A travel budget planner method built on four numbers, with a real fourteen day comparison of what was planned against what was actually spent.
Most travel budgets fail in the same way. Someone adds up flights and hotels, guesses at food, writes down a round number, then spends 40 percent more and decides budgeting does not work for them. The problem is not discipline. The problem is that the budget was missing three quarters of the real costs.
A travel budget planner that survives contact with a real trip has four parts and takes about an hour to build.
Part one, fixed costs
Fixed costs happen once and do not change with how long you stay. Flights, visas, insurance, vaccinations, a new bag, airport transfers at both ends.
Write the real figure, not the advertised fare. A £39 flight with a cabin bag, a seat and airport transport is £96 by the time you are in the city. That gap is where most budgets die on day one.
Part two, the daily rate
This is the single most useful number in travel. It is what one ordinary day costs in the country you are visiting, covering a bed, three meals, local transport and small entries.
Realistic 2026 daily rates for one person on a budget standard with a private room:
Vietnam £34. Georgia £41. Turkey £46. Portugal £62. Poland £58. Japan £78. Netherlands £104.

Multiply the daily rate by the number of nights. That is the largest line in your budget and the easiest one to control, because it moves with the country you pick and the pace you travel at.
Part three, the trip specific extras
Extras are the things you are travelling for. A cooking class in Hanoi at £22. A permit for a trek at £15. A ticket to a football match at £30. Two long distance trains at £34 each.
List them by name with a price. Never write miscellaneous. A named list can be cut. A vague total cannot.
Part four, the buffer
Add 15 percent of everything above. Not 10, and not zero.
The buffer covers the taxi you take because it is raining, the night bus you skip because you are ill, the shoes that fall apart, and the exchange rate moving against you. Every trip has some of these. If you finish with the buffer unspent, that is money you take home, which is a much better feeling than borrowing against next month.
Track spending in a way you will keep doing
Detailed tracking apps get abandoned by day four. What works is a single note on the phone with one line per day and one number. Total spend, nothing else.
Every three days, add the numbers and compare against the daily rate. If you are running 20 percent over, you have two levers. Stay longer in one place to cut transport and get weekly room rates, or move the food budget down by taking lunch as the main meal.
Both levers work. Cutting the number of paid activities usually does not, because those are the reason you came.
Where budgets leak
Airport arrivals. The first hour in a new country is the most expensive hour of the trip. Look up the public transport option before you land.
Card charges. Paying in your home currency at a card machine costs 3 to 5 percent. Always choose local currency. Non network cash machine fees run £2 to £4 a time, so withdraw larger amounts less often.
Drinks. Three beers a night at £4 is £84 over a week, which is two extra nights of accommodation in most of eastern Europe.
Laundry by weight versus by item. By weight is £4 for a full bag. By item at a hotel is £18 for the same clothes.
Booking fees and seat selection. Budget airlines make more from extras than from fares. Decide in advance whether you are paying for a seat, then stop reading the upsell screens.
The receipt
The table shows a fourteen day trip through Spain and Portugal. The planned column was built with the method above. The actual came in £46 under, entirely because the buffer was only half used.
The two lines that ran over were food, because we ate out more than planned in San Sebastian, and transport, because a strike meant one flight became a train. The two lines that came in under were accommodation, from booking direct for the longer stays, and activities.
A worked example you can copy
Ten days in Georgia for one person.
Fixed costs: return flights £182, insurance £24, airport transfers £8. Total £214.
Daily rate: £41 times 10 nights, which is £410.
Extras: wine tour £26, two intercity marshrutkas £14, museum entries £12. Total £52.
Subtotal £676. Buffer at 15 percent, £101. Budget £777.
The actual trip described in three weeks in Georgia ran at £30 a day over a longer stay, which shows how the daily rate falls when you stop moving so often.
Currency, cards and the cost of moving money
Exchange rates are a real line in the budget and most people never count them. A card that charges 2.75 percent in foreign transaction fees on a 1200 pound trip costs you 33 pounds for nothing. Airport bureau rates are typically 8 to 12 percent worse than the mid market rate. ATM operators abroad often add a fixed fee of 3 to 5 pounds plus an offer of conversion at their own rate, which you always decline by choosing to be charged in local currency.
The fix is boring and effective. Carry two cards from different providers with no foreign fees, withdraw larger amounts less often, and always pay in the local currency. That alone protects roughly 3 percent of the entire budget, which on most trips is more than you would save by downgrading your accommodation.
Reviewing the budget while you travel
Do a five minute review every third evening. Add up what you have spent, divide by the days elapsed, and compare it against your daily rate. If you are 10 percent over, you have time to fix it with two cheaper dinners and one free day. If you wait until day ten to look, the only fix left is cutting something you were looking forward to.
Keep one number in your head instead of many, which is what you have left divided by nights remaining. It is the only figure that changes decisions in the moment. The budget travel tips guide covers where the cuts hurt least.
Frequently asked questions
How much should I budget for a two week trip in Europe? Between £850 and £1,600 depending on the country. Portugal, Poland and Greece sit at the lower end. France, Switzerland and the Nordics at the upper.
Should I budget in pounds or the local currency? Budget in pounds so you can compare against your income, but check prices in local currency so you notice when something is expensive by local standards.
How do I budget when I do not know how long I will stay? Use the daily rate and set a stop number instead of an end date. When spending hits the number, you go home or you slow down.
Is a spreadsheet better than an app? A spreadsheet you built yourself is better, because you understand every line. Any app you actually open daily beats a spreadsheet you ignore.
What percentage of the budget should be accommodation? Roughly 35 to 45 percent on a budget trip with private rooms, less if you share or stay long enough for weekly rates.
How much cash should I carry? Enough for two days plus the airport transfer, in small notes. The rest stays on cards. Guidance on the practical side is in how to plan an international trip.
Once the budget exists, the trick is keeping the trip pleasant while it holds. That is covered in budget travel tips that do not cost you comfort.
