to picture a realistic day — coffee, a casual lunch, a sit-down dinner, a drink or two — and price that, rather than hoping it averages out low.
4. Activities and tours
Where trips become memorable, and where budgets quietly blow out if you decide everything on the spot. List the two or three experiences you genuinely care about and look up their prices in advance so they're in the budget from the start.
5. Local transport
Airport transfers, metro and bus fares, intercity trains, the occasional taxi. Multi-day passes often beat single tickets, and walkable accommodation can shrink this line a lot. Budget a daily figure rather than trying to predict every journey.
6. Travel insurance
Treat it as a fixed cost, not an optional extra — medical care and evacuation overseas can run into the tens of thousands. It's a small, known number that protects against a catastrophic one.
7. A buffer
Add 15–20% on top of everything for exchange-rate movement, price rises, a missed connection, and the spontaneous yes you don't want to refuse. The buffer is what keeps one surprise from derailing the whole trip.
Now put your own numbers in
Once you've got a rough figure for each category, drop them into the tool below. Set your trip length and group size, and it returns a realistic total — broken down per person and per day. No exact numbers yet? Use sensible estimates and refine as plans firm up.
Add up your trip → per person & per day
A planning estimate, not a quote. The per-day figure is your best sanity check — if it looks off for where you're going, adjust until the trip feels real.
How to read your number
The total matters, but the per-day figure is what tells you whether the trip is realistic. If it's lower than the rough daily ranges for your destination, you've probably missed something; if it's much higher, look at where — usually accommodation or activities — and decide whether that's a choice or an oversight. This is also the number to divide into a savings target: knowing you need, say, a set amount per month makes a trip feel bookable instead of vague.
Ways to bring the number down
- Travel in shoulder season. The weeks either side of peak often bring much lower flight and hotel prices with similar weather and thinner crowds.
- Pay smart overseas. A no-foreign-fee card plus a little local cash beats airport kiosks; decline "pay in your home currency" at terminals.
- Book the big activities early. Key tours and tickets are often cheaper ahead and guaranteed a spot in peak season.
- Set a daily target. Turning the budget into a per-day number makes it easy to stay on track once you're there.

Questions
How much should I budget for a trip?
As a rough guide, daily on-the-ground spending runs about AUD 50–90 a day in Southeast Asia, AUD 120–200 in Western Europe and Japan, and AUD 130–220 in North America for a comfortable mid-range trip. Add return flights and a 15–20% buffer, then use the tool for your own total.
What should a travel budget include?
Flights, accommodation, food and drink, activities, local transport, travel insurance, and a buffer. Most people remember the big items but forget the small recurring ones — transfers, tips, SIMs, baggage fees.
How big should my buffer be?
15–20% of the total suits most trips. It covers exchange-rate movement, price rises, a missed connection or a spontaneous yes. Longer and more remote trips warrant a bigger one.
Should I buy travel insurance?
For overseas travel, yes — medical care and evacuation abroad can cost tens of thousands, and it also covers cancellations and lost luggage. Treat it as a fixed line, and read what is and isn't covered.
What's the cheapest way to pay overseas?
A no-foreign-fee travel or multi-currency card plus a little local cash. Avoid airport exchange kiosks for large amounts, and decline "pay in your home currency" at card terminals.
